Self loathing.

You do not deserve to eat to excess. You deserve the discomfort of eternally unfulfilled hunger.

You deserve the pain of exercise, and the struggle of lifting weights, and the only thing you can look forward to, if you get comfortable with the current weight you're lifting, is adding more weight.

I can't recommend it though as the cons far outweigh the pros.

Lifting weights though, do it, but start slowly to develop technique without risking injury. Make a habit of it.
