No do the opposite of this.
Why do you think body builders eat 6+ meals a day?
Last summer I made it my goal to put on some beef. ( I'm 6'2" and was 154 lb). I'm one of the skinny motherfuckers who can eat WHATEVER they want and do no exercise and still not put on an ounce.
I went to the gym 3 times a week and ate shitloads. 6+ meals a day, eating huge amounts, even when full to the brim with food. I was aiming for around 7000 calories a day and 150g protein.
Over two months I put on 7 kgs, and I sat at a more healthy 170lbs.
When university started again, I was back to no money for anything, (least of all 7000 calories per day). And I lost 19lbs in the space of 5 months.
Sparknotes:
Sucks to be an ectomorph (skinny guy)
Eat SHITLOADS and work out and you WILL put on weight.
But you need to be able to afford the food (I can't).
If you stop eating/gyming you will eventually waste back to your natural skinny frame.
