Zeke Emanuel (a physician, medical ethicist, and policy wonk) has some different ideas for how to lead a healthy and meaningful life. It starts with ice cream. (Part three of “The Freakonomics Radio Guide to Getting Better.”)
Hosted by Simplecast, an AdsWizz company. See pcm.adswizz.com for information about our collection and use of personal data for advertising.
The global wellness industry is estimated at around $7 trillion and it's growing fast.
I guess you could see that as a great thing that so many people have so many resources
to devote to their well-being.
We should say that what the industry counts as wellness can extend pretty far, from
anything to do with your sleep, to home cold plunges, from high protein everything,
to biohacking with untested peptide injections from Chinese labs.
Before there was social media or podcasts, books were the primary vehicle for spreading
the wellness gospel and there are still thousands of books published in the space every year.
But the book we're talking about today has a title that may seem out of sync with the
current wellness trends.
What's your ice cream is the name?
That is Ezekiel or Ezek Emanuel.
He has been on the show before talking about GLP-1s and the dysfunctional American health
care system.
He has been a key player in that system.
He is an oncologist, bioethicist, a professor at the University of Pennsylvania and a policy
maker who helped draft the Affordable Care Act.
In his new book, he argues that most wellness advice today manages to be both too complicated
and too simplistic.
A lot of the wellness gurus and influencers out there, they have to get on social media daily,
they have to write something and they make things way too complicated because they have
to have something, quote unquote, new to bring people back.
They're too simplistic because most of these wellness things are just focused on the physical
and sort of downplay other things.
So how does he see wellness?
Wellness is a lifestyle.
It's something you're going to have to do for decades and it should be something that
easily becomes habitual and that you actually enjoy.
Enjoy?
But what about the suffering, the deprivation, the never-ending search for the perfect
collection of self-care tools?
Today, in the next installment of the Frekenomics Radio Guide to getting better, Zeke Emanuel
offers a different map to the same destination.
So last night, I had a piece of Bobka cake for dessert with a scoop of very nice ginger
ice cream.
It was wonderful.
Are you ready to get on board the Bobka train?
It's leaving the station now.
This is Frekenomics Radio, the podcast that explores the hidden side of everything with
your host, Stephen Dubner.
Zeke Emanuel, as a pair of brothers, who have also been on this show before, the politician
Ram Emanuel, who is currently flirting with a 2028 presidential run, and the sports and
entertainment mogul Ari Emanuel.
The way Ari pursues wellness might fall into what Zeke calls the complicated category.
Here's Ari on the show a couple years ago, and I asked him to describe his fitness routine.
How long does this podcast last?
I mean, it's so stupid what I do.
I'll give you this morning.
I woke up, I think, 4.45.
I take either, depending on day, Thai helmets or UK helmets, which are live microbes for
my gut.
I then get a cup of coffee.
Today I did bike hypoxia training.
I sprint on the bike for a minute at a very high level, take it down to a very low level,
put a mask on that takes me up to 22,000 feet for 3 minutes.
I do that for 25 minutes.
Then today I did a weight program, chest, tri-shoulders, legs, and stomach.
Then I went in.
I did a sauna.
I'm meditated for, I think today was 17 minutes, got a nice bath for 4 minutes, steam, got
out, take my vitamins.
Then, usually Fridays I don't eat, I'll have dinner, Thursday night, won't eat until Friday
night.
The wellness craze that were in says a lot about the social moment that were also in.
And that again is older brother Zeke, a manual.
About 150 years ago, in 1870, there was this enormous well spring of interest in wellness
also, with lots of books and new magazines and exercises.
It was the result of rapid urbanization, a lot of immigration, consequent xenophobia,
and a lot of economic inequality, the Vanderbilt, the Rockefeller's the Carnegie's, and a
lot of poor people, questions about the integrity of food, so updinson's clear, the jungle.
We're in exactly the same moment, including the gilded age.
We've got the gilded age.
We've got a lot of immigration, consequent xenophobia, people worrying about the food
supply in terms of ultra-processed foods, and the world-feeling tapsy-turvy, like people
can control their own environment much less the direction of their lives.
What you have is, I think, people looking inward like, what can I control?
My wellness, my own life is something I control.
Back then, we had books like The Manual of Hygiene, which was an exercise book or the new
science of healing.
We had my system of 15-minute daily workout, and now we have The New York Times, you know,
seven-minute daily workout.
Okay.
The full title of your book is Eat Your Ice Cream, six simple rules for a long and healthy
life.
Tell me how this book came into being and why?
The reason it came into being is that I began doing work on this book, and one of the
things that I became much more convinced of is the importance of dairy.
And then several years ago, there was this article in the Atlantic about ice cream being
actually good for you.
And when you uncover and chase that down, you know, dairy has a lot of advantages.
If you eat dairy as a young kid, societies that eat a lot of dairy, generally taller,
you actually get a lot of protein from eating dairy.
By the way, dairy is also good at preventing colon cancer.
It's good at many other things.
Now, there are some downsides to dairy, and one shouldn't hide them.
It's high in saturated fats, but it does appear that those saturated fats are not used
by the body in the same way.
There was just a recent report of cream and full fat age, Jesus actually decreasing risk
of dementia.
So in general, dairy has, I think, been undersold in American society.
Ice cream is a good thing, not only because it's this dairy component, but it also is this
joyous component.
And we don't have to lead our lives in self-denial.
I can't have that ice cream.
So last night, I had a piece of bopka cake for dessert with a scoop of very nice ginger
ice cream.
It was wonderful.
And you're still alive to speak with me, amazing.
But only that.
I'm thrilled.
It was a great evening.
You just mentioned a few things about dairy, preventing colon cancer, perhaps warding
off for delaying dementia, also diabetes.
And diabetes.
Okay.
I want to ask you about these concepts generally, because you write in this book about
a lot of benefits or associations with different foods, behaviors, exercise, and so on.
But let's just back up for a minute and address a fundamental question I have, which
is in the health care realm, especially in the nutrition realm, but even in exercise
and even in medicine, I feel like there's a lot of operating on associations, right?
