What percentage does food consumption account toward energy expenditure?
How does age affect energy expenditure?
Energy expenditure increases with weight gain at adult age through a consequent increase in maintenance metabolism. Smaller and leaner subjects generally move more as activity energy expenditure in larger subjects is not higher in proportion to the cost of moving with a higher body weight.
What increases energy expenditure?
Total energy expenditure (TEE) consists of four components, i.e., the sleeping metabolic rate (SMR), the energy cost of arousal, the thermic effect of food or diet-induced energy expenditure (DEE), and the energy cost of physical activity or AEE.
Energy expenditure is the sum of the basal metabolic rate (the amount of energy expended while at complete rest), the thermic effect of food (TEF, the energy required to digest and absorb food) and the energy expended in physical activity.
How is food intake affects the energy expenditure?
approximately 10 percent
It takes energy to process the food you eat. Digestion of the food and the absorption, metabolism and storage of the nutrients account for approximately 10 percent of your total energy expenditure. The composition of your meal determines its TEF.
