Identify which step in the diagram each of the given statements is discussing. The first step has already been identified for you. Descriptions 1.) __ As part of the body's effort to heal the initial blood vessel damage, LDL accumulates in the vessel wall. The cholesterol in the LDL becomes oxidized. 2.) __ Once the monocytes enter the vessel wall, they enlarge and become macrophages. The macrophages engulf oxidized LDL until they become fat-packed cells called foam cells. When foam cells collect in the vessel wall, they begin to form a fatty streak. 3.) __ As the fatty streak grows, smooth muscle cells migrate from deeper inside the vessel wall to the interior surface of the vessel wall. These smooth muscle cells enlarge and contribute to the expanding plaque. 4.) _1_ An injury to the interior blood vessel wall triggers an inflammatory response. 5.) __ The bulging, mature plaque made of inflamed tissue and fatty deposits can grow so large that it obstructs the flow of blood. Sometimes the plaque is hardened by calcium deposits, which further limits the flexibility and blood flow of the blood vessel. 6.) __ Oxidized LDL in the vessel wall attracts white blood cells called monocytes, which enter the cell wall and increase the inflammatory response.

Ellen is a 55-year-old woman with multiple medical problems, including chronic back pain. She is 66 inches tall and weighs 286 pounds. She takes medications for high blood pressure and hypercholesterolemia, both of which are currently under control. She also takes pain medications every day and has difficulty walking, although she occasionally attends a water exercise class at the local sports center. She states that she has been overweight most of her life and confesses that foods, especially sweet foods, are a comfort to her when she experiences physical or emotional pain. Her diet history reveals an intake of two or three cans of ginger ale or root beer each day. Her usual meals with her husband include meat or chicken (she does not like fish) and vegetables, such as corn or potatoes. She snacks on several types of frozen desserts between meals. She enjoys milk on occasion but admits that it is not a part of her regular diet. A recent visit to her doctor reveals a weight gain of 15 pounds over the past six months and an increase in her fasting blood glucose level into the "pre-diabetes" range. She has no family history of diabetes. Her doctor has recommended she lose weight and make lifestyle changes to prevent her from developing diabetes. 6. If Ellen were to reduce her weight to a healthy level and maintain a BMI of between 18.5 and 24.9, how much of a blood pressure reduction would she likely achieve for each 10 kg she lost? a. 2 mm Hg b. 6 mm Hg c. 8 mm Hg d. 4 mm Hg e. 10 mm Hg

Fad diets often produce weight loss, at least initially, because they are designed to limit total kcalories to ________ kcalories or less per day.

1200

A person is overweight (350 pounds) and desires to lose 35 pounds over a 6-month period. The total kcalorie intake restriction required to reach the weight-loss goal is _______________. If the weight loss time period is 27 weeks, the weekly kcalorie restrictions to achieve the goal are _____________ and the daily kcalorie restrictions to achieve this goal are ___________.

122,500 kcalories 4,537 kcalories 648 kcalories To determine total kcalories in 35 pounds, multiply 35 pounds by 3,500 kcalories per pound to get 122,500 kcalories. To calculate the weekly kcalorie restriction to achieve the goal in 27 weeks, divide 112,500 kcalories by 27 weeks to get a 4,537-kcalorie deficit in 1 week. To calculate the daily kcalorie restriction to achieve the goal in 27 weeks, divide the weekly 4,537 kcalories by 7 days per week to get 648 kcalories per day. This means the person must eat 648 fewer kcalories everyday than is required to maintain his current weight of 350 pounds.

As little as ___ minutes per day of activity can add years to a person's life expectancy.

Rick is a healthy 19-year-old college student who is 70 inches tall and weighs 205 pounds. He has decided to "get a six-pack" over the summer with a diet and exercise program. As part of his new plan, he has stopped drinking soda and is eating more salads in addition to his usual diet. Besides of these changes, he is unclear on how to proceed to reach his fitness goal. Rick's mother wants to make sure his approach will not interfere with his normal growth and development, and has asked him to seek reliable information to help him make a reasonable plan. 8. If Rick wishes to reduce his BMI to 27, he needs to eat fewer kcalories than he expends. For an adolescent who carries excess fat, the recommended maximal weight loss is one pound per week. Since there are 3500 kcalories in a pound of body fat, a deficit of 3500 kcalories for the week or 500 kcalories per day would be required. Calculate the maximum number of kcalories Rick can consume per day to achieve a weight loss of one pound per week. Assume that his weight is 205 pounds and that his physical activity factor is "low active." a. 2710 kcalories b. 3533 kcalories c. 3192 kcalories d. 3033 kcalories e. 2692 kcalories

Differentiate among cancer initiators, promoters, and antipromoters and describe how nutrients or foods might play a role in each category.

