What does energy expenditure depend on?
The main determinants of energy expenditure are body size and body composition, food intake and physical activity. Food intake and physical activity affect energy expenditure directly and indirectly, the latter through the effect of food intake and physical activity on body size and body composition.
What 2 major factors make up total daily energy expenditure?
Daily energy expenditure is composed of three major components: 1) resting metabolic rate (RMR); 2) the thermic effect of feeding (TEF); and 3) the thermic effect of activity (TEA). RMR constitutes 60 to 75% of daily energy expenditure and is the energy associated with the maintenance of major body functions.
What are the two types of energy expenditure?
Basal energy expenditure and resting energy expenditure The REE is the amount of energy expended by a resting individual in a thermoneutral environment without the effects of meal consumption, physical activity, or physiological or mental stress [9,13,43,44].
What 3 factors make up energy expenditure?
Your metabolic rate or the amount of energy you expend daily is determined by three factors. These are your resting metabolic rate, the thermic effect of activity, and the thermic effect of the food you eat.
What is energy expenditure?
Energy expenditure refers to the amount of energy an individual uses to maintain essential body functions (respiration, circulation, digestion) and as a result of physical activity.
What other factors can affect daily energy expenditure?
Factors Influencing Energy Expenditure. Resting energy expenditure is influenced by age, sex, body weight, pregnancy, and hormonal status. The highest rates of energy expenditure per unit of body weight occur during infancy and decline through childhood.
What is energy expenditure quizlet?
Total Energy Expenditure. The total of all calories expended during the course of one 24-hour day. Basal Energy Expenditure. A large part of (typically about 60%) daily expenditure is due to the basal metabolism or ___________ Basal Metabolic Rate.
What makes up total energy expenditure?
BMR = basal metabolic rate; NEAT = non-exercise activity thermogenesis; TEF = thermic effect of food; EAT = exercise activity thermogenesis; REE = resting energy expenditure; NREE = non-resting energy expenditure.

What factors affect energy needs?
Factors influencing energy requirements
- Gender. Adult males often have about 10-20% more muscle mass than females of the same size and age.
- Physical Activity Levels (PAL)
- Specific needs.
