Calculate Thermic Effect of Feeding (TEF)

Formula

The formula to calculate the thermic effect of feeding is:

\[ \text{TEF} = \text{BMR} \times 0.1 \]

Where:

What is Thermic Effect of Feeding (TEF)?

The thermic effect of feeding (TEF) refers to the amount of energy expended by the body to digest, absorb, and process nutrients from food. It is typically about 10% of the basal metabolic rate (BMR), which is the number of calories your body needs to maintain basic physiological functions at rest.

Example Calculation

Let's consider an example:

Using the formula to calculate the thermic effect of feeding:

\[ \text{TEF} = 2000 \times 0.1 = 200 \text{ cals} \]

This means that the thermic effect of feeding for this scenario is 200 cals.
