I don't see how there isn't a genetic factor. I mean, humans have known for centuries that if you take beefier animals and breed them together, you will often get beefier offspring.
Having said that, I do think that many people with a genetic disposition to being "fat" can in fact be thin and healthy but they might need to work harder for it than people without those genes.
