How can i gain weight quickly but not get over sized or get big from just my stomach ?

Controlling fat: If i knew how to control where fat decides to go, i'd be a very wealthy person. Fat usually distributes itself according to a genetic predisposition. Gain weight by eating healthy protein/wt gain smoothies or shakes in between meals, and slowly take in more volume with each meal. Doing anything quickly is not a good idea--unless it is quitting smoking!
