EQUATION
1.) Mufflin Equation for Resting Metabolic Rate (RMR)
The Mufflin Equation for RMR (in kcal/day):
Note: Weight is in kg, height is in cm, age is in year.
2.) Activity calories Equation using METs Table
METs is calculated by getting the average speed over 10 seconds and looking up in the METs table for the
relevant METs value. (Refer to below table for METs reference)
