Understanding Gary Taubes


I’ve finally solved the mystery that’s been plaguing me for years.  You wouldn’t believe just how much time I’ve wasted obsessing over Gary Taubes, and how he could proclaim, with a straight face, that all of nutritional science is wrong, and it’s carbs that make you fat.  Almost daily, I’d ask myself, “Could he really think all those metabolic ward studies were poorly designed?”  I’d think deeply, then tentatively conclude, “There’s no way he would do this just for money.”  It wouldn’t be worth the constant ridicule from the entire scientific community.  Plus, you couldn’t convincingly fake a position for so long.  But then I’d go back to wondering how he could possibly dismiss all the published scientific studies, and so on, leaving me endlessly looping over this riddle.

As you know, I lost 25 kg on a high-carb, low-fat diet.  This is the kind of diet Gary Taubes hates.  He hates it, because he thinks it’s wrong, and the worst advice you can give to anyone.  He feels the government and “experts” have been pushing it on the public ever since they blew it on saturated fat 50+ years ago, and its unexpected consequences are the current obesity epidemic.  But don’t tell him that people got fatter because of fast food and sedentary behaviour.  He’ll tell you that exercise is ineffective for weight loss, or even maintenance, and we’re even exercising more these days, so it’s the carbs in the fast food that is the problem.  And don’t ever say it all comes down to “calories-in, calories-out”, because CICO is meaningless, and it doesn’t tell you why people are eating more calories, just that they are.  (He’ll tell you that people are eating more calories because of carbs and insulin or something.  It might take an hour to explain fully.)  And don’t tell him that there are billions of people who do fine eating a traditional high-carb, low-fat diet, like the Chinese, because he’ll tell you that they never ate any sugar.  And don’t tell him that there are traditional cultures in tropical regions that eat lots of starch (rice) with sugar (fruit), like the Thai, because he’ll probably tell you that they have specific genetic adaptations for this diet (I haven’t actually hear him say this, but I’m guessing it’d be his answer).

So, no matter what your argument that we’ve evolved eating carbs, etc., he has an answer for you.  They’re the same answers he’s been giving for 15 years, with occasional refinements.  I can pretend to be Taubes and refute each and every one of your points.  Or a bot can do it.  I don’t think I’ve ever heard as much as a equivocal concession from him that perhaps unrefined carbs are okay.

It’s all been mind-boggling to me.  Taubes has some undergraduate education in physics (he says he was a B- student, then got a C- in Quantum Physics [usually the first upper-division class], and finally changed majors to Engineering).  But he’s a celebrated, award-winning science writer.   But anyone with a science perspective, or even any common sense, would guess the carbs vs. fat question has already been studied to death, in many subtle and ingenious ways.   That’s what scientists do.  You’d think it’d have been a dead horse long ago.

But no, Taubes says that “over 80 years of experiments, 80+ studies, 4,094 test subjects, and 1.2 million subject-days” have yielded “no definitive answers” on the matter.  He emphasized this belief in the literature for his “non-profit” NuSI foundation.  Through his Energy Balance Consortium, he’d hope to conduct nusiNoAnswersa series of “Manhattan Project of Obesity” experiments, to finally determine once and for all if it was carbs making everybody fat.  Of course, as all diet-nerds know, his very first pilot study with Dr. Kevin Hall returned an answer last year that his critics expected, but that no low-carber would accept.  Even with wildly different serum insulin levels, there was no statistically significant weight loss difference between an iso-caloric ketogenic diet vs. a high-carb, high-sugar, low-fat diet in their very expensive, two-month metabolic ward crossover study of 17 young, overweight subjects. [1]  Dr. Kevin Hall then pronounced the “carb-insulin” theory of obesity “falsified”. [2, 3, 4]  Not surprisingly, NuSI subsequently lost its funding, through Taubes stays on, unpaid, seeking new wealthy investors [5].

But of course, this still doesn’t change Taubes’ mind, or even make him consider alternative possibilities (like everyone else is right).  His spin on the whole affair is that the data supports his position.  Which just left me more astounded, wondering how he could see it that way.  I never believed he could be a deliberate fraud, because those guys are so obvious.  And he didn’t seem like a total crank, because they all have tell-tale signs too.  (For example, Tim Noakes comes off as a sincere but total crank, Mark Hyman looks like a con man, I’d trust Mercola as far as I could throw him, Peter Attia is a NPD blow-hard capable of crying on cue, etc.  Without exception, they’re 100% detectable.)

