Harris-Benedict Equation
The Harris-Benedict equation estimates your Basal Metabolic Rate (BMR) based on weight, height, and age. It is one of the most widely used and validated formulas for estimating energy expenditure in men.
Cunningham Equation
The Cunningham equation estimates your Resting Metabolic Rate (RMR) based on lean body mass (LBM). It is considered more accurate for active women and athletes because it accounts for muscle mass rather than just total body weight.
