I once weighed somewhere north of 320lbs (145kg), and eventually starved myself down to about 165lb (75kg) and kept it within 15lbs (7kg) of there for many years until COVID happened. I say this so you understand that I believe I speak from a place of authority when it comes to struggling with and losing weight. I think it is impossible for anyone who spent their life not having to pay attention to what they ate to maintain a "normal" BMI to understand precisely what it is like to not be that way. They look down on people like me because they think I must have gone out of my way to eat so much, when the truth is that I experience food in a completely different way from them. It's like I don't have an "off" signal for my compulsion to eat. I have to constantly pay attention to what I'm eating and try to ignore my hunger and non-hunger eating compulsion. Constantly. As in all the fucking time. It frequently makes me wish I were dead rather than have to put up with it. Frankly, I kinda hate people who don't struggle with this. Partially that's because those are the kind of people who made me feel like shit my entire life for being the way I am, and partially it is for making it look so easy that it trivializes my constant war with my own fucking body, but mostly I think it is envy. I have said many times, and I'm not sure it was entirely exaggeration, that would kill and eat such a person if I thought it might grant me their power to simply stop eating when they've had enough calories. I can tell you from experience that doctors and nutritionists don't know shit about this. And neither do you, random Hacker News about to promote a keto diet or intermittent fasting. Any diet will work for about 10lbs, I had to lose 15x that. There is a lot of bullshit science done on behalf of people selling food, selling diets, etc. making it pretty much impossible to separate useful information from marketing. I wish I could offer an answer. I have spent the past 15 years or so of my life constantly looking for one, to no avail. The best I've managed is that if I can put myself in a sufficiently manic state I no longer seem to have an appetite, but that's hardly viable.
