Enter the basal metabolic rate (cals) into the Calculator. The calculator will evaluate the Thermic Effect of Feeding. 

Thermic Effect of Feeding Formula

TEF = BMR * .1


  • TEF is the Thermic Effect of Feeding (cals)
  • BMR is the basal metabolic rate (cals)

To calculate the Thermic Effect of Feeding, multiply the BMR (basal metabolic rate) by .1 (10%).

How to Calculate the Thermic Effect of Feeding?

The following steps outline how to calculate the Thermic Effect of Feeding.

  1. First, determine the basal metabolic rate (cals). 
  2. Next, gather the formula from above = TEF = BMR * .1.
  3. Finally, calculate the Thermic Effect of Feeding.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.