Eating more dairy is associated with a lower rate of colon cancer, let's say.
You write that there's an association between loneliness and premature death.
And what I want to get at, Zeke, before we get into the particulars of your argument
about the book is, how reliable you feel these associations are?
Because as you know well, when you hang out with economists, an association or a correlation
is a very nice step in the right direction, but it doesn't fill in the entire sentence.
So it could be that sicker people, for instance, are lonely because when you're sick, you
have a much harder time having social circles and so on.
And not that loneliness makes you sick, which I think is the conclusion that a lot of
people will come to when they read findings like that.
So can you just talk for a moment about, let's say the strength of evidence throughout
your book with associations versus something that might be established as purely causal?
Yeah, my daughter is an economist and pounds on me all the time that in economics, you
do associations and you're not getting into the top five journals and therefore you're
not getting tenure and you can forget all about it.
So I understand it's the economics part of the free economics that we're now in.
So first of all, well, to be fair, even if I were not a fan of economists and economics,
I would say that it's a good thing to establish cause in as airtight a way as possible because
look, here's an example, when it rains, you see a lot of people out there with umbrellas.
If I came down from Mars and I saw all these umbrellas every time there was rain, I think,
no, if people had only put away their umbrellas, it would stop raining.
They must be causing it.
That's a very good association, but it's not causal.
You're 100% right.
Association is not causation and you need to be careful and we make mistakes.
On the other hand, many of these issues like diet, you can't do the randomized trial
or you can do a randomized trial for a short amount of time.
So you're not going to be able to do the causal studies.
The second thing I would say is if you get multiple studies in multiple different contexts
in multiple countries, you begin to believe it.
And then if you have a plausible biological mechanism, you begin to believe it as well.
A lot of these associations, they've begun to look mainly in the UK biobank study and
see the molecular mechanisms by which, for example, loneliness turns on certain genes.
Those genes actually cause chronic inflammation and you have a mechanism that begins to make
sense.
So I'm totally with you.
If I had one association study, I would say, oh, yeah, you're right.
Once you've got a lot going in the same direction and you have a plausible biological mechanism
and you're beginning to tease out the genes that are involved, I'm more likely to believe
it.
Many of the predictions I say turn out not to be right.
Yeah.
Diet is one of those things, okay, take butter as an example.
Butter was evil for about 20 years there, wasn't it?
Butter has been very negative, saturated fats, blah, blah, blah.
And my mother cooked only with margarine, right?
And then guess what?
Well, if you use butter, it's got the saturated fat.
But then if you substitute margarine, it's even worse.
And so one of the things about diet that is very important, it's not just the thing you
eat.
It's also what is it substituting for?
It's the alternative that you might adopt.
We often don't think that way.
So we only think of one category of food, not the entire diet we're eating.
Okay.
Zeeke, the subtitle of your book is six simple rules for long and healthy life.
I'll go through them.
Number one, don't be a schmuck.
Number two, talk to people.
Three, expand your mind.
Four, eat your ice cream.
Five, move it.
And six, sleep like a baby.
There's also really seven.
The conclusion is called be a bench.
So let's start chapter one.
Don't be a schmuck.
What are some common schmuck behaviors?
And why do people do them?
Do you think is it that they lack willpower?
Is it that they don't know better?
Is it pure pressure, et cetera?
Well, smoking is a very good case of where it is a schmuck move as is vaping.
And it's not because people don't know.
I mean, actually, smokers know the dangers of smoking better than the rest of us.
Partially, that's an addictive element.
And partially, it's a social system until recently.
Society was actually pushing people to smoke through advertising, through pricing, and
the social acceptability of smoking.
We've changed that.
What we haven't changed is we really need to increase the taxes on tobacco.
We haven't increased them since 2009 at the federal level.
And I think that's very important.
But we switched to vaping.
Now vaping has some advantages.
It appears to be less dangerous than smoking.
I said it appears because we've only had about 20 years of vaping and who knows what's
going to happen.
But there's no free lunch.
Vaping still has adverse side effects on people.
I think there's other items I like to mention, climbing Mount Everest.
I can go as a tourist.
I can pay $100,000 in doing it, and it turns out it's incredibly dangerous.
I mean, all commerce, including the expert climbers, the chance of dying on Mount Everest
is 1 in 100.
And if you're over 59, it's 1 in 25.
That is a total schmuck move.
Who would take a 1 in 100 chance for what, bragging rights?
Just seems crazy to me.
Also, the actual most dangerous job I've seen is being president.
We've had 45 people president, and four of them have been successfully shot and killed.
And eight of them had been shot at.
They may not have died.
But that just seems like a very, very high number of attempts on people despite great secret
service protection.
Okay.
Note to myself.
Don't run for president.
I'm not going to become president.
Yep.
Okay.
Chapter two is called talk to people, mostly advice in this chapter, it seems comes from
your father, which I very much enjoyed reading about.
Chapter three is called expand your mind.
Here's something you wrote, accumulating a reserve of brain function can protect from
the inevitable losses that occur with aging.
Is that real?
Is there a reserve of brain function?
And if so, what's the evidence for that?
The evidence is that people who've gotten more education and therefore more brain connections
have the same rate of decline, but because I start from a higher plateau, it's noticeable
as a cognitive decline and loss of function much later in life.
There is very good evidence on that.
Just think about how the brain works.
The main way that you get cognitive being cognitively intact is you have a lot more connections
between your neurons, it's called brain plasticity, your ability to make more neuronal connections.
And then as you age, you lose those neuronal connections and you lose cognitive function.
What we're trying to do is push the date at which we lose cognitive function that it becomes
noticeable out as far as possible.
There are some people who are remarkable, who are productive and creative into their 70s
and 80s.
Ben Franklin is my quintessential example.
Is your spirit animal?
Can we just say?
Yes.
Well, I have a whole course on him.
I know, and you're writing a Franklin book as well, correct, or plan to?
I plan to.
Yes.
Are there not enough Ben Franklin books in the world?
There's very long and I want to target younger belts because I think they don't emphasize
him as a role model for living.
