So, I’ve liked this series (and upvoted it), but I’ve had mixed feelings about the most recent post. It feels like this is verging dangerously close to “someone is wrong on the internet” (1) territory.
In particular, something that seems to me like a major failing is that I’m now 4 posts into a series on nutrition and I don’t know the right answer. I don’t even know your best guess as to the right answer. Without an executive summary on “the right answer to nutrition” this series has no actionable take away points. Its clear to me that a lot of research was done to write this series. The series would be more valuable if you shared the fruits of that research.
Actionability aside, not stating a view on what someone ought to conclude makes it hard to see just how wrong Taubes is or isn’t. Will following his advice kill me? (Taubes is a dangerous madman). Will following his advice cause me to gain weight or fail to lose weight? (Someone is wrong on the internet). Is Taubes directionally correct such that following his advice will cause me to lose weight but he overstates his case while taking rhetorical cheap shots at strawmen? (Someone is technically incorrect on the internet).
One other point I should make: this isn’t just about “someone” being wrong. It’s about an author frequently cited by people in the LessWrong community on an important issue being wrong.
Indeed, I’m not sure I’d know about Taubes at all if not for the LessWrong community.
I’ve already mentioned Eliezer’s “Correct Contrarian Cluster” as an example in another thread, but perhaps it would be helpful to mention other examples:
In a thread where someone asked what the evidence in favor of paleo was, Taubes was the main concrete source that came up. Specifically, Luke mentioned Taubes as the person he’s “usually” referred to on this question, without taking a stand himself and saying he didn’t have time to evaluate the evidence personally.
Sarah Constantin (commenter at Yvain’s blog, author of reply to Yvain’s non-libertarian FAQ, and I just learned a MetaMed VP) has cited Taubes a couple times partly to make a libertarian point.
Jack bringing up Taubes in offline conversation
Yvain’s old blog had a review of Taubes which doesn’t seem to be public right now, but which I remember as partly criticizing Taubes but also lauding him for things that now I don’t think Taubes deserves credit for.
So Taubes was someone I could expect to see cited in the future when the issue of expert consensus gets discussed on LessWrong. In spite of all the people who didn’t like these posts, I think I may have accomplished the goal of getting people to stop citing Taubes.
Taubes is now involved in an initiative with the Arnold Foundation doing randomized nutrition trials. It would be interesting to make predictions about some of those.
If they do stop citing Taubes, I predict they start recommending the Perfect Health Diet. I think the correct response would be to suggest they write a summary, not write a series of articles rebuking the diet, so that we can question them and not the other way around. Make the people with novel advice do most of the work.
It started out that way, but over time it seemed like over time the response morphed into, “okay, Taubes is wrong about thee things but so what?” Jack even made the argument that Taubes isn’t a rationalist so it’s unfair to hold him to that standard.
The OP has attacked Taubes on a peripheral issue and used that to make it look like Taubes got it wrong on his central theses. And I don’t think he did.
Even on this peripheral issue, I think Taubes is actually basically right. I have read 3 of his books and watched a few of his talks so I know his views on the topic.
Overwhelmingly the advice to consumers has been eat less move more. As if that was a solution to the problem of weight gain. My own doctors have said this to me. Not a word about more sophisticated approaches to regulating appetite and hunger.
The scientific rationale for the 2015-2020 guidelines has barely a thing to say about this. They have some ideas about eating less sugar and less takeaway food but evcen there the main argument is the hoary old chestnut about calorie density (fat = 9 calories / gram versus healthy carbs at 4).
Of course you can find some quotes suggesting that regulation of weight is complex. But overwhelmingly the message is calories in calories out. Ancel Keys—who dominated the field, and was funded in part by packaged food companies—gave this message repeatedly in his works.
Dietary policy in the US (and therefore in most of the world) has been a monumental failure with skyrocketing rates of obesity and diabetes. The fall in smoking rates and better treatments have masked the impact of this on heart disease.
There is a long and sad history of the recommendations not being evidenced based and being skewed by the packaged food industry and by vegetarian/vegan zealots (particularly more recently).The AHA’s original big funding splash came from Proctor and Gamble, who marketed the wonder food, Crisco, full of “healthy” trans vegetable fats.
