Plenty of evidence.

Any that you find particularly clear and compelling?

Anyone have thoughts?

I was criticising the criticism of this post.

I feel like you're taking all of this way too seriously.

This answer has too many upvotes in my view.

I suspect it was here early in the discussion and people upvoted for whatever reason it is people upvote early comments.

Things you cannot control directly - what your metabolism actually does with the food you put in your mouth

Agreed. Some people have significantly higher metabolisms.

Things this model doesn't even mention - there are other important things about the food, not just calories

Agreed. I'm not talking about nutrition, just weight loss.

To the extent people yo-yo, I think the novelty wears off and old habits come back. You're often dealing with months or years of new diet versus decades of old habitual diet.

I mean you notice the differences more in the first phase of a diet. You may have some New Diet Energy! that gives you a boost and helps counter the differences.

After a while, you can get accustomed to less food.

Some random barely-edited thoughts on my experience with weight loss:

In the midst of a diet where I will lose 15 lbs (15.9lb, from 185.8 lb to 169.9, to be exact) in 40 days.

I have 95% certainty I will reach this goal in the appointed time. Even if I don't reach exactly 169.9lb, I'll be close, so whether or not I hit the exact number is arbitrary for my purposes. (I'm losing some weight to see if it helps a lingering back injury.)

I'm just eating a disciplined diet and working out according to a consistent schedule.

My diet is simple and not starvation-y at all. Most people wouldn't do it because it's repetitive (I literally eat the same thing nearly everyday so I can know my calorie intake without any counting.)

My workout isn't hard but most people wouldn't do it because...I don't know why, it's just my experience that people won't. It's 4-5 days per week of 30-60 minutes cardio and 30-60 minutes of weight training. I have a back injury that's limiting me, so it's nothing terribly rigorous.


In my years at health clubs, talking to health-club-going people, I've seen all the evidence I'll ever need to believe, basically, the Calories In / Calories Out model of weight loss is correct.

My opinion of the rationality community's view of weight loss is that it's bad. In fact, it is what I would consider anti-advice—the sort of thing you would introduce someone to if you wanted them to fail at weight loss. (Like in Mean Girls when Lindsey Lohan gives Rachel McAdams Swedish weight-gaining bars and tells her they are for weight loss.)


Some of my rough and random thoughts on managing weight:

  • Lean muscle mass is responsible for ~65% of individual differences in BMR.
  • People have significant differences in metabolism that are probably genetic predispositions. These differences can mean people who behave identically (same diet and exercise routine) will end up with very different weights.
  • No one should be shamed for their weight anymore than someone should be shamed for their height. (This is obvious, but needs to be said 'cuz "fat shaming" is an applause light used by the crowd who thinks anything resembling a simple CICO model for weight loss is bad and cruel.)
  • You shouldn't necessarily care about weight loss and our culture is fucked up for making people feel bad about their weight.
  • Losing weight can be really hard.
  • Diet is a central component to our lives, and changes in diet make people emotional, tired, etc.
  • Weight is a very personal issue and body image's importance in our culture, for better or worse, can not be overstated.
  • Exercising is a hard habit to adopt.
  • People lie. Self-reporting of diet and exercise is full of inaccuracies.
  • Changing your diet and exercise routine is akin to changing other habits and is subject to the same sorts of difficulties and failure modes.
  • The first 2-5 weeks of big diet changes are fucking hard, but it gets easier like any habit change.
  • Atkins, and other low carb diets, work because 'Murican diets are high calorie AND carb-centric. Cutting all carbs for a while means also cutting your total calories significantly. The published woo reasons why they work are mostly bullshit. It's just calorie cutting while giving you a shot at forming different long-term diet habits.
  • There may be some foods that speed metabolism, some foods that are good to eat at certain times during the day, some food that satiate more than others for any given person, etc...
  • But the Eat Less/Exercise More model is tried and true.
