Eat you largest meal at breakfast, then lunch and smallest for dinner. Eat breakfast like a king, lunch like a prince, and dinner like a pauper.Try to eat dinner by 6pm. Weigh yourself every day, so if you get off track you'll know why. If you haven't started an exercise program already I would wait until you get to your ideal weight first, then up the calorie intake to maintain that weight, then start your exercise program. Most people stop exercising in the 1st 90 days, that coupled with dieting more than doubles your failure rate odds!
My belief is Diet + Exercise = Failure Consult your Doctor!
Exercise once ideal weight has been reached can help maintain that weight.
