The podcast critically examines Bulletproof Coffee and Dave Asprey’s biohacking lifestyle, exposing a pattern of misleading health claims and pseudoscientific marketing. While the idea of coffee with butter or MCT oil is simple, the health benefits are not supported by strong evidence—research is minimal, often anecdotal, and frequently cherry-picked. The podcast highlights that claims about enhanced cognition, fasting benefits, and anti-mold properties are unfounded or based on flawed logic. Asprey’s credentials are exaggerated, with fabricated scientific lineage and selective citations, including studies with tiny sample sizes or from discredited sources. His diet is presented as cutting-edge but is actually a collection of outdated wellness trends, like keto and intermittent fasting, wrapped in overly complex rules and jargon. The podcast also notes the absurdity of elements like bringing butter and MCT oil to restaurants, suggesting the lifestyle is more about marketing and personal control than health. Ultimately, the show concludes that Bulletproof Coffee and the broader diet are not scientifically valid, are expensive, and serve more as a self-reinforcing narrative of elite control over one’s body than as a legitimate health solution. The takeaway is clear: the claims are not backed by science, and the audience is encouraged to question such "miracle" diets and recognize the gap between marketing and medical evidence.
it's also been uh clipping a little bit lately because you've i feel on my end i feel like you've
been doing more bellowing than usual you're like six percent more bellowing that sounds like me
maybe turn the gain down like three percent or something yeah yeah hang on let me open up the
settings you'd make things safe safe for bellowing bellow safe the bell that's the
opry gordon promise patented bellow safe technology that's how they sell the microphone
for all your left-wing podcasting needs you can shout no as much as you want the package is just
a line drawing of me giving the a-okay and winking like wait so okay the reason i one of the reasons
i wanted to
jump into this was because i actually have a tagline and it's actually kind of good oh my god
i can't wait michael you're already bellowing i am uh welcome to minions phase the podcast that
downs your uppers oh because that's what we're doing today literally we kind of are we're
drinking caffeine we're canceling coffee this is also true of us emotionally people come to us
feeling good and then they listen to our show and they're like oh now i'm down yeah i'm also aubrey
i'm so you said we have to record for like four hours for this one i'm like what are we going to
talk about for four fucking hours so much michael i thought this one was gonna be like 15 minutes
long i thought this was gonna be like a little light easy one to be like we're gonna get more
episodes out it'll be faster yeah i know but then it was us but then this is us starring mandy moore
and i surprised myself by learning that oops i picked out a 72 ounce steak of a topic i'm so
excited michael what do you know about bulletproof coffee how did it make its way onto your radar
what have you heard do you know anybody who drank it or drinks it this is just coffee with butter in
it no yes yes i have not like come across this in the wild i do not like read maxim magazine or like
wherever the fuck people are getting this stuff maxim magazine how dare you what are the metrosexuals
reading these days so the origin story is pretty straightforward the creator of bulletproof coffee
is a guy named dave aspen and he's a guy who's been reading the origin story for a long time and he's
a guy named dave asprey he was hiking in tibet when he tried a local drink okay the local drink
was tea with yak butter in it that is a common drink in tibet okay he tried it and he said he
felt absolutely incredible after drinking it and came back to the u.s to test out a version that he
could make at home that made him feel the same way this is like a person on vacation who's like
i feel great when i'm on vacation and then they want to replicate it when they're home
yeah what if i moved to jamaica he says that as he was experimenting at home he switched
from tea to coffee because the flavor of the butter overwhelmed the tea okay the recipe is
pretty straightforward what you're mixing together is two cups of piping hot brewed coffee
okay up to two tablespoons of grass-fed butter oh it has to be grass-fed sure and up to two
tablespoons of mct oil what the fuck is that multi-chain triglyceride oil dude do you know
what just happened to me what in my life because we're doing a taste test later so i had to go to
the store to look for bulletproof liquids i went to the normal grocery store and they didn't have
anything so i went to whole foods i had to ask the gentleman working there if they had any
bulletproof stuff i got like the coffee grounds and then he also guided me to like the supplements
aisle oh sure i was like why is he taking me to the supplements aisle and then he found a bottle
of like a bottle of liquid brain octane was it brain octane michael i don't it said so many
things on the back it was like dr brawner's there's like all these words coming at me
and i was in a hurry because we were like late to record so i was like yeah whatever fine fine fine
so i get the thing i go to the checkout and it's like bloop bloop i start putting them in the bag
and she goes oh it's uh 75 60 i was like wait sorry i thought you said 75 dollars and then i
looked at the little thing and the it was a bottle of mct oil yep which was 54 dollars jesus
i mean it was a relatively large bottle to be fair but also i was like no podcast is worth 54
i'm not you dropped it yeah i was like put this back there's no fucking way i'm paying 54 for
whatever this is but i think that's because it was like the oil it wasn't like the coffee
butter coffee thing for bulletproof coffee true believers you will hear a few key health claims
about drinking the butter coffee one you will hear that bulletproof coffee quote unquote keeps you in
a fasted state while filling you up okay two people will say that bulletproof coffee leads to
quote unquote enhanced cognitive performance oh yeah three you will hear that most coffee won't
work uh in making bulletproof coffee because it contains mold which outweighs the nutritional
benefits i can't where are we the first claim is that bulletproof coffee keeps you in a fasted state
that's based on a ketogenic
ketogenic diet framework the idea is that this is a meal replacement right we've discussed this
more in depth in our keto episode but cardiologists are not fans of this approach okay i will
absolutely never forget the doctor uh who we talked about in that episode who described the
ketogenic diet as the low carb high coffin diet oh yeah the other thing that this is sort of based
on is not specific to bulletproof
diet it's not specific to bulletproof coffee it's not specific to ketogenic diet it's not specific to
coffee it's based on the purported benefits of mct oil multi-chain triglyceride oil so multi-chain
