No carbonated drinks, no sweets, no eating after 7-8 pm + some workout.

Yeah. I don't eat most days, so that's why. YOU DEFINITELY NEED TO EAT.

I'm a skinny guy.

I eat a lot of junk, but I have a high metabolism. I also workout, occasionally... Mostly to gain more muscle, and I have abs too, I'd like to keep that ;)

Continue to eat right and exercise ♥
