Your Total Daily Energy Expenditure (TDEE) is an estimate of the number of calories you burn each day, including both your basic bodily functions and any physical activity. To calculate TDEE, you first need to determine your Basal Metabolic Rate (BMR), which represents the calories your body needs at rest to maintain vital functions like breathing and circulation.

​

The TDEE calculation involves multiplying your BMR by an activity factor that reflects your daily physical activity level. This adjustment is necessary because everyone burns additional calories through various activities, even if they lead a mostly sedentary life.

​

Our TDEE calculator utilizes the Mifflin-St Jeor formula to provide accurate and easy-to-understand results. By inputting your personal details, you can quickly see how many calories you need to maintain your current weight, as well as recommendations for weight loss or gain.