triglycerides are just straightforwardly fats they're shorter chains um than other fats which
means they're quicker to convert to energy there's less for your body to break down so if you're on a
keto or keto style diet the idea is you want to add some mcts because that'll be your quickest way
to get the kind of energy that you need to convert to energy so if you're on a keto or keto style
diet the idea is you want to add some mcts because that'll be your quickest way to convert to energy
you would otherwise get from carbohydrates the thing is even if the health claims are true aubrey
if it's 54 i'm not interested michael it's not 54 because multi-chain triglycerides are naturally
found in coconut oil and palm oil of course there has been some research into mct oil and mcts
but the benefits in that research are pretty modest and the strength of the evidence is just
not great right i could just drink coconut milk i can put that in my coffee that's going to make me
that probably tastes better honestly than butter claim number two is that it will enhance your
cognitive performance dave asprey says that he ran his own research comparing his bulletproof
coffee beans to other coffee beans so he makes a big show of this he says that he registered with
an irb and that he worked with a stanford researcher on his research design he doesn't
say who this person is what they're credentialed in okay he also doesn't like publish the
results of the study anywhere okay here is his paragraph describing the research design we asked
54 people recruited from the bulletproof executive facebook page to conduct two batteries of
cognitive function tests per day for four weeks while using different combinations of butter and
coffee lab tested upgraded coffee black coffee made with beans from a local shop black lab tested
upgraded coffee with butter coffee made with beans from a local shop with butter we did not test mcts
or coconut oil because the test was already too long and dropout people not completing the test
was a problem nonetheless the results were conclusive love that and we didn't test half
of the recipe a bunch of people dropped out but it was conclusive and we recruited through facebook
54 people anyway this is hella janky but we've also reached sweeping conclusions love that and
we've also reached sweeping conclusions love that and we've also reached sweeping conclusions love that
the coffee from a local coffee shop produced statistically significant lower scores on tests
of cognitive function compared to lab tested upgraded coffee beans yeah i mean this just
has like no plausible explanation they're like your coffee beans are so different that it's
enhancing cognitive function but other coffee beans aren't like yeah i need to see give i need
the tables 100 i read an interview with a university professor on the bulletproof diet and her take
was that coffee beans are so different from other coffee beans that it's enhancing cognitive function
was essentially something that like we've said on the show a number of times which is that
nutritional research is extremely difficult to do yeah just really hard yeah to research an
individual ingredient or compound in someone's diet you would have to have people eating
identical diets aside from that one ingredient or compound for a sustained period of time
and you would have to know that they're not slipping off of the plan
that you have provided for them yeah sort of this is why we try not to like make fun of scientists
or like seem snarky about scientists on this issue just because it's so hard to study michael let's
dig in on that third claim about moldy coffee yeah what is this what's going on i like interviewed
coffee roasters and screeners i like what i went on such a fucking journey about this
it is true that coffee can develop mold the forms of mold that we're talking about here are called
mycotoxins one which is also what i call you when you're in a bad mood that's all my that's all my
friends new year's resolutions mycotoxins cutting mycotoxic out of my life that's my irish friends
call me when they're mad
So one of those types of mycotoxins that can grow in coffee is a known carcinogen.
That's also true.
Okay.
However, in order to consume enough that it would like cause health concerns,
you have to consume so much coffee.
Oh yeah.
You have to, this is our old classic of the dose makes the poison, right?
We are all exposed to low levels of this stuff all the time.
And not just through coffee, this particular mycotoxin, which is called aflatoxin B1,
can be found in peanuts, pistachios, dried spices, and corn, among other things.
So this is in a lot of things in extremely low concentrations, right?
Because of that, coffee growers and roasters take a number of measures to reduce mycotoxins.
One is that. They've developed a process called wet processing.
That is the way that most coffee beans are prepared at this point.
It involves pulping, fermenting, and drying coffee beans.
That's the way coffee is processed now.
Wetly.
After that process, they roast the beans because roasting beans also kills mycotoxins.
And then after all of that,
they disperse.
Discard any crops with unsafe levels as set by the FDA.
So they're marketing something that is like a legal requirement.
Like we pay our taxes.
Yeah.
And to be fair, their argument is we have even fewer than other brands, right?
To none at all.
Like that's sort of what they're saying.
But here's the thing that broke my brain, Mike.
Even if they didn't do any of those things, mycotoxins make coffee taste bad.
So they can't sell it.
Oh, okay.
So there's already like a bill.
It's just an incentive.
Yes.
Yes.
So like mycotoxins change the taste of coffee.
They make it taste extremely bitter.
Okay.
So it also just like wouldn't be in their best interest to try and sell shit that people would then drink and be like,
this is gross.
Yeah.
Dave Asprey says that they don't actually screen well enough for mold.
And that actually Bulletproof is the only one doing sort of some form of proprietary mold screening.
Right.
But he doesn't really go into like, what are they doing?
So he's not technically lying or potentially he's not technically lying, but he's giving you the impression of something that isn't true.
So Michael, are you ready to taste test some goddamn Bulletproof coffee?
Let's do it.
I have not eaten breakfast yet today.
So this is me in a fasting state.
Oh, you're going to do it correctly.
Listeners can weigh in on whether I seem smarter afterwards.
Give me more feedback on my personality.
I really like that.
You and I both got the high achiever from Bulletproof.
Yes.
Which is enhanced.
Enhanced coffee with added B vitamins, lion's mane and coffee berry.
Sure.
I am going to send you the little recipe.
Oh, okay.
And what you're supposed to do is blend it to emulsify it.
Which I cannot do.
You cannot do.
I can do.
So two cups of coffee up to two tablespoons.
I mean, I don't have grass fed butter.
I have like normal ass butter.
Can I read to you the description from the brain octane that you didn't buy?
Oh, yeah.
Do it.
Crave less.
Do more.
Oh, okay.
Brain octane.