The chances he took, the initiative he took, the constant creativity he engaged in, where
everything in the world was, okay, how does that work?
And him spending a lot of time trying to puzzle things way out of his expertise.
He once walked through a hospital and noticed a lot of people and they had these common
symptoms.
He says, you know what?
They all have in common.
He said to the doctor, they all work with lead.
It took us another 150, 200 years to figure that out as doctors.
It seems as though you want to hold him up as a role model for a variety of things, but
one of them is aging, of being productive as you age, and also continuing to learn.
In chapter three of your new book, you advise against retiring generally, but I wanted to
ask you, you, Zeke, plainly like, maybe love and are plainly energized by your work.
I'm happy to say that I am lucky enough to feel the same, but many, many, many people don't
like their work and they don't get that same kind of joy or energy out of it.
So for people listening to this and they hear Zeke manual say, don't retire, don't
ever retire.
And they say, well, I do want to retire from what I do.
How do you think about that next phase where you're retiring from your vocation or your
occupation, but how do you set off on a new chapter that's as energizing and productive
as the one that you want?
We do have data that countries where retirement is younger, people have a faster cognitive
decline.
There's a sociability with work.
There's a schedule and expectations of other people and you.
There's cognitive challenges of how to solve problems at work, and there are new things
that you have to do.
When you think about retiring, you should think about all four of those elements.
How are you going to replace them?
What are you going to do for the sociability?
How are you going to actually interact with people?
One of the things I suggest to people is I understand if you want to retire if your
job is in fulfilling, all right, then how are you going to volunteer and how are you going
to do things that give you a schedule, make you interact with other people, make you learn
new skills and make you solve problems.
One of the things we know from data that a colleague of mine has collected is when people
retire, the thing that goes up the most is TV watching.
That is not a good place to be.
That is not going to stimulate you cognitively.
I think if you want to retire from an occupation, you got to figure out the volunteer activities
or the social engagement that you're going to have as you age.
Unfortunately, not a lot of people spend a lot of time consciously thinking about what
that's going to look like.
When it comes to your advice on expanding your mind, I'm wondering where you stand on
drugs.
Cannabis is ebbing and flowing in legalization.
It seems like in the last month or so, the Trump administration is moving back toward more
legalization when there was looking like there might be a little bit less.
Mushroom uses up, ketamine uses up.
What's your position generally on mind expanding or mind changing drugs or other methodologies?
Maybe he'll tell me about meditation.
I don't know.
On drugs and in particular on pot legalization, I think this is one of the three great social
experiments we've had without a control group and that is probably in the end not going
to be good.
Cell phones, social media and pot.
We know that we have a lot of cannabis use disorder about a third of people who use cannabis,
can control their use about 10% of people are actually addicted to cannabis.
They can't get off.
It has the same kind of pathways as other addictive drugs.
I think there might be, and again, I'm not a user.
There might be some conditions.
It might be better than alcohol, but that still doesn't make it good.
Silicibin is a completely different issue and I've done some research on it.
So I should declare that conflict of interest.
Did that research include swallowing?
No.
I've had people advocate.
You ought to try it.
I said no.
That's not Zika manual.
No, that the world could tolerate me.
Maybe you become more tolerable.
You considered that possibility?
Only if I became more boring.
Okay.
You don't want to remove your edge.
No, I like my edge, actually.
There are people who aren't depressed.
People who have PTSD, we've done some research on what happens when you've got depressed
cancer patients, give them a dose of psilocybin.
First of all, you see the depression go away in very short order within a week much faster
than if they took a project or some other drug, and we've done some research to say it
can last 18, 24 months, not for all of that, but for many of them, and that's with one
dose.
So I think that can be very therapeutic in precisely a very hard problem to handle, which
is resistant depression.
I think in five years, psilocybin is going to be standard of care for probably depression
and PTSD.
And how would you describe the plausible biological mechanism of psilocybin and depression?
I've heard a variety of things from people who know quite a bit about this.
Some say that PTSD is a failure of the forgetting mechanism that you're ruminating on an experience.
Let's call it again and again.
I don't know what psilocybin or other drugs may do to interrupt that trajectory or if it's
something else.
Why do you think it works if it does work?
I'm not an expert on its biological nature, but one of the things we do know is look, that
it works on the brain suggests that there's a receptor on the brain, which is being activated
by psilocybin that is supposed to do something in the brain positively.
It was conserved through evolution.
This rewiring of the brain does seem to be something where people attached to something
that happened in their past and can let go of it.
Forgetting certain things, really important for human beings, we know that people who have
these photographic memories and can't forget are actually quite paralyzed.
One of the things my kids say to me is that I don't stay mad at people unless they lie
to me.
They stab me in the back after telling me nice things.
Then I get pissed off permanently.
But I'm actually one of these people who, you know, if you offend me, you say something
nasty to my face, I don't get permanently pissed off at you.
And I think it's an important attribute because it allows you to move on with people.
It's an important lubricant to social interaction.
We're all going to offend people.
And sometimes I'm a big offender and I sometimes say things that hurt people.
Even what I don't mean to, we have to learn how to forgive.
That's a really important thing to think about.
I love that you point that out.
I agree.
I think that's really important.
Also, however, find it interesting that while there are some people who offend without
even meaning to, which you just described yourself as one of those people, there are a lot
of other people who work really hard on never offending anyone.
And those people I find so boring that I feel I need drugs to be around them.
Well, it's not just boring.
I find them unreliable because they're not telling you the truth.
One of the things I always tell the people who work for me, they're junior and often
somewhat intimidated, unfortunately, around me.
I say, listen, tell it to me in part because I have two brothers and they have said things
to me.
You can't even approach how severe and painful that can be because they know exactly what
pushes my buttons.
So don't worry.
And by the way, I won't hold it against you.
I much prefer when people tell me the truth.
Then I learn something.
When people are lying to me about how wonderful everything is, I don't know how to fix things.
I don't know how to change my behavior.
I don't know how to change the world.
I prefer the truth even when it's painful because it's always something I can learn from.
