As far as genetics and weight are concerned, maybe the genetics are about why doesn't everyone get fat eating all that sugar and starch? That is probably genetics.

Genetics loads the gun, environment pulls the trigger. Most of us grew up eating lots of stuff that, combined with our genetics, made us fat. Some of us never had a chance since we were gestated in an mother that set up some of our epigenome to ensure we'd grow up fat. The epigenome can be influenced for generations.

It is all probably lots more complicated than people generally think about.