C8 MCT oil is no ordinary MCT oil.
Oh.
Sourced purely from coconuts.
I like coconut oil.
Ordinary.
It contains the most ketogenic MCT oil, pure C8 caprylic acid and easy to absorb high quality
smart fat.
Sure.
So that's me.
I'm a high quality smart fat that rapidly converts into brain powering, fat burning ketone energy.
Brain octane C8 MCT oil helps control cravings, jumpstarts your metabolism and improves cognitive
performance to keep you sharp.
It would be so funny if they said it's fortified with mycotoxins, this like special thing that
actually like makes you smarter.
Like it's like any of these like mold is good for you.
Mold is bad for you.
It's all, it's all just people saying stuff.
So Mike, I'm curious about what your coffee looks like.
Mine has been through a blender.
Yours has not.
Mine.
Okay.
There's, when I was living in Berlin, there's like a restaurant in East Berlin that's like
famous for like, it's like the garlic restaurant.
That's like the theme.
Every single thing on the menu has garlic in it, including the desserts.
So they have famously garlic ice cream.
And I was like, okay, whatever.
I'll go there.
I had like a normal spaghetti dinner.
And then I had, I was like, all right, fine.
I'll try the garlic ice cream.
And then you taste it.
And it literally just tastes like someone took Breyer's ice cream and like crushed a
bunch of garlic in it.
You're like, yep, that's garlic in some fucking vanilla ice cream.
It was like not more than the sum of its parts.
I feel like this is the.
It's the same thing where like, it looks like just coffee with like a centimeter of
butter floating on top of it.
And then when you smell it, it's like, it smells like coffee and butter.
There's not, I mean, I don't know what I expected.
Yeah.
I was going to say mine smells exactly like coffee and exactly like butter.
It smells kind of like a diner.
Yeah.
I'm also glad you didn't get the oil because he does warn you about putting too much MCT
oil in your coffee.
Surely it's going to separate.
Yeah.
That's not what he's concerned with.
He's concerned with a side effect that he refers to consistently.
Throughout the book as disaster pants.
Oh God.
What?
Why do all these things involve pooping?
Just give me a normal diet that doesn't change my poop.
There's a new euphemism for shitting myself in my brain.
Brought to you from the era of like amazeballs and awesome sauce.
Please enjoy disaster pants.
We have to, we have to do this very quickly.
The second I stopped stirring, it just like all the butter flows back to the top.
You ready?
Are we doing three, two, one?
Sure.
You count.
Count us down.
Wait, you, you don't say you do the countdowns.
Three, two, one go.
I'm not tasting the butter at all.
Actually.
It just tastes like a fine cup of coffee.
It's fascinating to me because like all of the celebrity coverage was like, it's the
creamiest latte you've ever had.
It's the best.
And I'm like, no, it tastes like drip coffee, which is kind of amazing because two tablespoons
of butter is heavy.
Hella.
I was noticing when I was putting it in, I was like, damn, it's a lot of butter.
It's so much butter.
Do you feel smarter, Aubrey?
Do you, do you, are we sharper?
The appeal eludes me.
I really thought I was going to be like, hey man, I got to hand it to him.
This tastes really good.
Man.
But it tastes just sort of like coffee, like a cup of drip coffee.
So we endorse, we wholeheartedly endorse bulletproof coffee.
No, we don't.
The rest of this episode will be a series of affiliate codes where we tell you.
Michael.
If it tastes fine, all of the health claims are true.
So bulletproof coffee comes to us.
From a real character named Dave Asprey.
He is a self-described biohacker and the headlines about him often include that he has spent
over a million dollars on his own biohacking.
He is also out here pretty constantly talking about how he intends to live to 180.
Women do not talk about how much money they've spent on diets in the same way.
No, and if you did, it would be with like such weird shame.
Yeah, yeah, yeah, yeah.
It would be a bummer.
You wouldn't be like, check me out.
Yeah.
Dave Asprey is a Gen X dude who spent his early career working in IT.
Okay.
On his website, it says, quote, as a true pioneer, Dave was the first person to ever sell a product online.
Oh, well, I mean, maybe.
Totally.
Mike.
How would you even determine that?
Mike, the journey that I went on trying to disconfirm this.
Michael, Michael, Michael, Michael.
It's clear.
So he did sell products online in 1994.
That is the first year.
Like when you look at like retrospectives on like the beginnings of e-commerce, they
talk about 1994 being the first year that people are like figuring out how to sell things
on the internet.
But when people tell that story, they tell a story of like a totally different dude.
And then also a story of Pizza Hut.
Oh, what?
Figuring out some like online ordering through Pizza Hut in 1994.
Oof.
You were not getting that pizza.
That pizza's coming on Wednesday.
You had to wait an hour for the image of the website to download.
So when the story gets told of the beginnings of e-commerce, no one is mentioning Dave Asprey.
Dave Asprey is the one mentioning Dave Asprey.
Can I tell you what the product he was selling was?
Yeah.
What is it?
It was t-shirts with an illustration of the caffeine molecule.
Okay.
And the phrase caffeine is my drug of choice.
Oh my God.
It was like bad, like boomer memes on a t-shirt.
I cook with wine.
Sometimes I even put it in the food.
Right?
Like that's the like level that we're at here.
I was selling cringe t-shirts on the internet when cringe t-shirts were but a glimmer in
your eye.
Wow, Dave.
Yes.
You're like so cool, Dave.
Like most biohackers, he has an origin story that is sort of gussied up, but is ultimately
an absolutely bog standard dieting origin story.
Essentially, he was fatter than he wanted to be and his mind wasn't as sharp as he wanted
it to be.
Okay.
I'm going to send you a quote.
This is from a New York Times profile of Dave Asprey from 2015 and it really sort of encapsulates
that little origin story.
It says. After his failed low-calorie diet, he tried others.
The Zone, Atkins, raw veganism, high protein, and intermittent fasting.
