This on-line Total Daily Energy Expenditure (TDEE) calculator takes your gender, age, weight, height and physical activity level and calculates your daily calorie needs in kcal/day. This TDEE calculator will allow you to chose the BMR formula. You can choose the Mifflin St Jeor Equation formula or Harris-Benedict Equation.
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.
The PAL is determined by the lifestyle of an individual. The below table will give you and idea of PAL values for different lifestyle.
|Extremely Inactive||Person who is bedridden or bound in wheelchair.||Less than 1.40|
|Sedentary with No Exercise||An office worker, who do not have any option to move around and won't do any exercise.||Between 1.40 and 1.55|
|Sedentary with Little Exercise||An office worker, who moves around or will do little exercise every day.||Between 1.56 and 1.70|
|Moderately Active||Person who works by standing or doing moderate exercises like running or swimming for an hour every day.||Between 1.70 and 2.00|
