18
Q

Thermic Effect of Food varies by what?

A

varies amount and composition of food

19
Q

Why does protein have a higher metabolic cost than carbohydrates and fat?

A

due to metabolism of amino acids

20
Q

TEF is estimated as

A

10% of total energy intake

21
Q

Thermoregulation can be affected by what?

A
  1. changes in environmental temperature
  2. changes in radiant energy
22
Q

What is the goal of thermoregulation?

A

to maintain constant or near-constant body temperature

23
Q

How does growth influence energy expenditure?

A

energy costs associated with tissue deposition

24
Q

What is the estimated change in calorie need during the 1st 6 months of lactation?

A

+330 calories

25
Q

What is the estimated change in calorie need during the 2nd 6 months of lactation?

A

+400 calories

26
Q

What is the estimated energy requirement (EER)?

A

the average energy intake needed to maintain balance for an adult, based on age, sex, size, weight, activity level, and life stage

27
Q

What is the EER for a 20 yr old, nonpregnant/nonlactating woman who is 165 cm in height, weighs 63 kg, and is determined to have a low active PAL?

a. 2,000 kcal/day
b. 2,150 kcal/day
c. 2,289 kcal/day
d. 2,350 kcal/day

A

c. 2,289 kcal/day

28
Q

What is the EER for a 2-year-old boy who is 98 cm in height and weighs 15.5 kg?

a. 1,105 kcal/day
b. 1,281 kcal/day
c. 1,325 kcal/day
d. 1,478 kcal/day

A

b. 1,281 kcal/day

29
Q

Why is there no RDA or UL for energy?

A

because any intake above the requirement causes weight gain, increasing risk for comorbidities

30

What are the costs of inadequate physical activity?

A

$117 billion dollars in annual health care costs

31
Q

Due to inadequate physical activity, what is the percentage of premature mortality?

32
Q

33
Q

Why is obesity a threat to national security?

A

obesity disqualifies nearly one-third of American youth, ages 17 to 24, from military service

34
Q

What are the steps in the development and implementation of the physical activity guidelines?

A
  1. appointment of PAG advisory committee
  2. review of the current science
  3. PAGAC scientific report
  4. development of physical activity guidelines
  5. implemented in federal programs and initiatives
35
Q

BMI is _______ and _______ tool

A

research and screening

36
Q

BMI should not be used for what?
