Eating the Right Number of Calories (2005 Guidelines)

Calories are a measure of the energy you get from food. If you eat more calories than you use, you will gain weight. If you eat fewer calories than you use, you will lose weight. Below are the estimated number of calories needed each day for different genders, ages, and energy levels.* This is the approximate number of calories you use each day, so eating this number should mean you neither gain nor lose weight.
