You're probably getting downvoted for the first phrase - there does seem to be some genetic component, albeit it's not clear how important it really is.
I agree with everything else you said.
- rubashov 15y agoThe genetic component has to do with susceptibility to overeating, though. It's not some magic "metabolism" setting as is most commonly claimed.
- dredmorbius 15y agoThere are probably several dimensions to this. Appetite regulation would be one, but that wouldn't explain studies in which food intake is strictly controlled. Metabolism regulation, insulin/glucagon regulation, intestinal flora, digestive efficiency, and other factors would certainly affect overall body mass. And issues such as thyroid function do directly affect metabolism.
