These estimates are based on estimated energy requirements (EER) equations, using reference heights (average) and reference weights (healthy) for each sex and age-group[1]. For children and adolescents, reference height and weight vary. The estimates are rounded to the nearest 200 calories. An individual's energy needs may be higher or lower than these average estimates.
* Sedentary means a lifestyle that includes only the light physical activity associated with typical day-to-day life.
¶ Moderately active is means a lifestyle that includes physical activity equivalent to walking approximately 120 min at a rate of 2.5 miles per hour or equivalent energy expenditure in other activities, in addition to that described for the sedentary level. This is equivalent to the "low active" category in the Dietary Reference Intake analysis[1].
Δ Active means a lifestyle that includes physical activity equivalent to walking at least 230 min at a rate of 2.5 miles per hour or equivalent energy expenditure in other activities, in addition to that described for the sedentary level.
◊ Data published in 2014 suggest that estimates for energy requirements of active preschool-aged children are too high. This is because new data suggest that physical activity levels for this age group are narrower than previously thought[2].
