How This Calorie Calculator Works

This calculator uses the Mifflin-St Jeor equation, which is considered the most accurate formula for estimating Basal Metabolic Rate (BMR). Your BMR is the number of calories your body burns at complete rest just to maintain basic life functions like breathing and circulation. Your Total Daily Energy Expenditure (TDEE) is calculated by multiplying your BMR by an activity factor.

The Mifflin-St Jeor Equation

Men: BMR = (10 x weight in kg) + (6.25 x height in cm) - (5 x age) + 5
Women: BMR = (10 x weight in kg) + (6.25 x height in cm) - (5 x age) - 161

Safe Weight Loss Guidelines

  • A deficit of 500 calories per day leads to approximately 1 pound of weight loss per week
  • Women should generally not consume fewer than 1,200 calories per day
  • Men should generally not consume fewer than 1,500 calories per day
  • Rapid weight loss can lead to muscle loss, nutritional deficiencies, and metabolic slowdown
  • Always consult a healthcare provider before starting a significant calorie restriction plan
