Okay, I am 6 feet 4 inches. I weigh 140 pounds, and my doctor told me im well underweight. he said i should be atleast 180 if not more. Im really skinny for some reason. i've been hitting the gym for a while, and eating alot of high protein foods. Can anyone give me tips on increasing body mass, and muscle with also gaining some weight?

Eat more!

This concept has been driving people crazy for years, it's so simple yet, so many people don't know this.

Here's the key to success:
However your much your eating right now, eat that much, but add 500 more calories worth of food.

(try for high protien pls)

I also tried eating every hour. still nothing. i've been doing this for like 3 months continously, and i've gained like 5-8 pounds:S

Fast metabolism. Get a gainer or protein would be my suggestion. I used to be just about your weight and height and ive put on 10 lbs or so.
