If a person has a genetic predisposition to obesity, accounting for 60% of their inherited risk, which factor would MOST effectively mitigate this predisposition?
If a person has a genetic predisposition to obesity, accounting for 60% of their inherited risk, which factor would MOST effectively mitigate this predisposition?
- Relying solely on medications that suppress appetite and increase metabolism.
- Consuming a diet rich in processed foods to counteract metabolic inefficiencies.
- Undergoing bariatric surgery to alter the body's physiological response to food intake.
- Engaging in regular physical activity and adopting mindful eating habits. (correct)
According to the set point theory, what physiological response is MOST likely to occur when an individual significantly reduces their caloric intake in an attempt to lose weight?
According to the set point theory, what physiological response is MOST likely to occur when an individual significantly reduces their caloric intake in an attempt to lose weight?
- An increase in leptin production, which further suppresses appetite.
- A permanent decrease in basal metabolic rate (BMR), leading to sustained weight loss.
- The body adjusting its metabolism to conserve energy, potentially hindering further weight loss. (correct)
- A rapid shift in the body's preferred fat distribution, resulting in targeted fat loss.
How does sleep deprivation MOST directly contribute to weight gain and obesity?
How does sleep deprivation MOST directly contribute to weight gain and obesity?
- By disrupting the balance of hunger-regulating hormones like leptin and ghrelin. (correct)
- By slowing down the basal metabolic rate (BMR), reducing the body's energy expenditure.
- By causing the body to preferentially store fat in the abdominal region.
- By increasing the production of thyroid hormones, accelerating fat storage.

Study Notes
- Obesity stems from both genetic predispositions and environmental factors.
Origins of Obesity
- Genetics contribute significantly, accounting for 40-70% of inherited traits that affect metabolism and fat distribution.
- The Set Point Theory suggests the body defends against weight changes by adapting metabolism.
- Metabolism is regulated by Basal Metabolic Rate (BMR) and Resting Metabolic Rate (RMR), which control energy expenditure.
- Hormones such as leptin and ghrelin have an impact on hunger and satiety.
- Environmental factors include limited access to healthy foods, the presence of food deserts, and the prevalence of high-calorie, processed foods.
- Lifestyle factors contributing to obesity are overeating, inactivity, lack of sleep, and psychological influences.
Health Risks of Obesity
- Obesity elevates the risk of several diseases like hypertension, diabetes, cardiovascular disease, cancer, and arthritis.
- Obesity also increases the likelihood of pregnancy and surgical complications, negative body image, and depression.
Weight Management Strategies
- Balanced diets with portion control is recommended, with avoiding fad diets.
- Physical interventions encompass exercise, drug therapies, and surgical options.
- Lifestyle adjustments involve problem-solving skills and redefining one's understanding of health.
Disordered Eating
- Common behaviors include preoccupation with food, unrealistic body perception, and emotional distress.
- Anorexia Nervosa is characterized by extreme food restriction and distorted body image, leading to a high mortality rate.
- Bulimia Nervosa involves binge eating followed by purging behaviors, and individuals are often at a normal weight.
- Compulsive Overeating includes binge eating without subsequent purging, driven by emotional factors.
Athletes & Eating Disorders
- Athletes in sports that emphasize thinness, such as gymnastics and figure skating, face an elevated risk of developing eating disorders.
- The Female Athlete Triad consists of an eating disorder, followed by amenorrhea, and then osteoporosis.
Body Image & Media Influence
- Unrealistic beauty standards promoted by media contribute to body dissatisfaction and disordered eating patterns.
- Store mannequins often exhibit proportions that deviate greatly from those of the average woman.