I have a thick skin because of my two brothers.
We should say your family system is a little anomalous.
Your brothers are their edge if we're going to use that word is on a scale of one to ten.
It's maybe thirty from a manual and arie men or right?
I mean, you've been well trained to deal with things like that.
Yes, but I do think actually having a thick skin is an important element.
Not to be offended by everything.
One of the things my father and I think taught us is, look, some people may not respond
to you positively.
Don't take it personally.
Just understand they may not be having a good day and move on.
I do that a lot.
I'm not perfect at it.
And I still can be socially awkward about introducing myself to people.
But it's a great attribute, I think, because it allows you to actually survive in a lot
of circumstances that other people get paralyzed by.
Coming up after the break, Zeke a manual on Trump administration health care policy
and when to give technology a rest.
I'm Stephen Dubner.
This is Frekenomics Radio.
We'll be right back.
Last week on the show, we spoke with Marty McCary, Commissioner of the Food and Drug Administration,
and part of a Trump administration whose health and wellness policies have inflamed many
people, including the vast majority of the political left.
Zeke a manual has spent a lot of time in and around the political left, including the
Obama and Biden administrations, but he has also worked with the Trump administration
during Trump's first term.
I asked a manual what he thinks of the current Trump administration's health policy.
Everything is for sh** in Washington, but the guy's running Medicare and Medicaid.
As I did not predict it, he has actually done a very good job of attracting the right
people and doing the right thing.
A manual here is talking about Mehmet Oz.
He is running CMS, the Center for Medicare and Medicaid Services, way better than Biden
did.
Biden's person came in and went and I asked everyone, I said, so what did they do?
And these guys, they're actually doing good stuff.
Why were you so skeptical of Mehmet?
Because I thought he was willing to prostitute himself and say stupid stuff to make a lot
of money on TV.
And I didn't know whether that's why RFK Jr. brought him in that he would do his bidding.
And he hasn't.
He really has said, how are we going to make healthcare better for people?
And the other thing which I greatly actually appreciate, they don't care.
And I wrote this about exactly a year ago.
I said, these guys are coming in.
The best thing that could happen is that they don't give a **** what the interest groups,
what the AMA says, what the hospital association.
And that's actually really important because you can't reform it if you constantly trying
to placate everyone.
And I'm impressed.
I'm very impressed.
These guys are actually doing good.
Name a couple of things that they've done.
So they've initiated some prior authorization that is going to tamp down on some abuses.
They have initiated new programs aimed at getting better management of chronic illness
and using apps and technology that we know work to do it.
There's just a recent report about AI getting people who have diabetes on the right dose
of insulin in 15 days as opposed to doctors doing it, taking more than 56 days.
Okay, that's really valuable.
And that also means the doctors can focus on other things and the AI can handle the patient
through Alexa.
And I'm like, that's fabulous.
Let's do more of it.
And they are on that path to doing more of it.
They've launched a program called Access, which is very likely to go exactly in that direction.
So if you roll up, let's say Robert F. Kennedy Jr. and Marty McCarry at FDA and Memadaz
at CMS and roll them up into one class the first year of the second Trump administration's
health and science policy.
What's a letter grade?
D.
D.
Oh, that's still pretty poor.
But you have to average an A at CMS, but an F at everything else.
RFK Jr. is going to make a lot of people die through just the vaccine thing alone.
He hasn't done anything really on the food system.
I mean, taking dies out is not going to save a single life.
He's undercut the entire structure and scientific review process that we have.
They have the focus on chronic illness, very good, but they haven't actually done that
much on it.
I wonder whether you try to be apolitical or not really in your book.
You give a hard time to Casey Means, Trump's nominee for Surgeon General.
You ridicule her health and wellness obsessions, which you seem to think are pretty flaky.
And I get that, but a couple elections ago, one of the Democrats running for president
was the self-help guru, Marianne Williamson.
So I wonder when you are strongly affiliated with one party, the way you have been,
whether it's just not possible to consider the upsides of your opponents arguments and
the downsides of your allies, and whether you become too partisan, a thinker, even in
the health and wellness arena, that's not true for me.
My goal is to fix the American health care system for the American people.
That means five things, getting universal coverage, making costs reasonable for everyone,
having consistent high quality, diminishing disparities like rural urban disparities,
black, white disparities, and having people fully satisfied.
You can't do those things without bipartisanship.
That's the first thing.
The second thing is early on, I talked to President Trump in 2016, and November in December
2016, trying to talk to him about how I thought he could improve the American health care
system.
And I was pushing him to focus really on drug prices.
So we had a number of meetings.
I was happy to work with them.
Then when COVID hit, I wrote him a memo about how to begin approaching COVID.
Joe Biden called me and said, we'd like you to help, and I'm like, anyone who wants
to make an improvement in the American health care and address this pandemic, I'm open
to it.
I told Biden I was working with Trump, and he said, fine, we don't care.
But Trump, that was not the same attitude.
And he got upset and cut off discussions.
Did you try again with Trump, too, in 2024?
We are regularly working with Trump, too, about trying to address American health care problems.
Who's the we?
Zeke.
Me, me and my team.
So we're trying to work on, you know, focusing on hypertension, we're trying to work
on this upcoating problem and getting Medicare to do a better job of risk adjusting.
We've actually developed a better risk adjustment model than they used now and trying to get
them to adopt it.
I am, I don't know whether non-partisan, bipartisan, there is a big problem, and we need
to solve the problem, and this problem isn't going to be solved by one ideological view.
You have to work and keep working at it.
There are people on the Republican side who I've learned a lot from, there are people
on the Democratic side who I've learned a lot from, there are people on the Republican
side who I think have wacky ideas about how to fix the system that aren't going to work
in the same things through on the Democratic side.
I am willing to work with anyone to help solve this problem in part because we are now
at 18% of GDP.
That's one out of every six dollars that we spend.
It's a major cause of the unaffordability problem for every American.
If we could bring our healthcare spending down to 13%, that's a 5%age point drop, 5%
in a 30 trillion dollar economy, 1.5 trillion dollars, that's $5,000 for every American.
