Total calorie requirement equation

BMR in calories + calories spend on activity

Estimate BMR equation

weight in pounds x 10 for women or 11 for men = BMR in calories

Estimate calories according to usual activity level equation

BMR in calories x 20% sedentary, 30% light activity, 40% moderate activity, 50% high activity = calories spent on activity
