Determine Resting Metabolic Rate (RMR)
Range for Men: 9-17
Range for Women: 8-16
---The higher the lean muscle mass the higher the number you use----
Multiply weight(pounds) by number in range--- 200lbs X 13 = 2600 calories RMR
Body Fat Method
- Find Percentage of Body Fat
- Find Fat Free Mass (FFM) by multiplying body weight by fat (decimal form) and subtract fat pounds from total body weight. Then divide by 2.2 to get FFM in kilograms.
EXAMPLE: 200 pound Male with 12% body fat:
- convert body fat to decimal = .12
- multiply body weight by fat = 200 X .12 = 24 lbs of fat.
- subtract fat weight from overall weight = 176 lbs FFM
- convert to kilograms = 176/2.2 = 80 kilograms
- RMR = 370 + (21.6 X 80)
- RMR = 2,098 calories
