This is just on the top of my head, but since obesity is one of the leading causes of death, coupled with the stigma of getting into relationships with obese people, in the far future the genes somehow responsible for obesity would be gone. Those who would survive and pass on their genes are the normal or at most, overweight ones.

Natural selection like that only occurs if you die before you get a chance to reproduce, a lot of the diseases affecting the obese kill you a bit later than that

But to be fair, obesity does affect your chances of finding a mate.

Obesity is also linked to an increased chance of infertility in both men and women.