At the same time, he went to extreme lengths to collect additional data on his body's performance.
He had adrenal testing done to better understand how his hormones worked.
Extensive blood work let him monitor his glucose and albumin levels.
He got DNA tests to look for genes that might cause immunodeficiency
and sent out samples of his feces to learn about the microbes in his digestive tract.
He bought an electroencephalogram, or EEG machine, to monitor his brainwaves.
Once, in 2006, hoping to treat gut problems,
he placed an order online for a shipment of parasites called porcine whipworm.
The eggs arrived from Thailand a few days later in a saline solution.
He drank the whole thing, hoping they would trigger an anti-inflammatory reaction in his gut.
But they didn't.
That's what the early internet was, is grifts.
That's the only thing you could get on the early internet.
Cute t-shirts and worms.
Dave Asprey is not himself a scientist, but he credentials himself very frequently
by talking about how he comes from a family of quote-unquote hard science.
Oh, what does that mean?
I'm not a doctor, but my wife is an MD who, not for nothing, in press,
very frequently, they make little notes that are like, his wife disagrees.
Oh.
So he's using her as a credential, but also she says he's full of shit.
And she's like, that's not right.
Yeah.
Also, my dad is a dentist, and I am not qualified to give you advice about your teeth.
One hundred percent.
Like, my dad is a pilot, but I can't fly a plane.
Part of the stolen valor is my wife is an MD, and part of the stolen valor is
my grandparents were scientists.
Grandparents?
And when you go, oh, what kind of science were your grandparents practicing?
He says, my grandparents worked on the Manhattan.
Project.
Oh, to which I say, that's not the flex you think it is.
That's also so fucking weird because it's not anything to do with nutrition.
And also, it's your grandparents, not even your parents.
Right.
They didn't pass that knowledge down to you genetically.
My credentials are impeccable.
My wife disagrees with me, and she can talk to her.
And my grandparents did one of the most infamously bad things for the last hundred years.
So he defines biohacking.
As quote, the art and science of changing the environment around you or inside you
so that you have full control of your own biology.
Now, clue number one that he is maybe not a scientist himself is the phrase
so that you have full control of your own biology.
I kind of appreciate the fact that it's so just like openly fulfilling a psychological need.
One hundred percent.
He's like, this is the way that you can take back control of your body, which you lost control of.
It's like, yeah, we're all getting older, man.
But also, it feels like this weird combo of like men having nowhere to put any feelings that are not like rage.
Yeah, yeah, yeah.
Or victory.
Right.
Right.
And men not being able to take a single fucking L, even one as standard as just like, oh, you have a human body that's aging.
Right.
It's like, but have you considered that I don't want to die?
Totally.
And there's like.
There's this class overlay, right?
Yeah.
Where like Dave Asprey is talking about spending a million dollars.
Brian Johnson is talking about spending multiple millions of dollars.
And there is like this class layer that is like, I'm going to buy the thing that other people, the one thing that other people can't have.
Right.
Which is a version of immortality.
Their only solution to problems is throwing money at them.
So you would think this would be a guy with a lot of systemic critiques of like environmental safety, of regulation.
Right.
Of a bunch of stuff.
And I will say it does not tilt in the direction of good health care for all.
Right.
Of course not.
It never does.
Yeah.
I'm sending you a quote from a Forbes profile of Asprey.
Asprey dreams of a world where instead of deferring to medical experts and profit seeking drug companies, we become experts in our own systems and experiment on them at will.
Unsurprisingly, this has made Asprey suspicious of regulation.
Regulation got us the food pyramid that causes.
Heart disease, cancer, and diabetes in unprecedented numbers of people, he told me.
It got us an incredibly slow to innovate medical system that's now being disrupted.
It is anti-human to tell someone that they do not have the choice to put whatever they want into their bodies.
It's basic human freedom.
I think it's unethical that I need to spend $150 in an hour of my life to get a permission slip to take a substance.
There is no, no reason for that.
Parentheses, Asprey's wife disagrees.
Dude, so he's just like kind of an asshole.
With these kind of like quasi, not quite right wing beliefs, but like on ramp to right wing beliefs.
Yeah.
Or at least like the kind of just like brain dead anti-system stuff that we saw in the Blue Zones documentary where he's like, you're not going to find the truth in some Petri dish.
Except Asprey is like lovingly gazing into the reflecting pool of a thousand Petri dishes.
He's so happy with the Petri dish, right?
Like, oh, narcissus in the Petri dish.
Yeah.
I mean, I think like he does have systemic critique.
But the systemic critiques are like, too much red tape.
Get out of here.
Doctor, who needs a doctor?
Right?
They're bad.
They're bad systemic critiques.
As Bulletproof Coffee sort of broke through, Bulletproof Coffee is getting more and more popular.
And while that's happening, Dave Asprey is busy building a business, right?
Right.
He's selling Bulletproof's own coffee, which he calls, quote unquote, upgraded coffee, which they say is low mold and some of which has additives.
Like adaptogens and that sort of thing, right?
B vitamins, that kind of thing.
They also sell a Bulletproof powdered creamer for your Bulletproof coffee.
So he's gone straight from like, make coffee with these ingredients you can get anywhere to make coffee with these ingredients you can only be 100% sure of if you buy them from me.
Also, yeah, wait a minute.
This just occurred to me because I don't put milk in my coffee.
But like, what's the difference between putting butter in your coffee and putting cream in your coffee?
Not much.
Isn't that something thousands, like millions of people do all the time?
How did this just occur to me now?
Yeah.
I think as far as his thinking appears to go on that front is, well, I used to drink coffee with cream in it, and that didn't make me feel amazing and biohacked.
Right.
This did.
Right.
He also starts selling protein bars with collagen.
Okay.
He starts selling supplements like melatonin gummies and apple cider vinegar gummies and like a greens powder.
Oh, God.
