Q: A 25-year-old woman (weight: 60 kg, height: 1.65 m, PA = 1.27) wants to estimate her EER. Which formula should she use?

$$EER = 354 - 6.91 \times \text{age} + PA \times [(9.36 \times \text{wt}_{kg}) + (726 \times \text{ht}_m)]$$

Q: A 40-year-old male, 90 kg, 1.80 m tall, is very active (PA = 1.48). What is the first step in calculating his EER?

Substitute the values into $$EER = 662 - 9.53 \times \text{age} + PA \times [(15.91 \times \text{wt}_{kg}) + (539.6 \times \text{ht}_m)]$$

Q: Which of the following is a correct conversion for body weight from pounds to kilograms?

$$\text{kg} = \frac{\text{lb}}{2.2}$$

Q: Which of the following is the correct formula for converting height from inches to meters?

$$\text{m} = \frac{\text{inches}}{39.37}$$

Question 1

Which of the following best describes the concept of energy balance in the human body?

Accepted Answer

Energy intake equals energy expenditure, resulting in weight maintenance.

Question 2

A food’s calorie value is determined using a bomb calorimeter. What does one kilocalorie (kcal) represent?

Accepted Answer

The amount of energy needed to raise the temperature of 1 kg of water by 1°C.

Question 3

If a person consumes 3000 kcal per day but only needs 2000 kcal per day, what is the expected weekly weight change? (Assume 1 lb = 3500 kcal)

Accepted Answer

$$+2$$ lbs per week

Question 4

Which of the following is NOT a component of total energy expenditure (TEE)?

Accepted Answer

Glycogen storage

Question 5

A 25-year-old woman (weight: 60 kg, height: 1.65 m, PA = 1.27) wants to estimate her EER. Which formula should she use?

Accepted Answer

$$EER = 354 - 6.91 	imes 	ext{age} + PA 	imes [(9.36 	imes 	ext{wt}_{kg}) + (726 	imes 	ext{ht}_m)]$$

Question 6

Which factor would most likely increase a person’s basal metabolic rate (BMR)?

Accepted Answer

Higher lean body mass

Question 7

If a person has an energy deficit of 400 kcal per day for one week, how much weight loss should be expected? (1 lb = 3500 kcal)

Accepted Answer

$$-0.8$$ lbs

Question 8

Which of the following best describes the thermic effect of food (TEF)?

Accepted Answer

The energy expended in the metabolism of food after a meal

Question 9

A 40-year-old male, 90 kg, 1.80 m tall, is very active (PA = 1.48). What is the first step in calculating his EER?

Accepted Answer

Substitute the values into $$EER = 662 - 9.53 	imes 	ext{age} + PA 	imes [(15.91 	imes 	ext{wt}_{kg}) + (539.6 	imes 	ext{ht}_m)]$$

Question 10

Which of the following scenarios would most likely result in weight maintenance?

Accepted Answer

Energy intake equals energy need

Question 11

Which of the following is a correct conversion for body weight from pounds to kilograms?

Accepted Answer

$$	ext{kg} = \frac{	ext{lb}}{2.2}$$

Question 12

Which of the following is a plausible reason why a person’s BMR might decrease?

Accepted Answer

Older age

Question 13

If a person’s energy intake is consistently less than their energy need, what is the likely outcome?

Accepted Answer

Weight loss

Question 14

Which of the following is the correct formula for converting height from inches to meters?

Accepted Answer

$$	ext{m} = \frac{	ext{inches}}{39.37}$$

Question 15

Which of the following statements about the accuracy of the EER calculation is correct?

Accepted Answer

The EER is an estimate and may vary by about ±10%.

Question 16

Which of the following would NOT increase basal metabolic rate (BMR)?

Accepted Answer

Female gender due to decreased lean tissue

Question 17

A person eats an extra 500 kcal per day for 2 weeks. How much weight gain would you expect? (1 lb = 3500 kcal)

Accepted Answer

$$2$$ lbs

Question 18

Which of the following is the largest contributor to total energy expenditure in most people?

Accepted Answer

Basal metabolic rate (BMR)

Question 19

Which of the following is a correct interpretation of the physical activity coefficient (PA) in the EER equation?

Accepted Answer

It adjusts the EER based on the individual’s activity level.

Question 20

Which of the following scenarios best illustrates the thermic effect of food (TEF)?

Accepted Answer

A person’s metabolism increases for several hours after eating a large meal.
