aTaken from new data on male and female median body mass index and height-for-age data from the Centers for Disease Control and Prevention National Center for Health Statistics Growth Charts (Kuczmarski, et al., 2000).
bCalculated from CDC/NCHS Growth Charts (Kuczmarski et al., 2000); median body mass index and median height for ages 4 through 19 years.
cSubtract 10 kcal/day for males and 7 kcal/day for females for each year of age above 19 years.

aFor each year below 30, add 7 kcal/day for women and 10 kcal/day for men.  For each year above 30, subtract 7 kcal/day for women and 10kcal/day for men.
bPhysical activity level.
cDerive from the following regression equations based on doubly labeled water data:
Adult man:  EER=661.8-9.53xAge (y)xPAx(15.91xWt [kg]+539.6xHt[m]
Adult woman EER=354.1 – 6.91xAge(y)xPAx(9.36xWt [kg] + 726xHt [m])
Where PA refers to coefficient for Physical Activity Levels (PAL)
PAL=total energy expenditure + basal energy expenditure.
PA=1.0 if PAL >1.0 < 1.4 (sedentary).
PA=1.12 if PAL > 1.4<1.6 (low active).
PA=1.27 if PAL > 1.6<1.9 (active).
PA=1.45 if PAL > 1.9 < 2.5 (very active).

ESTIMATED CALORIE REQUIREMENTS (IN KILOCALORIES) FOR EACH GENDER AND AGE GROUP AT THREE LEVELS OF PHYSICAL ACTIVITY(1)a

Estimated amounts of calories needed to maintain energy balance for various gender and age groups at three different levels of physical activity. The estimates are rounded to the nearest 200 calories and were determined using the Institute of Medicine equation.

a These levels are based on Estimated Energy Requirements (EER) from the Institute of Medicine Dietary Reference Intakes macronutrients report, 2002, calculated by gender, age, and activity level for reference-sized individuals. "Reference size," as determined by IOM, is based on median height and weight for ages up to age 18 years of age and median height and weight for that height to give a BMI of 21.5 for adult females and 22.5 for adult males.
b Sedentary means a lifestyle that includes only the light physical activity associated with typical day-to-day life.
c 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
d 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.
e The calorie ranges shown are to accommodate needs of different ages within the group. For children and adolescents, more calories are needed at older ages. For adults, fewer calories are needed at older ages.
