All 98 cards
Card 1
Define 'overweight' as described in the context of nutrition problems.
Overweight refers to having extra body weight, which can include bone, muscle, body fat, or body water. It is a widespread nutrition problem, often preceding obesity.
Card 2
What is the definition of 'obesity' according to the provided lecture outline?
Obesity is a condition characterized by excessive and unhealthy amounts of body fat. It is considered a widespread nutrition problem that has reached epidemic proportions in the United States.
Card 3
Explain the concept of Body Mass Index (BMI) and its primary purpose.
BMI is a numerical value that reflects body weight adjusted for height. Its primary purpose is to classify individuals into categories related to body weight, such as underweight, healthy weight, overweight, and obese.
Card 4
Distinguish between 'fat-free mass' and 'total body fat' in terms of body composition.
Fat-free mass (lean mass) includes body water, mineral-rich tissues (like bones and teeth), and protein-rich tissues (like muscles and organs). Total body fat consists of adipose tissue and essential fat found in cell membranes, certain bones, and nervous tissue.
Card 5
What is 'adipose tissue' and what are its specialized cells responsible for?
Adipose tissue consists of specialized cells that store triglycerides. These cells remove excess fat from the bloodstream for storage when food is plentiful and release fat for other cells to use as fuel when the body needs energy.
Card 6
How does overeating, especially in adulthood, impact adipose cells?
Overeating, particularly in adulthood, can lead to the development of new adipose cells. Once formed, existing fat cells generally remain unless they die or are surgically removed.
Card 7
What are the roles of proteins secreted by adipose cells?
Adipose cells secrete proteins that play various roles, including the regulation of food intake, glucose metabolism, and immune response. These secretions are crucial for maintaining overall body homeostasis.
Card 8
Differentiate between 'subcutaneous fat' and 'visceral fat' based on their location and characteristics.
Subcutaneous fat is stored under the skin, insulating the body from cold temperatures and padding it. Visceral fat, on the other hand, consists of fat deposits in the omentum under the abdominal muscles, and it makes substances that cause inflammation, increasing the risk of type 2 diabetes and CVD.
Card 9
Which type of body fat, subcutaneous or visceral, is more commonly associated with inflammatory factors and increased health risks?
Visceral fat is more commonly associated with inflammatory factors that may increase the risk of type 2 diabetes and cardiovascular disease (CVD). This is because it makes substances that cause inflammation.
Card 10
Why is measuring body fat important, and can it be measured directly?
Measuring body fat is important because the relative proportions of body fat to fat-free mass are predictive of the risk for obesity-related diseases. However, body fat cannot be measured directly; several indirect methods are used.
Card 11
Which of the following body composition measurement methods is described as highly accurate but also expensive and impractical? A) Skinfold thickness B) Bioelectrical impedance C) Air displacement (BOD POD) D) Underwater weighing
C) Air displacement (BOD POD). The source notes state that the BOD POD method is highly accurate but also expensive and impractical.
Card 12
What is the primary principle behind 'underwater weighing' for measuring body fat?
The primary principle behind underwater weighing is the comparison of a person's weight on land to their weight under water to determine body density. Lean tissue is denser than fat, so a person with more body fat will weigh less underwater.
Card 13
What is a key advantage and a key limitation of Dual-energy X-ray absorptiometry (DXA) for measuring body fat?
A key advantage of DXA is its accuracy in scanning the entire body's internal structures, including fat, with a low dose of radiation. A key limitation is that it is very expensive and not widely available.
Card 14
How does 'bioelectrical impedance' estimate body fat percentage?
Bioelectrical impedance estimates body fat percentage by measuring the rate of conduction of a weak electrical current through the body. Lean tissue, with its high water and electrolyte content, has high conductivity, while fat tissue has lower conductivity.
Card 15
What is a significant limitation of the 'skinfold thickness' method for estimating body fat?