Just imagine what would happen if we could bring our spending down to the top of Europe.
A family of four would suddenly have $20,000 more to spend on everything else they need
in life.
It would radically change how Americans live.
Now I don't know that I could in my lifetime get us down 5%age points of GDP, but we should
be able to get down 2% or 3%age points of GDP, and even that is a huge amount of money
for people.
Last time we focused on GLP1 drugs, their efficacy, access to them, affordability, potential
downsides, can you just give me a quick update?
What have you learned about the GLP1 drugs in the last year?
I do see, for instance, that Novo Nordisk, the Danish multinational farmer firm recently
won approval to sell wagovie in pill form in the U.S., that will be the first GLP1 that
I'm aware of in pill form.
So there's obviously a lot of momentum in that area.
What's the state of the union with GLP1s in your mind?
In the last year, we have learned more and more about the positive benefits, and we've
cleared up suggestions that they don't have certain effects like reducing the risk of
dementia.
People were very hot on that, at least in the first set of studies does not appear to
be the case.
One of the biggest home runs, I think, is they have enormous effect very quickly in terms
of reducing cardiac risk factors and cardiac mortality.
That's amazing.
20% reduction in a year, that's pretty amazing results.
What's the plausible biological mechanism for that?
You're reducing weight, you're reducing the cardiac risk factors for causing plaque.
You end up reducing blood pressure as well, and that also reduces renal disease and kidney
failure risk.
I think the second thing that has become quite clear is no one predicted when they began
researching GLP1s decades ago that it would cross the blood-brain barrier, and it would
affect the central nervous system and, in fact, affect the reward system, and now we know
that it somehow does all that, so there's less positive reward from food, but also alcohol,
tobacco, drugs.
That, I think, is going to turn out to be an amazing result that we're only going to learn
a lot more about how you can use it to regulate these other addictions.
It gives more plausibility also to some element that food can be addictive as well.
I'll just tell you, I have a very dear friend from college, and I suggested he go on a GLP1.
He went on a GLP1, and the next day he called me up and said, my relationship to food is
very different.
I no longer have this battle with it, and then I talked to him just the other day and he
said, well, I've had to go off the GLP1s because we had a change in insurance, and I can't
afford it, $1,200 a month that just can't afford it.
The problem is we have this miracle, and people who need it and can benefit from it aren't
able to get it because of the cost.
We need to be more creative in our society when we have these really big breakthroughs for
a large number of people of getting it at a reduced rate.
Me and my group have been advocating for thinking about subscription models of GLP1s,
because we can lower the cost, the marginal cost of production is very small, and increase
the number of people by maybe even an order of magnitude.
The pill form I've read, and I would assume anyway, is going to be much, much cheaper,
correct?
I'm reading wagovie monthly pill form will be about $150 a month for what they call
the starting dose versus about $1,350 a month.
That tenfold difference is not production costs.
It's profit.
I think no more Nordisk has been losing market share and needs to gain market share.
This is an easy way, but I think that's the kind of, if we had under $100, so we're
talking maybe $1,000 per person per year kind of if we got to that level, it would be
a home run.
It seems like we're heading in that direction, yes.
Yes, we're heading in that direction, and I think within ten years we're going to have
a lot more options with a lot fewer side effects that are more targeted, and the price will
come down.
I think that will be fantastic for American society.
Let me just say that's not the way to solve our obesity problem in America.
Let's talk about that for a moment, because all these things you're saying about GLP
ones are phenomenally good and or promising.
On the other hand, I hate to be the skeptic, and I hate to bring the economists into the
conversation where they may not be welcome.
I don't know, but economists, as I'm sure you know, have this phrase, moral hazard to
describe a situation like this where when you lower the risk or the cost of potentially
hazardous behavior, like overeating, or eating a lot of unhealthy food, that you maybe
encourage people to do more of the same, because you're giving them a kind of safety belt.
How do you feel about that?
In other words, you've just written a book promoting sensible good nutrition, diet, sleep,
et cetera, et cetera, et cetera, but if there are pharmaceutical solutions that obviate
the need to change behaviors, where do you fall on that?
Well, I totally agree with the economists.
Not on the moral hazard problem, and I'll explain why.
But on the idea that GLP ones are not the solution to the obesity epidemic, although we
should acknowledge that in the last year, the percent of adults who have been obese
has dropped 2%, and we've not had to drop in decades in the number of American adults
who are obese.
So something is happening with GLP ones.
So here's one important way in which I think actually having the GLP ones are not going
to lead to moral hazard, but actually might change the psychology of people.
One of the things that happens, I think, when people gain weight is they become despondent
about themselves, about life, about the future.
And I think, if you now recognize, well, I lost 20% of my body weight, my body image
is better.
I now see the future differently.
I have hope.
I have hope that I can control things.
I have hope that I can actually change my life.
I'm going to invest in my life differently.
I might adopt exactly what we want them to do, exercise, better nutrition, better sleep.
You know, the sleep apnea will go down.
All of these things suddenly become different and the valence, my ability to see hope in
the future.
And therefore, investing the future is going to increase.
You need to figure out more about how to appropriately use GLP ones.
You might be able to get people to drop 20% of their weight inside of a year, then go
on a much smaller dose of GLP ones for the long term.
We also don't know how giving them simultaneously diet and nutrition advice, as well as exercise,
coaching, how those will intersect.
I suspect they're actually going to be synergistic for all the reasons I say.
So what's interesting to me, Zeke, is that you write about this age we're in, this
wellness industrial complex.
You describe it as a tsunami of information that's coming to us, some of it too complex,
some too simple.
But one big point you make is that most of the behaviors that you want people to follow,
which is eating sensible food, getting sensible exercise, sleeping well, et cetera, et cetera.
You can't make a profit by prescribing that.
And that runs up against not just the wellness industrial complex, but really the healthcare
system where, as you know, better than any of us, many physicians, the way their incentives
are laid out is to treat illness and not to encourage wellness.
So if you take a step way back, do you see any philosophical or theological adjustments
that might be worth making?
