The BMR accounts for 70% of the total TDEE calculation while the remaining 305 energy utilization in the body is by NREE. Lastly, the NEAT is the requirement of energy to perform everyday tasks, like simply sanding still, lying on a couch or working on your laptop.Īs for the Resting Energy Expenditure (REE), the only variable included is the Basal Metabolic Rate or BMR. While the TEF is the energy required for digestion, absorption and all the process related to food including eating. The TDEE is the energy needed by our body in order to perform daily physical movements or exercises. Non-exercise activity thermogenesis (NEAT).The non resting energy expenditure (NREE) contains the energy utilization by your body in a non-resting (physical movement) phase. Generally, the TDEE comprises two major categories, i.e the NREE and REE. Well, this guide will throw light on what the TDEE calculation is, what factors are involved in it and which formula is used to calculate TDEE. But how this TDEE is calculated, means how come TDEE knows your energy expenditure and how it calculates it? The TDEE is the metric that calculates this total energy usage by our body in a period of 24 hours.

The physical movements we do throughout the day also contribute to the energy usage by our body, in other words, even the slightest act of raising an eyebrow requires energy. This energy expenditure can be under the influence of visceral functions being carried on all the time like breathing, heart pumping, brain/neuronal activities and other organs’ activities. Whether we are having a stroll in the corridor or just lying on our couch the energy is being utilized in both conditions however the amount differs. We expend energy for every function in order to stay alive or activity our body performs. Total Daily Energy Expenditure or simply the TDEE is the number of calories we burn in a day.