A significant limitation of the skinfold thickness method is that its accuracy depends heavily on the skill of the technician. Additionally, it may underestimate body fat when used on overfat subjects.
Card 16
According to Table 10.3, what is considered a 'healthy weight' range for body fat percentage in men and women?
For men, a healthy weight is classified as 12–21% body fat, while for women, it is 23–31% body fat. Women generally require more body fat for optimal hormonal and reproductive health.
Card 17
Why do women generally require more body fat than men for optimal health?
Women require more body fat than men for optimal hormonal and reproductive health. This additional fat is essential for various physiological functions specific to the female body.
Card 18
Define 'energy' in the context of living things.
Energy, in the context of living things, is defined as the capacity to perform work. It exists in several forms, including heat, mechanical, chemical, and electrical energy, and can be stored, released, moved, or transformed.
Card 19
Which macronutrients and other substances yield energy for the body?
The macronutrients carbohydrates, fat, and protein, along with alcohol, yield energy for the body. Under most circumstances, carbohydrates and fat are the primary energy sources.
Card 20
How much of the energy released from macronutrients is stored in ATP, and what happens to the remaining energy?
About 40% of the energy released from macronutrients is stored in adenosine triphosphate (ATP) and related compounds. The remaining energy is released as heat.
Card 21
Define 'metabolism' and distinguish between anabolic and catabolic reactions.
Metabolism refers to all chemical reactions that constantly occur in living cells. Anabolic reactions require energy to build complex molecules, while catabolic reactions release energy by breaking down complex molecules.
Card 22
What is 'basal metabolism' and what vital activities does it support?
Basal metabolism is the minimal number of calories the body uses for vital physiological activities after fasting and resting for 12 hours. These activities include breathing, circulation, and organ function, representing the majority of the body's total energy expenditure.
Card 23
How does 'Resting Metabolic Rate (RMR)' differ from 'Basal Metabolic Rate (BMR)'?
Resting Metabolic Rate (RMR) is the body's rate of energy usage a few hours after resting and eating. It is slightly higher than Basal Metabolic Rate (BMR), which is the rate of energy use after fasting and resting for 12 hours.
Card 24
Which of the following factors does NOT influence metabolic rate? A) Thyroid hormone activity B) Body composition (lean body mass vs. fat tissue) C) Hair color D) Age
C) Hair color. The source notes list thyroid hormone, body composition, gender, body surface area, and age as factors influencing metabolic rate, but not hair color.
Card 25
Explain how gender and age influence metabolic rate.
Men generally have higher metabolic rates than women due to differences in lean body mass. Age also influences metabolic rate, primarily due to the loss of lean mass; a woman's BMR declines 2% per decade, and a man's BMR declines 3% per decade, though regular exercise can help mitigate this decline.
Card 26
Distinguish between 'Basal metabolism' and 'Resting metabolic rate (RMR)'.
Basal metabolism is the minimal number of calories the body uses for vital physiological activities after fasting and resting for 12 hours. Resting metabolic rate (RMR) is the body's rate of energy usage a few hours after resting and eating, and it is typically slightly higher than the basal metabolic rate (BMR).
Card 27
What is the primary function of ATP in energy metabolism?
About 40% of the energy released from macronutrients is stored in adenosine triphosphate (ATP) and related compounds. ATP serves as the main energy currency for cells, powering various cellular processes and reactions.
Card 28
How does hyperthyroidism affect an individual's metabolic rate?
Hyperthyroidism, an overactive thyroid gland, increases an individual's metabolic rate. This means the body uses more energy at rest, which can lead to symptoms like weight loss, increased heart rate, and sensitivity to heat.
Card 29
What is the primary reason men generally have higher metabolic rates than women?
Men generally have higher metabolic rates than women primarily due to differences in lean body mass. Lean body mass is more metabolically active than fat tissue, and men typically have a greater proportion of lean mass.
Card 30
A 45-year-old woman weighs 60 kg. Estimate her Basal Metabolic Rate (BMR) in kcal/day.
