Here are some ideas for you.
1) Drink a full glass of water (or something like Crystal Lite) BEFORE each meal -- this helps fill you up so you don't eat as much.
2) Split your meals up so you have five meals per day -- breakfast, lunch, afternoon snack, dinner, evening snack/dessert
3) Have a small green salad with lunch and a larger salad with dinner (also helps fill you up) Use fat free dressing (I like Kraft Free 1000 Island.
4) Make sure you get plenty of fruits and veggies.
5) Your dairy should be fat free - skim milk, fat free cheese etc. "I Can't Believe it's Not Butter" is a good substitute for butter.
6) Eat whole grain foods -- such as whole grain wheat bread, whole grain brown rice etc. Much better for you than processed white bread and white rice.
7) Drink at least 64 oz of water per day (8 glasses)
Good luck guys
