If your objective is to try and provide people with the lowest hanging heuristic for how to avoid unwanted weight gain, avoiding high fat foods is a pretty good candidate, since fat has the highest caloric content per gram (9) when compared to protiens and carbs (4). This appears to be the traditional view that the crazy government is trying to shove down our throats, so to speak.
Along come the carb-cutting people. My hypothesis is that the general rationale for this movement was the recognition that the average American diet was made up of some huge % of carbs (>50% of caloric intake) and so the simple math of avoiding carbs, even if you upped your fat intake, would ensure your daily average caloric intake went down.
Over time, even a relatively small difference in daily average caloric intake can make a relatively large difference in your body weight. For example, a 100 cals/day decrease will yield a ~10lb body mass decrease per yer.
Atkins, the flagship of the carb-cutting movement, advocates an extremely significant decrease in carbs, especially at the outset of the diet. It is zero wonder (to me) as to why it “works” for people. If you basically eliminate carbs from your diet, you’ll have to come up with creative way to even find ways to equal your former carb-including diet. You’re gonna lose weight pretty fast if you stick to the diet. (duh)
Cutting curbs does not preclude the logic of the crazy goverment’s advice to avoid fatty foods. Though there may be some physiological benefits to either low-carb or low-fat diets, in terms of overall weight loss, the primary mechanism is the same: calorie control. This isn’t a situation where one is (anything but marginally) better than the other.
We might expect Dr. Atkins, and every other diet-movement guy out there, to try and spin their particular brand of weight loss strategy as something unique and magical. In fact, it seems the existence of the economics of the self-help universe along with the difficult challenge of losing weight (or staying happy or having a good romantic relationship or being successful in your career, etc.) pretty much guarantees that people are gonna keep coming up with new ways of saying the same thing: Eat less calories (or any of the other basic level advice that leads to the other topics of interest often tackled by the self-help universe), and then putting a picture of themselves wearing a big smile and a lab coat on the cover of their book/website, and pretending to have discovered a Revolution in Weight Loss! that turn all the old-fashioned conventional wisdom on its head.
Over time, even a relatively small difference in daily average caloric intake can make a relatively large difference in your body weight. For example, a 100 cals/day decrease will yield a ~10lb body mass decrease per yer.
While that is widely claimed, it is false. Think about it for a minute: do you really think that a decade of such deprivation would kill a light person? The problem is not all the complications of metabolism that people bring up in these posts, but the very basic fact that energy consumption is roughly proportional to body mass. Under that model, a caloric deficit will not lead to linear weight loss nor a surplus to linear weight gain. Instead, the new caloric intake is enough to support a new weight and the difference between the current and new weight decays exponentially. Here is a recent model, with some testing; one of the authors is quoted claiming that a 100 Cal/day deficit will lead to a total loss of 10lb, after about 3 years.
Thanks for this. It is the first substantive comment I’ve seen.
I read the NYT article; the other is above my head. Frankly, I don’t buy this: “Interestingly, we also found that the fatter you get, the easier it is to gain weight. An extra 10 calories a day puts more weight onto an obese person than on a thinner one.”
I think they are observing (primarily) genetically slow metabolisms.
I’d agree that the 3500 calorie = 1lb of weight loss is not linear because 100 pound people don’t disappear in 10 years. Conventional wisdom says that metabolism will adjust to a 100 cal deficit so that one would need to reduce cals more with time In order to achieve the same result. OR they would need to add exercise, which is also conventional wisdom.
Would you agree that this: “An extra 10 calories a day puts more weight onto an obese person than on a thinner one.” is because they are looking at people with genetic abnormalities?
genetic abnormalities implies it’s not a giant fraction of the population. I think it’s very likely that either because of historic population genetics or possibly gut flora biomes that different people simply will gain different amounts of weight from the same food over the course of their lives.
Downvoted. You understood what was meant, yet chose to ‘win the argument’ instead of helping correct the wording to make it easier for others to understand.
Example of proper clarification:
“Over time, consuming fewer calories than you burn can make a relatively large difference in your body weight. For example, consuming 100 cals/day less than you burn will yield a ~10 lb body mass decrease per year.”
And yes, this is quite sufficient to kill most people within ten years.
Why is “per gram” the relevant metric? It should be something more like “per unit ‘satiating power’” (to the extent that such a thing can be defined). If drinking a half-litre bottle of Coke doesn’t make me less hungry than before¹ but eating a cone of ice cream makes me feel full, if I want to reduce my calorie intake it makes more sense to forgo the former even if it weighs several times as much.
Other than due to the water, CO2, and caffeine, which I could also get from a bottle of sparkling water and a shot of espresso.
That makes sense. I think calories per gram is a reasonably good metric, but there are probably much better ones.
I think the principle still holds: low fat or low carb diets work (when they do) because it is a simple way to help a consumer modify their diet using the lowest hanging fruit based on some reasonable logic (i.e. cut fat ‘cuz generally high calories, or cut carbs cuz’ Americans generally eat lots of them). You don’t have to think about it, and once you form the habit, it’s relatively easy to stick to.