He has a vision supplement called Eye Armor.
Just say this is for your dick.
It's all dick juice.
Your dick will get bigger if you drink this shit.
Please don't say dick juice.
I beg to differ.
Don't call it dick juice.
Men just like need to be told that everything is like you're a gladiator.
You're not taking a supplement.
From there, he starts working on a diet book, The Bulletproof Diet, which is published in 2014.
As part of the book rollout, Dave Asprey got a really significant amount of mainstream coverage.
He gets this profile in Forbes.
He gets a profile in Men's Health.
He gets covered in The New York Times in a stellar profile from Jay Wortham.
And I think the thing that is really notable to me here is that the coverage of Dave Asprey is like a resounding no.
We love that.
It's a rare moment where we get to go, hey, good job, media.
This is like actually the last.
This is the level of skepticism that you should be bringing to any number of miracle health claims.
Right.
The other dust up that he has is, as it turns out, with the FTC.
Of course.
Of course.
I was waiting for this chapter.
What do you think?
Tell me what you what's your guess of what the FTC is citing him on?
It's got to be false claims, right?
It's got to be selling products with like this boost your immunity or something like that's what they got Lucky Charms for.
That letter.
Here's my other clue to you.
That letter was sent in June.
2020.
Oh, I was just going to say, what kind of COVID grifting was he doing?
Is he a certified importer of Pete Evans is like red light that cures COVID.
The letter that they sent him is about a specific blog post on his Web site.
The title of that blog post is what I do to protect myself from coronavirus and how I plan to kick it if I get it.
In this post, he describes COVID as being primarily about inflammation.
Sure.
And then lists.
A bunch of things he does and consumes to reduce inflammation.
What he's referring to is sage, oregano, bay leaf, olive oil, vitamin D, zinc, magnesium, CoQ10, L-glutamine, Bulletproof's unfair advantage supplement, Omega-3 fatty acids.
And all of those, my good man, are Amazon affiliate links.
We didn't even know anything about the virus.
Like actual scientists did not know terribly much about the virus in June of 2020.
Right.
People are wiping down Doritos bags.
Yeah, I know.
With Clorox wipes.
Yeah.
These guys are already promising they know the secret.
Dave Asprey has also been back in the news again in the last few months.
The Washington Post quoted him in a piece just a couple months ago in January.
And I am sending you.
That quote.
It says Dave Asprey, an author, podcaster and self-professed founder.
of the biohacking movement, says he believes Kennedy's influence would even the playing
field with big pharmaceutical corporations and allow companies such as his to make broader
claims about health benefits. The FDA requires positive results in rigorous clinical trials
before drugs and products can be declared cures or designated to treat certain conditions.
This is the dawning of a new age of biohacking because Bobby Kennedy is going to remove the
use of regulations that prevent competition, said Asprey. So he's like, hooray, we're not
going to have to warn people anymore about the side of like, it's so nuts to say that shit out
loud to a reporter from the Washington Post. These guys are basically like, they're openly saying
the FDA won't let us lie to you. There are so many layers to what is going on. And every product
that he sells have like five or six factual claims in the marketing materials. So it's just like
an app, just a thicket of fact checking.
Yeah.
Also, it feels almost perfunctory because it's like every single thing that comes out of his mouth
is like bullshit, bullshit, bullshit, bullshit, bullshit, bullshit, bullshit, bullshit. But it's
cool. My wife is a doctor and my grandparents had something to do with the atomic bomb.
Okay. So Mike, from here, we are going to go ahead and dive into the actual text of the actual
bulletproof diet. That's where we're going next.
Is the name of the book, This Time Baby, I'll Be?
Bulletproof. Good job. Good job.
I'm actually very curious about this because what else is there? It's butter and coffee. It's like
one item. And then you have to build like a whole lifestyle around it somehow.
I'm actually going to send you a quote from the introduction to the bulletproof diet.
That is a really tight little encapsulation of sort of like all of the promises that it is making.
Oh, I want to mispronounce this word so bad to troll people, but I'm gonna, I'm gonna,
I'm gonna do it correctly.
We already had too many fucking emails. Okay. I'm going to say it right.
I'm going to do the Peter thing and start complaining about people complaining to me.
Yes. Okay.
This may seem like hyperbole, but your diet is the foundation behind not only your weight,
but also your IQ, stress levels, risk of disease, physical performance, aging, and even willpower.
You are what you eat. What would it feel like to improve in all of these areas
simply by making better choices about what you put on your plate?
When you begin following the bulletproof diet, you'll know the answer within only two weeks
while losing up to a pound a day and never feeling deprived or hungry.
Oh, sweetie, this is the bullshit they've been selling women for like decades.
Totally.
Just starve yourself, lose a ton of weight, but like you won't feel hungry, bestie.
Totally. But it's from a dude and a CEO and a pioneer of online commerce.
Yeah. And it's, and he's, he's doing this whole like
reducing your stress levels and like high performance. Like it's male coded.
Yeah.
But it's basically somehow like to lose a pound a day, we're talking about
essentially not eating or barely eating. So the idea that you can not eat and also perform well
and not feel hungry, like, I'm sorry that this just is not going to happen.
He claims that he personally increased his IQ through following the diet.
How did I not even mention that? I was like, we don't tie me into the IQ stuff.
Uh-huh. The bulletproof diet includes either nods to or prescriptions to.
The keto diet, intermittent fasting, sleep hygiene, grounding mats, collagen peptides,
raw milk, animal fats, high intensity interval training, anti-inflammatory diets,
and lots of references to your quote unquote lizard brain.
Oh, good stuff. God.
It is just a sludge of 2010s wellness trends.
This is one of those oftentimes people will ask us like, Hey,
is there an episode that I can like send my mom? Cause she's like getting really into
intermittent fasting or something with this. It's like, I'm sorry. You just have to listen
to the entire corpus of the show. You have to listen to 130 episodes because all of this stuff
is shit that we've like addressed in various places, but it's, it's sort of all the same
brand of like grift.
