Your non-resting energy expenditure (NREE) is a mix of three components which include non-exercise thermogenesis (NEAT), thermic effect of food (TEF), and exercise activity thermogenesis (EAT). Here we take a closer look at what TDEE is, what factors affect it, and how it is calculated as well as offer some tips on how to boost your TDEE by simply rethinking your day and adding more movement. undertake physical exercise.

The three macronutrientscarbs, proteins, and fatsrequire a different amount of energy to breakdown and assimilate into your digestive system.
