The study was underweight bmi vs healthy bmi. Nothing about overweight bmi, which I would assume is the trifecta of overeating, little activity, and slower metabolism. At least that is my personal experience in going from overweight to healthy bmi. Really not surprising that people that eat less have lower bmi and higher metabolism than people that eat more with a slower metabolism but who are more active.

Hunger is mediated by a bunch of hormones and you can test for some of those, but there is no test for the feeling of hunger. As a comparison, it is famously very hard for doctors to understand pain; it is also difficult for patients to communicate about pain. The feeling of hunger is not comparable between people. Hunger is driven by multiple sensations (blood sugar, stomach stretch, hormone levels) and by cognitive…

You just restated what the OP said, but tried to paint it somehow in a more positive light. You yourself stated you are "eating fewer ... highly rewarding foods".

So what exactly are you contradicting in their statement?

Seems to line up with my experience, am always burning up (until I turn on the AC and freeze) Especially at night though I have to to jack the temperature down or I won't sleep. Also less hungry aligns pretty well. Unfortunately when I get hungry, it's normally "a little hungry) at akward spread out intervals. I probably feel most hungry after midnight but never eat then because well, I have to sleep soon. I've tried…

Same for me. Even as Ive tried to gain weight, my weight barely budged. 150-155 for at least the last 10 years. I have obese (300lb+) friends and they insist they don’t eat that much more than me. Except they do. We go out to eat, we stop eating after about 5-10 min. I’m full and done. They burp a couple times, then proceed to keep eating, smothering everything in Mayo and bbq sauce. Then they get insane desserts. An…

Overeating is the root of it. It's popular to deny this and come up with other excuses; normally when I'm with somebody making those excuses for themselves I don't dispute any of it (because it's not worth the social capital I'd expend in doing so.) But what really ticks me off is when somebody offers those lame excuses up for my obesity. I'm not big boned, there's not something wrong with my metabolism, I don't have a glandular disorder. They think they're doing me some sort of favor, telling me that my obesity is not my fault. But none of that stuff is true and encouraging me to lie to myself is cruel, not kind. I have a binge eating problem. It's that simple. If I examine my own diet with a dispassionate eye, it's obvious that I eat enough for two men and weigh as much as two men. There is no mystery to obesity, only ego-clouded judgement and denial.

I think the hungry bit is often under-discussed. I lost 75kg over 3 years, then put exactly 75kg back on over the 4 years after that. While losing weight, and keeping it off (for about 6 months), I was hungry all the time, every day. I hoped that my body would eventually "get used" to the new standard, but in the end (not conciously), I gave up -- it was too mentally tiring to be hungry whenever I was awake. I'm sure…

Your description of always feeling hungry after keeping it off is rather worrying to me, since I’m getting close to my target weight after a 1 year+ journey of diet and exercise.

I do remember reading before that the fat cells that get created when you gain weight never really go away, they just “deflate”. So after you lose weight, you are more likely to gain the weight back than someone who is at the same weight now but who has never been bigger than that.

I also recall seeing a study that your body sends you extra hunger pangs to gain the weight that you lost back, because it assumes that losing weight means you’re in fight-or-flight mode, so it wants to make sure you survive. That’s why a weight loss drug where an extra 300-400 calories per day were excreted via urine did not show significant results.

I couldn’t find the exact study for the second part. So I’ll just leave a general reference from Northwestern alluding to the same results.

I'm fat (I see no shame in this word), my partner is not - she and I will order the same food, I clean my plate (starving children in africa related childhood trauma, I guess), she will often eat half of hers and leave the rest - she drinks the regular soda, and I have water, diet soda or unsweet iced tea.

I can't speak to your friends, but there is no universal truth here - I know a bunch of fat people, and none of them 'drown them in bbq sauce and mayo' - most of the thin people in my life and fat people in my life end up eating 'around' the same amount of food, but the thin people are physically often much more active.

I think they’re saying that they eat equivalently rewarding foods that are more healthy.

That one word you elided, "stereotypically", was doing a lot of work! I'm not actually eating fewer highly rewarding-to-me foods, just less junk food, and I'm not constantly hungry.

Interesting. I stay thin because I'm always watching what I eat and keep a mental note of how many calories I've had that day. If I'm trying to lose a few pounds I have to actually record my calories so I know when to stop eating. I can eat pretty much non-stop. I could eat a large pizza myself, and 30 minutes later eat another. The grass is always greener. Some people wish they could eat as much as me so they could…

> I could eat a large pizza myself,

Sure you could. But do you actually do that often? If you eat like me, you're eating two large pizzas a night two or three times a week.

If you stay thin, I guarantee you don't eat as much as me. At least not unless you have an activity level comparable to an actively training Olympic athlete.