Some dietary factors, such as alcohol and heavily smoked foods, may initiate cancer development; others, such as animal fats, may promote cancer once it has gotten started; and still others, such as fiber, antioxidant nutrients, and phytochemicals, may act as antipromoters that protect against the development of cancer. By eating many fruits, vegetables, legumes, and whole grains and reducing saturated fat intake, people obtain the best possible nutrition at the lowest possible risk. Minimizing weight gain through regular physical activity and a healthy diet is also beneficial.

SMART Goals

Specific—define goal clearly Measurable—track progress and measure outcomes Attainable—set a goal that is challenging, but still realistically achievable Relevant—confirm that goal is meaningful and fits lifestyle Time based—create a time frame with specific dates for beginning actions and accomplishing goals

Distinguish between body weight and body composition, including methods to assess each.

The BMI is based on weight relative to height and serves as a reliable indicator of chronic disease risks, but it says little about body composition. The ideal amount of body fat varies from person to person, but researchers have found that body fat in excess of 22 percent for young men and 27 percent for young women (the levels rise slightly with age) poses health risks. Central obesity is measured by waist circumference and indicates excess abdominal fat distributed around the trunk of the body. Central obesity contributes to chronic diseases and related deaths.

In aerobic cellular respiration, the cell needs oxygen in order to generate ATP. Aerobic exercise is exercise that primarily uses aerobic cellular respiration and thus requires a lot of oxygen. Anaerobic exercise uses primarily anaerobic cellular respiration in order to generate ATP, which does not require a lot of oxygen. The graph shows that, over the course of their workouts, Rosa uses a lot more oxygen than Deborah does. Thus, Rosa is doing an aerobic exercise, such as running, and Deborah is doing an anaerobic exercise, such as weightlifting.

The American College of Sports Medicine has issued three guidelines to develop and maintain fitness. The three guidelines include: Cardiorespiratory activity that uses large muscle groups and can be maintained continuously. These moderate intensity activities include running, cycling, swimming, and so on and should be performed 5 to 7 days per week for at least 30 minutes per day. Flexibility: This category involves stretching activities that use the major muscle groups. This activity should be performed 2 to 7 days/week at an intensity enough to feel tightness or slight discomfort. Yoga is an example of a stretching activity. Strength: This category involves resistance activities such as push-ups, weightlifting, and pilates. These activities should occur on 2 to 3 nonconsecutive days per week at an intensity such that muscle strength is enhanced and body composition is improved.

Type of Activity Aerobic activity that uses largemuscle groups and can be maintained continuously Resistance activity that is performed at a controlled speed and through a full range of motion Stretching activity that uses the major muscle groups Frequency 5 to 7 days per week 2 to 3 nonconsecutive days per week 2 to 7 days per week Intensity Moderate (equivalent to walking at a pace of 3 to 4 miles per hour) Enough to enhance muscle strength and improve body composition Enough to feel tightness or slight discomfort Duration At least 30 minutes per day 2 to 4 sets of 8 to 12 repetitions involving each major muscle group 2 to 4 repetitions of 15 to 30 seconds per muscle group Examples Running, cycling, dancing, swimming, inline skating, rowing, power walking, cross-country skiing, kickboxing, water aerobics, jumping rope; sports activities such as basketball, soccer, racquetball, tennis, volleyball Pull-ups, push-ups, sit-ups, weightlifting, pilates Yoga

Outline reasonable strategies for achieving and maintaining a healthy body weight.

A surefire remedy for obesity has yet to be found, although many people find a combination of approaches to be most effective. Diet and exercise shift energy balance so that more energy is expended than is taken in. Behavior modification and cognitive restructuring retrain habits to support a healthy eating and activity plan. Such a plan requires time, individualization, and sometimes the assistance of a registered dietitian nutritionist or support group.

