Question 1

Rhonda has gained fifteen pounds since she started a sedentary part-time job and began eating fast food more frequently.Her weight gain is likely due to ________ factors.

Accepted Answer

Rhonda's weight gain is likely due to environmental factors such as her sedentary job and frequent consumption of fast food. Genetic and gender factors may play a role in weight but in this case, the environmental factors are more likely the cause of Rhonda's weight gain. Psychological factors may also contribute, but are not mentioned in the scenario.

Question 2

Which of the following factors should be considered when evaluating whether or not a person is a healthful weight?

Accepted Answer

All of the factors listed should be considered when evaluating whether or not a person is a healthful weight. Body composition takes into account the amount of muscle, bone, and fat in a person's body, which is important for overall health. Age can affect body composition and therefore impact what is considered a healthy weight for an individual. Body type can also play a role in determining a person's healthy weight. Therefore, all of these factors should be considered to determine if a person is at a healthful weight.

Question 3

Obesity is associated with lower levels of this type of cholesterol.

Accepted Answer

Obesity is associated with lower levels of HDL or "good" cholesterol. This is because HDL helps to remove excess cholesterol from the body, and obesity can interfere with its production and function. As a result, individuals who are overweight or obese may be more likely to have higher levels of LDL or "bad" cholesterol, which can increase the risk of heart disease and other health problems.

Question 4

Shonda is an obese female who is trying to plan her pregnancy.By losing weight before conceiving she will reduce her risk of all the following complications during pregnancy except

Accepted Answer

Losing weight before conceiving can reduce the risk of developing insulin resistance, high blood glucose, and high blood pressure during pregnancy. However, it is unlikely to decrease the risk of low blood sugar during pregnancy, as this is typically associated with gestational diabetes or other medical conditions unrelated to weight.

Question 5

Jermaine has a waist measurement of 41 inches,high blood pressure,and elevated triglycerides.This is characteristic of which condition?

Accepted Answer

The combination of a waist measurement over 40 inches in men, high blood pressure, and elevated triglycerides is characteristic of metabolic syndrome. This condition increases the risk of developing type 2 diabetes and coronary heart disease.

Question 6

Obese people are at a higher risk of developing sleep ________,a condition in which a person may stop breathing for short periods during sleep.

Accepted Answer

Obese people have excess fat in the neck and throat area, which can cause the airway to become blocked during sleep, leading to sleep apnea.

Question 7

Which of the following factors can increase a person's risk for obesity?

Accepted Answer

All of the factors listed can increase a person's risk for obesity. Having obese parents can indicate a genetic predisposition to obesity. A long car commute can lead to less physical activity and more sedentary behavior. Having a specific variety of an FTO gene has been linked to a higher likelihood of obesity.

Question 8

According to the Centers for Disease Control and Prevention,obesity

Accepted Answer

All of the options in the question are correct. Obesity affects over 60% of U.S. adults, is considered a national epidemic, and is spreading globally.

Question 9

All of the following factors contribute to a lower basal metabolic rate except

Accepted Answer

Being tall actually contributes to a higher basal metabolic rate because taller people have a larger surface area and therefore require more energy for basic bodily functions. The other factors listed - being over 40, physically inactive, and short - are all known to contribute to a lower basal metabolic rate.

Question 10

Waist-to-hip ratio assesses a person's

Accepted Answer

Waist-to-hip ratio assesses the distribution of fat on a person's body, specifically focusing on where they carry fat. This can indicate their risk for certain diseases such as cardiovascular disease and diabetes. It is not a measure of percentage of body fat or body mass index, so options A and C are not correct. Therefore, only option B is the best choice.

Question 11

Bob is 6'1" and 204 pounds,with a BMI of 27.According to a standard BMI chart,Bob is

Accepted Answer

According to a standard BMI chart, a BMI of 27 falls in the "overweight" category. Therefore, choice C is the best answer.

Question 12

When the calories you consume equal the calories you expend,you have achieved

Accepted Answer

Energy balance is achieved when the calories consumed and the calories expended are equal, meaning that there is no net gain or loss of weight. This is important for maintaining a healthy body weight and overall health. A and B are incorrect because achieving a calorie balance does not necessarily result in weight loss or weight gain. D (thermogenesis) refers to the process of heat production in the body, which is not related to calorie balance.

Question 13

The majority of the energy a person utilizes daily goes toward

Accepted Answer

Basal metabolism (also known as basal metabolic rate, or BMR) is the amount of energy required to maintain essential body functions at rest, such as breathing and circulation. This accounts for the majority of daily energy expenditure in most people, typically ranging from 50-70%. Digesting food (A) requires energy, but only accounts for about 5-10% of daily energy expenditure. Regulating body temperature (B) also requires energy, but typically only accounts for about 10-15% of daily energy expenditure. Physical activity expenditure (C) varies widely depending on the individual's level of physical activity, but generally accounts for only a small fraction of daily energy expenditure compared to basal metabolism.

Question 14

Type 2 diabetes most often affects individuals who are overweight or obese due to

Accepted Answer

Type 2 diabetes is characterized by insulin resistance, meaning that the body's cells do not respond effectively to insulin, leading to high levels of glucose in the blood. Being overweight or obese is a significant risk factor for developing insulin resistance and type 2 diabetes. While reduced levels of blood glucose would not cause diabetes, low blood pressure or the inability of the pancreas to manufacture insulin could contribute to diabetes but are not typically the primary cause of type 2 diabetes.

Question 15

An estimated ________ of American children and teenagers between the ages of 12 to 19 are overweight.

Accepted Answer

According to the Centers for Disease Control and Prevention (CDC), approximately 17% of American children and adolescents between the ages of 12 and 19 are overweight. This percentage has tripled since the 1970s, and obesity has become a significant public health concern in the United States.

Question 16

A person who is overweight is more likely to have high blood pressure than an average weight person for all the following reasons except

Accepted Answer

An increased capacity of the blood vessels to transport blood is not a reason for an overweight person to have high blood pressure. In fact, the opposite may be true, as excess body weight can lead to reduced elasticity of blood vessels and increased resistance to blood flow, causing high blood pressure. B, C, and D are all factors that can contribute to high blood pressure in overweight individuals.

Question 17

Obesity is associated with an increased risk of developing which of the following cancers?

Accepted Answer

Obesity is associated with an increased risk of developing all of the mentioned cancers.

Question 18

All of the following factors have contributed to the obesity epidemic in the U.S.except

Accepted Answer

A low intake of dietary protein has not been identified as a contributing factor to the obesity epidemic in the U.S. In fact, some studies suggest that higher protein diets may actually aid in weight loss and weight management. Factors B, C, and D have all been identified as contributing factors to the obesity epidemic.

Question 19

Most first year college students gain ________ pounds.

Accepted Answer

Studies have shown that most first-year college students gain an average of 7-8 pounds, which is often referred to as the "freshman 15" but is actually a lower amount on average. Choice B, C, and D are not accurate averages for the amount of weight gain seen in most first-year college students.

Question 20

All of the following factors contribute to first-year college student weight gain except

Accepted Answer

The answer of All of the following factors contribute to...
