Interesting. I can't say I have read much on the genetics traits regarding obesity or know much about it.
I do know two female siblings, same parents, and they are both complete opposites with their weight. One tends to over eat when stressed, and the other has the opposite problem, lack of appetite.
No clue about the genetics, although the younger sister was raised eating much more fast food than the older sister, who had home cooked meals mostly before their parents had seperated.
I would have just blamed Mc Donalds.