Read the reports over time and look at the evidence that wasn’t there and the evidence that was ignored.
As an example here is copypasta from the latest dietary guidelines:
Adults who are obese should change their eating and physical activity behaviors to prevent additional weight gain and/or promote weight loss. Adults who are overweight should not gain additional weight, and those with one or more CVD risk factors (e.g., hypertension and hyperlipidemia) should change their eating and physical activity behaviors to lose weight. To lose weight, most people need to reduce the number of calories they get from foods and beverages and increase their physical activity. For a weight loss of 1 to 11⁄2 pounds per week, daily intake should be reduced by 500 to 750 calories. Eating patterns that contain 1,200 to 1,500 calories each day can help most women lose weight safely, and eating patterns that contain 1,500 to 1,800 calories each day are suitable for most men for weight loss. In adults who are overweight or obese, if reduction in total calorie intake is achieved, a variety of eating patterns can produce weight loss, particularly in the first 6 months to 2 years; [9] however, more research is needed on the health implications of consuming these eating patterns long-term.
One other point I should make: this isn’t just about “someone” being wrong. It’s about an author frequently cited by people in the LessWrong community on an important issue being wrong.
Not experts on the topic of diet. I associated with members of the Calorie Restriction Society some time ago. Many of them were experts on diet. IIRC, Taubes was generally treated as a low-grade crackpot by those folk: barely better than Atkins.
In particular, something that seems to me like a major failing is that I’m now 4 posts into a series on nutrition and I don’t know the right answer.
There seems to be pretty strong reason to think the right answer is “we don’t know the right answer yet.”
Actionability aside, not stating a view on what someone ought to conclude makes it hard to see just how wrong Taubes is or isn’t.
If you check out Guyenet’s post (linked here, ChrisHallquist has linked it twice), he leads off with (paraphrased) “carb-free diets have worked for a lot of people, and that’s great, but Taubes is wrong about the carbohydrate-insulin-hypothesis.”
This article series began because the heuristic of “trust the expert consensus” was called into question, and Taubes came up as an opponent of the nutritional consensus, but it turns out that Taubes is mischaracterizing the expert consensus, even if he’s not mischaracterizing the layman consensus (which, as you’d expect for laymen, is pretty bad). So that Taubes gets the expert consensus wrong is relevant to the meta-point of “trust the expert consensus.”
I wish people went to greater lengths in explaining themselves whenever they give contrarian advice here, maybe write a post of their own if the issue is important enough. That would make these kinds of posts obsolete.
Often I see some superficially weird off topic statement with upvotes indicating many people agree, although no actual discussion has taken place here regarding the issue, and I have no idea why I should believe it. Engaging those comments is rarely fruitful, but that could be my bad, and of course I probably make weird statements too, since I have little in common with a typical lesswrongian.
I completely agree with this post. A big issue that I have with it is that Taubes’s (and Atkins) advice really does work for a lot of people. Evidently, Atkins and Taubes discovered something that worked, and tried to justify it with cherry picked science. They are salesmen, not scientists, so it isn’t really surprising that their claims aren’t rigorous. (EDIT: This summary of meta analyses on low carb diets backs up the efficacy of their diets)
I’d like for ChrisHallquist to have investigated why low carb diets work so well for so many people, despite the fact that the evidence isn’t all there.
As for your questions, I’d say that following Taubes’ advice won’t kill you, will very likely result in weight loss, and that his methodology is more-or-less correct but his justification is lacking.
I do plan on writing a series of posts on nutrition, exercise, and general health that are actionable with good recommendations.
This is such a weird, non-LW-type response compared to what I’ve become accustomed to.
It seems irrelevant whether or not Atkins “works” if the reason it works has nothing (or little) to do with the reasons being given.
In my experience, the fitness community is full of noise—people who are sure their fitness plans “work” because “look at the great results!” But their justification is so bad that the advice is essentially meaningless.
Or people will swear that X supplement changed their life because they started taking it and presto! 90 days later they had lost 30 pounds, increased muscle tone, and doubled their energy level! Oh...and by the way, they had also concurrently started eating a clean diet, working out 5 times a week, meditating and sleeping more consistently during that 90 days.
