TDEE Calculator Introduction

TDEE (Total Daily Energy Expenditure) – Total energy that a person uses in a day. TDEE is hard to measure accurately and varies day by day. More often, it is estimated using factors such as a person’s basal metabolic rate (BMR), activity level, and the thermic effect of food.

Basal metabolic rate:

BMR is a person’s energy usage rate while at rest in a moderate environment when the digestive system is inactive. In other words, it is the minimum energy needed to maintain a person’s vital organs only.

Activity level:

Activity level is a factor that is based on the amount of activity a person undergoes. This includes deliberate exercise as well as other activities that a person may undergo as part of their job or typical daily activities. These factors are more specifically referred to as the thermic effect of activity, and non-exercise activity thermogenesis (energy expended for non-sleeping, eating, or sports-like exercise).

Thermic effect of food:

The thermic effect of food, also referred to as specific dynamic action, is the amount of energy required by the body to process and use food. It is sometimes estimated as 10% of food energy intake, but this can vary significantly dependent on the type of food consumed. Protein for example, has a far larger thermic effect than dietary fat, since it is more difficult to process.
