Understanding TDEE

Learn what Total Daily Energy Expenditure means, what influences it, and how to use a TDEE estimate responsibly.

What is TDEE?

Total Daily Energy Expenditure (TDEE) is an estimate of how many calories your body uses in a typical day. It combines your resting energy needs with movement, exercise and the energy used to digest food.

How TDEE is used

A TDEE estimate can provide a starting point for understanding maintenance calories. Real energy needs vary from person to person and can change over time, so treat the result as an estimate rather than an exact measurement.

What can affect TDEE?

  • Age, height, body weight and body composition
  • Daily movement and exercise
  • Work routine and lifestyle
  • Changes in body weight over time
