| >>"The idea that obesity could be avoided or cured with a little bookkeeping and self control" > It absolutely can. No it can't. ;) Well, not always. I've experienced both sides of this: an effortless loss of 60 lbs with easy diet changes and bookkeeping over the course of a year and a half. And a few years later, an abject failure as the same strategy -- a moderate calorie restriction -- resulted in such profound physical distress that I developed psychological problems long before I made any physical progress. Sometimes it's easy. Sometimes it's impossible. My story is far from atypical. It's common. Practically universal. Everyone, just about everyone, who tries to lose weight, using any strategy, succeeds over a period of months, and fails over a period of years. The reason is that the underlying control mechanism is in a different condition, in different people who may be the same weight. > people just don't want to feel bad about not having enough self control. I know you're really attached to the energy imbalance theory of obesity. People often are. But I'd like to suggest that this comment suggests you may have a different motivation for believing in it than just that you find the evidence persuasive. I often wonder why people get so attached to a theory that I think is in such obvious evidential crisis. A need to believe a simple solution will be there when they need it? A traumatic dieting experience that they need to believe was necessary and useful and healthy? Maybe it worked for them once and they're universalizing their experience? A desire for moral superiority? The fact that deliberately oversimplifying things makes for slam dunk messages on forums? I don't know, but diet is one of those weird topics where people are attached to their opinion with the religious fire of a thousand suns. While I know I won't change your mind, it does seem fair to point out that your statements are both hyperbolic and inaccurate, and that's not a good sign. |
It isn't a theory, it is a fact. It is basic thermodynamics. The human body requires a constant amount of energy for basic operation and activity. Any excess is stored as fat for future use. Creating fat requires calories that HAVE to come from food. Eat few enough calories and you WILL lose weight. Eat zero and you WILL die. Eat 20,000/day for a year and you WILL get very fat.
A good example of this is this man went 382 days without eating
https://www.diabetes.co.uk/blog/2018/02/story-angus-barbieri...
He had a calories surplus for long enough to weigh 207kg. While not eating his body consumed energy in his fat to stay alive and he got down to 81kg. ((207-87)kg * 7700 calories/kg)/382 days = 2539 calories/day, which is a very plausible number.
