Question 1

Research on obesity and weight control indicates that

Accepted Answer

Research shows that fat tissue requires fewer calories to maintain than lean tissue, which means that an overweight or obese person may need fewer calories to maintain their weight loss compared to someone who always had a leaner body composition. A, C, and D are not supported by current research on obesity and weight control.

Question 2

Which of the following suggestions would be the WORST advice for a dieter?

Accepted Answer

Skipping meals during the day and overindulging in the evening can lead to overeating and ultimately sabotage the diet. It also puts a strain on the body's metabolic processes. It is important to maintain a healthy and balanced diet throughout the day to achieve sustainable weight loss. The other options (A, B, D) are good suggestions for dieters.

Question 3

Exercising regularly and getting enough sleep contribute to a(n)________ in metabolism and a(n)________ in the settling point.

Accepted Answer

Exercising regularly and getting enough sleep both have been proven to increase metabolism. When metabolism is increased, the body burns more calories and can potentially lead to a decrease in the settling point, which is the weight your body naturally gravitates towards. Therefore, the correct answer is a "increase in metabolism and a decrease in the settling point," which is only represented in choice C.

Question 4

A dieter whose weight falls below his or her set point is likely to experience a(n)

Accepted Answer

When a dieter's weight falls below their set point, the body responds by increasing hunger signals and decreasing the metabolic rate in an effort to regain lost weight and return to the set point. This is a physiological response known as the "starvation response."

Question 5

By dramatically reducing her daily caloric intake,Marilyn plans to reduce her normal body weight by 10 to 15 percent.Research suggests that after three or four weeks of sustained dieting,Marilyn will

Accepted Answer

Research suggests that sustained caloric restriction can lead to a reduction in resting metabolic rate due to a decrease in lean body mass and metabolic adaptations in response to the reduced energy intake. This makes it more difficult to maintain weight loss in the long term. Marilyn may also experience a decrease in feelings of hunger, but this is unlikely to occur after just three or four weeks of dieting. Blood glucose levels may vary depending on the specifics of the diet, but there is no evidence to suggest that they would consistently increase. A lower set point for body weight may be a long-term adaptation to sustained weight loss, but it is not likely to be evident after just a few weeks of dieting.

Question 6

Judy found that her party guests ate less from a very large plate of cupcakes that were cut in half rather than whole.This best illustrates

Accepted Answer

This scenario exemplifies the idea of unit bias, in which individuals are inclined to consume or consider one unit of a food item (in this case, a cupcake) as a serving size. When the cupcakes were cut in half, the guests likely perceived them as smaller servings and thus ate less overall.

Question 7

Evidence that obesity is influenced by factors in addition to genetics includes the fact that

Accepted Answer

The decline in jobs requiring moderate physical activity suggests that environmental and lifestyle factors, such as decreased physical activity, contribute to obesity beyond genetic factors.

Question 8

The body weights of adopted children ________ resemble those of their adoptive parents than those of their biological parents,and they ________ resemble those of their adoptive siblings than those of their biological siblings.

Accepted Answer

The body weights of adopted children are influenced more by their genetic makeup than by the environment provided by their adoptive parents. Therefore, their weights less closely resemble those of their adoptive parents and siblings compared to their biological parents and siblings.

Question 9

Obesity is defined as

Accepted Answer

Obesity is defined as having a body mass index (BMI) of 30 or more, which is calculated by dividing a person's weight in kilograms by their height in meters squared. A BMI of 30 or higher indicates that a person is significantly overweight and at risk for a variety of health problems. Choices A, B, and D are incorrect because they do not accurately reflect the definition of obesity.

Question 10

Isaac has been physically inactive and obese for as long as he can remember.He is now determined to lose excess weight with a reduced-calorie diet.Isaac is likely to have difficulty losing weight while dieting because

Accepted Answer

It takes fewer calories to maintain fat tissue than muscle tissue, so even with a reduced-calorie diet, Isaac's body may still be holding onto excess fat because it requires fewer calories to maintain. This can make it harder for him to lose weight compared to someone with a higher percentage of muscle mass.

Question 11

Eating food more ________ leads to eating less food.This is especially true for ________.

Accepted Answer

The answer of Eating food more ________ leads to eating...

Question 12

When encouraged to eat their fill of M&M's,people ate more when given a large rather than a small serving scoop.This most clearly reflects

Accepted Answer

Unit bias is the tendency to perceive that a single serving or unit of a particular food item is the appropriate amount to consume. In this scenario, the size of the serving scoop influenced how much people ate, indicating that they were influenced by the perceived appropriate amount or unit of M&M's to consume. Therefore, the best choice is D) Unit bias.

Question 13

When offered as many servings of ice cream as they would like to eat,people are likely to eat more if they are

Accepted Answer

The answer of When offered as many servings of ice...

Question 14

A body that can store fat has the advantage of possessing

Accepted Answer

A body that can store fat has the advantage of possessing stored energy, which can be used during periods of low calorie intake or high energy demands. Low blood pressure, a low set point, and reduced levels of serotonin are not necessarily advantages of having the ability to store fat.

Question 15

If your close friend becomes obese,the odds of you likewise becoming obese increase.This best illustrates the impact of ________ on obesity.

Accepted Answer

Social influence refers to the impact that others can have on our behavior or attitudes. In the case of obesity, research has shown that having friends or family members who are obese can increase the likelihood of an individual becoming obese themselves. This may be due to a number of factors, such as shared eating habits or decreased motivation for healthy behaviors when surrounded by others who are overweight. Therefore, the most relevant concept in this scenario is social influence.

Question 16

The sex hormone secreted in greater amounts by females than by males is

Accepted Answer

Estradiol is the primary sex hormone responsible for female reproductive development and function, and is secreted in greater amounts by females than by males. Testosterone is the primary male sex hormone, HPV is a virus that causes genital warts and cervical cancer, and serotonin is a neurotransmitter involved in regulating mood and other physiological processes.

Question 17

With sleep deprivation,the levels of leptin ________ and the levels of ghrelin ________.

Accepted Answer

Sleep deprivation causes levels of leptin to decrease, which leads to increased hunger and food intake. It also causes levels of ghrelin to increase, which further increases appetite and food intake.

Question 18

In the United States,the rate of obesity among adults has ________ over the last 40 years,and the rate of obesity among children and teens has ________.

Accepted Answer

The rate of obesity among adults and children/teens has both increased over the last 40 years, making choice C the correct answer.

Question 19

New research has linked women's obesity to their risk of late-life

Accepted Answer

The new research has linked women's obesity to their risk of late-life cognitive decline.

Question 20

The World Health Organization identifies obesity as a high

Accepted Answer

The World Health Organization (WHO) identifies obesity based on a person's Body Mass Index (BMI), which is a measure of body fat based on height and weight.