The functional core of the diet is a mix of keto and intermittent fasting, but it has this overlay
of extraordinarily
Byzantine guidance. According to the Bulletproof diet, quote unquote, healthy fats should make up
50 to 70% of your calories for the day. The guidance around protein is a little bit squishier.
He says that you should aim for quote between 0.325 and 0.75 grams of protein a day per pound
of body weight. Okay. Michael, it's time for my favorite.
I didn't want to be the one to ask. Like, what does this mean for you, Aubrey?
All right, Michael, we're doing it. 0.325 to 0.75 grams of protein a day per pound of body weight.
I am currently in the neighborhood of 330 pounds. According to this, I need to eat between 107 and
248 grams of protein per day. How much a dried cod is that? You're on like the rock diet.
Another way of looking at it is in eggs.
17 to 41 eggs per day. That's not even a diet issue. I'm worried about your finances.
So that's your protein guidance. And that's only supposed to make up
20% of the calories that you eat for the day. Okay. So I should be eating 41 eggs and then
five times that many calories of something else. And then like a side of carb-free hash browns,
but like 41 of them. All of that happens within a six hour, quote unquote,
feeding window. This is the fasting thing. Okay. On top of all of that,
there are specific schedules for protein fasting and carb refeeding.
It always has to be so weirdly specific. I'm sending you a little quote.
Once a week on days six and 13, you'll get to try out bulletproof protein fasting to get a
thorough scrub down of your cells that will make you feel, look, and think like a much younger
person. It's important.
to stick to the program on these days and limit your protein intake by eating the recommended
meals. Oh, so you're overeating protein on some days and under eating protein on other days?
Yep. Totally.
This is also your opportunity to refeed on carbohydrates. And I focus the meal plan for
those days to include the most beneficial bulletproof high carb, low protein meals.
Why? Oh, he's just like making things harder than they have to be.
100%.
This is also something we've talked about. The pattern is you make the diet as arcane
and complicated as possible.
So that that way, when people fail, you can always say, oh, it's your fault for not following
this like deranged set of rules.
Well, and I think in this case, right, he's selling this as sort of a cutting edge scientific
kind of approach. And I think there's something about having a lot of really complicated,
intricate steps to follow that gives the impression that it's been really rigorously tested.
So you have to do it this way.
Right, right, right.
That the rigorous testing was like Facebook recruitment.
This honestly sounds like he's like my wario. Like he's on Google Scholar,
reading the abstract, and then like concluding a bunch of things.
So he creates categories to describe what I would call like red light, yellow light,
and green light foods. Okay, here. So describe to me, Michael, what you're seeing here.
It's like a spectrum of foods. And then at the bottom, it's kryptonite. So it's the worst,
and then at the top, it's bulletproof foods. And so at the top, the most bulletproof starches
are pumpkin, butternut squash, sweet potato, the Mike lifestyle, yams, and carrots. And then at
the bottom, the worst starches are wheat, corn, millet, other grains, potato starch, corn starch,
gluten-free powders. And then in between, he's got various other, yeah, like black rice,
wild rice, potatoes. They're all at kind of like different levels of the spectrum.
This seems fine to me, Aubrey. I think foods, I think foods are inherently good,
or bad. We can place them all on a spectrum. Absolutely. And quinoa is one of the worst.
Oh, quinoa's the second worst. Buckwheat, oats, quinoa, coming for oats.
Also, interestingly, white rice is the second to the best tier, right? Second closest to
bulletproof. But black rice, wild rice, and brown rice are like dead center.
Yeah, that's weird because usually people are like brown rice is way better than white rice
because of the extra fiber. That's the level of like granularity we're talking about.
We're talking about here. He has another one of fruits and he's like the best fruits you can have
are blackberries and raspberries and coconut, but blueberries are not very good. What? And
cantaloupe is the worst for you. Wait, what is he basing this on?
He's basing this on like a bizarre little pastiche that he has developed in his brain
of weird little straggly bits of research from different places. Some of this is ranked based
on mold.
Some of it is ranked based on anti-nutrients. Some of it is ranked based on how it personally
makes Dave Asprey feel. And he's not really telling you where the sources of each of those
rankings are coming from. There are studies in this book that have an N of two.
Oh, really? Nice.
One of the studies that I looked at had an N of two.
