Health psychologists are LEAST likely to work with people who
- A.
Have anorexia nervosa
- B.
Over eat
- C.
Have bulimia
- D.
Have inadequate nutrition
Correct Answer
D. Have inadequate nutritionExplanation
Health psychologists are least likely to work with people who have inadequate nutrition because their primary focus is on the psychological aspects of health and well-being. While anorexia nervosa, overeating, and bulimia are all eating disorders that can have psychological components, inadequate nutrition is a broader issue that may be caused by various factors such as poverty, lack of access to food, or medical conditions. Health psychologists typically work with individuals who have specific psychological issues or disorders, and inadequate nutrition may require a different type of intervention or treatment approach that falls outside their scope of practice.Rate this question:

Rhythmic contraction and relaxation of the circular muscles that propel food through the digestive system is known as
- A.
The esophagus
- B.
Peristalsis
- C.
Voluntary digestion
- D.
Acidic flow
Correct Answer
B. PeristalsisExplanation
Peristalsis refers to the rhythmic contraction and relaxation of the circular muscles that push food through the digestive system. It is a crucial process that allows for the movement of food from the esophagus to the stomach and through the intestines. The term "esophagus" refers to the muscular tube that connects the throat to the stomach and does not specifically describe the contraction and relaxation of circular muscles. "Voluntary digestion" is not a recognized term, and "acidic flow" does not accurately describe the process of moving food through the digestive system. Therefore, the correct answer is peristalsis.Rate this question:

______ levels fall when fat stores fall, which may provide a long-term signal to eat more.
- A.
Leptin
- B.
Grhelin
- C.
Cholecystokinin (CCK)
- D.
Ventromedial
Correct Answer
A. LeptinExplanation
Leptin levels fall when fat stores fall, which may provide a long-term signal to eat more. Leptin is a hormone produced by fat cells that helps regulate energy balance by inhibiting hunger. When fat stores decrease, leptin levels decrease, signaling the brain to increase food intake and restore fat stores. This mechanism ensures that the body maintains a stable weight and prevents excessive weight loss.Rate this question:

Production of the peptide hormone CCK results in
- A.
Feelings of satiation
- B.
Feeling of hunger
- C.
A need to engage in physical activity
- D.
Depression, anxiety, and loss of energy
Correct Answer
A. Feelings of satiationExplanation
The production of the peptide hormone CCK results in feelings of satiation. CCK, or cholecystokinin, is released by cells in the small intestine in response to the presence of food. It acts as a signal to the brain to reduce appetite and increase feelings of fullness, thus promoting satiety. This hormone plays a crucial role in regulating food intake and can help prevent overeating.Rate this question:

The relationships between eating and weight maintenance is best described by which of the following statements?
- A.
Weight gain is proportional to overeating
- B.
A person who eats more than 3,000 calories per day will gain weight
- C.
Metabolic rate is a factor in weight maintenance
- D.
Fat people eat fewer calories per day than do thin people
Correct Answer
C. Metabolic rate is a factor in weight maintenanceExplanation
Metabolic rate refers to the rate at which our body burns calories to maintain basic bodily functions. This statement suggests that metabolic rate plays a role in weight maintenance, indicating that individuals with a higher metabolic rate may have an easier time maintaining their weight compared to those with a lower metabolic rate. It implies that weight gain or loss is not solely determined by the number of calories consumed but also by the body's ability to burn those calories efficiently.Rate this question:

When the participants in the study on experimental starvation were re-fed at the end of the starvation phase of the experiment,
- A.
Many of them gained more weight than they had lost
- B.
Most of them were not able to regain lost weight
- C.
They became more cheerful and optimistic than they had been prior to the starvation phase
- D.
They no longer had much interest in food.
Correct Answer
A. Many of them gained more weight than they had lostExplanation
During the starvation phase of the experiment, the participants were deprived of food, causing their bodies to enter a state of starvation. When they were re-fed at the end of this phase, their bodies may have experienced a rebound effect, leading to an increased appetite and a tendency to overeat. This could explain why many of them gained more weight than they had lost during the starvation phase.Rate this question:

Carl is five feet, 10 inches tall, has a medium frame, and weights 154 pounds. In other words, Carl is about in the middle of the ideal weight range according to the Metropolitan Life Insurance Company's desirable weight charts. This means that Carl
- A.
Has a healthy waist-to-hip ratio
- B.
Needs to gain a few pounds
- C.
Should try to lose a few pounds
- D.
None of the above
Correct Answer
D. None of the aboveExplanation
The information provided about Carl's height, frame, and weight suggests that he falls within the ideal weight range according to the Metropolitan Life Insurance Company's desirable weight charts. Therefore, it can be inferred that Carl does not need to gain or lose weight, and his waist-to-hip ratio is not specified in the given information. Hence, the correct answer is "none of the above".Rate this question:

The skinfold technique and bioelectrical impedance are ways to measure
- A.
Utilization of glucose by adipose tissue
- B.
Percentage of body fat
- C.
Metabolic activity of fat
- D.
Ratio of height to body weight
Correct Answer
B. Percentage of body fatExplanation
The skinfold technique and bioelectrical impedance are both methods used to measure body composition. These methods estimate the percentage of body fat by measuring the thickness of skinfolds at various sites on the body or by analyzing the electrical conductivity of body tissues. Therefore, the correct answer is "percentage of body fat".Rate this question:

