What do you think of the concept of revenge body?

I recently had a breakup with my boyfriend and though he loved my body the way it was, it definitely could use some improvements.

The breakup is motivating me to almost starve myself because I can't hardly eat in this state and to also work out more.

I know I should be doing it for myself, but the next time he sees me, I want him to go damn, I may have made a mistake.
