Your body doesn’t just burn calories during exercise, it does it during digestion too. Learn more about the thermic effect. What the heck is the thermic effect of food, how big of an impact does it have, and can I harness it to work for me as I try to build lean mass?
The thermic effect of food is the caloric cost of digesting and processing different macronutrients in your diet. There is evidence that scientists have known about this phenomenon since the early 1900s. Amazingly, despite what we could consider greatly antiquated methods, researchers over 75 years ago were able to accurately determine the different thermic effects of each of the different macronutrients.