This appears to be the traditional view that the crazy government is trying to shove down our throats, so to speak.
As a historical claim, I believe that this is false. The opposition to consuming fat is primarily about correlation with heart disease. Certainly none of the examples of government advice in this post are about weight loss.

They wrote down their reasons and this certainly isn’t any of reasons that Atkins gives.

Seems to me that this strategy is vulnerable to munchkinism (haha) by the food industry. Which sells “low fat” this and “reduced fat” that. Although fat content used to be a pretty good proxy for unhealthy food, it may be only a proxy.
What’s unhealthy about ice cream (assuming you’re not lactose-intolerant)?
Basically it tastes too good. There is something about foods which taste really good which (for many people) messes up their internal system for eating urges. This is my lay conclusion, resulting from nearly 2 years of informal research into obesity and diet.

This assumes that the average person can meaningful succeed in his attempt to eat less and beat his hunger. What people eat has a lot to do with the desires of the body for food and if you starve a body of fat that has consequences.
If you look at a modern home you can see that the surface area of heating equipment is important for a warm home. You could run and tell people who want warmer homes to increase that surface area.
In reality a much better advice is to turn the thermostat. You can be right about some parts but still miss the point.
There are multiple ways you can theoretically approach weight loss.
I think that calorie control is a center piece of the mainstream view.
As far as I can see preaching calorie control is not effective.
Gary Taubes focuses on reducing eating carbohydrates that raise insulin.
Another approach would be Seth Roberts set point frame. If you follow it than you give people nose clips and let them drink a bit of oil.
There are people who practice hypnosis who also operate on the set point model.
There are people who tell you that the key is about starting to listen to your body and perceive signals from it that most people ignore.
There seems to be an anti-pattern for certain kinds of problems that involve one’s habits, lifestyle, or emotions. The anti-pattern is that many people who do not experience the problem claim that the problem is easily solvable; whereas many people who do experience the problem claim that it is not easily solved.
People who have previously experienced the problem may fall into either category; whether they do seems to have something to do with how much continuity (or compassion?) they feel between their current self and their problem-having past self; or whether they have retained awareness of the specific transitions involved in solving the problem. (Kinda like some of the difficulties moridinamael recently pointed out regarding programming tutorials. Just because you’ve achieved X does not automatically make you a good guide for others who want to achieve X.)
This seems related to one of the things that folks who use the word “privilege” mean by it sometimes. We can probably come up with some less politically charged word for this specific anti-pattern, though.
Good point. It seems pretty common for people who study social phenomena — even heavily moralized ones, like crime — to have more compassion for the people involved in them than the “conventional wisdom” does.
Dunno if it’s not mainstream enough for you, but FWIW as of now the average rating of The Hacker’s Diet on Goodreads is 3.85 out of 5.
I don’t think that the Hacker”s diet is a mainstream work. It”s not written by a nutrition professor or by a government health agency but by a tech CEO.
the average rating of The Hacker’s Diet on Goodreads is 3.85 out of 5.
I don’t think that says much. The number also happens to be lower than Gary Taubnes Good Calories, Bad Calories.
As far as the Hackers diet itself goes, it preaches to measure weight with moving averages and make decisions based on that measurement.
As far as I know you can’t even buy a scale that does moving averages automatically that’s how non-mainstream the recommendations of the hackers diet happens to be.
I think if you ask most mainstream health folks what they think about moving averages for weight measurements they have no idea what you are talking about.
In a world where studies indicate that people who weight themselves daily lose more weight, a lot of mainstream health advice recommends against daily weighting to avoid negative emotions associated with seeing your weight.
I see nobody funding a study to see whether a scale that measures someone weight and then gives them the moving average performs against a scale that just tells people their weight directly.
Mainstream nutrition researchers focus to much on food to investigate theories like that.
However I don’t see in the page that you linked that Withings can be setup in a way that it never tells you your weight at a particular point in time but only displays the moving average when you step on it.
I would add that once you get rid of the idea that the body scale should display directly what it measures, you can also do things like menstrual cycle controlled weight for woman.
You could also think about simply display the difference between your weight and preset target wait for a particular day. There are plenty of different possibilities to display that information and in a sane world we would compare those difference and run studies to see which way of displaying the information actually encourages humans to make decisions that move them towards their target weight.
That’s an awfully specific use mode you ask for. A common mode of use of these scales, which I think is a better choice, is not to look at the display at all, perhaps even covering it. Collecting data should be a habit separate from analyzing data. And when you do analyze data, you don’t just want the current point estimate, but the graph of history.
Collecting data should be a habit separate from analyzing data.
You might be right or you might be wrong. In a sane world someone would run a study to give us data to answer that question.
But we don’t live in a sane world. Our mainstream nutrition researchers are not interested in answering that question. They rather fund huge studies that gather self reported eating reports and try to interpret those self reported eating reports to tell us that we should eat certain food over other food.
That’s an awfully specific use mode you ask for.
I’m asking a companies who are in the business of scale production to think about optimal data presentation.
I would want a company like Withings to either make the display fully programmable. Furthermore I would want them to run a study about which way of displaying data is best.
Scientific trial setup:
2000 trial Withings. They get sold with a rabate. Each user who gets them agrees to the trial and that the weight data of the trial is allowed to be published afterwards anonymously.
There are 10 different scales modes. In the first two years of using the scale the user will be logged into the scale mode that supposed to be tested.
After a year is up you go and analyse the data. Which information display was best suited for helping people lose weight? You go and publish that information in a good journal.
Then you go and tell newspaper journalists about your new study which shows that measuring weight in a certain way helps people lose weight. Coincidentally the way to have a scale that displays weight that way you have to go out and by a Withings.
That story is good in the sense that newspaper journalists would probably be happy to write about it.
I would even do a bit of the PR work myself when I do the next QS media interview (I have done >10 in the past).
I would add that once you get rid of the idea that the body scale should display directly what it measures, you can also do things like menstrual cycle controlled weight for woman.
(Another idea along those lines I once had was controlling for days of the week, as many people eat more on weekends than on weekdays. But the more parameters the model has the more likely overfitting becomes.)
Another idea along those lines I once had was controlling for days of the week, as many people eat more on weekends than on weekdays.
If you make 7 day rolling averages you already remove that effect. In any case from the weight charts that I personally looked at that effect doesn’t seem that big. Day to day changes in water content seem to produce more noise.
If one wants to get simplistic, saying “calorie control” is horribly wrong as a first approximation.
It’s calories versus metabolism. That at least recognizes a trade off, instead of picturing calorie control as a single unopposed knob to tune your weight.