To estimate her BMR, we use the formula for women: 0.9 kcal/kg/hr. So, (0.9 kcal/kg/hr) * (60 kg) * (24 hr/day) = 1296 kcal/day. Her estimated BMR is 1296 kcal/day.
Card 31
Define 'Thermic effect of food (TEF)'.
The thermic effect of food (TEF) is the energy needed to digest, absorb, and metabolize nutrients from foods and beverages. It typically accounts for 5-10% of total caloric intake.
Card 32
What is 'Nonexercise activity thermogenesis (NEAT)' and provide examples.
Nonexercise activity thermogenesis (NEAT) refers to the energy expended for involuntary skeletal muscle activity. Examples include shivering, fidgeting, and maintaining muscle tone and posture, which can contribute significantly to daily calorie expenditure.
Card 33
A person consumes 2500 kcal per day. If their TEF is 8% of their total caloric intake, how many kcal are expended due to TEF?
The energy expended due to TEF is 8% of 2500 kcal. Calculation: 0.08 * 2500 kcal = 200 kcal. Therefore, 200 kcal are expended due to the thermic effect of food.
Card 34
Define 'Energy equilibrium'.
Energy equilibrium is a state where calorie intake from food and beverages equals calorie output for basal metabolism, physical activity, and the thermic effect of food. In this state, an individual's body weight remains constant.
Card 35
Which of the following describes a 'Negative energy balance'? A) Calorie intake equals calorie expenditure. B) Calorie intake is greater than calorie expenditure. C) Calorie intake is less than calorie expenditure. D) Energy is stored as ATP.
C) Calorie intake is less than calorie expenditure. A negative energy balance occurs when the body expends more calories than it consumes, leading to weight loss.
Card 36
What is the formula for calculating Body Mass Index (BMI)?
The formula for calculating BMI is: Weight (lb) / [Height (in)]^2 x 703. This calculation provides a general indicator of body fatness for most people.
Card 37
Why might BMI classifications not be appropriate for very muscular individuals?
BMI classifications may not be appropriate for very muscular individuals because muscle has a higher density than fat. A very muscular person might have a high BMI, classifying them as overweight or obese, despite having a healthy body composition with low body fat.
Card 38
Which body fat distribution is associated with an increased risk for cardiovascular disease and type 2 diabetes?
Upper-body ("apple" shape) fat distribution is associated with an increased risk for cardiovascular disease (CVD) and type 2 diabetes (diabesity). This pattern is more common among men but also occurs in women.
Card 39
A man has a waist circumference of 42 inches. What health risk is associated with this measurement?
A waist circumference greater than 40 inches for men is associated with increased health risks. Therefore, this man has an increased risk for health problems such as cardiovascular disease and type 2 diabetes.
Card 40
Define 'Hunger' and 'Satiety'.
Hunger is the physical discomfort that drives a person to consume food, signaling a physiological need for energy. Satiety is the sense that enough foods and beverages have been consumed to satisfy hunger, leading to a cessation of eating.
Card 41
Which hormone, secreted by the stomach, stimulates hunger?
Ghrelin, a hormone secreted from the stomach, stimulates hunger. It acts on the hypothalamus in the brain to signal the need for food intake.
Card 42
How does Leptin influence eating behavior and fat storage?
Leptin, a hormone secreted by adipose tissue, reduces hunger and inhibits fat storage. It signals to the brain about the body's energy stores, helping to regulate long-term energy balance.
Card 43
What is 'intestinal dysbiosis' and how is it related to diet?
Intestinal dysbiosis is an unhealthy imbalance of various kinds of gut microbiota in the intestinal tract. It is often associated with a typical Western diet, which is low in fiber and high in fat, animal protein, and added sugars.
Card 44
What is the impact of consuming ultra-processed foods on calorie intake?
