Detailed information about Calorie / BMR Calculation
The calorie calculator calculates basal metabolic rate (BMR) and total daily energy expenditure (TDEE) based on activity level using the Mifflin-St Jeor formula. To lose weight, it is generally aimed to be ~500 kcal below TDEE, and to gain weight, ~300-500 kcal above.