To prepare for the cross-country meet, a skier decides to significantly increase the amount of carbohydrates in his diet (a technique also known as carbohydrate loading). Why might this be beneficial to the cross-country skier? Check all that apply. a. As long as oxygen is present, the glucose stored in the ingested carbohydrates can provide a steady stream of ATP, thus meeting the demands of prolonged periods of exercise. b. Carbohydrates are used to build actin filaments in the myofibrils, which increases muscle bulk and performance. c. Eating more carbohydrates leads to more glycogen stores in muscles, which then equates to larger energy stores for short, explosive bouts of energy use. d. The liver can store copious amounts of ingested carbohydrates as glycogen, which can then be slowly broken down to release the glucose needed to fuel aerobic respiration.

Summarize dietary recommendations to prevent chronic diseases.

Clearly, optimal nutrition plays a key role in keeping people healthy and reducing the risk of chronic diseases. To have the greatest impact possible, dietary recommendations are aimed at the entire population, not just at the individuals who might benefit most. Recommendations focus on weight control and urge people to limit saturated and trans fat; increase fiber-rich fruits, vegetables, legumes, and whole grains; and balance food intake with physical activity.

Fast-food restaurants have significantly contributed to the development of obesity for all of the following reasons except: a. A "supersize" portion of fries delivers more than 600 kcalories. b. Close proximity of fast-food establishments does not increase the risk of obesity. c. Energy-dense foods in combination with large portion sizes are offered. d. People buy large portions and combinations, perceiving them to be a great value. e. Portion sizes are currently two to eight times larger than standard serving sizes.

Close proximity of fast-food establishments does not increase the risk of obesity.

Sally is a 43-year-old mother of two who has gained 50 pounds over the past 5 years. She is 64 inches tall and weighs 180 pounds with a BMI of 30.8. Her waist circumference is 37 inches. She acknowledges that she is not as physically active as she would like to be. She also notes how recent stresses in her life have affected her sleep and seem to have triggered her appetite for sweets and comfort foods. Sally's father recently died from complications of type 2 diabetes, and her mother and sisters are overweight. Sally says she is very motivated to "not get diabetes" and is disturbed that her recent physical exam revealed mildly elevated blood pressure, glucose, and cholesterol levels. 8. Sally stated that she is sedentary. You need to convince her that in addition to following a diet featuring low-energy density foods, she also needs to incorporate 200-300 minutes of moderately intense physical activity per week. The benefits of combining diet and physical activity together include all of the following, except: a. Combining diet with exercise does not reduce stress, which is not helpful for those who respond to stress with inappropriate eating. b. Combining diet with exercise reduces abdominal obesity and improves blood pressure. c. Those who lost weight by diet and exercise retained more muscle compared to those who only followed a kcalorie-restricted diet. d. Those who lost weight by diet and exercise regained less weight compared to those who only followed a kcalorie-restricted diet. e. Those who lost weight by diet and exercise lost more body fat compared to those who only followed a kcalorie-restricted diet.

Combining diet with exercise does not reduce stress, which is not helpful for those who respond to stress with inappropriate eating.

Compare the dietary strategies to manage type 1 diabetes with those to prevent and treat type 2 diabetes.

Diabetes is characterized by high blood glucose and insufficient insulin, ineffective insulin, or a combination of the two. People with type 1 diabetes coordinate diet, insulin, and physical activity to help control their blood glucose. Those with type 2 diabetes benefit most from a diet and physical activity program that controls glucose fluctuations and promotes weight loss.

Kaitlyn F. is a 21-year-old woman who weighs 121 pounds. She has taken up running in an effort to lose weight and improve her endurance. She runs 3 to 4 days a week for approximately 45 minutes to an hour. At the store, she finds a sports "energy gel" labeled as a "natural performance enhancer." Each 1.1-ounce package provides 100 kcalories, 40 milligrams sodium, 30 milligrams potassium, and 25 grams total carbohydrates. The directions read: "For best results, consume one package 15 minutes before activity, one to two packages per hour during activity and one package immediately after activity to aid in recovery. Always follow consumption with water." Kaitlyn is trying to determine whether she needs this product for her training regimen. 3. To avoid potential dehydration, which guideline would be best for Kaitlyn to maintain hydration during her activity? a. After the activity, she needs to drink the total amount required to replace fluid lost all at one time. b. Drink 4 oz of water plus the energy gel every 15 minutes during the first hour of the activity. c. Drink 9 oz of water 2 hours prior to the activity. d. Drink 16 oz of water 4 hours prior to the activity. e. Drink 4 oz of water every 15 minutes during the first hour of activity.

Discuss the physical, social, and psychological consequences of overweight and obesity.

