Question 1

Prescription drugs are usually recommended only to people with a BMI over
A) 40.
B) 15.
C) 20.
D) 30.

Accepted Answer

Prescription drugs for weight loss are typically recommended to people with a BMI of 30 or higher. This is because they are designed to treat obesity, which is defined as having a BMI of 30 or higher. Therefore, the best choice is D, as it is the only answer that corresponds to a BMI of 30 or higher.

Question 2

A hormone thought to be linked to obesity is
A) epinephrine.
B) leptin.
C) adrenalin.
D) creatine.

Accepted Answer

Leptin is a hormone that is primarily secreted by adipose (fat) cells and helps to regulate energy balance in the body. It is often referred to as the "satiety hormone" because it helps to signal to the brain when the body has enough energy stores and can stop eating. However, research has shown that obese individuals often have high levels of leptin but are resistant to its effects, leading to continued overeating and weight gain. Therefore, leptin has been implicated in obesity and related metabolic disorders.

Question 3

Diets high in protein and saturated fat have been linked with all of the following, EXCEPT:
A) low breathing rate.
B) cancer.
C) high blood pressure.
D) increased risk of heart disease.

Accepted Answer

Diets high in protein and saturated fat have been linked with high blood pressure, increased risk of heart disease, and cancer. However, there is no direct relationship between such diets and low breathing rate.

Question 4

All of the following are factors in the development of diabetes, EXCEPT
A) a diet high in protein.
B) physical inactivity.
C) age.
D) obesity.

Accepted Answer

A diet high in protein is not a direct factor in the development of diabetes. However, a diet high in saturated and trans fats, added sugars, and refined carbohydrates can contribute to the development of type 2 diabetes. Factors such as physical inactivity, age, and obesity are known to increase the risk for developing diabetes.

Question 5

To lose one kilogram, you need to create a negative energy balance of calories.
A) 500
B) 3,500
C) 7,000
D) 1,000

Accepted Answer

To lose one kilogram of body weight, you need to create a calorie deficit of approximately 7,000 calories.

Question 6

Which of the following is the correct formula to calculate BMI?
A) Height Squared (metres) divided by Body Weight (kilograms)
B) Height (metres) divided by Body Weight (kilograms)
C) Body Weight (kilograms) divided by Height Squared (metres)
D) Body Weight (pounds) divided by Height Squared (inches)

Accepted Answer

The correct formula for calculating BMI is dividing body weight (in kilograms) by height squared (in meters).

Question 7

Question 8

Alan is somewhat surprised that he has gained a couple of kilograms since coming to university. He has never had a weight problem. He was always active every day in high school sports. Alan admits that his eating habits probably aren't as good as they should be. Still, he eats only three meals a day and a snack at night. He doesn't snack between meals because he doesn't get hungry. The food servers in the cafeteria where he eats always give him generous servings of food. Alan isn't involved with any university sport, but he does play basketball with his friends occasionally. He also has a part-time job and has a full course load. Alan thinks he is more active in university than when he was in high school. In fact, he often feels rushed going to classes because of the distance betwee classroom buildings and the fact that most of his classes are on the third or fourth floor an he has to wait to get an elevator. What additional consideration would help Alan manage his weight? He should
A) quit his part-time job.
B) reduce calories from complex carbohydrates.
C) reduce portion sizes.
D) increase calories from protein.

Accepted Answer

The most helpful consideration for Alan to manage his weight would be to reduce his portion sizes. The fact that he is eating three meals a day and a snack at night is not necessarily the issue, but the generous servings he is receiving in the cafeteria could be contributing to his weight gain. By reducing his portion sizes, he can still get the necessary nutrients he needs without overeating. Quitting his part-time job or increasing calories from protein may not necessarily have a significant impact on his weight management, and reducing calories from complex carbohydrates could potentially affect his energy levels and overall health.

Question 9

All of the following weight-management strategies are typical of participants in the National Weight Control Registry, EXCEPT
A) 60 or more minutes of daily moderate physical activity.
B) diets moderate in calories and relatively low in fat.
C) frequent monitoring of food intake and body weight.
D) very-low-carbohydrate diets.

Accepted Answer

The National Weight Control Registry does not promote or endorse very-low-carbohydrate diets as a weight-management strategy.

Question 10

Which of the following is NOT one of the three interrelated disorders comprising the female athlete triad?
A) physical inactivity
B) amenorrhea
C) osteoporosis
D) abnormal eating patterns

Accepted Answer

The three interrelated disorders comprising the female athlete triad are amenorrhea (absence of menstruation), osteoporosis (reduced bone density), and abnormal eating patterns (including restrictive eating and/or purging behaviors). Physical inactivity is not one of the disorders.