Oh, absolutely.
A lot of people think, well, wellness is an individual thing, but that's wrong.
And we all know it because the whole issue with ultra-processed foods is we've got a whole
food system that is incentivizing through food subsidies to corn and soybeans and wheat
and rice, as well as many other aspects that make ultra-processed foods cheaper.
We don't subsidize fruits and vegetables.
We don't subsidize other very nutritious elements.
That's one area.
The other area is we have a whole system now that is making us lonely.
We've got cell phones and social media, video games.
So people are no longer interacting and they're no longer talking to people.
I prohibit cell phones in my classroom as well as computers.
You come into the classroom and it's a lot louder than it used to be because people
are actually talking to each other apparently in New York where they've bell to bell prohibited
cell phones, what they've noticed is that actually the volume's gone up and that's
a positive because you've got more students talking to each other.
I have noticed that the whole cohort of my students, they're sort of socially awkward
because they don't know how to talk to each other.
They don't know how to navigate conflict or disagreement between themselves.
That is a very bad thing.
We've created lots of social barriers to actually wellness, not just in the health system
and believe me, I could go on for the next two, three, four days talking about the problems
of the healthcare system and the promotion of wellness.
But we also have other social systems like social media, like the way people actually
earn their living as well as the food system, the exercise system that make it hard for
people to live a healthy life.
There is this age-old wisdom and part of our issue is we have to constantly rediscover
it as you point out and I don't think that's new, you know, what's the renaissance?
Well they rediscovered the verities of the ancient Greeks and Romans, okay?
Wellness is about biology and the core elements up were really social beings, Aristotle knew
this, right?
Two books of his famous Nika McKee and Ethics are devoted to friendship and how important
friendship is both for virtue but also for a good life.
Hypocrity understood diet and exercise.
It strikes me that one prescription that I'm not hearing from you or anyone is that people
need to read again.
When you talk to college professors, they say that even at good universities, they can't
get students to really do any real reading, even a hundred pages of a book, forget about
the whole book.
Have we just given up on that notion, do you think?
I hope not and I was just bitching about that problem of reading yesterday.
It's very hard to get students to read and they complain no matter how short your reading
lists are and I think it's super important and we've lost that art and that also means
we've lost part of the art of critical thinking to read something we don't agree with or
to follow a detailed argument that's a little more complex and one of the things I bemoan
over and over is how simplistic the lack of nuance in social media posts.
How can it be nuance and I was terribly against social media for that exact reason.
You can't have a prolonged discussion.
I have an avocational interest in American history and you think about how long the debates
were of the Lincoln Douglas debates and then you're like, oh, in American presidential debates
now, there are two minutes on each side and then a 30 second rebuttal.
They're not 45 minutes speeches that are subtle and have a long development of argument.
I mean, this is maybe polyannish and I'm not even sure it's desirable.
But do you see a way to get back to, I'm not talking about Lincoln Douglas debates necessarily,
but do you see a way to get back to a longer attention span, more attention to detail,
more nuance, et cetera, et cetera?
Obviously, there is a layer of society that still engages in all that stuff and I would
argue that probably many people who listed this program are part of that layer.
But having a thin layer at the top is not very good.
I think do you have any thoughts for making that layer deeper?
Well, I do have thoughts and I think one of the reasons that a electronics Sabbath is
a good idea.
One day a week where you just shut down the computer, you shut down the phone, is good,
is that can be a day where you read.
For the last two years, I have pledged my New Year's resolutions to have a full electronics
Sabbath.
I have yet to reach that.
I'm about 70% of the way there.
I hope 2026 is the year I can actually fully realize it.
But I think that's an important step in the right direction for us, a day when we're not
distracted.
And what this really is, Stephen, is it's about time allocation and it's about prioritizing
deeper thinking and deeper reflection, including time with ideas that you don't necessarily
share to understand why someone might advocate that and to give them the most charitable
reading you can so that you can think through, well, you know, maybe I'll change my life.
Maybe this is a perspective I need to adopt.
Moving up after the break, has Zika Manuel figured out the meaning of life?
I'm Stephen Dubner.
This is Freakonomics Radio, we'll be right back.
Let's talk about chapter four, Eat Your Ice Cream, which is also the title of the book.
And I find that chapter four is kind of the meat of this book because it is about what
to consume and not consume and how to behave and not behave and so on.
You describe a sort of vicious circle where people trying to do better with their nutrition
and health, exercise and so on, they often get so stressed out about how to do it that
it adds more stress to their lives and that can have a negative impact on their health.
So can you just walk us through that vicious circle and how to get out of it?
First of all, we have to remember wellness is for decades, it's not for a moment.
Wellness is going to be your lifestyle, how you live and the habits you adopt on a daily
basis.
They have to be things that don't require willpower because if they require willpower,
you're going to exhaust them and you're not going to follow through.
So that's the first thing.
The second thing is there are a lot of things we're doing that are anti-wellness and one
of the interesting things about human beings that I think doesn't get enough play is we're
an additive species.
When we confront the problem or a puzzle or something, we tend to solve it by adding things.
One of the important things I think about wellness is we have to actually take away the bad
stuff we're doing and we don't do enough of that.
Look, there are a lot of negative things in our diet.
The top one is sugary beverages, sodas, because they are 140 calories per 12 ounce can,
10 teaspoons of sugar with absolutely no nutritional value.
Don't do them, they're not good for you and the good news in America is if we need good
news on nutrition is we're actually decreasing our soda consumption.
The second is snacking has increased to 500 calories a day over the last 30 years.
We've got to bring it way down, I'm not telling you no snacks, but bring it way down.
Those two things alone will actually improve things and then one positive, which is eat
more fermented food, eat more fiber.
Those are the two big things we're lacking in our diets on a regular basis.
You will be a lot healthier just those things.
Take away two items and add two items.
Let's talk for a minute about the gut microbiome, which is something that for reasons I can't
explain I've been interested in for a long time.
Also, it's one of those topics that I feel we've been promised a lot more good research
over the past 10, 15 years than we've actually gotten.
