TDEE (Total Daily Energy Expenditure) is the total amount of calories your body burns in a day, including all physical activities and vital functions.

BMR is the amount of calories your body burns at absolute rest, just to maintain vital functions such as breathing, circulation, and body temperature.

TDEE is calculated by multiplying your BMR by a physical activity factor that varies according to your daily exercise level.

Knowing your TDEE is essential for planning your diet, whether to lose weight, gain muscle mass, or maintain your current weight. It serves as the basis for determining your daily caloric needs.

To lose weight, consume fewer calories than your TDEE (caloric deficit). To gain mass, consume more calories (caloric surplus). To maintain weight, consume calories close to your TDEE.

The calculation is an estimate based on scientific formulas. Factors such as genetics, body composition, hormones, and others can influence the actual value. For greater accuracy, consider consulting a healthcare professional.
