Question 1

Most obese people have leptin deficiency.​

Accepted Answer

While leptin deficiency can be a factor in some cases of obesity, it is not the case for most obese people. Obesity is a complex condition that can be caused by a variety of factors, including genetics, diet, lifestyle choices, and medical conditions.

Question 2

The theory that the body tends to maintain a certain weight by means of its own internal controls is referred to as the _____ theory.​

Accepted Answer

The theory that the body tends to maintain a certain weight by means of its own internal controls is referred to as the set-point theory. This choice best describes the concept outlined in the question. The other choices are not directly related to this theory.

Question 3

The psychological desire to eat is referred to as _____.​

Accepted Answer

Appetite refers to the psychological desire to eat, as opposed to hunger which is the physiological need for food. Satiety refers to the feeling of fullness and satisfaction after eating. Obesity is a medical condition characterized by excess body fat. Hypothalamism is not a recognized term in the field of nutrition or psychology.

Question 4

Fast food contributes to obesity because it generally provides _____.​

Accepted Answer

Fast food is typically energy-dense, meaning it contains a lot of calories in a small amount of food. This is due to the high levels of sugar, fat, and salt in most fast food choices, which can contribute to weight gain and obesity. Large portion sizes also make it easy to overeat and consume more calories than the body needs. Therefore, the best choice is D because it explains how fast food contributes to obesity.

Question 5

Which factor is an environmental stimulus that contributes to obesity?

Accepted Answer

An increase in meal portion sizes is an environmental stimulus that contributes to obesity by increasing the amount of calories consumed per meal. Consuming more calories than the body needs can lead to weight gain and ultimately obesity. Factors such as genetics and lipoprotein lipase enzyme levels may also contribute to obesity, but they are not environmental stimuli. Energy-poor fast food may contribute to obesity, but it is not the only factor and there are other dietary factors to consider as well. The year-round availability of fresh fruits and vegetables is actually a positive factor for overall health and is not a contributing factor to obesity.

Question 6

The question of whether a person should lose weight depends on _____.

Accepted Answer

The question of whether a person should lose weight depends on their individual weight status. Other factors, such as neighborhood, cost, FDA approval of drugs, and basal metabolic rate may be relevant to the weight loss process, but they do not determine whether a person should lose weight in the first place.

Question 7

Susie has been overweight for many years. She tends to eat when she is not really hungry and eats more food when she is angry or depressed. Which theory could explain Susie's problem of overweight?​

Accepted Answer

Susie's problem of overeating when she is not really hungry and eating more when she is angry or depressed is suggestive of a learned behavior rather than lipoprotein lipase or set-point theory. While genetics may play a role in susceptibility to obesity, it is not specific to Susie's behavior. Aggravated satiety syndrome is not a recognized theory for explaining overweight.

Question 8

Which scenario illustrates the best example of the link between food behavior and emotions?​

Accepted Answer

B) is the best example because it directly connects eating behavior with an emotional state (fear of rejection), illustrating how emotions can influence food choices and eating habits.

Question 9

Some research indicates that obese people have much more lipoprotein lipase activity in their fat cells than lean people do.​

Accepted Answer

Lipoprotein lipase is responsible for breaking down fat and storing it in fat cells. Therefore, obese individuals who have more fat cells also have more lipoprotein lipase activity in their fat cells, according to research. Lean individuals have less fat cells and therefore less lipoprotein lipase activity.

Question 10

The number of fat cells increases most rapidly _____.

Accepted Answer

The number of fat cells increases most rapidly during late childhood and early puberty. This is because during this time, the body is preparing for potential future pregnancies by increasing the number of fat cells available to store energy. The number of fat cells in the body remains somewhat constant after puberty, but their size can still grow if a person consistently eats more calories than they burn.

Question 11

A lean person's fasting blood level of ghrelin is typically higher than in an obese person.​

Accepted Answer

Ghrelin is a hormone that stimulates appetite and promotes energy storage. Studies have shown that fasting blood levels of ghrelin are higher in lean individuals compared to obese individuals. This is thought to be due to the body's adaptation to conserve energy in times of caloric deficiency by increasing appetite and consumption.

Question 12

On a sensible weight-control program, meals and snacks should include whole-grain foods and fiber-rich vegetables.

Accepted Answer

Whole-grain foods and fiber-rich vegetables are important components of a sensible weight-control program as they help to promote satiety, regulate blood sugar levels, and provide essential nutrients.

Question 13

Due to harmful effects reported by consumers, the over-the-counter amphetamine-like substance _____ was banned by the FDA.​

Accepted Answer

Ephedrine has been associated with serious cardiovascular events such as heart attack and stroke, leading to its being banned by the FDA. Pyruvate, chitosan, yohimbe, and Xenical do not have the same level of reported harmful effects and are still available over-the-counter or through prescription.

Question 14

Genetics influences the way the body consumes, stores, and spends energy.​

Accepted Answer

Genetics plays a significant role in the body's metabolism, which affects how energy is utilized, stored, and expended. Certain genetic variations can make a person more predisposed to weight gain, obesity, and other metabolic disorders.

Question 15

Health-promoting built environments may result in a healthier and leaner population.​

Accepted Answer

Health-promoting built environments, such as access to sidewalks, parks, and public transportation, have been shown to increase physical activity and decrease rates of obesity and chronic disease in communities. Therefore, it is true that health-promoting built environments may result in a healthier and leaner population.

Question 16

The hormone _____ is produced by stomach cells, and promotes positive energy balance by stimulating appetite and promoting efficient energy storage.​

Accepted Answer

Ghrelin is produced by cells in the stomach and stimulates appetite, promoting food intake and energy storage. Insulin is produced by the pancreas and helps to regulate blood glucose levels, while leptin is produced by fat cells and signals the brain to reduce appetite and increase energy expenditure. E and D are not hormones, lipase is an enzyme that helps break down fats, and ephedra is a plant used in traditional medicine.

Question 17

Ghrelin is a hormone produced in the stomach that acts much like leptin.​

Accepted Answer

Ghrelin and leptin have opposite effects; ghrelin stimulates appetite, while leptin decreases it. Ghrelin signals hunger to the brain, whereas leptin signals satiety.

Question 18

Herbal dietary supplements are automatically deemed safe because they are natural.​

Accepted Answer

Just because herbal dietary supplements are natural does not automatically make them safe. They may still have potential side effects or interactions with other medications or health conditions. It is important for individuals to do their research and consult with a healthcare provider before taking any herbal supplements.

Question 19

Genetics alone determines a person's susceptibility to obesity.​

Accepted Answer

While genetics can play a role in a person's predisposition to obesity, it is not the only factor. Other factors such as lifestyle, environment, and behavior also contribute to a person's weight.

Question 20

Television and sedentary video and computer entertainment contribute to obesity because they have mostly replaced outdoor activity for many people.​

Accepted Answer

Television and sedentary video and computer entertainment have replaced outdoor activity for many people, leading to a decrease in physical activity and an increase in obesity rates.