I know there are many, many, many people working on it, but it seems as though the microbiome
is a much more important driver of overall health than people a hundred years ago may
have imagined.
I don't know, for all I know, maybe they were way ahead of us then.
Can you just talk for a minute about the state of gut microbiome research and what you think
will be learning over the next 10 or 15 years, it might be really useful?
Oh, absolutely.
I totally agree with you for most of the 20th century, the ideas, bacteria, bad, they
cause illness, they kill you and antibiotics, good, and then what we've learned over the
last 30 or 40 years is that way over simplified those bacteria, they're really there, they're
good.
We've grown up with them and we've adapted to them.
Just think about it from an evolutionary standpoint.
We have more bacteria in our gut than we have cells in the rest of our body.
They got to be there for a reason.
That's very important.
We also know that the diversity of microbiome is a very important sign.
Exactly the function of each species were beginning to elucidate this.
All of us are impatient, it was 55 years ago that Richard Nixon created the war on cancer.
Now we've gotten all these treatments and cures, frankly, it took 55 years because cancer
is complicated.
The microbiome and its effect on biology, the same thing, it's going to take us probably
another 20 or 30 years to really dissect out everything in the circuits and really make
a lot of advances.
Nonetheless, we do know just basic principles.
Diversity is good, the microbiome needs a lot of bacteria, but it also needs a lot of fiber
and different kinds of fiber, not just the fiber supplements you get so that the bacteria
can grow.
They protect the lining.
It's probably related and here I'm going a little out on thin ice, probably related
to the rise in things like colon cancer and other illnesses.
Especially among young people, I remember last time we spoke, you were pretty surprised
and shaken by the rise in colon cancer among people in their even 20s and 30s, yeah?
Yes, and I've had a lot of friends who've been diagnosed and unfortunately died from colon
cancer in their 30s and young 40s.
When you say that the microbiome is a site of interest there, what do you think is happening?
Do you think this has to do with ultra-processed foods?
Do you think it has to do with antibiotic, I don't know where to lead you, so I'll let
you lead.
I do think ultra-processed foods and the decreasing diversity, I also think probably pesticides
that we've consumed and are on everything also decrease the diversity of our microbiome
and the right kind of bacteria that protect the lining of the colon decreasing.
And where do those right kind of bacteria primarily come from?
Each are all the things that we are supposed to eat.
So this is fermented foods, yogurts, etc.
And fiber so that they can grow in the gut and they can outcompete the other bacteria
that we have.
This is where I get nervous.
About 60% of calories among adults and children are ultra-processed foods.
That is not good.
We know that decreases the microbiome diversity, diet sodas decrease the microbiome diversity.
Only 7% of the American population consumes enough fiber.
That is horrible.
We really need more fruits and vegetables as a regular part of our diet.
I think this emphasis on protein is overdone and the emphasis on fiber is underdone and
we need to shift that.
I do think, Stephen, one of the things we are going to learn is which bacteria are really
important and also what the different bacteria do, the impact on our cognitive function, our
cardiovascular function.
I think we are just at the start of it.
We do now know things like fecal transplants can be effective in treating diseases like
C difficile which are caused by over antibiotic use are going to be really, really important.
The other flip side and I think it is important for the listeners not to forget this is, we
unfortunately have in our food system, we treat a lot of animals with antibiotics and
that is probably a bad thing because of antibiotic resistance and also maybe some of those
bacteria are not so bad for us to consume.
We do know in some cases some of the bacteria are really bad, raw milk, not a good idea,
but in many other cases I think treating chickens and beef and other animals with antibiotics
is a bad idea and not good for our food system.
This goes back to the issue we were talking about before.
Doing well and having wellness, it is not just what I do.
It is also what the system does and unfortunately the American system is focused more on making
profits for this part of the economy and externalizing the costs on the rest of society.
What you are describing is what some people might call a wicked problem, not just people
from Boston but researchers like to describe a wicked problem is one that is entrenched
and has a lot of different players in it who have incentives to maintain their
incomeancy and so on.
Any solution that I would think that you would like whether it is in the health care system
and the food system and so on is inevitably a political solution.
Is it not?
I agree with you.
We have to change the food subsidy system we have in this country.
Can we change it overnight?
Absolutely not.
We have farmers who have grown up with the food subsidy who have created their production
and we have to slowly shift.
Can we do that?
Yes.
We have learned we can do that with tobacco.
We have learned we can do that with coal and we have to shift and give them alternatives.
I think that is going to be in every American's interest.
There are a lot of societies out there where only 20% of the calories are from ultra-process
foods.
That is where we need to be.
Let's talk about chapter 5 for a moment.
Move it.
This chapter I liked a lot.
We did an episode once called What's the best exercise and the answer was the best
exercise is whichever one you will stick with.
I thought of that because when you are writing about exercise and the benefits and so on,
you are really writing about habit formation.
You mentioned earlier in this conversation willpower and how you can't really rely on
that.
What about that overlap between exercise and habit formation and how you would advise
someone who wants to be more active, wants to be more regular in their activity but as
a hard time getting there?
You have to have the attitude.
I want to start this.
That is the first thing.
Initiation.
I am going to start.
The second thing is you have to actually set a date, set a time and make it at least three
or four times a week.
You are going to do something.
I often recommend doing it with another person because they keep you honest and they too
want to do it and you are sort of playing off each other.
The really important thing about exercise is the repetition.
The best data that I have found is four times a week for six weeks really gets you to
a stage where it has become a habit and you are more likely to continue it to 12 weeks.
We don't have very long term outcomes.
The important thing there, I think, is by the time you have gone six weeks, you have
built it into a routine and that is the critical element, the repetition.
The thing I recommend to people is, and this is what I do, is vigorous activity.
You need 75 minutes.
That is 10 minutes a day.
I don't do 10 minutes a day.
I do 20 minute chunks.
In the winter, I get on a stationary bicycle three times a week for 20 minutes and I do
a lot of other activity.
Is your degree of difficulty on that bike?
I do a Peloton exercise and I end up sweating in my heart rate, it has to go over about 110.