But Taubes fooled me with what sounded like pleas for scientific inquiry.  This will always get a nerd’s attention.  I never believed a word he said, but he fooled me into thinking he was actually looking for an answer.  So like Lucy and Charlie Brown, he’d tee up the football of “prove me I’m wrong” in front of us, tempting us to run up and kick the ball out of the park, but he’d pull it away at the last moment, leaving us dazed and embarrassed, but more determined to try harder the next time.

Plus, there was the implied transitive law of inequality involved!  If GT was greater than all of science, and I was greater than GT, then I’d be greater than all of science.

So last weekend, I finally got my chance to kick the ball out of the park, at an intimate book-signing affair for his latest “The Case Against Sugar”.  I drove two hours north to Pasadena in the pouring rain, and arrived early enough to sit in the front row, just feet away from the object of my obsession.  There were only about 60 people in the room, and well-known skeptic Michael Shermer would interview him, followed by a 45 minute Q&A session with the audience.

Ok, honestly, even though I’d long day-dreamed about the line of questioning I’d put to Taubes given the chance, I knew I wasn’t even going to ask him a single question that day.  I knew it’d be useless.  No matter what you’d ask, he’d already have a pat answer prepared, or he’d use the same rhetorical techniques he’s used over the last 15 years.  (He’d aggressively interrupt you, pretending to be interested in some scientific aspect to consider, and end up taking over your question, etc.)  Plus, there’s always a lot of other people asking dumb personal questions, so you’d never get much time.  And I was just obsessed about his motivations, not his bad science.  And I’m a horrible speaker.

[Actually, the guy sitting next to me, Peter Voss, a stick-thin calorie-restrictor of 19 years, ended up in a mini-debate with Taubes over “calories-in, calories-out” (CICO).  Voss said you could control body weight by adjusting the calories you ate, and Taubes got slightly agitated and repeatedly told him CICO was “meaningless”, and started with the whole “let’s say you have a lot of people in the room” hand-waving analogy, making things less clear.  Gary controlled the guys question until no one knew what they were talking about anymore.  Oh, and Gary told the CR’er he could eat more if he focused on fats.]

But all during the talk, it became clear to me that Taubes was fixed on his belief that nutritional science had got it wrong, and that he’s the only person in history to review the literature and realize this, and to make a scientific argument against CICO (i.e., his 2007 book “Good Calories, Bad Calories”).  He can say this with a straight face is because he knows he’s right.  Carbs make you fat.  Plus, he’s built up a whole belief system and set of fact-twisting arguments supporting it.   He’s long done listening to any counter-evidence.  He’s worked out every reason to dismiss it all, via misinterpretation or mischaracterization, if necessary.  

Taubes literally believes that everyone else is wrong, and only he is right.   [He told us that conventional nutrition scientists all suffer from groupthink, and no one will rock the conspiratorial boat.]  Occam’s Razor tells him he’s right.  He refers to it frequently lately, because while he admits he can’t prove his assertions, he says that Occam’s Razor supports his hypothesis.  Of course, this drives me crazy, because he insanely misinterprets Occam’s Razor.  He describes it as preferring the explanation with the fewest number of elements.  And since the conventional explanation for the obesity epidemic is “complex and multi-faceted”, it basically loses by [his] definition.  Of course, Occam’s Razor prefers the explanation with the fewest assumptions, which is just a proxy for overall likelihood.  (Consider the probability that every nutritional scientist got it wrong over 50+ years, AND they’re suppressing the truth, AND no one except Taubes can see it, etc. vs. the probability that “people just like to sit around and eat”.)

For someone uniquely holding the solution to the global obesity crisis (Is it carbs, or is it sugar this time?  Someone from the audience asked him this, but I don’t remember his answer.  It must have been long-winded), you’d think that science would come running to hear the details.  Oh I forgot, there’s a conspiracy.

I don’t think Gary Taubes is a fraud, as Evelyn (aka Carbsane) has claimed.  At least not in the mustache-twirling way, scheming how he’s going to get rich by making us all believe that carbs make us fat.  He’s more of a vocal, biased partisan making a living from his passions.  I don’t have any problem with that.  (I used to worry about the mustache-twirling, but I feel better now after meeting him and seeing how he thinks.  Hint: like a lawyer who will twist facts.)  Bottom line, he’d still probably insist that carbs make us fat, against all the evidence, even if no one was paying him for his views.

