Understanding Thermic Effect of Food
The Thermic Effect of Food (TEF) is the amount of energy your body uses to digest, absorb, and metabolize the food you eat. Different macronutrients have different thermic effects:
- Protein: 20-30% of calories burned
- Carbohydrates: 5-10% of calories burned
- Fat: 0-3% of calories burned
The TEF is calculated based on your total calorie intake and the distribution of macronutrients in your diet. A higher protein intake generally leads to a higher TEF.
