18. Reaching and Appropriate Weight
The Energy Equation
Calories in (from food)
Calories out (from physical activity)
The secret to maintaining a healthful weight is to adjust your “energy equation.” The energy equation is the balance between “calories in” and “calories out.”
If you are underweight, you need to take in more calories from food than your body burns off.
If you are overweight, you need to burn more calories than you take in.
Balance

19. Reaching and Appropriate Weight
Females between the ages of 14 and 18 need approximately 1,800 to 2,400 calories each day depending on how active they are.
Males between the ages of 14 and 18 need approximately 2,200 to 3,200 calories each day depending on how active they are.
The MyPyramid food guidance system recommends that teens get approximately 60 minutes of physical activity per day on most days.
