Obesity is almost never genetic. There are a tiny handful of genetic conditions for which obesity can emerge as a side effect, but in the vast majority of cases obesity is simply the result of consuming too many calories. [1] I don't think a source should be necessary for this, though I did bother to include one. Obesity hardly existed in e.g. the fifties, and that was certainly not for a shortage of food. And the individuals of healthy weight did reproduce, in great numbers. The sudden emergence of a massive genetic disorder makes no sense. On the other hand people started becoming fat once quick, cheap, food that sacrifices healthfulness for flavor and price became ubiquitous. And in contemporary times we've subsidized the pants off corn resulting in things like high fructose corn syrup being in practically everything. And of course it would be remiss to not consider the great changes in the engineering of foodstuffs and the corresponding change in the status quo of herbicides with us also consuming trace amounts in massive quantities, as a generational experiment.