Consumption of ultra-processed foods may stimulate excess calorie intake. These foods are often energy-dense, palatable, and can disrupt satiety signals, leading to overconsumption.
Card 45
Which of the following factors is NOT considered a physiological factor influencing hunger and satiety? A) Ghrelin secretion B) Leptin resistance C) Gut microbiota composition D) Cultural food preferences
D) Cultural food preferences. Ghrelin secretion, leptin resistance, and gut microbiota composition are all physiological factors related to hunger and satiety. Cultural food preferences are external, environmental factors.
Card 46
According to the provided notes, what percentage of body fat is considered 'Overweight' for women?
For women, 32-37% body fat is classified as 'Overweight'. This range indicates a higher proportion of body fat than considered healthy for optimal well-being.
Card 47
A 30-year-old man has 28% body fat. How would his body weight be classified based on percentage body fat?
According to the classification, 28% body fat for a man falls into the 'Obese' category (26-31%). This indicates a significant amount of excess body fat.
Card 48
What are two protective benefits of some extra fat for older adults?
For older adults, some extra fat can be protective by supplying an energy reserve in times of illness and by protecting the body from injury. These benefits can be crucial during periods of reduced food intake or increased fragility.
Card 49
Define 'intestinal dysbiosis' and explain its association with the typical Western diet.
Intestinal dysbiosis refers to an unhealthy imbalance of various kinds of gut microbiota. The typical Western diet, which is low in fiber and high in fat, animal protein, and added sugars, is strongly associated with causing this imbalance.
Card 50
How do short-chain fatty acids (SCFAs) like butyrate, propionate, and acetate contribute to energy metabolism after gut microbiota fermentation?
After gut microbiota ferment undigested carbohydrates, particularly dietary fiber, they produce SCFAs. Butyrate is primarily used by colon cells for energy, while propionate and acetate are absorbed and metabolized by the liver for energy.
Card 51
Which hormone, secreted from the stomach, is responsible for stimulating hunger and affecting the hypothalamus?
Ghrelin is the hormone secreted from the stomach that stimulates hunger. It acts on the hypothalamus to signal the body's need for food.
Card 52
Distinguish between the roles of Peptide YY and Cholecystokinin (CCK) in regulating satiety.
Peptide YY, from the small and large intestines, signals satiety to the hypothalamus and reduces ghrelin secretion. Cholecystokinin (CCK), from the small intestine, also suppresses appetite by affecting the hypothalamus.
Card 53
What is leptin's primary role in eating behavior, and what happens in individuals who are obese regarding its signal?
Leptin reduces hunger and inhibits fat storage. In individuals who are obese, there is often resistance to leptin's signal, meaning the body does not respond effectively to its hunger-reducing effects.
Card 54
What is 'thrifty metabolism' and how might it have been advantageous in the past versus its impact in modern society?
Thrifty metabolism refers to the efficiency of storing excess kilocalories as fat. Historically, this trait enhanced survival during famine, but in today's environment of readily available calorie-dense foods, it promotes overweight and obesity.
Card 55
According to the set-point theory, what happens to the body's metabolic rate and fat storage efficiency after weight loss?
The set-point theory hypothesizes that calorie reduction depresses metabolic rate via reduced thyroid hormone production. It also suggests that weight loss may make the body more efficient at storing kilocalories as fat.
Card 56
A) Offer a quick fix. B) Emphasize long-term behavioral change. C) Limit food selections. D) Rely on testimonials.
B) Emphasize long-term behavioral change. Fad diets typically do not emphasize long-term behavioral change; instead, they often offer quick fixes and rely on gimmicks.
Card 57
How does consumption of fructose contribute to nonalcoholic fatty liver disease?
Consumption of fructose stimulates fat synthesis in the liver. This increased fat synthesis can lead to the accumulation of fat in the liver, contributing to nonalcoholic fatty liver disease.
Card 58
Define 'appetite' and how it differs from physiological hunger.