That's not crazy.
110?
It's not crazy.
Almost everyone can find 20 minutes or with a shower and whatever else, 30, 35 minutes
a day, three times a week.
That's not that crazy, a time period.
Some weeks, like this week, the holiday week, I am not going to exercise.
I'm away from home, I will continue to do my yoga, but I'm not going to get out on
the bicycle.
All right.
Then I'll go back home where I have all the setup and I'll continue it.
Am I going to become suddenly unhealthy?
No.
You know, I'll get back on to it.
Let's talk about chapter six for a minute, sleep like a baby.
So I'm already a sleep advocate.
I love to sleep.
I'm like Olympic level sleeper, everyone in my family is very jealous.
What's your secret, Steven?
Come on.
Here's the problem.
It's just natural.
It comes to me.
I feel a little bit guilty about it because I have a lot of friends and family who really
do have a hard time sleeping.
And therefore, they reach out to what strike me as often absurd aids for sleeping.
And you're not a fan of some of the absurd sleep aids as well or sleep advice, I guess.
So why don't you give me the do's and don'ts of the Z-commanuel sleeping program?
First of all, this is one where everyone has to be forgiving of themselves.
Every other wellness behavior you can will yourself to do.
You can will yourself exercise, you can will yourself to eat well, you cannot will yourself
to sleep.
You get in bad and you're willing yourself to go to sleep.
It will not happen.
We all mold that.
Second, we are all prone to quick fixes.
That's the American way.
We reach for the melatonin or we reach for the magnesium or whatever our pill of choices,
you know, the American Academy of Sleep Medicine, no, they do not work, do not do them.
It's not the approach to take.
There are two things we can do.
One is we can set the bed and set the room up, make it dark, make it cool, tape over
those lights or get those things out, put the phone in a different room, get in bed, read
an actual book, not on a computer screen, and then go to sleep.
No guarantees that way, right?
And then if you're still having problems, after you've done that for a while, cognitive
behavioral therapy for insomnia is the most effective treatment.
You don't seem to put a lot of stock in apps that track your sleep, why is that?
I get up in the morning, you get up in the morning, you feel well or you don't feel
well.
Let's say the app tells you something different, well, you're going to believe the app
more than your body?
No, your body is the ground truth.
Are you feeling like you can concentrate, like you've got the energy for the day?
If you don't, I don't care what the app says.
If it's anxiety provoking, which I think most of the sleep apps are, it's unclear what
advantage you're getting.
It's not like wearing an aura ring or an apple watch that they're actually going to make
you sleep.
They're not solving your problem, they're not therapeutic, they're giving you data and
sometimes that data just makes you more anxious and that data is not more valuable than what
your body is telling you.
So a lot of the advice out there around health and wellness or the wellness industrial
complexes we're calling it has to do with things you shouldn't do.
Some you should, but a lot that you shouldn't.
One thing that I just liked about your book was that you focused on some of the dues beyond
just the foods that are good for you and the exercise that is good for you, but also the
notion of joy and celebration and setting out to actively celebrate yourself for others
and so on.
How about how to make that more of a routine for more people?
We're on this earth for 75, 85, 90 years.
That's it.
You can practice a lot of self-denial.
You can practice a lot of anxiety over getting everything right or you can live a meaningful
life where meaningful is mostly I find.
It's about other people.
It's about doing good in the world.
It's about connecting to people.
But I have a dinner party and I have people over and we're having a really good conversation.
That's great.
My joy is up.
It's also good in the long term because social ability is good and third, it's virtuous
because the other people are gaining that social ability, that good conversation.
We're all in it together and we're all actually making wellness part of our everyday life.
It's like a trifecta.
It's a wellness trifecta.
It's good today.
It's good for tomorrow and it's good for the other people.
What could be better in life?
You quote the late British chief Rabbi Jonathan Sachs who wrote,
we defeat death not by living forever, which as we know is impossible, but by living by
values that live forever, your bookseek is mostly about personal behavior and not values
per se, but my sense is that the values are always just underneath the surface.
I'm wondering what you have to say about that.
If I asked you to synthesize or summarize Zeke Manual's values to live by beyond the eating,
the exercise, et cetera, et cetera, what would that be?
You're 100% right and I don't think they're that much beneath the surface.
To go back and quote Ben Franklin, his great thing is be useful and by you be useful, he'd
meant how are you making the world better?
One of the things I think my parents instilled in me and my brothers and now you're going
to make me cry when I think about my parents is, look, you are privileged.
You came into this great world.
You came into it at a great moment and the real challenge for you is how are you going
to make it better for people who aren't as privileged as you are and how are you going
to make it a better place going forward?
I think I've dedicated my life to trying to make the world better, whether it's by improving
the healthcare system, by mentoring kids and putting them on the right way.
There are so many ways we can make the world better in our daily life, cheering people
up, just growing things.
Ben Franklin challenges us, be useful.
How are you being useful?
How are you making the world better?
Is the most important thing we can commit ourselves to and it'll give us joy because that's
part of having a meaningful life and if there's anything that makes our life better,
it's having meaning in it.
Zeke, I enjoy every conversation with you, but I think this is my favorite.
So thanks.
I'm honored, Steve, and you are the best interviewer.
Thank you so much.
Let me just say for the record, I'm pretty sure I am not the best interviewer.
So if Zeke Manual is going to get that wrong, maybe we should just discount everything
he said today, I'll let you be the judge.
Again, his new book is called Eat Your Ice Cream, six simple rules for a long and healthy
life.
Let us know what you thought.
Our email is radio at Freakonomics.com, coming up next time on the final installment of
the Freakonomics Radio Guide to Getting Better.
Are we about to take a giant leap forward in medicine?
It's happening in aid emergency departments in the greater New York area.
They're automatically being screened by the AI model for heart disease.
As we all know, the healthcare system could use some serious disruption.
There are a lot of reasons that we are pretty static and we like technology, but we like
it in very, very specific ways.
So how much and in what ways will AI remake medicine?
It's next time on the show, until then, take care of yourself.
And if you can, someone else too.
