Which component of daily energy expenditure supports essential functions such as breathing and circulation, and is generally the largest component?
- A
Thermic effect of food
- B
Resting energy expenditure
- C
Physical activity expenditure
- D
Adaptive thermogenesis
A person’s body uses energy to digest, absorb, and process a meal. Which expenditure component does this describe?
- A
Energy used for planned exercise
- B
Energy used to digest, absorb, and process food
- C
Energy used for breathing and circulation
- D
Energy used only during sleep
The NIDDK Body Weight Planner’s estimates are intended for adults, but not for people who are pregnant or .
Select all factors the material identifies as influencing energy needs or contributing to differences in body weight regulation.
- A
Growth and pregnancy
- B
Hydration alone
- C
Age and life stage
- D
Genetics and hormones
What acronym names energy expenditure from everyday movement outside planned exercise, such as walking around the home, standing, and doing chores?
True or false: The same calorie intake should maintain every person’s body weight, even when their body weight or activity changes.
- A
True
- B
False
Adaptive thermogenesis refers to changes in energy use in response to altered food intake, body weight, or .
Using change in body energy stores=energy intake−energy expenditure, calculate the change when intake is 2,400 kcal and expenditure is 2,650 kcal. Enter the result in kcal.
Select all responses that may occur as weight is lost, according to the material.
- A
Leptin levels commonly fall
- B
Appetite may increase
- C
Leptin levels commonly rise
- D
Energy expenditure may decline
After a person loses weight, which signal commonly falls and is associated with stored energy, potentially accompanying increased appetite and lower energy expenditure?
- A
Insulin, which the material identifies as the signal that always prevents hunger
- B
Glycogen, which is described as a hormone made by fat cells
- C
Leptin, a fat-cell hormone related to stored energy
- D
Thermic effect, a hormone that signals fullness
Someone sees a short-term change on the scale, but the change does not necessarily represent a change in body fat. Which group of factors could help explain the scale change?
- A
Only newly gained body fat
- B
Water, glycogen, and food in the digestive tract
- C
Only muscle tissue
- D
A change in resting energy expenditure by itself
Explain why continued weight loss and maintaining a lower weight can become more difficult after a person has lost weight. Describe at least two linked changes in energy needs, hunger, or energy use.
A person’s intake previously matched their expenditure and their weight was relatively stable. After they lose weight, they keep the same intake and activity. Which explanation best describes why their energy balance might shift?
- A
The smaller body may use less energy at rest and for movement, so unchanged intake could become a surplus
- B
Weight loss makes the body require more energy for every movement, so unchanged intake must become a deficit
- C
Energy expenditure cannot change as body weight changes
- D
A previous calorie estimate is a fixed prescription that applies regardless of activity
A person does not do planned exercise but spends the day standing, walking around the home, and doing chores. Which component of energy expenditure best describes this everyday movement?
- A
Resting energy expenditure
- B
Non-exercise activity thermogenesis (NEAT)
- C
Thermic effect of food
- D
Adaptive thermogenesis
Which description best characterizes resting energy expenditure (REE)?
- A
Energy used only during planned exercise
- B
Energy used to digest and process food
- C
Energy used for essential functions such as breathing and circulation
- D
Energy stored after a meal
What component of daily energy expenditure is the energy used to digest, absorb, and process food?
What term describes changes in energy use in response to conditions such as altered food intake, body weight, or temperature?
When a person loses weight, leptin levels commonly fall, and appetite may increase while energy expenditure may decline.
- A
True
- B
False
Which situation is specifically identified as increasing energy needs because of life stage?
- A
Growth and pregnancy
- B
Standing and doing household chores
- C
Digesting and absorbing food
- D
Maintaining tissues at rest
