Basal Energy Expenditure
What factors influence daily energy needs? Total energy expenditure includes:
- Basal metabolic rate. This reflects the energy the body needs for basic functions while at rest.
- Dietary-induced thermogenesis, or the thermic effect of food. This is the energy the body needs to digest and absorb food.
- The thermic effect of activity. This is the most variable as it reflects the energy needed for physical activity. For sedentary individuals this could be as low as 15% of total energy expenditure but for athletes it could be as high as 80%.
