What is a TDEE?

he TDEE is a rough estimate of the energy (in calories) that your body requires for you to function on a typical day. In most of us, that's about 50 to 80 calories an hour, which adds up to about 1,200 to 1,920 calories per day.

If you rested and never exercised all day long, you would still burn your total TDEE, which accounts for about 70 percent of total calories burned daily.

Your individual TDEE is influenced by such factors as age, weight, height, medical conditions, genetics and muscle mass.
