## TDEE (Total Daily Energy Expenditure) / Daily Calorie Needs

TDEE is the measurement of the energy consumed by the human body with physical activities. TDEE is calculated based on the BMR of the body and the physical activity level. You can read and know more about BMR (Basal Metabolic Rate) here. Once the BMR is calculated, it will be multiplied with the physical activity level (PAL) constant to derive the TDEE.

### Formula

TDEE = BMR × PAL

Where:

• BMR = Basal Metabolic Rate
• PAL = physical activity level of an individual. It is determined by the lifestyle of an individual. The below table will give you an idea of PAL values for different lifestyle.

### Physical Activity Levels (PAL)

Lifestyle Category Description PAL

With TDEE you can determine the calories or energy needed to maintain your current weight and also the calorie required to reduce or increase your weight.
