>It varies by person but is generally not a major effect. A few hundred calories is typical and is largely attributable to changes in NEAT. A few hundred calories is ~10-16% of the daily necessary caloric intake of many people, I daresay most? It is most certainly a major effect and considering that people become obese most often by consuming a small daily surplus, a few hundred calories extra, over many years, a swing of 100-300 calories can easily make the gaining weight much easier or much harder.

I wouldn’t consider 200ish calories “major”, in part because the typical weight loss plan includes a deficit of at least 500 calories/day, but mostly because it’s straightforward to turn a 500 calorie deficit into a 700 calorie deficit to accommodate the adaptation. Adaptation isn’t meaningless but it’s also not offsetting large deficits the way many people think it is. As for obesity happening due to 100-300 extra calories per day, yes, but also not really. If a person’s intake is 300 calories per day over what’s necessary to maintain a healthy weight, then they will put on weight until TDEE (which increases with body mass) catches up with their intake and they land somewhere above their healthy weight. It’s not an unbounded growth unless caloric intake is also growing continuously. I would imagine it’s quite common to see obese people eating 300 calories over their current TDEE but also to be 1300 calories over their healthy-weight TDEE. Also don’t forget that the 300 extra calories is after the metabolic adaptation from eating a surplus. So if an individual will increase TDEE by 200 calories in response to a surplus, then they’ll need to eat 500 calories above “real” TDEE to see a 300 calorie effective weight gain. All this is to say that obese people are generally eating quite a bit more than just 100-300 calories too much per day.