As you said, it is important to figure out why the Atkins diet works (when it does). But simply concluding that it is good to follow Taubes advice since it can’t kill you and it seems to work for some people is akin to saying you should give horoscopes a try because they are kinda fun and strangely accurate (when they are). You haven’t gotten any closer to an accurate map.
I don’t think that’s what he’s saying, I think he’s saying “there really appears to be some sort of effect there, so I’d really appreciate if somebody would try to support it with proper research.”
I agree. falenas108 is completely correct that this is an instrumental vs epistemological rationality thing. Taubes and Atkins are both epistemologically suspect because they’re salesmen, not scientists. Going too far into the specifics on why their arguments are bad seems like a waste of time to me, given that you wouldn’t expect truth seeking out of salesmen in the first place.
I think the issue with bad epistemology in regard to nutrition is, for one, the potential for long term harm. Any principle that is epistemologically sound would account for that. Bad nutrition advice does not need to.
Giving people a pass because they are not scientists is fine to the extent you don’t then apply their ideas to your nutrition and your body. Taubes, or many other pieces of bad nutrition advice might not kill you… at least not right away.
Now, I don’t think Atkins or anything Taubes says is that detrimental to long term health. But I think there are plenty of cases where salesmen and scientists end up promoting bad nutrition ideas that do have negative long-term effects.
Anyway, it is just interesting to me that anyone from LW takes Atkins seriously at all.
From my wiki-research, the 1st phase is two weeks and involves eating up to 1680 calories per day. From my recall, this is about 1000 less than the average American male’s intake.
That is a 14,000 calorie deficit over the course of two weeks, which is a ~4lb loss. Add to that the following considerations:
1680 calories is the target, with only 20 grams coming from carbs. 100 grams comes from fat; 150 grams comes from protein. It can be very challenging to find ways to consume 150 grams of daily protein consistently given the other types of food restrictions that Atkins has. I suspect most people don’t do it, so, as long as they keep to the 20 grams of carbs and 100 grams of fat, consume even fewer that 1680 cals per day.
Many people (as evidenced by the fact the gym will be packed tomorrow) begin an exercise regiment concurrently with their diet.
Of course, given these data, you are gonna see some results! Atkins seems to make it so many people will eat substantially less. And many of those people will start to exercise more, just ’cuz they are trying to be more active along with their diet. And that is great!
What I’m hearing in the discussions on this series is that the Eat Less, Exercise More conventional wisdom of weight loss is too obvious, too simple, not true, & downright offensive for many people on here.
It seems irrelevant whether or not Atkins “works” if the reason it works has nothing (or little) to do with the reasons being given.
That’s a strange sentiment. There are people who care about losing weight. It might be surprising but those people do exist.
If you give them a working solution they are happy, even if your theoretical underpinnings are off.
There are people who care about going to heaven. It might be surprising but those people do exist. If you give them a “working” solution they are happy, even if your theoretical underpinnings are off.
We assume that something like losing weight exists in the real world.
If we would assume the same thing for going to heaven, I would want to follow heuristics that bring me to heaven. I don’t really care whether given my a beggar a dollar brings me nearer to heaven because it’s me showing compassion or because it’s a sign that I’m not greedy.
The core question is whether giving the person the dollar works as a strategy for raising my chances of going to heaven. Different churches might have huge disagreements about finding the real reason, but I don’t care that much about those reasons.
If you say that you don’t care about whether something is working, that’s declaring faith in the church of mainstream science, where adherence to virtues is more important than utility or consequences of actions. Is that really your position?
I’ve got this idea for a workout plan to increase your muscle mass: Buy these Magic Muscle Beans from me AND workout with weights 4 times per week for 6 months. You will experience tremendous results!
My point is that the Atkins Diet and every other Diet! basically combine common sense, well-established, mainstream health heuristics with magic.
Magic Beans and Heaven and The Perfect Diet! might exist, but my guess is they are superfluous, and used only to line the pockets of those who cite them as real.
It’s very valuable to distinguish between whether something works and whether the theoretical underpinning is correct.
Usually there are years between the one and the other.
Einstein formulated the theory of special relativity decades before it had strong empirical evidence. That’s having theory before empirical confirmation.
Washing hands before operating a person is the other case. Even before you know about bacteria and viruses you should start washing your hands if you see that having clean hands generally reduce the number of complications in operations.
