Step 1
Estimate the recommended individual caloric requirement (kcal per day) by calculating the REE.
For adult men:
	REE = 10 × weight (in kg) + 6.25 3 height (in cm) − 5 × age (in years) + 5
For adult women:
	REE = 10 × weight (in kg) + 6.25 3 height (in cm) − 5 × age (in years) − 161
Step 2
Multiply REE by an activity factor (AF) of 1.5 for women and 1.6 for men for light activity to estimate daily caloric need or by 1.6 for women and 1.7 for men for higher activity.
	REE × AF = estimated total caloric need (kcal per day) to maintain weight
