The thermogenic effect of food is highest for:
Ans- B. Carbohydrates
The thermogenic effect is extra calories procured after diet. It is highest for Carbohydrates.
The increase in energy expenditure consecutive to eating (i.e. thermic effect of food) reflects
(i) an obligatory thermogenesis component which is the energy cost of handling of exogenous macronutrients all requiring extra ATP’s, essentially: active intestinal macronutrients absorption, substrate storage, and conversion in the tissues and organ, increased macronutrient turnover in the postprandial phase.
(ii) a facultative thermogenesis component which is mediated by the sympathetic nervous system, particularly for high carbohydrate foods.
