Question 1

What is a Thermic Effect of Food?

Accepted Answer

The thermic effect of food (TEF) is the energy expended digesting, absorbing, and metabolising nutrients. Protein has the highest TEF (20–30%); carbohydrates moderate (5–10%); fat lowest (0–3%). TEF accounts for roughly 10% of total daily energy expenditure.

Question 2

How does the Thermic Effect of Food work?

Accepted Answer

Protein TEF: 20–30% of protein calories burned in digestion Then: Carbohydrate TEF: 5–10% Then: Fat TEF: 0–3% Then: Total TEF = Σ(macronutrient calories × TEF rate).

Question 3

Can you give an example of how to use the Thermic Effect of Food?

Accepted Answer

Example: Input 2,000 kcal diet: 30% protein, 50% carbs, 20% fat gives a result of TEF ≈ 178 kcal/day (8.9% of intake) (High protein diets have largest thermic effect).
