Basal Metabolic Rate Calculator

BMR is short for Basal Metabolic Rate Your Basal Metabolic Rate is the number of calories required to keep your body functioning at rest, also known as your metabolism.

Harris-Benedict Formula

Once you’ve calculated your BMR, this is then put into the Harris-Benedict Formula, which calculates your total calorie intake required to maintain your current weight. This is as follows:

• Little/no exercise: BMR * 1.2 = Total Calorie Need
• Light exercise: BMR * 1.375 = Total Calorie Need
• Moderate exercise (3-5 days/wk): BMR * 1.55 = Total Calorie Need
• Very active (6-7 days/wk): BMR * 1.725 = Total Calorie Need
• Extra active (very active & physical job): BMR * 1.9 = Total Calorie Need