The people who advocate washing hands might tell you some magical theory about how washing hands means that you smell better and that your patients are less likely to develop complications because you smell better.
It’s a lot harder to find out that bacteria cause illnesses than to find out that surgeons who wash their hands achieve better results.
On the same token it’s easy to observe that many people who adopt a low carb diet, do lose weight on the diet.
Whether it’s due to changes in insulin production, ketones-in-the-urine or some other factor is a harder question.
It’s certainly nice is someone is right about the reasons why the diet he advocates works but the person who’s suffering about overweight cares primarily about whether the diet works. A person who’s in the advice business is generally forgiven if his advice works but his theory is off.
Einstein formulated the theory of special relativity decades before it had strong empirical evidence. That’s having theory before empirical confirmation.
ITYM general relativity—the Michelson–Morley experiment had been performed 15 years earlier. (OTOH IIRC Einstein said he didn’t remember whether he was aware of it in 1905.)
As far from what I remember from school Michelson-Morley did show that not all was well with the prevailing physical model. I don’t think it provided enough evidence to validate that Einstein was completely right.
I think that for many people, getting fit (even if they arrived at fitness with incorrect justification) is far more important than spending time analyzing the theoretical underpinnings of fitness. Same thing with going to haven, choosing right cryo-preservation technique, learning to cook or any realm of human activity where we don’t learn theory FOR THE SAKE OF BEING RIGHT, but we learn it FOR THE SAKE OF ACHIEVING X GOALS.
I mean, I concur that having vastly incorrect map can result in problems (injuries during workout, ineffecting training routine, ending up in hell) but after you update a map a bit you hit the point of dimnishing returns, and it is probably better to focus on practical part than to theorize (especially in the realm of physical pursuits).
but after you update a map a bit you hit the point of dimnishing returns, and it is probably better to focus on practical part than to theorize
Um, yep. And that has been position all along on this series of posts. I’ve said why I think Atkins works and why I don’t think it has anything to do with why the Atkins diet is said to work.
Eat Less, Exercise More for weight loss.
Lift More for strength training.
Of course there are lots of exceptions, and plenty of nuance within these heuristics. But you said it best: The diminishing returns happen quickly for most people and most advice.
My point was only that if someone wants to sell you Magic Muscle Beans and a workout plan that says Lift More, don’t buy the beans.
The main problem with Taubes, I think, is that he fails to cleanly separate the two issues in question:
Why people have been getting more obese.
How to lose weight.
These are very different problems.
Why have people been gaining weight, on average? The reasons are complicated and Taubes gives important insights (even though, as OP said, his criticism of mainsteam nutrition is unfair).
How to lose weight, though, is a different matter. Every source I consult seems to agree that the reason the Atkins diet works is mainly because it makes it easier to eat less, by severely restricting the types of foods you can eat and also possibly reducing hunger pangs. I have yet to see any study consistent with the idea that a Atkins-type diet inherently makes you lose more weight than a conventional diet from mainstream nutritionists (if you match the number of consumed calories). I’d love to be proven wrong, but it seems that if Atkins works for you, other types of caloric restriction diets will also work, long-term.
I do plan on writing a series of posts on nutrition, exercise, and general health that are actionable with good recommendations.
Don’t expect it to generate any less controversy. I think it was Dennett who said that everyone thinks they’re experts on consciousness because it’s such a constant part of their lives, which makes it difficult for them to respect an expert philosopher on the topic. Well, everyone’s an expert on moving their bodies and stuffing food in their mouth and gaining or losing weight too. Giving them advice is a violation of their expertise, unless they’re looking for advice.
I think it was Dennett who said that everyone thinks they’re experts on consciousness because it’s such a constant part of their lives, which makes it difficult for them to respect an expert philosopher on the topic.
Gravity is also a part of everyone’s lives. Yet people respect Newton.
Very special conditions have to exist for conversion of time spent into greater correctness. These conditions do exist for physics or physiology, but they do not seem to exist for philosophy of consciousness.
I think respect was a poor choice of words to begin with. Perhaps people here don’t like Dennett, I don’t care much about him either.
If physicists tell laypeople something that contradicts their experience of gravity, like gravity affecting passage of time, some of them will have hard time accepting it. For laypeople, nutrition isn’t about physiology, and if their experience of weight loss for example contradicts expert advice, again they will have difficulty accepting it.
