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. 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). This includes deliberate exercise as well as other activities that a person may undergo as part of their job or typical daily activities.
In other words, it is the minimum energy needed to maintain a person's vital organs only.Īctivity level is a factor that is based on the amount of activity a person undergoes. More often, it is estimated using factors such as a person's basal metabolic rate (BMR), activity level, and the thermic effect of food.īMR is a person's energy usage rate while at rest in a temperate environment when the digestive system is inactive. TDEE is hard to measure accurately and varies day by day. It is the total energy that a person uses in a day. TDEE stands for total daily energy expenditure.