It would be very funny to like, as a flex, be like, oh, you're basing your health advice on
an anecdote. Mine's twice as good as that. Mine's based on two anecdotes. Actually,
The guidance beyond specific foods
foods is very very strange he has specific guidance on cooking meat he's like the most
bulletproof way to cook meat is to cook it as little as possible why are these guys like this
quote grass-fed animal products are much less likely to contain parasites pathogens and toxins
than those from grain-fed animals so i think it's safe to eat them on the rare side he says this a
number of times because food safety comes from the handling of it after it's been killed it's not
the diet of the animal right when he talks about grass-fed meat he talks about it in opposition
not reliably to grain-fed meat but to factory farming but also grass grass-fed meat is also
made at like a large scale by large corporations it's not as if totally it's not as if like jeff
the farmer down the street is producing all of like the grass-fed stuff this is i think so much
of this stuff does fulfill a kind of psychological need because it feels like he's telling himself
if he's going to eat grass-fed meat he's going to eat grass-fed meat he's going to eat grass-fed meat
i eat the right foods i won't get food poisoning it is self-talk made real yeah yeah yeah he says
that if you do have to cook meat you should boil it oh what quote boiling water prevents oxidation
of fats and proteins because it displaces most of the oxygen boiled meat often isn't particularly
flavorful but it's fine for soups and shredded meat dishes boiled vegetables are healthy and
the extra water you drain away may remove a lot of the oxygen that's in the water
unwanted anti-nutrients oh my god may is doing some heavy lifting in that one that's why
international workers day is in may because it does so much work this is somehow more offensive
to me than like the misinformation because i'm like this is gonna taste like shit dave
he also has guidance on what to do when you're going out to eat at a restaurant
dave asprey writes that when he goes out to eat he brings some things with him
he brings a stick of grass-fed butter he brings a container of brain octane dude mct oil and he
brings some sea salt dude that's so passive-aggressive to go to a fucking restaurant
with your own food sometimes he says he also brings an avocado that way he says he can order
something basic and quote pump it up to meet your news standards i guarantee there's an entire
discord server of waitresses
who've had to serve him at a restaurant like did you get the weird butter stick just this guy came
in with wraparound blue blocker sunglasses and his own mct oil he's like oh just a water please
do you want to know what his breakfast order is when he goes out to eat uh just the waitress's
phone number he says that he orders poached eggs and then melts his grass-fed butter on top and
pours mct oil at a restaurant dave are you going into a restaurant with a stick of
room temp butter in your pot
it's like it's like having like a toddler where you have to explain like no no no this is where
we go and other people make food we don't bring our own food to the restaurant it's like so weird
he says quote i've even done this in four-star hotel restaurants if the chef notices we always
have an interesting conversation again a load-bearing word in that sense
interesting conversation what the fuck is wrong with you bro and listen there are people who have
dietary restrictions who have severe food allergies and then you got these guys with
their optional ass like i gotta live to 180 shit like i just read this whole section about going
out to eat and i was like you are the reason for the no substitutions signs uh instead of having
fries on the side do you mind if i just have uh this
overripe avocado that i brought from my home now i have a quote for you that's just funny i just
read it and it was extremely funny so i'm sending to you because it's funny you may not know it but
you've always been on the bulletproof diet you may have just made poorer choices in the past and
eaten more kryptonite than you have been for the past two weeks but that's because you didn't have
a roadmap or a tool to help you navigate it you were always on this diet you've just been fucking
it up yeah terrible haven't you always been drinking butter in your coffee you just haven't
been putting butter in your coffee you just haven't been putting butter in your coffee
i did not mention to you that dave asprey has a very specific look to him let's let's make fun of
his looks please just once on this show you know what we deserve a treat let's do it head to toe
let's start with the ears no no no damn he is in a constant state of wearing these very funny looking
to me wraparound glasses with like orange yellow tinted lenses does he drive a cyber truck i mean i
surprised okay he has cyber truck energy uh no you know what he has it's not cyber truck it's
segway yeah they're gonna take over we're all gonna be on these things in another couple months
yes that is the meanest thing you've ever said about anyone on this show that is that is the
deepest dig on anyone that's worse than making fun of his look you're like this motherfucker
would have been into segways oh no i've never seen you like this aubrey wow
she's a monster let's just sit in silence and like think about what we've done
some cold shit so i wanted to close this out by talking about some of the core
tactics that he is using here because i think it's a really interesting window into the kinds
of tactics that get deployed in diets that are predominantly marketed toward men a big part of
this book is that he has
tons and tons and tons of footnotes dave asprey is citing his studies he's doing it right what he's
not doing is telling you how hard he is cherry picking this is the thing that people often say
they're like the left is criticizing my book for being unrigorous but i have 74 pages of footnotes
it obviously is the quality of the footnotes and whether you're like accurately describing
what's in the footnotes absolutely and the majority of his citations
that i like checked into are for rat studies really one of the studies was about rats with
kidney disease and he's like that's why humans need to eat this way for the rest of your life
right right the human studies that he cites often have vanishingly small sample sizes
he cites a number of studies that sound like rock solid and he presents them with a great
deal of confidence and only through some pretty extensive
like googling around about the researchers and the topic and who are the voices in the field
do you realize that he's citing a study that has been pretty widely discredited
oh okay he also draws on studies about people with specific health conditions but doesn't disclose
that in the narrative so for example he'll tell you about findings about like blood sugar and
mortality but he doesn't tell you that that study was looking at people with diabetes right oh right
he does this with like uh
kidney stuff he does it with a number of health conditions where he acts as if the findings are
general i i did not read the text of this book obviously but i do think it'd be very funny if
he's like you should drink mct oil and then there's an asterisk and you follow the asterisk
and it says if you are a rat with diabetes i would love it if the asterisk just said no you shouldn't
this is fake but i'm saying it anyway the last thing i will say in this sort of category is
that he really does straightforwardly
ignore counter evidence he never really acknowledges the weaknesses in his own interpretation he never
really says hey if you want to do this with me come on down but definitely like proceed at your
own risk right so it sounds like what he's describing is scientific consensus right but
that's just because he's not really bothered with having a broader more contextualized more
grounded and accurate conversation i want to say it's weird to me but it's
not that weird but it's frustrating that over and over again people refuse to spread the actual
scientific consensus which is that like we just don't know that there's a specific lifestyle that
is going to produce health for every single person i don't find this all that difficult to like
acknowledge and that i can like i love riding my bike i don't think everybody should ride their
bike some people don't like biking it's fine i mean i think in some ways that kind of evangelism
comes from like a really human place of like oh totally yeah i discovered a thing
i really like it and i used to feel bad but now i feel better and i want for other people to also
feel better yeah and my assumption is if it worked for me then it works for everyone this is where we
all reveal ourselves to be like a little more self-centered than we think of ourselves as being
right yeah totally he also throughout the book plays both sides of the same argument i think this
is sort of a human fallibility thing that sometimes we'll say that something like it's a benefit that
something is really
inexpensive and other times something being really inexpensive makes it suspect right i would never
suspect anything for being inexpensive but yes he frequently talks about things that he positions
as being on the cutting edge because there are only animal studies about it or because it's
under-researched in some other way he finds ways to make a lack of research evidence something that
is like good yeah yeah yeah but also when he's talking about things he does not like right he's
is here in his section about artificial sweeteners.