Appetite is the desire to eat appealing food, often influenced by external cues like advertising or the sight/smell of food. It differs from physiological hunger, which is the body's innate need for energy.
Card 59
What is Prader-Willi syndrome and how does it affect an individual's eating behavior?
Prader-Willi syndrome is a rare genetic condition that causes people to have insatiable appetites. This leads to chronic hunger and a constant desire to eat, making weight management extremely challenging.
Card 60
Why might low-carbohydrate diets lead to rapid initial weight loss, even if not sustained long-term?
Low-carbohydrate diets often lead to rapid initial weight loss primarily due to the loss of body water. This occurs as glycogen stores are depleted (glycogen binds 3g water per 1g) and amino acids from muscle tissue (also high in water) are used for energy.
Card 61
What significant health concern led the FDA to ban most supplements containing ephedra in 2004?
The FDA banned most supplements containing ephedra in 2004 due to serious side effects, including death. This highlights the potential dangers of unregulated weight-loss supplements.
Card 62
What is the primary difference between 'eating disorders' and 'disordered eating'?
Eating disorders are psychological disturbances leading to physiological changes and serious health complications, becoming routine. Disordered eating refers to chaotic and abnormal food-related practices that are temporary and often occur with stress, like skipping meals.
Card 63
Why is it important for patients who undergo bariatric surgery to take vitamin and mineral supplements?
Bariatric surgery can lead to nutrient deficiencies and bone loss due to changes in digestion and absorption. Taking vitamin and mineral supplements helps to mitigate these risks and support overall health post-surgery.
Card 64
A) Ghrelin B) Peptide YY C) Leptin D) Cholecystokinin (CCK)
C) Leptin. Leptin is secreted by adipose tissue and functions to reduce hunger and inhibit fat storage.
Card 65
How does the typical Western diet contribute to intestinal dysbiosis?
The typical Western diet, characterized by low fiber and high amounts of fat, animal protein, and added sugars, creates an environment that fosters an unhealthy imbalance of gut microbiota, leading to dysbiosis.
Card 66
What are the three major short-chain fatty acids (SCFAs) that result from the fermentation of undigested carbohydrates by gut microbiota?
The three major SCFAs resulting from this fermentation are butyrate, propionate, and acetate. These play crucial roles in providing energy for colon cells and other metabolic processes.
Card 67
Explain how high-fat foods can lead to excess calorie intake.
High-fat foods are energy-dense, meaning they contain a large number of calories in a small volume. This energy density makes it easier to consume a high amount of calories before feeling full, leading to excess calorie intake.
Card 68
What is one criticism of the set-point theory regarding body weight?
Critics argue that body weight does not remain constant over time and that changes may be due more to lifestyle and environmental factors than strict biological controls like a set point. This suggests weight is more adaptable than the theory implies.
Card 69
A) Metabolic rate B) Hormone production C) Body frame size D) Food advertising preferences
D) Food advertising preferences. Metabolic rate, hormone production, and body frame size are listed as inherited factors, while food advertising preferences are an environmental influence.
Card 70
How do intragastric balloons assist in weight loss?
Intragastric balloons are FDA-approved devices that are placed in the stomach. They take up space, which helps individuals feel full sooner and consume less food, thereby aiding in weight loss.
Card 71
What is a potential consequence of intestinal dysbiosis on overall health?
Intestinal dysbiosis may cause chronic systemic inflammation and impaired energy metabolism. This can lead to serious health conditions such as type 2 diabetes and obesity.
Card 72
Why are low-fat approaches to dieting often difficult to follow for the long term?
Very-low-fat approaches, such as the Pritikin Diet, are often difficult to follow long-term due to low palatability (they are not tasty) and the elimination of many favorite foods, leading to monotony and lack of adherence.
Card 73
What is the recommended approach for individuals who are underweight and wish to gain weight healthily?