Question 11

Uva-ursi is claimed to:
A) serve as a laxative.
B) suppress appetite.
C) serve as a diuretic.
D) stimulate the CNS.

Accepted Answer

Uva-ursi is a diuretic which increases urine flow and can be used to treat urinary tract infections. It does not function as a laxative, suppress appetite, or stimulate the central nervous system.

Question 12

What is the over-the-counter, lower dose version of the prescription fat-blocking drug Orlistat?
A) sibutramine
B) leptin
C) Alli
D) phentermine

Accepted Answer

Alli is the over-the-counter, lower dose version of Orlistat. Sibutramine and phentermine are appetite suppressants, while leptin is an injectable hormone used for weight loss only in certain medical conditions.

Question 13

Which of the following statements about genetic factors in obesity is TRUE?
A) Genetic factors influence body fat distribution.
B) The weight of an adopted child is more closely related to the weights of the adoptive parents than to the weights of the biological parents.
C) Researchers have identified a single gene responsible for obesity.
D) The genetic contribution to obesity is about 75%.

Accepted Answer

Genetic factors do play a role in determining body fat distribution, with certain genes influencing whether fat is stored in the abdomen or in other areas of the body. However, the other options are not accurate. Option B is false - studies have consistently found that adoptive children's weights are more closely related to those of their biological parents than to their adoptive parents. Option C is also false - obesity is a complex trait that results from the interplay of multiple genes, each with a small effect. No single "obesity gene" has been identified. Option D is an overestimate - most estimates of the genetic contribution to obesity range from 40-70%.

Question 14

Obesity is associated with all of the following health risks, EXCEPT?
A) gallbladder and kidney diseases.
B) hypotension.
C) impaired immune function.
D) impotence.

Accepted Answer

Obesity is actually associated with hypertension (high blood pressure), not hypotension (low blood pressure). Obesity can lead to many other health risks, including type 2 diabetes, cardiovascular disease, stroke, certain cancers, and sleep apnea.

Question 15

Unpleasant effects of a low carbohydrate diet include all of the following, EXCEPT:
A) bad breath.
B) appetite suppressant.
C) constipation.
D) headache.

Accepted Answer

Appetite suppressant is not an unpleasant effect of a low carbohydrate diet, but rather a potential benefit. The other options (bad breath, constipation, headache) are all common unpleasant side effects of a low carbohydrate diet.

Question 16

Exercise affects metabolic rate by doing all of the following, EXCEPT
A) building strength during exercise.
B) burning calories during the exercise itself.
C) increasing resting metabolic rate.
D) increasing muscle mass.

Accepted Answer

Building strength during exercise can indirectly affect metabolic rate by increasing muscle mass and therefore increasing resting metabolic rate. However, directly building strength during exercise does not affect metabolic rate. The other choices - burning calories during exercise, increasing resting metabolic rate, and increasing muscle mass - are all ways in which exercise can affect metabolic rate.

Question 17

What protects against weight gain and is essential for maintaining weight loss?
A) a 1, 000-calories-per-day diet plan
B) certain nutritional supplements
C) physical activity
D) at least 8 glasses of water per day

Accepted Answer

Physical activity is essential for maintaining weight loss and helps protect against weight gain by burning calories and building muscle mass. A 1,000-calorie-per-day diet plan is too restrictive and may lead to nutrient deficiencies and health problems. Certain nutritional supplements may have some benefits, but they are not a substitute for healthy eating and physical activity. Drinking at least 8 glasses of water per day is important for overall health, but it alone does not protect against weight gain or maintain weight loss.

Question 18

Which of the following foods has a low energy-density value?
A) apple
B) popcorn
C) white bread
D) pretzels

Accepted Answer

Apples have a low energy density since they are high in water and fiber, which provide volume without adding calories. Popcorn, white bread, and pretzels all have a higher energy density since they are more calorie-dense and contain less water and fiber.

Question 19

Which of the following is an appropriate use of food?
A) as a pickup for fatigue
B) to alleviate loneliness
C) as an antidote for boredom
D) to satisfy hunger needs

Accepted Answer

The appropriate use of food is to satisfy hunger needs, as it provides essential nutrients and energy for the body to function properly. Using food for emotional reasons, such as to alleviate loneliness or boredom, can lead to unhealthy eating habits and potential health problems. Using food as a pickup for fatigue may also lead to dependence on caffeine or sugar, rather than addressing the root cause of the fatigue.

Question 20

Bitter orange extract is claimed to:
A) serve as a laxative.
B) suppress appetite.
C) serve as a diuretic.
D) stimulate the CNS.

Accepted Answer

The answer of Bitter orange extract is claimed to:
A) serve...