This appears to be the traditional view that the crazy government is trying to shove down our throats, so to speak.
This doesn’t explain why the government put starches at the bottom of the pyramid, thus encouraging people to eat as many of them as possible.
If you follow the food pyramid your combined vegetable and fruits should almost equal your starch consumption. Thats not “as much starch as possible.”
For dinner, a 4 oz steak, 6 asparagus spears, a cup of rice and a beer, with an orange for dessert fits the food pyramid and with the exception of the beer, would probably be something paleo people would also eat.
Ok, replace “as many of them as possible” with “a lot of them”, my point still stands.
A lot is relative- one more serving of starch a day then your combined fruit and vegetable servings. I know paleos that eat enough rice to be (inadvertently) eating the food pyramid recommendations.

And pointing out that if this were the motivation, they wouldn’t have put starches at the bottom.
Why not? The pyramid says basically “avoid added fats and sugars”, and then suggests a diet thats 4 servings of meat and cheese, 5 servings of fruit and vegetables and six servings of starches.
If their motivation for telling people to avoid fats was simple that fats are highly caloric, one would expect them to not tell people that they should eat a lot of starch, which by the way was up to 11 servings (not just 6 servings).
Well, a large fraction of the grains grown in the US is fed to livestock, so you’d have to be thinking about something more specific than “grain farmers”.
I concur.

Hunger. Jojo dieting is a huge failure mode.
The German word “jo-jo” corresponds to the English word “yo-yo.”
Thanks. Those words that sound the same way but are spelled differently lend themselves to mistakes.
This is the crux of it: If you wanna weigh less, you gotta eat less.
Tell a person who”s 1.60 meter tall and who wants to be taller: If you want to be taller you need to grow more.
But there are adults who’ve lost a sizeable fraction of their body weight without any surgery, whereas hardly anybody grows taller.
Oh my god.
As I’ve said, losing weight is much more complex than just eating less… but the center of the issue is calorie control.
This is an issue where I think LW has collectively lost its mind.
Mainstream health advice with is centered around that maxim has failed to provide people who want to lose weight with a way that performs well.
What kind of evidence makes you think that a nutrition strategy should be centered around that maxim?
You’ll have to restate this.
If you look at a modern home you can see that the surface area of heating equipment is important for a warm home. You could run and tell people who want warmer homes to increase that surface area.

I don’t think that personal experience with the problem of wanting to lose weight is the only factor.
This is also a tribal conflict of academia vs. internet wisdom.
Stop eating so much carbohydrates isn’t much more complex than, saying eat less calories.

Do you have a particular explanation in mind for why they did?
Well, one explanation I’ve heard blames the farm lobby.
It does look like they are quite powerful, but OTOH it’s not obvious to me why people eating grains benefit farmers more than people eating meat.
The farm lobby might not include all farmers equally—grain farmers might have more of an edge.
Well, a large fraction of the grains grown in the US is fed to livestock, so you’d have to be thinking about something more specific than “grain farmers”.
