Revised World Health Organization equations for estimating energy expenditure

Step 1: Estimate basal metabolic rate
Men 18 to 30 years = (0.0630 x actual weight in kg + 2.8957) x 240 kcal/day
Men 31 to 60 years = (0.0484 x actual weight in kg + 3.6534) x 240 kcal/day
Women 18 to 30 years = (0.0621 x actual weight in kg + 2.0357) x 240 kcal/day
Women 31 to 60 years = (0.0342 x actual weight in kg + 3.5377) x 240 kcal/day
Step 2: Determine activity factor
Activity level	Activity factor
Low (sedentary)	1.3
Intermediate (some regular exercise)	1.5
High (regular activity or demanding job)	1.7
Step 3: Estimate total energy expenditure
Total energy expenditure = Basal metabolic rate x activity factor
