Could Low Body Mass Be Due To Excessive Masturbation?

Hi.
I masterbate almost every day, and i don't have a very good food diet because i'm student in another country far from my family. Because of the diet i have i always have frightened to go gym. Because it'll take a lot of energy out of me!
I'm about 53 kg, and 23!!!
Do you think masterbating is the problem that i have to abandon?
What is the main problem?
I'm naturally skinny!