The question of whether a person should lose weight depends on many factors: among them are the extent of overweight, age, health, and genetic makeup. Not all obesity will cause disease or shorten life expectancy. Just as there are unhealthy, normal-weight people, there are healthy, overweight people. Some people may risk more in the process of losing weight than in remaining overweight. Fad diets and weight-loss supplements can be as physically and psychologically damaging as excess body weight.

An individual who has an apple shape means they likely have higher levels of visceral or central adiposity. High levels of visceral fat are correlated with increased risk of chronic disease, including type 2 diabetes and cardiovascular disease. T/F

Identify the factors that influence fuel use during physical activity and the types of activities that depend more on glucose or fat, respectively.

The mixture of fuels the muscles use during physical activity depends on diet, the intensity and duration of the activity, and training. During intense activity, the fuel mix contains mostly glucose, whereas during less intense, moderate activity, fat makes a greater contribution. With endurance training, muscle cells adapt to store more glycogen and to rely less on glucose and more on fat for energy. Athletes in training may need more protein than sedentary people do, but they typically eat more food as well and therefore obtain enough protein without taking supplements.

Present strategies to lower blood pressure.

The most effective dietary strategy for preventing hypertension is weight control. Also beneficial are diets rich in fruits, vegetables, nuts, and low-fat milk products and low in fat, saturated fat, and sodium.

Discuss some of the physical, emotional, and environmental influences on food intake.

A mixture of signals governs a person's eating behaviors. Hunger and appetite initiate eating, whereas satiation and satiety stop and delay eating, respectively. Each responds to messages from the nervous and hormonal systems. Superimposed on these signals are complex factors involving emotions, habits, and other aspects of human behavior.

List the components of energy expenditure and factors that might influence each.

A person in energy balance takes in energy from food and expends much of it on basal metabolism, some of it on physical activities, and a little on the thermic effect of food. Energy requirements vary from person to person, depending on such factors as gender, age, weight, and height as well as the intensity and duration of physical activity. All of these factors must be considered when estimating energy requirements.

Environmental temperature effect on BMR

Both heat and cold raise the BMR.

A bomb calorimeter can estimate the potential energy value of foods. a. True b. False

False

Because body weight and body fat correlate with disease risk and life expectancy, obese people are destined to die prematurely. a. True b. False

False

For a typical healthy adult, physical activity accounts for the largest share of total energy expended each day. a. True b. False

False

People who are overweight are, by necessity, overfat. a. True b. False

False

The basal metabolic rate rises with a loss of lean body mass and during fasting and malnutrition. a. True b. False

False

The resting metabolic rate is measured while a person is sleeping. a. True b. False

False

Fasting/starvation effect on BMR

Fasting/starvation lowers the BMR. Prolonged starvation reduces the total amount of metabolically active lean tissue in the body, although the decline occurs sooner and to a greater extent than body losses alone can explain. More likely, the neural and hormonal changes that accompany fasting are responsible for changes in the BMR.

Height effect on BMR

In tall, thin people, the BMR is higher. If two people weigh the same, the taller, thinner person will have the faster metabolic rate, reflecting the greater skin surface, through which heat is lost by radiation, in proportion to the body's volume (see Figure 8-5).

Stresses effect on BMR

Stresses (including many diseases and certain drugs) raise the BMR.

A healthy body contains enough lean tissue to support health and the right amount of fat to meet body needs. T/F

It feels like work and it may make you tired, but studying requires only one or two kcalories per minute. T/F

Regardless of hunger, people typically overeat when offered the abundance and variety of a buffet. To limit unhealthy weight gains, listen to hunger and satiety signals. T/F

Body composition (gender) effect on BMR

The more lean tissue, the higher the BMR (which is why males usually have a higher BMR than females). The more fat tissue, the lower the BMR.

Identify relationships between body weight and chronic diseases.

The weight appropriate for an individual depends largely on factors specific to that individual, including body fat distribution, family health history, and current health status. At the extremes, both overweight and underweight carry clear risks to health.

