views updated

diet‐induced thermogenesis The increase in heat production by the body after eating. It is due to both the metabolic energy cost of digestion (the secretion of digestive enzymes, active transport of nutrients from the gut, and gut motility) and the energy cost of forming tissue reserves of fat, glycogen, and protein. It can be up to 10–15% of the energy intake. Also known as the specific dynamic action (SDA), thermic effect of foods, and luxus konsumption.