Change philosophy of consciousness to study of consciousness, and people would probably dismiss philosophers as well as neuroscientists if their findings didn’t fit their experience. I think many philosophers of consciousness cite neuroscientists, so their conditions are pretty special too.
Following his advice can result in chronic ketosis, read the article yourself to draw your conclusions.
Furthermore, there’s a wealth of contradictory data which he fails to report or distorts. For instance, Japanese eat high-carb low-fat diet (calories coming largely from white rice) and have very, very low prevalence of obesity, colon cancer, etc. Even more relevantly for Caucasians, obesity rates in Europe used to be very low fairly recently (and are still significantly lower than in the US), without being particularly low in carbohydrates—and the changes are very easily observable (fast food, soft drinks).
As for whenever his diets are effective for losing weight, that is a very complicated issue, largely psychological in nature. Perhaps some people can be more motivated when they follow unusual / non-mainstream advice, where success proves them right and their boring doctor (who recommends cutting fats) wrong.
So, I’ve liked this series (and upvoted it), but I’ve had mixed feelings about the most recent post. It feels like this is verging dangerously close to “someone is wrong on the internet” (1) territory.
In particular, something that seems to me like a major failing is that I’m now 4 posts into a series on nutrition and I don’t know the right answer. I don’t even know your best guess as to the right answer. Without an executive summary on “the right answer to nutrition” this series has no actionable take away points. Its clear to me that a lot of research was done to write this series. The series would be more valuable if you shared the fruits of that research.
Actionability aside, not stating a view on what someone ought to conclude makes it hard to see just how wrong Taubes is or isn’t. Will following his advice kill me? (Taubes is a dangerous madman). Will following his advice cause me to gain weight or fail to lose weight? (Someone is wrong on the internet). Is Taubes directionally correct such that following his advice will cause me to lose weight but he overstates his case while taking rhetorical cheap shots at strawmen?

It started out that way, but over time it seemed like over time the response morphed into, “okay, Taubes is wrong about thee things but so what?” Jack even made the argument that Taubes isn’t a rationalist so it’s unfair to hold him to that standard.
Not “unfair” just not relevant to whether or not he is essentially right.
I think people would react to your posts better if they included some of this at the top. You need to remind people why they should care

That’s a question of instrumental vs. epistemological help.
It works → instrumental. Here’s why it works ->epistemological.
Both are useful, and both are important for LW.

The core question is whether giving the person the dollar works as a strategy for raising my chances of going to heaven. Different churches might have huge disagreements about finding the real reason, but I don’t care that much about those reasons.
If you say that you don’t care about whether something is working, that’s declaring faith in the church of mainstream science, where adherence to virtues is more important than utility or consequences of actions. Is that really your position?
I care about whether or not something is working.
I’ve got this idea for a workout plan to increase your muscle mass: Buy these Magic Muscle Beans from me AND workout with weights 4 times per week for 6 months. You will experience tremendous results!
My point is that the Atkins Diet and every other Diet! basically combine common sense, well-established, mainstream health heuristics with magic.
Magic Beans and Heaven and The Perfect Diet! might exist, but my guess is they are superfluous, and used only to line the pockets of those who cite them as real.
Then don’t say that it’s irrelevant.
It’s very valuable to distinguish between whether something works and whether the theoretical underpinning is correct.
Usually there are years between the one and the other.
Einstein formulated the theory of special relativity decades before it had strong empirical evidence. That’s having theory before empirical confirmation.
Washing hands before operating a person is the other case. Even before you know about bacteria and viruses you should start washing your hands if you see that having clean hands generally reduce the number of complications in operations.
The people who advocate washing hands might tell you some magical theory about how washing hands means that you smell better and that your patients are less likely to develop complications because you smell better.
It’s a lot harder to find out that bacteria cause illnesses than to find out that surgeons who wash their hands achieve better results.
On the same token it’s easy to observe that many people who adopt a low carb diet, do lose weight on the diet. Whether it’s due to changes in insulin production, ketones-in-the-urine or some other factor is a harder question.
