You're confusing genetics with laziness. No one ever said that given
enough dedication almost everyone can lose weight and keep it off. I'm
living proof.

It may be semantics, but I think it is counter-productive to call it
predisposition to obesity, because that way it is used as an excuse. "I
have a slow metabolism and thus need to work harder" is a better phrase.