For healthy weight gain, individuals should gradually increase consumption of calorie-dense foods, especially those high in healthy fats, replace beverages with nutritious calorie sources, maintain a regular meal and snack schedule, and add muscle mass through resistance training combined with increased calorie intake.
Card 74
Define 'disordered eating' and explain how it differs from a clinically diagnosed 'eating disorder'.
Disordered eating refers to chaotic and abnormal food-related practices that are temporary in nature and often occur with stress, such as skipping meals or following fad diets. Eating disorders, on the other hand, are psychological disturbances that lead to physiological changes and serious health complications, becoming routine rather than temporary.
Card 75
What is the primary characteristic that distinguishes Binge-Eating Disorder (BED) from Bulimia Nervosa (BN)?
The primary distinction is the absence of compensatory purging behaviors in Binge-Eating Disorder. While both involve episodic bingeing, individuals with Bulimia Nervosa engage in purging behaviors like vomiting or excessive exercise after a binge, which is not characteristic of BED.
Card 76
Why did the FDA ban most supplements containing ephedra for weight loss in 2004?
The FDA banned most supplements containing ephedra due to serious side effects, including death. This action was taken because these supplements were found to be unsafe and ineffective, highlighting the risks associated with untested weight-loss products.
Card 77
Which of the following is NOT typically considered a suspicious claim for a weight-loss product according to the Federal Trade Commission?
D. Recommends a balanced diet and regular exercise for gradual weight loss. Claims that suggest quick, effortless, or extreme weight loss without lifestyle changes, or that rely heavily on 'before' and 'after' photos, are generally considered suspicious and potentially misleading.
Card 78
What is 'Anorexia Nervosa' and what is a key psychological characteristic associated with it?
Anorexia Nervosa is a severe psychological disturbance characterized by self-imposed starvation that results in malnutrition and low body weight (BMI < 18.5). A key psychological characteristic is a distorted body image, where individuals perceive themselves as overweight despite being emaciated.
Card 79
How do very-low-fat approaches to dieting, such as the Pritikin Diet, typically impact total caloric intake from fat?
Very-low-fat approaches typically supply only 5-10% of total kilocalories from fat. While not harmful to healthy adults, this severe restriction can make these diets difficult to follow long-term due to low palatability and the elimination of many favorite foods.
Card 80
Explain 'Muscle Dysmorphia' and identify the demographic it primarily affects.
Muscle dysmorphia is an unhealthy preoccupation with the body being too small or not muscular enough. It almost exclusively affects men, particularly bodybuilders, who often use anabolic steroids and are obsessed with exercise, carrying a high risk of suicide.
Card 81
A person has a BMI of 17.8. What is their weight status, and what could be potential causes for this status?
A BMI of 17.8 indicates that the person is underweight. Potential causes include genetics (high metabolic rate, tall body frame), excessive physical activity, or certain chronic diseases like cancer, tuberculosis, AIDS, inflammatory bowel disease, or depression.
Card 82
What is 'Diabulimia' and what serious health complications can arise from it?
Diabulimia is a dangerous practice where people with type 1 diabetes skip or use a lower insulin dose for weight control. This can lead to severe complications such as blindness, kidney failure, hypertension, heart attack, permanent heart damage, stroke, and nerve damage.
Card 83
What is the 'Female Athlete Triad' and what are its three main characteristics?
The Female Athlete Triad is a risk for young women participating in appearance-based competitive sports that require low body mass. Its three characteristics are low energy availability, reproductive system disturbances (like menstrual irregularities due to low estrogen), and reduced bone mineral density.
Card 84
Which of the following is a common consequence of purging behaviors in Bulimia Nervosa?
C. Blood chemistry abnormalities. Purging behaviors, such as self-induced vomiting or abuse of laxatives, can cause significant blood chemistry abnormalities that increase the risk of death, as well as esophageal tears or bleeding.
Card 85
What is 'Night Eating Syndrome (NES)' and how does it differ from Binge-Eating Disorder?
