Okay guys. I'm know I'm a guy. But I still wanna be slim >_<

I'm a disgusting weight and I REALLY want to lose 20 pounds ish. 

I'm going on holiday in May and I want to be slim for it.

I go to the gym everday and burn like 1000 calories and only take in like 1500 calories a day.

I have a low will power but I want to cut out certain foods and replace them with fruit or vege.

Any ideas?!

Love you xxxxxxxxxxx