It’s certainly nice is someone is right about the reasons why the diet he advocates works but the person who’s suffering about overweight cares primarily about whether the diet works. A person who’s in the advice business is generally forgiven if his advice works but his theory is off.
As far from what I remember from school Michelson-Morley did show that not all was well with the prevailing physical model. I don’t think it provided enough evidence to validate that Einstein was completely right.
I think that for many people, getting fit (even if they arrived at fitness with incorrect justification) is far more important than spending time analyzing the theoretical underpinnings of fitness. Same thing with going to haven, choosing right cryo-preservation technique, learning to cook or any realm of human activity where we don’t learn theory
FOR THE SAKE OF BEING RIGHT, but we learn itFOR THE SAKE OF ACHIEVING X GOALS.I mean, I concur that having vastly incorrect map can result in problems (injuries during workout, ineffecting training routine, ending up in hell) but after you update a map a bit you hit the point of dimnishing returns, and it is probably better to focus on practical part than to theorize (especially in the realm of physical pursuits).
Um, yep. And that has been position all along on this series of posts. I’ve said why I think Atkins works and why I don’t think it has anything to do with why the Atkins diet is said to work.
Eat Less, Exercise More for weight loss.
Lift More for strength training.
Of course there are lots of exceptions, and plenty of nuance within these heuristics. But you said it best: The diminishing returns happen quickly for most people and most advice.
My point was only that if someone wants to sell you Magic Muscle Beans and a workout plan that says Lift More, don’t buy the beans.
The main problem with Taubes, I think, is that he fails to cleanly separate the two issues in question:
Why people have been getting more obese.
How to lose weight.
These are very different problems.
Why have people been gaining weight, on average? The reasons are complicated and Taubes gives important insights (even though, as OP said, his criticism of mainsteam nutrition is unfair).
How to lose weight, though, is a different matter. Every source I consult seems to agree that the reason the Atkins diet works is mainly because it makes it easier to eat less, by severely restricting the types of foods you can eat and also possibly reducing hunger pangs. I have yet to see any study consistent with the idea that a Atkins-type diet inherently makes you lose more weight than a conventional diet from mainstream nutritionists (if you match the number of consumed calories). I’d love to be proven wrong, but it seems that if Atkins works for you, other types of caloric restriction diets will also work, long-term.
Don’t expect it to generate any less controversy. I think it was Dennett who said that everyone thinks they’re experts on consciousness because it’s such a constant part of their lives, which makes it difficult for them to respect an expert philosopher on the topic. Well, everyone’s an expert on moving their bodies and stuffing food in their mouth and gaining or losing weight too. Giving them advice is a violation of their expertise, unless they’re looking for advice.
Gravity is also a part of everyone’s lives. Yet people respect Newton.
Very special conditions have to exist for conversion of time spent into greater correctness. These conditions do exist for physics or physiology, but they do not seem to exist for philosophy of consciousness.
I think respect was a poor choice of words to begin with. Perhaps people here don’t like Dennett, I don’t care much about him either.
If physicists tell laypeople something that contradicts their experience of gravity, like gravity affecting passage of time, some of them will have hard time accepting it. For laypeople, nutrition isn’t about physiology, and if their experience of weight loss for example contradicts expert advice, again they will have difficulty accepting it.
Change philosophy of consciousness to study of consciousness, and people would probably dismiss philosophers as well as neuroscientists if their findings didn’t fit their experience. I think many philosophers of consciousness cite neuroscientists, so their conditions are pretty special too.
Following his advice can result in chronic ketosis, read the article yourself to draw your conclusions.
Furthermore, there’s a wealth of contradictory data which he fails to report or distorts. For instance, Japanese eat high-carb low-fat diet (calories coming largely from white rice) and have very, very low prevalence of obesity, colon cancer, etc. Even more relevantly for Caucasians, obesity rates in Europe used to be very low fairly recently (and are still significantly lower than in the US), without being particularly low in carbohydrates—and the changes are very easily observable (fast food, soft drinks).
As for whenever his diets are effective for losing weight, that is a very complicated issue, largely psychological in nature. Perhaps some people can be more motivated when they follow unusual / non-mainstream advice, where success proves them right and their boring doctor (who recommends cutting fats) wrong.
edit: and as for whenever his advice would kill you… cancer risks associated with red meat are of interest.
