Being aware of how many calories you're eating definitely will help. Just make sure your calories consist of lean protein (skinless chicken breast, fish, ground turkey breast, egg whites, very lean beef or bison), plenty of veggies (without toppings), and a couple pieces of fruit per day. Watch your starchy carbs - breads, potatoes, pasta. Try to limit them to early in the day, and stay away from anything that's not whole grain. Eating 5 or 6 small meals daily is better than 3 large ones - just divide your daily calories by 5 or 6. There are numerous calculators online that will help you figure out how many calories you should be eating based on your weight, height, activity level... If you really want to change your body, say good-bye (at least for now) to sweets, processed foods, soda, white breads and pastas.
It really is so worth it to put quality foods into your body. I've been eating "clean" for almost a year, and I have never felt or looked better. I've been counting my calories for quite awhile, but it never did any good until I changed what the calories were made of.
