In this segment, the presenter explains the thermic effect of food (TEF), describing how the body expends calories to digest what we eat. Different macronutrients have distinct TEF values: dietary fat burns only 1–3 calories per 100 calories consumed, carbohydrates burn 3–7 calories per 100, and protein can burn up to 30 calories per 100. The speaker highlights that higher protein intake can increase calorie expenditure, which may help some individuals lose weight or improve body composition despite eating more food.
