everyone's body is different and depending on the amount of activity he did during highschool can be a big reason why. there's nothing wrong with a bro whos getting interested in putting on some mass and lifting weights whether he is a buck 10 or 300. id say hes better off then some of the big guys i knew in highschool, once they stopped playing sports but kept eating the same they got big and pudgy. he has the advantage of getting big and continuing to be healthy for the rest of his life.
keep lifting hard and eating as much healthy food as you can. get your protein in each of the meals you have and youll be ok. and drink lots of milk!