Although I had plenty of opportunities to corner Taubes and waylay him with a few one-on-one questions, I completely avoided it.  I kept it to a few words in the reception line, and gave him his space as we were getting our coats. He knew I was a critic.  If he wanted to discuss anything, I’d let him initiate it.  But we let it alone.  The most we acknowledged of the multi-year, fairly personal, raging online diet wars was Evelyn.  “Who?”  “Evelyn from Carbsane.”  “Oh, Eeeviee!”  That made my trip.

Look, Taubes gets it constantly, probably from his normal-eating friends, and maybe even from his semi-vegetarian wife.  It’s not an act, or at least he never breaks character.  He’s heard it a million times before.  He didn’t need to hear it again from me.  That’s the best thing about meeting someone personally versus flaming each other on Twitter.  You recognize that the other person is a human being.  (I’m a grown-up.  I know that wrestling isn’t real.  Taubes does too.)

The summary.  Yes, he really believes it.  No, he can’t prove it.  No, he’s not listening to any counter-evidence.  No, he’ll never change his mind nor admit to even the smallest of conceptual mistakes.  Why?  Because he’s more like a smart lawyer who never breaks character, and not even close to a scientist.  Besides, there’s no going back at this point.


  1. ” And don’t tell him that there are traditional cultures in tropical regions that eat lots of starch (rice) with sugar (fruit), like the Thai, because he’ll probably tell you that they have specific genetic adaptations for this diet (I haven’t actually hear him say this, but I’m guessing it’d be his answer).”

    Actually I saw him saying something like it on video (just check out the first 25 seconds): https://www.youtube.com/watch?v=vUMaNjYPcbU

    As an American-born and raised, but ethnically Chinese person, I find it ignorant and racist. “Hence, Buddha.” Really Gary? Anyhow, I became obese eating the SAD (Standard American Diet). According to Gary, that’s supposed to be unlikely to happen because it’s “High Carb.” Yeah, and also High Fat but let’s just attack the carbs. Even though I managed to drop the weight comfortably on a diet even higher in carbs and lower in fat than the SAD.


    1. Yeah, Taubes will put together any half-random string of slightly connected ideas together as a “refutation” of evidence that contradicts his hypotheses. You can’t take him seriously. It’s WWF wrestling.


    2. Taubes has stated in writing (“Why We Get Fat,” last chapter) and in interviews that he thinks that high carb diets are probably fine and do not cause obesity in populations that have not been introduced to sugar, which he argues uniquely causes insulin resistance (“The Case Against Sugar”), and thus metabolic syndrome.


  2. It’s funny how you describe Peter Attia. I always thought he was more like a science nerd. Any particular reasons for that? I never came across any critique of his views. Usually it’s Taubes, or Teinholtz, or DietDoctor with Jason Fung.


    1. Just thought he loved the sound of his own voice a bit too much. Usually, if you actually have a clear, notable scientific point to make, you don’t need so many words. That, probably combined with his association with Taubes, his crying TEDx talk, and the way he policed his comment section in his blog, made me very suspect of him. I do admire the fact that he seems to have backed off from the claims of keto metabolic advantage tho.


    2. I recommend you watch the NuSI Guys series of videos on YouTube by Plant Positive if you’d like a critique of Attia (and Taubes). The videos are part of a series entitled The Drivers of the Herd. He devotes 10 videos to destroying these guys. Here’s a link to the first NuSI video, which is actually number 11 in the Drivers of the Herd series https://youtu.be/Gap7v2fNpas?list=PLv3QDzdxan_IVgksyJDGR_PO6noKU0r_1 (whole series playlist included in link).
      I actually recommend watching the entire series, as well as the other three series that Plant Positive has made. This guy is great, he’s made over 30 hours of videos debunking all this crap.


  3. Hmm. “No, he’s not listening to any counter-evidence. No, he’ll never change his mind nor admit to even the smallest of conceptual mistakes.”
    After plowing through this unsatisfying screed, I think you are actually describing yourself.
    I watch a lot of diet videos from multiple viewpoints: low carb, all starch, vegan, low fat, etc. And, I’ve read Why We Get Fat. My observation is that the folks who spend their energy attacking, criticizing, and denigrating their opponents, are the least informative, the least informed, and offer the weakest scientific basis for their points of view. You may not agree with Taubes’ opinions, but you haven’t offered a single reason-based counter argument to his fundamental thesis that excess carbohydrate consumption is the primary cause of obesity.
    Stating that the insulin explanation is too complex, does not invalidate it. Rather it makes you sound too lazy intellectually to understand it.
    One final comment. What did you mean to suggest by reporting that Taubes earned a C- in quantum physics? How could that have any relevance to the topic at hand? And finally, what did you earn in quantum physics at Harvard?


