Calorie Calculator
Estimate your daily calorie needs for weight loss, maintenance, or gain.
How the 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 represents the number of calories your body burns at rest to maintain basic life functions like breathing and circulation.
Your Total Daily Energy Expenditure (TDEE) is then calculated by multiplying your BMR by an activity factor that reflects your lifestyle. The calorie goals shown adjust your TDEE up or down to support weight loss or weight gain at a safe and sustainable rate.
