What does the body’s total daily energy expenditure include?
Total daily energy expenditure (TEE) can be divided into four major components, including resting metabolic rate (RMR), the thermic effect of food, physical energy expenditure, and non-exercise activity thermogenesis (see Chapter 27 for details).
What are the components of total energy expenditure?
2 Total energy expenditure (TEE) is the energy required by the organism daily and it is determined by the sum of 3 components: basal energy expenditure (BEE), diet- induced thermogenesis (DIT) and physical activity (PA).
What are the 3 components of energy expenditure quizlet?
Explain the THREE components of energy expenditure.
- Basal Metabolic Rate- Energy needed to maintain core body functions.
- Physical Activity – Energy needed to move muscles.
- Thermic effect on food – energy needed to process food.
What are the three major components of total energy expenditure in the body?
The three components of energy expenditure: resting energy expenditure (closed bar), diet-induced energy expenditure (stippled bar), and activity-induced energy expenditure (open bar) as observed in subjects who are lean and who have obesity.
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 is total energy expenditure Issa?
Total Energy expenditure is the amount of calories burned by the human body in one day adjusted to the amount of activity (sedentary, moderate or strenous). It is calculated by adding 30% of the Basal Energy Expenditure (BEE) calories to the BEE for sedentary activity.
What is resting daily energy expenditure?
Resting energy expenditure (REE) represents energy expenditure while a person lies quietly awake in an interprandial state; under these conditions, approximately 1 kcal/kg body weight is consumed/hour in healthy adults. Energy requirements of specific tissues differ dramatically (Table 4-2).
What accounts for most of your daily energy expenditure quizlet?
Terms in this set (24)
- resting metabolic rate (60-75%)
- thermic effect of feeding (10%)
- thermic effect of physical activity (15-30%)
What is the daily energy requirement of human body?
The average allowance for men of reference size (77 kg) is 2,300 kcal/day; for women, it is 1,900 kcal/day. A normal variation of ±20% is accepted as for younger adults. The requirements of persons beyond age 75 are likely to be somewhat less as a result of reduced body size, REE, and activity.
What is the largest component of energy expenditure?
basal metabolic rate (BMR) In the great majority of cases the largest component of energy expenditure is the basal metabolic rate (BMR), which can be measured with accuracy under standardized conditions.
What is resting energy expenditures quizlet?
Resting energy expenditure is the amount of energy the body needs to maintain normal physiological functions to survive. It is also known as the metabolic rate of the body while at rest.
What accounts for most of your daily energy expenditure?
BMR The body's BMR accounts for the largest amount of energy expended daily (50–80 per cent of your daily energy use). Thermic effect of food (also known as thermogenesis) – your body uses energy to digest the foods and drinks you consume and also absorbs, transports and stores their nutrients.
Which factors determine total energy expenditure quizlet?
What are the 3 components that affect total daily energy expenditure (TDEE)? You just studied 24 terms!…
- Physical activity.
- Diet-induced thermogenesis.
- Calorigenic effect of food on exercise metabolism.
- Climate.
- Pregnancy.
What is the average daily energy expenditure?
Average daily Total Energy Expenditure estimated to be 2900 – 3000 kCal for males, and 2200 kCal for females 15-50 y.o.a.
Which factors determine total energy expenditure tee )?
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.
