Question 1

A body weight that exceeds 100% of the normal standard for a given height is called

Accepted Answer

Morbid obesity is defined as a body weight that exceeds 100% of the normal standard for a given height, indicating a very high amount of excess weight that may pose significant health risks.

Question 2

Which of the following is NOT considered a basal function?

Accepted Answer

Walking up stairs requires additional effort and is not a basal function. Basal functions are the basic processes necessary for the body to maintain life, such as respiration, circulation, and maintaining body temperature.

Question 3

The amount of energy expended by the body in digesting, absorbing, transporting, metabolizing, and storing nutrients is called

Accepted Answer

The thermic effect of food refers to the energy expended by the body in digesting, absorbing, transporting, metabolizing, and storing nutrients from food. This energy expenditure is influenced by the composition and amount of nutrients consumed.

Question 4

A limitation in using the body mass index is that it

Accepted Answer

Body mass index only takes into account a person's weight and height, and does not consider factors such as muscle mass and bone density. This can result in athletes and people with higher muscle mass being classified as overweight or obese, even though they may not have a higher risk for health problems.

Question 5

Body mass index (BMI) is BEST described as

Accepted Answer

BMI is a measure of body fat based on an individual's weight and height. It is calculated by dividing an individual's weight in kilograms by their height in meters squared. Therefore, it is a ratio of an individual's body weight to their height squared.

Question 6

Which of the following correctly describes the energy balance equation?

Accepted Answer

The energy balance equation states that the energy consumed (in the form of food and drinks) must be equal to the energy expended (through physical activity and metabolic processes) in order to maintain weight. Therefore, the correct choice is D, which states that energy consumed equals energy expended.

Question 7

Benjamin is an 18-year-old college student who is 5'10" tall and weighs 170 pounds. How many kilocalories does he expend each day for basal metabolism?

Accepted Answer

The formula for determining basal metabolic rate (BMR) for males is: 66 + (6.23 x weight in pounds) + (12.7 x height in inches) - (6.8 x age in years).

Using this formula: 
BMR = 66 + (6.23 x 170) + (12.7 x 70) - (6.8 x 18)
BMR = 1,855.3 kcal

Therefore, Benjamin expends approximately 1,855 kcal each day for basal metabolism.

Question 8

Approximately what percentage of our total energy output is attributable to the thermic effect of food?

Accepted Answer

The thermic effect of food refers to the energy expended by the body in digesting and absorbing food. According to research, the thermic effect of food accounts for approximately 5 to 10 percent of our total energy output. Therefore, choice A (5 to 10 percent) is the best answer.

Question 9

Which of the following does NOT define a "healthy body weight?"

Accepted Answer

A healthy body weight should not be based on societal standards or expectations, but rather on individual health markers and personal satisfaction.

Question 10

The label on a ready-to-eat cereal box indicates that 1 cup contains 32 grams of carbohydrate, 4 grams of protein, and 2 grams of fat. How many kilocalories are there in two cups of this cereal?

Accepted Answer

The answer of The label on a ready-to-eat cereal box...

Question 11

Lance would like to lose two pounds a week. If his present energy intake is 4,200 kcal a day and his energy expenditure does not change, how many kilocalories should he consume each day to achieve his goal?

Accepted Answer

To lose two pounds a week, Lance needs to create a calorie deficit of 7,000 kcal per week (since 1 pound of fat is approximately 3,500 kcal). To achieve this, he should aim to have a calorie deficit of 1,000 kcal per day (since 7,000 kcal divided by 7 days equals 1,000 kcal per day).

Since his present energy intake is 4,200 kcal a day and his energy expenditure does not change, he needs to consume 1,000 fewer kilocalories each day to achieve his goal. Therefore, his new daily energy intake should be 4,200 - 1,000 = 3,200 kcal per day. Therefore, the correct answer is C.

Question 12

An apple-shaped fat pattern increases a person's risk for which kind of disease?

Accepted Answer

An apple-shaped fat pattern, where fat accumulates around the abdomen and internal organs, increases a person's risk for cardiovascular disease. This type of fat distribution is commonly seen in individuals with metabolic syndrome or insulin resistance. It is important to reduce this type of fat to lower the risk of heart disease.

Question 13

In men, a waist-to-hip ratio higher than what is associated with an increased risk for chronic disease?

Accepted Answer

A waist-to-hip ratio higher than 0.90 in men is associated with an increased risk for chronic diseases such as type 2 diabetes, heart disease, and stroke.

Question 14

Which of the following individuals would MOST likely have the lowest basal metabolic rate?

Accepted Answer

Basal metabolic rate tends to be lower in individuals with a higher percentage of body fat. Being overweight increases the likelihood that an individual has a lower basal metabolic rate.

Question 15

Robin's dinner contains 750 kilocalories. What is the minimum amount of kilocalories that Robin will expend in order to process this meal?

Accepted Answer

The answer of Robin's dinner contains 750 kilocalories. What is...

Question 16

The three components of total energy expenditure include

Accepted Answer

The three components of total energy expenditure are basal metabolic rate, physical activity, and the thermic effect of food. Basal metabolic rate is the energy needed to maintain essential bodily functions at rest, physical activity includes all movement beyond basal metabolic rate, and the thermic effect of food is the energy needed to digest, absorb, and metabolize food.

Question 17

Serena is 5'8" tall and weighs 180 pounds. Serena's BMI indicates that she is

Accepted Answer

Using the BMI formula (BMI = weight in pounds / height in inches squared x 703), Serena's BMI is calculated to be 27.4. This falls within the overweight category (a BMI between 25-29.9). Therefore, the best choice is C - overweight.

Question 18

Research studies have shown that the risk for developing type 2 diabetes and hypertension begins to increase at a BMI greater than

Accepted Answer

Research studies have shown that the risk for developing type 2 diabetes and hypertension begins to increase at a BMI greater than 30 kg/m2, which is considered obese. A BMI between 25 and 29.9 kg/m2 is considered overweight and may also increase the risk for these conditions, but the increase is not as significant as with obesity. A BMI greater than 35 kg/m2 or 40 kg/m2 is considered severe obesity and carries even higher risk for developing these conditions.

Question 19

The primary determinant of basal metabolic rate is an individual's

Accepted Answer

Lean body mass, which includes muscles and organs, requires energy to maintain. Therefore, the more lean body mass a person has, the higher their basal metabolic rate will be. Age, gender, and fat body mass can also play a role, but they are not the primary determinant.

Question 20
