I am scared that my masturbation activity is making me skinny .. i want. to become healthy plesse can u suggest me my benefit ?

Doubt it: Masturbation is quite normal but when it is excessive it is not. Being skinny is also normal and there is no association.

Not the issue: The only way this would make you skinny is if you skip meals to do it. It is otherwise just a normal part of sexuality with no real impact on anything in your life. You have likely heard many myths about associated problems passes by a culture that discourages the practice.Skinny may be in your genes or from poor dietary habits/appetite.
