..if i excercise for like 1.5 hours too.
Slowly and healthily is the best way. Incorporate a glass of 1% milk in, if you can, and check with a nutritionist to see which plan would be the best for you.
Just eat 2-3 meals a day, avoid snacking all together, unless it's fruit or something healthy. And when you eat, eat really slow. You'll find that you get full faster.
