About Calorie Calculator
This calculator uses the Mifflin-St Jeor Equation to estimate your Basal Metabolic Rate (BMR) and daily caloric needs based on your activity level. Your BMR represents the number of calories your body burns at rest to maintain vital functions.
Understanding Your Results
- BMR: The calories your body burns at complete rest
- Maintenance Calories: The calories needed to maintain your current weight based on activity level
- Weight Loss: Create a caloric deficit by eating fewer calories than maintenance
- Weight Gain: Create a caloric surplus by eating more calories than maintenance