Throughout most of history, being plump or fat
- A.
Was a sign of laziness
- B.
Was a mark of prosperity
- C.
Was a sign of poor health
- D.
Characterized working class people
Correct Answer
B. Was a mark of prosperityExplanation
Being plump or fat being a mark of prosperity can be explained by historical context. In many cultures, especially in times of scarcity, having enough food to eat and being able to afford indulgence in rich, calorie-dense foods was a luxury that only the wealthy could afford. Therefore, being plump or fat was seen as a symbol of wealth and abundance. This perception changed over time as societal attitudes towards body image shifted, but historically, a larger body size was associated with prosperity.Rate this question:

During the past 20 years, Americans have reduced the percent of calories obtained from dietary fat, and
- A.
They have become thinner
- B.
They have increased their sugar consumption
- C.
They have decreased their fast food consumption
- D.
Their average weight has remained the same
Correct Answer
B. They have increased their sugar consumptionExplanation
Americans have reduced the percent of calories obtained from dietary fat over the past 20 years. However, despite this decrease in fat consumption, they have not become thinner or decreased their fast food consumption. Additionally, the answer "their average weight has remained the same" contradicts the statement that Americans have become thinner. Therefore, the only logical explanation left is that Americans have increased their sugar consumption.Rate this question:

How does setpoint influence metabolism during a period of severe food restriction?
- A.
It increases metabolism
- B.
It decreases metabolism
- C.
It does not influence metabolism
- D.
It increases metabolism in the beginning but decreases metabolism if the food restriction continues
Correct Answer
B. It decreases metabolismExplanation
During a period of severe food restriction, the body enters a state of energy conservation to cope with the limited food supply. This is achieved by decreasing metabolism, as the body tries to conserve energy by slowing down various processes. This decrease in metabolism helps the body to survive with fewer calories and maintain essential functions.Rate this question:

The results of the studies on experimental starvation and experimental overeating
- A.
Indicate that eating is a learned behavior
- B.
Suggest that eating is always pleasurable
- C.
Are consistent with the concept of setpoint
- D.
Show that eating is relatively unimportant in the lives of most people
Correct Answer
C. Are consistent with the concept of setpointExplanation
The results of the studies on experimental starvation and experimental overeating being consistent with the concept of setpoint means that they support the idea that our bodies have a natural weight range or setpoint that they strive to maintain. These studies suggest that when we deviate from this setpoint by either starving ourselves or overeating, our bodies will try to compensate and return to our original weight. This supports the notion that eating is regulated by our body's internal mechanisms rather than being solely driven by external factors.Rate this question:

- A.
S-shaped
- B.
U-shaped
- C.
Direct-the heavier the person, the greater the risk for poor health
- D.
Inverse- the heavier the person, the lower the risk for poor health
Correct Answer
B. U-shapedExplanation
The relationship between weight and poor health is U-shaped. This means that both being underweight and overweight can increase the risk for poor health. There is an optimal range of weight where the risk for poor health is lowest, and individuals who fall outside this range are more likely to experience health problems.Rate this question:

Correct Answer
C. Reinforce healthy eating habitsExplanation
Behavior modification programs for weight control typically focus on reinforcing healthy eating habits. This means that these programs aim to encourage and reward individuals for making healthier food choices and adopting better eating habits. By reinforcing positive behaviors, such as consuming nutritious foods and practicing portion control, individuals are more likely to maintain a healthy weight and overall lifestyle. Punishing unhealthy eating habits or weight gain may not be as effective in the long term, as it can lead to negative associations and potential disordered eating patterns. Therefore, reinforcing healthy eating habits is a more beneficial approach for weight control programs.Rate this question:

Which of these is the most effective combination for substantial weight loss during dieting and maintaining weight loss after 1 year?
- A.
Fat suctioning and liquid protein diet
- B.
Prescription amphetamines and nonprescription phenylpropylaimine
- C.
Low-calorie diet and increased physical activity
- D.
High carbohydrate diet and psychoanalysis
Correct Answer
C. Low-calorie diet and increased physical activityExplanation
A low-calorie diet and increased physical activity are the most effective combination for substantial weight loss during dieting and maintaining weight loss after 1 year. A low-calorie diet helps to create a calorie deficit, which is necessary for weight loss, while increased physical activity helps to burn more calories. This combination promotes both healthy eating habits and an active lifestyle, which are key factors in achieving and maintaining weight loss. Fat suctioning and liquid protein diet, prescription amphetamines and nonprescription phenylpropylaimine, and high carbohydrate diet and psychoanalysis are not supported by scientific evidence as effective methods for sustainable weight loss.Rate this question:

Experimental starvation
Correct Answer
C. OvereatingExplanation
Overeating is the most prevalent eating problem in the US because it refers to the act of consuming more food than necessary, often leading to weight gain and obesity. This issue is widespread due to various factors such as easy access to high-calorie foods, sedentary lifestyles, emotional eating, and cultural norms that promote large portion sizes. In contrast, anorexia nervosa and bulimia are eating disorders characterized by restrictive eating and unhealthy behaviors, affecting a smaller percentage of the population. Experimental starvation is not a commonly recognized eating problem, making overeating the most prevalent issue in the US.Rate this question:
