it all depends on how much you trained your muscles... if you do sports now (or train your muscles in a fitness studio), you will most likely gain 5 kilos pretty fast without eating (much) more. if you already do a lot of sports, you might want to eat more :P

because 60 kilos for a well trained body is not enough at all, except you are a marathoner
Quite right. That was the only thing I can make of the info he gave though.
