my girlfriend is in the chubby range, like she has muffin top when she stands up and when she sits down it forms in to one large roll and one smaller one right on top on it. her father passed away when she was very young and he was very over weight and her mother is the same way. (250-270lbs) my girlfriends always was small and skinny and played sports but that was some years ago. now she has stopped sports and she didnt become over weight till she got in to 7th grade. when she is out she eats like she is watching her waist line but when shes home and her mom cooks, which in 70% of the time, she eats like her. adding tons of butter and oils and just eating a lot of food in general which explains why her mother is very overweight. so my question is what is the chances of her being bigger then her mom? shes 18, 5'8 and about 170lbs.
