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…

Check out /r/noburp.

I couldn't burp for most of my life until I taught myself.

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.

When I was 16, I was playing varsity basketball, baseball, track and was working on a farm doing heavy work all summer. Per the doctor, I was obese. My wife was obese because breasts. BMI is bullshit imo, it has some general value but creates a lot of distress for people, especially women.

BMI is pretty good for populations.

If you are standing in front of your doctor and he or she is telling you that you are obese because of your BMI score and not actually measuring you (like with calipers), I’d probably look for a new doctor.

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?

They are trying to convince everyone that the fruit & veg & lean meats is every bit as enjoyable as a steak and piece of cheesecake. It may be for them, but as a rule I have my doubts.

Yes, and, about 8 minutes of true HIIT* at least 3 days a week for 6 weeks is proven to adjust your metabolic run level. Graph your weight. After 6 weeks of HIIT, you'll see weight really shed because you're not burning calories during exercise but 24/7, and because of that metabolic shift, the weight will continue to shed for months even if you stop HIIT. * HIIT is High Intensity Interval Training. It's a technical…

HIIT is great for cardiovascular development, but be aware that this develops your carb oxidation, and doesn't do much for fat oxidation. So many health problems are tied to poor metabolic flexibility, where your body favors carbs over fat. You develop fat oxidation, and metabolic flexibility, with long endurance, low-intensity exercise. Pro cyclists racing every day in the Tour de France right now are going mostly on fat oxidation at incredible power levels. They got there with mostly low intensity training (but lots of it, and some degree of HIIT). Here is a timely publication that goes over variables tied to fat oxidation (and points out how intensity deactivates fat oxidation): https://link.springer.com/article/10.1007/s40279-022-01727-7

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…

The 'it's all my fault' attitude isn't really helpful for you to solve those problems however. Binge eating can be driven by a myriad of factors, mostly psychological. I'm fat too, and I'm comfortable with that word, I dont like medicalizing it with term obesity.

While my weight is at least partially my own fault, its at least influenced by factors outside of my control - upbringing, genetics, societal factors, and an endocrine disorder too. I've concluded that being fat is a result of Type II diabetes rather than a cause - and there is growing science to back me up - a good example of this, my liver dumps glucose into my system, without meds I can fast for a nearly indefinite period of time without my blood sugar falling off.

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…

Your using Satiety Index method. An excellent method.

There are some fruits and vegetables and lean meats (which absolutely includes "leaner cuts of steak with the fat trimmed off") that I quite sincerely like as much as junk food, if not more. Two pan-fried salmon fillets and a big bowl of brussels sprouts with butter beats the pants off even a pretty good burger-and-fries, the main downside being the prep (and, well, the cost for most people). A pound of fresh strawberries is damn good and not something I have to force myself to eat, etcera.

I don't deliberately avoid dessert, though I do tend to eat it less than I used to. I'll have the cheesecake if I really feel like it.

My sympathies to those who really just don't like any fruits or vegetables, but there are lots of other margins to operate on in lowering your dietary energy density. e.g., for a side with your steak, I assert most people will enjoy a baked potato with a bit of butter (~1 cal/gram) about as much as garlic bread (~3 to 4 cal/gram).

I've known very active cyclists that couldn't lose weight despite riding hundred mile rides weekly. In my youth, I could eat anything and do nothing and not suffer the consequences. I definitely fit the "run hot" part but I was the plate-cleaner in my family and didn't really stop eating like that until I was in my late 30s and suddenly started gaining weight.

> I've known very active cyclists that couldn't lose weight despite riding hundred mile rides weekly. Isn’t this against the laws of physics? If you’re burning a ton of energy and not eating excessively, where are their bodies getting mass from to maintain weight?

I think this is pretty common for people who exercise intensely. If you don’t increase your eating, you’re going to 1) feel hungry all the time and 2) negatively impact your performance. I trained for a marathon two years ago after only doing half marathons. I basically couldn’t lose weight unless I trained less.

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…

You don't say what your diet was, but "lots of raw vegetables" is not a formula for a sated appetite. Sure, if you eat enough of them you will eventually feel "full" for a while in a bloated sort of way, but fatty foods such as meat, eggs, and nuts will stop the "hungry" feeling without stuffing yourself. Or so it is for me.
