Im a 14 year old girl who is really thin and i wanna gain some weight so what should i do ?
Talk with your doctor before doing anything to gain more weight. Eating tons of junk food is a bad idea, this will only make you really tired and sick from all the crap in that kind of food.
you should do the simplest of them all.......eat JUNK FOOD!and always be proud of your weight no matter what
go see a doctor first of all who knows if you sick somehow so it's best to see a doctor before trying any weight-gain method.
eat but not too much calories:)
