Question 1

Why will an overweight person be unsuccessful with long-term dieting without exercise?

Accepted Answer

The body's set point is the weight range in which the body naturally wants to maintain. When an overweight person undergoes a long-term diet without exercise, the body's set point will still be maintained, making it difficult to sustain weight loss. Exercise helps increase the metabolic rate, which can assist in reducing overall body fat and help the body maintain a lower set point.

Question 2

Regarding social-cultural factors involved in body weight,which of the following is true?

Accepted Answer

The statement regarding government subsidies and obesity rates in Czech Republic suggests that social-cultural factors, such as government policies and food norms, can have an impact on body weight. Options A, B, and D are incorrect as they do not accurately reflect the role of social-cultural factors in body weight.

Question 3

____ refers to a certain level of body fat that the body strives to maintain constant throughout our lives.

Accepted Answer

The term "set point" refers to the idea that our bodies have a certain level of body fat that they try to maintain as a form of homeostasis. This means that even with changes in diet and exercise, our bodies will work to maintain this set point, making it difficult to lose weight in some cases.

Question 4

When do fat cells multiply?

Accepted Answer

Fat cells multiply when an individual is obese as the body stores excess energy in the form of fat. As fat cells fill up with stored fat, they can become enlarged and divide to form new fat cells, causing an increase in the overall number of fat cells in the body.

Question 5

Why do smokers gain weight when they quit smoking?

Accepted Answer

Nicotine raises the metabolic rate, which means when smokers quit, they burn fewer calories than they did while smoking, often leading to weight gain if they don't adjust their diet or increase their physical activity.

Question 6

The higher one's metabolic rate,the:

Accepted Answer

A higher metabolic rate means that the body burns more energy (in the form of calories). This makes it less likely that excess fuel (calories) will be stored as fat. Therefore, choice C is the correct option.

Question 7

Wayne eats a seven-course dinner and claims he cannot eat another bite of food.Then the waiter brings the dessert tray to the table,and Wayne finds that he's hungry for the pecan pie with whipped cream.His hunger is most likely due to:

Accepted Answer

Wayne's sudden hunger for dessert despite feeling full can be attributed to psychosocial hunger factors, such as the appeal and temptation of seeing a desirable food item, which can override feelings of satiety.

Question 8

What effect have cultural pressures regarding hunger had on women in China?

Accepted Answer

Cultural pressures regarding hunger in China have led to an increased concern among women regarding their weight. Women are more likely to feel pressured to maintain a slim figure, leading to a preoccupation with dieting and weight management.

Question 9

If a person has a low metabolic rate,they will:

Accepted Answer

A low metabolic rate means that the body burns fewer calories at rest, which can lead to excess calories being stored as fat. Therefore, the person will store excess energy as fat.

Question 10

"Whenever I am depressed or bored,I tend to eat even when I'm not hungry." This statement best illustrates the role of ____ in hunger.

Accepted Answer

The statement mentions that the person tends to eat when they are depressed or bored, indicating that their mood and personality factors play a role in their hunger. Option A (CCK) refers to a hormone that regulates hunger and satiety, option B (genetic factors) could certainly contribute to hunger, but this is not indicated in the statement. Option D (self-handicapping) refers to a cognitive strategy in which individuals deliberately sabotage their own performance or success, and is not relevant to hunger.

Question 11

"I really should not go to that all-you-can eat buffet.If I see food,I'll eat it." What psychosocial hunger factor does this self-awareness best represent?

Accepted Answer

This self-awareness reflects learned associations, as the person is aware of their tendency to overeat when presented with a buffet and recognizes the association between the presence of food and their behavior of eating it.

Question 12

It is believed that Troy has a high set point.Dieting will be difficult for him because:

Accepted Answer

A high set point means Troy's body will fight to maintain a certain weight, and when he diets, his body may slow down his metabolic rate to conserve energy, making it harder for him to lose weight. Hormonal imbalances and abnormal functioning of the hypothalamus can cause difficulties in feeling full and cause frequent hunger bouts, but the question does not provide any information that indicates this is the case for Troy. While susceptibility to learned eating cues may make it difficult for Troy to resist unhealthy food choices, it is not directly related to his set point.

Question 13

The only known ways to raise metabolic rates are:

Accepted Answer

The answer of The only known ways to raise metabolic...

Question 14

A person's metabolic rate refers to the:

Accepted Answer

A person's metabolic rate refers to the rate at which food is broken down into energy and how fast the energy is used. It includes all the chemical processes that occur within the body to maintain life, including breathing, digestion, and cellular activity. Metabolic rate is influenced by many factors, such as age, gender, muscle mass, and hormone levels.

Question 15

Question 18

Lara is so thin,yet she eats high-calorie foods and fatty foods.Based on information presented in the textbook,why can Lara stay so thin?

Accepted Answer

Lara likely has a gene that increases metabolism, allowing her body to efficiently burn the high-calorie and fatty foods she consumes. This genetic factor enables her to maintain her thin frame despite her diet.

Question 19

The Czech Republic has the highest death rate from heart disease.Module 15 argues that this is due to:

Accepted Answer

Module 15 suggests that the high death rate from heart disease in the Czech Republic is due to social-cultural factors such as a high consumption of fatty and salty food, high alcohol intake and smoking, as well as stress and lack of physical activity. Therefore, option A (social-cultural factors) is the best choice.

Question 20

"It's noon,so it's time to eat." This person illustrates the role of ____ in hunger.