Night Eating Syndrome (NES) involves episodic food binges in the evening or overnight that are not followed by purging. It differs from Binge-Eating Disorder primarily in the timing of the binges, which are specifically nocturnal, and the lack of compensatory behaviors.
Card 86
According to the source, what is the highest mortality rate of any psychological disorder?
Anorexia Nervosa has the highest mortality rate of any psychological disorder, with as many as 6% of cases resulting in death from causes such as suicide, heart failure, or alcoholism.
Card 87
When treating an eating disorder, why is a multidisciplinary group of experts considered necessary?
A multidisciplinary group of experts in nutrition, mental health, and medicine is necessary for optimal treatment because eating disorders involve complex nutritional, medical, and psychological components that require integrated care to stabilize healthy eating patterns, improve nutritional status, and address underlying psychological issues.
Card 88
How does Cognitive Behavioral Therapy (CBT) primarily help in treating Bulimia Nervosa and Binge-Eating Disorder?
Cognitive Behavioral Therapy (CBT) is a major treatment approach for BN and BED because it is a psychological therapy that helps address unhealthy emotions and behaviors. It teaches coping strategies to use when under stress, which can help individuals manage triggers for bingeing and purging.
Card 89
What is the general medical term for 'loss of appetite'?
The general medical term for loss of appetite is 'anorexia'. This term is distinct from 'Anorexia Nervosa', which is a specific psychological disturbance.
Card 90
What percentage of total kcal from fat do very-low-fat approaches like the Pritikin Diet typically supply?
Very-low-fat approaches typically supply 5-10% of total kcal from fat. This extreme restriction is often cited as a reason for the difficulty in long-term adherence to these diets.
Card 91
What is the estimated occurrence of Anorexia Nervosa among American females?
Anorexia Nervosa is estimated to occur in 0.5% of American females. This figure highlights its prevalence as a serious psychological disturbance.
Card 92
Which of the following describes a characteristic of Bulimia Nervosa?
B. Lack of control over eating during food binge. Individuals with Bulimia Nervosa consume large volumes of food in a short period and feel a lack of control, followed by compensatory purging behaviors. Their BMI is often in the normal or overweight range.
Card 93
What is the most common eating disorder in the United States, and what percentage of adult Americans does it affect?
Binge-eating disorder (BED) is the most common eating disorder in the United States, affecting 2-3.5% of adult Americans. It is characterized by episodic bingeing not accompanied by purging.
Card 94
What are two key lifestyle practices recommended for individuals who are underweight and trying to gain weight?
Two key lifestyle practices recommended for gaining weight include gradually increasing the consumption of calorie-dense foods, especially those high in healthy fats, and adding muscle mass through resistance training combined with increased calorie intake. Reducing excessive physical activity is also advised.
Card 95
What is the main difference in hormonal impact between the Female Athlete Triad and the Male Athlete Triad?
The main difference lies in the specific hormones affected. In the Female Athlete Triad, severe food restriction leads to low estrogen levels, contributing to menstrual irregularities. In the Male Athlete Triad, severe food restriction leads to low levels of testosterone.
Card 96
What is one of the primary reasons low-carbohydrate dieters often experience higher HDL and lower triglycerides?
Low-carbohydrate dieters often experience higher HDL (good cholesterol) and lower triglycerides due to the dietary shift. This change typically involves reducing refined carbohydrates and often increasing intake of healthy fats and protein, which can positively impact lipid profiles.
Card 97
What is a major challenge for individuals trying to follow very-low-fat approaches to dieting for the long term?
A major challenge for long-term adherence to very-low-fat diets is their low palatability and the elimination of favorite foods. This makes it difficult for individuals to sustain the diet over extended periods, despite it not being harmful to healthy adults.
Card 98
What percentage of American females are estimated to be affected by Bulimia Nervosa?
Bulimia Nervosa is estimated to affect 2-3% of American females. It is more common among women than men and is characterized by cycles of bingeing and purging.
