12lbs down in 8 weeks!!!

Snair4

I was never too fat to begin with, I started off at 127 lbs on Jan.1,2014 and ever since then, I have lost 12 lbs(115lbs now). I eat whatever I want as long as it adds up to1200 calories (with cheat days). I workout, mostly cardio, at least 5 times a week. I have gone down 2 pant sizes so I know I'm not losing much muscle because I casually lift weights here and there. i'm wondering for those who shed fat off their stomach, what exercises/weight training did you do? And how often? I really want to tone my stomach!!
