What Is The Thermic Effect Of Feeding?

Thermic effect of feeding (TEF) accounts for the energy used to digest, absorb and assimilate the food we eat and makes up approximately 10% of daily expenditure.

This is one of the reasons higher protein intakes are recommended on a weight loss / fat loss protocol. Protein has the highest digestive energy cost of all the macronutrients. 

In addition whole foods will typically have a higher TEF value compared to their processed food counterparts. In practical terms this means for every 100 calories of food eaten you eat absorb a smaller percentage of those calories when they come from whole foods. Yet enough reason to make nutritious whole foods the centerpiece of your diet strategy
