My wife was watching a T.V show called cook your self thin and on there they had a very interesting and simple to use way to know how many calories you should eat per day. Basically it is deciding on your ideal weight so lets say you wanted to weigh 150 LBS. You times your ideal weight by 10 and thats how many calories you should eat that day. So you'd want to eat no more than 1500 calories. Pretty simple and easy to remember when deciding how many calories to hit your ideal weight.