      1. Congratulations on your A from Berkeley. I wish you had shown some scientific reasoning skills here instead of merely offering slam after slam.

      2. I’m just expressing my exasperation over the whole demonizing carbs thing. Sure, engineered carb+fat junk food is probably driving chronic, conditioned overeating and the obesity epidemic. But why would Taubes still think that there’s some metabolic advantage to a ketogenic diet? Controlled metabolic ward studies all show, to no surprise, that it’s energy balance that determines fat balance. To a very good first order, it’s all that matters. You can swing serum insulin levels by a factor of 2x, and still, it’s energy balance that matters, to within limits of instrumentation. But even with billions of dollars spent on these well-controlled and ingenious experiments, and he just dismisses all of them.

        I blog about this for my own sanity. If you read my other posts, you’ll see that I’ve come to understand that we’re all biased, and we don’t, and cannot, see the other side’s perspective. That’s why we have these standoffs. We’re not rational. And we can’t even see it.

  4. Some approaches work for some individuals. Other approaches work for other individuals.
    We can chose to be rational. Making Gary Taubes a lightening rod for your frustration doesn’t make him look bad; it makes you look bad. Argue the facts, or don’t argue at all.


    1. Why don’t you have a watch/listen to the videos I linked to on Taubes/Attia in the comments above? If you do so with an open mind, and put your biases aside, you may see Taubes for what he really is.


      1. OK, I’m 2 videos in, and I can’t believe how much he misunderstands what Taubes is saying. I am intimately familiar with Taubes’ arguments about energy balance, and this guy absolutely butchers it. How can he debunk when he doesn’t fundamentally understand the arguments?

      2. Like I said in my original comment, watch with an open, critical mind and put your biases aside, which you clearly haven’t. If you’ve spotted problems in his logic, then why don’t you point out these logical inconsistencies and then correct them or offer them up for discussion? Just claiming hi logic is wrong, but then not stating why, is really an argument at all. So, come one, what’s wrong with his logic? I’d actually be really interested, as I spent ~6 months trying to dubunk this guy. The only problems I came across were already noted on the errata page of his website.
        All this aside, you can’t really argue with the fact that what this guy points out is that the references cited by Taubes and Attia don’t support their ideas. They twist, misquote, misrepresent and even flat-out lie about what they say. This is shown clearly in the videos, something you can’t argue with despite your ‘logically challenged’ claims.
        If Gary’s theories are correct, why does he have to resort to these tactics?

  5. CICO wins, I don’t think Gary disputes that. The problem is when you only talk about “the energy balance” it doesn’t talk about WHY.

    Excess carbs promote hunger and replacing carbs with fat promotes satiety. Excellent appetite control promotes weight loss (CICO).

    As a previously obese person, calorie restricted diets always had me bouncing back to being fat again, I still had my health issues, and was ultimately miserable. As soon as I tried a keto diet and got to a point of fat-adaption and over all carb cravings, it was the easiest way I ever lost weight. I stayed full long and ate much better foods. I could also go on long fasts and let my body fat get burned for energy vs feeding my face with carbs.

    Some people are able to somehow use just simple caloric restriction and might do well. Others just can’t. Is it insulin? Sounds very convincing but that really doesn’t matter to me. All I know is a high fat and low carb diet works very well for some people and it provides the WHY that has always been missing as the reason I so easily over-ate on a traditional high-carb diet.


    1. Excess carb doesn’t promote hunger. Tasty, calorie dense, fibre bereft food does.

      I was a firm believer in low-carb diets and their effect on satiety. They are satiating, but at what cost?

      After three years, and a weight plateau, I decided to do an experiment: try a low-fat, high fibre diet. You know, like the ones recommended by major health institutions? This started out as weight gain experiment, as was in full low-carb la-la land, believing that carbs make you fat. What happened? Turns out I can eat ad libitum, be fully satiated and lose weight. Not only that, I lost more visceral fat, lowered my cholesterol (which was through the roof on LCHF), lowered my blood pressure, and improved my fasting BG and HbA1c. I can now move my bowels again and my kidney problems also went away.

      So why should I go back to LCHF? I don’t see any reason to.
