What Is a Calorie Calculator?
A calorie calculator estimates how many calories your body may need each day based on factors such as age, gender, height, weight and physical activity. It can be useful for understanding approximate calorie requirements for weight maintenance, weight loss or weight gain.
How Does This Calorie Calculator Work?
This calculator estimates your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation and then estimates daily energy requirements using your selected activity level.
- BMR: Estimated calories your body needs at rest.
- Maintenance calories: Estimated calories needed to maintain your current weight.
- Weight-loss calories: A moderate calorie reduction from estimated maintenance needs.
- Weight-gain calories: A moderate calorie increase above estimated maintenance needs.