A reasonable initial target for most overweight people is a BMI 2 units below their current one. To determine a goal weight based on a desired BMI, locate your height in the first column and then look across the row until you reach the column with the desired BMI at the top. T/F

True

Even adults who maintain a healthy weight can develop type 2 diabetes. a. True b. False

True

If a person consistently eats 2000 kcalories a day but only expends 1800 kcalories each day, he/she will gain weight. a. True b. False

True

Regardless of body weight, being active is healthier than being sedentary. T/F

True

Satiety is a feeling of fullness and reminds us to "not start eating again." a. True b. False

True

Smoking is the leading cause of preventable illnesses and early deaths. Obesity is a close second. A BMI of 40 or greater is equivalent to a lifetime of smoking, representing 10 years' loss of life. T/F

True

The abundance of available food is one example of an environmental influence that often makes people keep eating after they are full. a. True b. False

True

The thermic effect of food is the amount of energy the body uses to chew, swallow, and digest a meal. a. True b. False

True

This J-shaped curve describes the relationship between body mass index (BMI) and mortality and shows that both underweight and overweight present risks of a premature death. T/F

True

Upper-body fat is more common in men thn in women and may be more closely associated with chronic diseases. T/F

True

Describe energy balance and the consequences of not being in balance.

When energy consumed equals energy expended, a person is in energy balance and body weight is stable. If more energy is taken in than is expended, a person gains weight. If more energy is expended than is taken in, a person loses weight.

hypothalamus

a brain center that controls activities such as maintenance of water balance, regulation of body temperature, and control of appetite.

metabolic syndrome

a combination of risk factors—elevated fasting blood glucose, hypertension, abnormal blood lipids, and abdominal obesity—that greatly increase a person's risk of developing heart disease.

normal-weight obesity syndrome

a condition characterized by excess body fat, an adequate BMI, and increased risk factors for chronic diseases.

Physiological functions - Consequences of Relative Energy Deficiency

altered hormone activities anemia bone loss decreased glycogen stores decreased protein synthesis impaired metabolism menstrual dysfunction poor growth

waist circumference

an anthropometric measurement used to assess a person's abdominal fat

thermic effect of food (TEF)

an estimation of the energy required to process food (digest, absorb, transport, metabolize, and store ingested nutrients); also called the specific dynamic effect (SDE) of food or the specific dynamic activity (SDA) of food. The sum of the TEF and any increase in the metabolic rate due to overeating is known as diet-induced thermogenesis (DIT).

inflammation

an immunological response to cellular injury characterized by an increase in white blood cells.

bomb calorimeter

an instrument that measures the heat energy released when foods are burned, thus providing an estimate of the potential energy (kcalories) of the foods. calor = heat metron = measure

orthorexia nervosa

an obsession with good nutrition to improve health that is characterized by restrictive diets, ritualized patterns of eating, and rigid avoidance of foods believed to be unhealthy.

BMR

basal metabolic rate

stress fractures

bone damage or breaks caused by stress on bone surfaces during exercise.

eating disorder

disturbances in eating behavior that jeopardize a person's physical or psychological health.

disordered eating

eating behaviors that are neither normal nor healthy, including restrained eating, fasting, binge eating, and purging.

central obesity

excess fat around the trunk of the body; also called abdominal fat or upper-body fat.

ectopic fat

excess fat in locations other than adipose tissue.

Subcutaneous fat

fat stored directly under the skin. sub = beneath cutaneous = skin

visceral fat

fat stored within the abdominal cavity in association with the internal abdominal organs; also called intra-abdominal fat.

kilojoules (a measure of work energy)

resting metabolic rate (RMR)

similar to the basal metabolic rate (BMR), a measure of energy use for a person at rest in a comfortable setting, but with less stringent criteria for recent food intake and physical activity. Consequently, the RMR is easier to determine, but slightly higher than the BMR.

cutaneous =

skin

Common Methods Used to Asses Body Fat

skinfold measures hydrodensitometry bioelectrical impedance air-displacement plethysmography dual-energy X-ray absorptiometry (DEXA) waist circumference

insulin resistance

the condition in which a normal amount of insulin produces a subnormal effect in muscle, adipose, and liver cells, resulting in an elevated fasting glucose; a metabolic consequence of obesity that precedes type 2 diabetes.

energy balance

the energy (kcalories) consumed from foods and beverages compared with the energy expended through metabolic processes and physical activities.

basal metabolism

the energy needed to maintain life when a body is at complete digestive, physical, and emotional rest.

satiation

the feeling of satisfaction and fullness that occurs during a meal and halts eating. Satiation determines how much food is consumed during a meal.

thermogenesis

the generation of heat; used in physiology and nutrition studies as an index of how much energy the body is expending.

Appetite

the integrated response to the sight, smell, thought, or taste of food that initiates or delays eating.

physiological fuel value

the number of kcalories that the body derives from a food, in contrast to the number of kcalories determined by calorimetry.

hunger
