Hi

In order to gain weight, you need to start eating 5-6 meals a day. However, it is important that you break these meals into parts, as eating a lot at once may result in indigestion and your body may not be able to absorb all the calories. It may be possible that you won’t find yourself hungry 3 hours after eating lunch, but eat anyway and notice how your appetite increases from day to day. Also, be sure to include healthy High calories foods in your diet for a healthy weight gain.

Bodybuilding is a game which is totally depent on the calorie  intake of a body.

if iam talking about your case you Metabolism is fast so that if you want to increase your body mass then you have to intake more calories ( 60 % from cabs & 40 % from protein).

And also, you should take high calorie gainer with creatine monohydrate as a supplemet.
