Question

The ingestion of which nutrient type results in the greatest food-induced thermogenesis?

Answer 1

Proteins

Proteins is the most thermogenic of all nutrients and macromolecules we eat. Thermogenesis is the generation of due to digestion and metabolism of food.  Studies shows that  proteins tend to be more thermogenic that carbohydrates and fats. This means that the calorie given of by proteins is converted and released as heat and less available for storage. This means that the stored energy formed from protein much of it is released as heat and unlike other macromolecules few of it is converted to a energy that can be stored.
