Obesity is caused by overeating though, at the very least in the same sense that nearsightedness is caused by the wrong shape of the eye.
Energy intake > energy expenditure, but both intake and expenditure can vary for a variety of reasons uncorrelated with eating habits.
Sorry for being pedantic but I think that's what the above commentator meant.
> Energy intake > energy expenditure
Isn't that technically overeating though?
If someone ate the same three meals for 20 years and maintained a consistent weight, and then due to some physiological change started to put on weight eating the same amount, I'd find it reasonable but perhaps incorrect to attribute their weight gain to overeating. But yeah, technically at the end of the day, they could eat less :)
