Calories are a measure of the energy you get from food and beverages. You will gain weight if you eat more calories than you use. You should lose weight if you eat fewer calories than you use. Below are tables that give the estimated number of calories needed each day. Look for your gender, age, and activity level. You should stay at your weight if you stick to this number. Note that this is an estimated number of calories.* Your exact number may be different.