He writes, quote, there have been very few studies on the safety of the artificial sweetener
Ace K in humans, and researchers are concerned about it.
This is scary, and my personal experiences with Ace K are even scarier.
I developed benign nodules on my thyroid from consuming high amounts of Ace K in the late
90s when on an Atkins-style diet.
So you're like, well, you had a bad experience, and you don't trust this thing.
Ergo, you're like, the lack of research is really concerning.
But you tried another thing, and it made you personally feel better.
So you're like, the lack of research just means they don't want you to know.
The lack of research just means it's too new and cutting edge.
Right.
Again, it's a tough one because it is like a human thing.
You and I have talked about this offline.
I think it's part of the reason that I find arguments about people being hypocrites,
like not very effective or moving.
Because we're kind of. I'm not going to pretend I have these content-neutral standards for doing science either.
I'm a biased human being just like everybody else, completely.
So it's a tough one to be like, look out for this thing that humans sort of just do.
But do look out for this thing that humans just sort of do, right?
Because there are hazards in the world that have not been studied adequately.
And maybe it will turn out that there are food additives or something that are causing real harm.
But also, you can't just say, this is harmful because there's no research.
And this other thing, this is good.
This is good because there's no research.
Yeah, absolutely.
And also, again, you have to be willing to trust that Dave Asprey is giving you the correct citations here
and the right numbers and that he's citing them correctly
and that they're like, you know, from like the NIH and not from like movie phone or whatever.
You know what I mean?
Like you have to be willing to trust him.
Right.
But when it's presented in this package of a book that is, you know, several hundred pages long,
and has a ton of footnotes and is flooding you with information that sounds really technical
and is being presented by someone who has an immense amount of confidence in his own analysis,
it's really easy for this kind of stuff to slip under the radar
just because you're getting overwhelmed with so much of what looks like information.
Right.
His approach doesn't immediately present as a grift in part because of all of that sort of like,
sort of like,
scientific veneer that goes over the top of it.
But also because he believes it.
Like I think he really is a true believer, right?
So it doesn't strike you as inauthentic, which means it often will strike people as being true, right?
I really want one of his citations to be to like snap a lid.
1997.
That's it for the show notes, my guy.
Hey, we did it.
We did it.
How are you feeling?
Good.
What do we want to conclude?
I'd just like to remind all of our listeners that you've always been on the bulletproof diet.
You've just been fucking it up.
You've already been there, done that, messed around.
Podcast Summary
Key Points:
Bulletproof coffee, popularized by Dave Asprey, is marketed with health claims like enhanced cognition and fasting benefits, but these lack robust scientific support.
The purported benefits of MCT oil and butter in coffee are based on weak or anecdotal research, including a study with only 54 participants and no published results.
Claims about mold in coffee are exaggerated; mycotoxins are present in low levels in many foods and are naturally eliminated during processing and roasting.
Dave Asprey’s biohacking persona is built on self-promotion, cherry-picked studies, and misleading narratives, including fabricated credentials and overblown claims of scientific rigor.
The Bulletproof Diet is overly complicated, with extreme protein recommendations (up to 41 eggs per day) and rigid fasting schedules that are impractical and potentially harmful.
The diet relies on vague, unverified food rankings and personal anecdotes, with little transparency about data sources or study validity.
Asprey’s approach dismisses counter-evidence and promotes pseudoscientific justifications, such as linking lack of research to hidden danger or unverified benefits.
Despite its popularity, the product and lifestyle are largely ineffective, expensive, and more aligned with a lifestyle of consumerism and self-optimization than real health outcomes.
Summary:
The podcast critically examines Bulletproof Coffee and Dave Asprey’s biohacking lifestyle, exposing a pattern of misleading health claims and pseudoscientific marketing. While the idea of coffee with butter or MCT oil is simple, the health benefits are not supported by strong evidence—research is minimal, often anecdotal, and frequently cherry-picked. The podcast highlights that claims about enhanced cognition, fasting benefits, and anti-mold properties are unfounded or based on flawed logic.
Asprey’s credentials are exaggerated, with fabricated scientific lineage and selective citations, including studies with tiny sample sizes or from discredited sources. His diet is presented as cutting-edge but is actually a collection of outdated wellness trends, like keto and intermittent fasting, wrapped in overly complex rules and jargon. The podcast also notes the absurdity of elements like bringing butter and MCT oil to restaurants, suggesting the lifestyle is more about marketing and personal control than health.
Ultimately, the show concludes that Bulletproof Coffee and the broader diet are not scientifically valid, are expensive, and serve more as a self-reinforcing narrative of elite control over one’s body than as a legitimate health solution. The takeaway is clear: the claims are not backed by science, and the audience is encouraged to question such "miracle" diets and recognize the gap between marketing and medical evidence.
FAQs
Bulletproof Coffee is a mixture of two cups of hot brewed coffee, up to two tablespoons of grass-fed butter, and up to two tablespoons of MCT oil. The recipe is designed to provide energy and is often promoted for cognitive benefits.
Proponents claim it keeps you in a fasted state, enhances cognitive performance, and supports ketosis. However, these claims lack strong scientific evidence and are often based on small or anecdotal studies.
The evidence is limited and often weak. Most studies cited are small in scope, involve animals or have minimal sample sizes, and lack rigorous methodology or peer-reviewed publication.
MCT oil is believed to be quickly converted into energy by the body, especially in ketogenic diets. It’s marketed as a 'smart fat' that supports brain function and energy, though its benefits are modest and not well-established.
Coffee can develop mold, but in very small amounts. The levels found in coffee are generally too low to cause harm. Roasting and processing reduce mold, and the presence of mold in Bulletproof Coffee is not a significant health concern.
Dave Asprey is the founder of Bulletproof Coffee and promotes himself as a biohacker. He claims to have developed the idea while hiking in Tibet, inspired by a local drink made with yak butter and tea.
