A calorie is a unit of energy. Foods have certain calorie counts. This is the amount of energy
required for you to “burn off” the foods you eat. Your body burns off calories with different
types of physical activity.
The recommended daily calorie intake depends on your height, weight, and physical activity level.
Many experts recommend an average of 2,500 for men, 2,000 for women, and 1,800 for children ages
5–10. This is the amount of energy your body will need per day to be healthy and active. Pregnant
women should take in 2,500 calories per day in their third trimester.
Losing Weight
To lose weight, you must burn off more calories than you take in. This is best accomplished by
watching what you eat and getting regular exercise.
If you are considering losing weight, do so gradually. Most doctors recommend a target loss of
1–2 pounds per week. To lose one pound of fat, you must burn off 3,500 more calories than what
you eat. To lose one pound in a week, you would need to burn 500 extra calories per day.
