Typically this is:

- 25 to 30 kcals/kg/day for normal, healthy individuals with little to no daily physical activity [11.5-13.5 kcal/pound]

- 30 to 35 kcal/kg/day for those involved in light to moderate activity 3-5 x a week with moderately active lifestyles [13.5-16 kcal/ pound]

- 35 to 40 kcals/kg/day for those involved in vigorous activity and highly active jobs [16-18 kcal/ pound].
