UNDERSTANDING YOUR
ENERGY EXPENDITURE
In the balancing act of managing our energy intake vs energy expenditure it’s important you understand what contributes to your output.
COMPONENTS OF TOTAL DAILY
ENERGY EXPENDITURE (TDEE)
Throughout the course of a day you can bracket your expenditure into two different types.
Resting energy expenditure and BMR: This accounts for more than 60% of your total energy expenditure. Even when resting, your body utilises energy (calories) by performing basic functions to sustain life, such as breathing, circulation, the processing of nutrients and cell regeneration. This is known as your basal metabolic rate or BMR, which you can calculate by inputting your data in the boxes to the left
Non-resting energy expenditure. This is made up of three components.
NEAT or non-exercise activity thermogenesis.
NEAT is the energy expenditure we have walking, standing, climbing stairs, fidgeting and maintaining and changing posture. Anything outside of formally planned or structured exercise falls under this category.
EAT or Exercise Activity Thermogenesis
EAT is defined as planned, structured, and repetitive physical activity with the objective of improving health. Doing sport or going to the gym falls under this category. NEAT accounts for much more energy expenditure than EAT therefore habitual daily activity and movement can contribute hugely to improving energy balance.
TEF or Thermic effect of Food
As previously mentioned, this relates to the amount of energy required to digest, absorb and store food.
