> If your body uses more energy than you eat, it must burn fat This is totally wrong. The body can also slow down your metabolism, twitch less, think slower (if you had read the article you'd see this is addressed), decrease the effectiveness of your organs, not to mention "eat" some of your nonfat muscle mass. The people advancing the CICO idea have obviously never struggled with their weight. It is super clear to me as a person who has bounced back and forth between fit to overweight for my entire adult life that there is nothing I could ever do to be as "skinny" as the skinny people I know, all of whom eat and drink way more than me, and usually don't exercise at all. CICO is not real advice, it's telling people to develop eating disorders, i.e. starve themselves. And for what? To bolster the ego of you and the ~60% of people who are naturally less likely to accumulate body fat, who like to believe they are just smarter or know something about nutrition that people like me don't. But it's exactly the opposite. I know more about nutrition than any of my skinny friends. Social pressure has demanded that I do so. It doesn't actually help, and the smugness of commenters on HN doesn't either.

Let's be fair here: you can be as skinny as them, it'll just be extremely hard and very unpleasant. I get where you're coming from though, it is difficult not to harbor an extreme amount of resentment for these people and the universe that didn't favor you in the same way. I have literally said to some people like this that, if I thought it would work, I would eat them to gain their power. For people like us, it is incredibly difficult to pull off. > CICO is not real advice, it's telling people to develop eating disorders, i.e. starve themselves. And for what?

  You lost 150lbs and might be in a somewhat decent health, but will it be true for that person over the internet that might have nothing in common with you ? The crux of these discussion on diet is that there is no universally reproductible method (CICO in isolation is just a principle and not a method) and starving he body will have different consequences for different people. Advocating any practice as “the only thing that matters” is a recipe for disaster. Imagine if the actual solution for that person is to change jobs, or that starvation lead them to worse health issues than where they are now, stuffing CICO down their throat would just be cruel.

    I find that to be unlikely, frankly. There are a lot of strategies to achieve a better CICO ratio, and I think those have incredibly varied success rates for different people, but when it comes right down to it if you don't find a way to change that ratio then you will never succeed. In my experience, the most expedient way to do it is to count calories. I also don't think this is anywhere near as "unhealthy" as people want to believe it is. I think that largely arises from our discomfort with being hungry, and our general intuition about which foods are "healthy" and which aren't. However, consider the case of nutrition professor Mark Haub, who ate nothing but garbage convenience store snacks for 10 weeks at a caloric deficit and not only lost 27lbs, but had all of his health metrics improve: http://www.cnn.com/2010/HEALTH/11/08/twinkie.diet.professor/index.html http://www.cnn.com/2010/HEALTH/11/08/twinkie.diet.professor/...

      Reducing overall stress is a pretty well known way to improve health, and it often leads to better diets/lower fat ratio one way or another. I don’t think it’s hard to find stories of people losing weight after getting out of shitty jobs/damaging relationships. Focusing on numbers (calorie counting etc.) can help people who like numbers and need to focus on something. But these people don’t need any push to go find numbers to follow. The same way I fundamentally like sport, I needed nobody’s advice to go do hours of sports when I felt my body was getting rusty.

> This is totally wrong. The body can also slow down your metabolism, twitch less, think slower (if you had read the article you'd see this is addressed), decrease the effectiveness of your organs But all of those factors are included under "body uses less energy", no? UPDATE: But I do understand what you're saying. Exercise can lower your BMR as the body tries to conserve energy. If that reduction is not met by a reduction in calories consumed, it stands to reason that you can actually gain weight after starting exercising. So gotta watch out for those lethargic days after lots of exercise. > not to mention "eat" some of your nonfat muscle mass. From my unscientific experience, for most people that should be accompanied by reduction in fat, too.

> The people advancing the CICO idea have obviously never struggled with their weight. > CICO is not real advice I used CICO effectively to reduce my weight considerably. Indeed it is not a real advice, however for me it was a very good guiding principle that I feel was essential to help me achieve my goals. By focusing on CICO it became clear that I had to find foods that I enjoyed eating and that made me feel fuller per calorie. I spent a fair bit of time thinking about meal compositions before starting due to this. I found ways to adapt my favorite dishes, both in portion size and ingredients. Using CICO I only had the goal that my meals had to fit my calorie budget, had to be enjoyable to eat and had to keep me full till the next meal. The principle also helped me stay on track, as it effectively means that it doesn't really matter what you do any given day, rather what you do each day. This made me avoid getting depressed and feeling hopless if I couldn't follow my plan for a day. My finish line got pushed ahead a day or two, no worries, just get back on track the next day. I think the key though is that people are different. What worked for me will not work for everyone. For me, CICO was great.

You are right that your body can burn muscle as well as fat. However, decreases to energy consumption ("metabolism") are minimal. Our bodies are evolved to use energy efficiently, if it were possible to do everything we do (or even some semblance of it), with far lower energy consumption, we'd already be doing it. A good analogy might be fuel consumption in a car. Some savings can be made through efficient driving techniques, but ultimately there is a core amount of energy needed to transport the car across a given distance.
