Note: Values depict amounts of calories needed to maintain calorie balance for various gender and age groups at three different levels of
physical activity. The estimates are rounded to the nearest 200 calories. An individual’s calorie needs may be higher or lower than these
average estimates.

*Based on estimated energy requirements (EER) equations, using reference heights (average) and reference weights (healthy) for each
age–gender group. For children and adolescents, reference height and weight vary. For adults, the reference man is 5 ft 10 in tall and
weighs 154 pounds. The reference woman is 5 ft 4 in tall and weighs 126 pounds. EER equations are from the Institute of Medicine. (2002).

†Sedentary means a lifestyle that includes only the light physical activity associated with typical day-to-day life. Moderately active means a
lifestyle that includes physical activity equivalent to walking about 1.5 to 3 miles per day at 3 to 4 miles per hour, in addition to the light
physical activity associated with typical day-to-day life. Active means a lifestyle that includes physical activity equivalent to walking more
than 3 miles per day at 3 to 4 miles per hour, in addition to the light physical activity associated with typical day-to-day life.

‡Estimates for females do not include women who are pregnant or breastfeeding.
