What body mass index (BMI) value is generally used to define obesity?
BMI 25 - 29.9
BMI < 18.5
BMI ≥ 30
BMI 18.5 - 24.9
A BMI of 30 or higher is the standard threshold for classifying an adult as obese. Lower BMI ranges correspond to overweight, normal weight, or underweight classifications.
Which lifestyle factor most directly contributes to weight gain?
Regular physical activity
High-calorie diet
Drinking water
Adequate sleep
Consuming more calories than the body uses - especially from high-calorie foods - directly leads to weight gain. Other factors like activity and sleep influence weight but are not as direct.
Obesity most strongly increases the risk of developing which chronic condition?
Migraine
Asthma
Type 2 diabetes
Migraine
Excess body fat contributes to insulin resistance, which is a direct pathway to type 2 diabetes. While obesity can influence other conditions, diabetes risk is most prominent.
Genetic factors contribute to obesity by influencing:
Calorie intake exclusively
Skin elasticity
Metabolic rate and appetite regulation
Hair growth
Genes can affect how quickly the body burns energy and how hunger and fullness signals are regulated. They do not directly determine unrelated traits like skin elasticity or hair growth.
A primary prevention strategy for obesity at the individual level is:
Dietary counseling and exercise promotion
Weight-loss surgery
Medication for weight loss
Hospitalization
Primary prevention focuses on avoiding disease onset through lifestyle modifications like healthy eating and regular physical activity. Surgery and medication are treatment, not primary prevention.
Excess consumption of sugar-sweetened beverages primarily leads to weight gain through:
Increased protein synthesis
Excess liquid calorie consumption
Dehydration
High fiber content
Sugar-sweetened beverages add liquid calories that are less filling than solid foods, leading to a caloric surplus and weight gain. Fiber and protein are not predominant in these drinks.
Basal metabolic rate (BMR) is best described as the:
Total daily energy expenditure
Calories burned during exercise
Energy used for digestion
Energy expenditure at rest
BMR refers to the minimal energy needed to maintain vital functions while at complete rest, not including activity or digestion. Total daily expenditure includes BMR plus all other activities.
Which environmental factor most often promotes obesity?
Strict food labeling laws
High bike lane density
Availability of safe parks
Abundant fast-food outlets
Easy access to calorie-dense fast food encourages unhealthy eating habits and weight gain. Safe parks and bike lanes support activity, while labeling can guide healthier choices.
Monogenic obesity is characterized by:
Multifactorial gene interactions
Entirely lifestyle-driven weight gain
Single gene mutations with strong effect
Cultural transmission only
Monogenic obesity is caused by mutations in a single gene that drastically affect weight. Most obesity cases are polygenic or influenced by environment and lifestyle.
Community-wide obesity prevention programs often include:
Genetic screening of all residents
Exclusive focus on athletic training
Policy changes to increase healthy food access
Individual medication prescriptions
Effective community strategies modify the environment - such as improving healthy food availability - rather than focusing solely on individual treatments or screenings.
Leptin is a hormone that primarily:
Increases fat storage directly
Promotes glucose absorption in muscles
Signals satiety and reduces appetite
Stimulates hunger
Leptin is secreted by fat cells and communicates to the brain that energy stores are sufficient, thereby reducing hunger. It does not directly increase fat storage or stimulate hunger.
Chronic sleep deprivation can contribute to obesity by:
Increasing insulin sensitivity
Enhancing mitochondrial efficiency
Decreasing ghrelin levels
Disrupting hunger and satiety hormones
Lack of sleep raises ghrelin (hunger hormone) and lowers leptin (satiety hormone), leading to increased appetite and calorie intake.
High glycemic index foods can lead to weight gain because they:
Do not affect blood sugar
Increase long-term satiety more than low GI foods
Trigger rapid blood sugar spikes and insulin release
Cause slow glucose absorption
Rapid blood sugar spikes prompt insulin surges that can lead to fat storage and subsequent hunger, promoting overeating.
Sedentary behavior contributes to obesity primarily through:
Elevated resting metabolic rate
Enhanced fat oxidation
Increased muscle mass
Reduced overall energy expenditure
Sitting or low-activity lifestyles lower daily calorie burn, making it easier to maintain a positive energy balance and gain weight.
Alterations in gut microbiota can influence obesity by:
Directly causing muscle hypertrophy
Modifying energy extraction from food
Improving skin hydration
Increasing nutrient malabsorption
Certain gut bacteria increase caloric extraction from nutrients, which can contribute to a higher net energy intake and weight gain.
Evaluating a sugar-sweetened beverage tax, which outcome likely indicates success in obesity prevention?
No change in beverage prices
Rise in total caloric intake from other sources
Increased beverage industry profits
Decreased consumption of taxed beverages
A decline in consumption of taxed sugar-sweetened beverages demonstrates that the fiscal policy reduced calorie intake, a key goal for obesity prevention.
The FTO gene is associated with obesity risk primarily because it influences:
Appetite regulation and energy intake
Muscle fiber composition
Lipid absorption in the intestine
Thermogenesis in brown fat
Variants in the FTO gene are linked to increased appetite and higher caloric intake, which elevates the risk of developing obesity.
Which of the following is NOT a component of metabolic syndrome?
Abdominal obesity
Insulin resistance
Elevated blood pressure
High HDL cholesterol
Metabolic syndrome includes low HDL cholesterol, not high. Elevated blood pressure, insulin resistance, and abdominal obesity are all diagnostic criteria.
Long-term studies comparing bariatric surgery to lifestyle interventions show that surgery generally results in:
No changes in obesity rates
Worse metabolic health
More significant and sustained weight loss
Identical outcomes to lifestyle changes
Evidence indicates that bariatric surgery produces greater and longer-lasting weight reduction and metabolic improvements than lifestyle interventions alone.
Epigenetic modifications from maternal obesity may predispose offspring to obesity by:
Causing mutations in metabolic genes
Altering gene expression without changing DNA sequence
Ensuring higher birth weight only
Changing the DNA sequence
Epigenetic changes - such as DNA methylation - modify how genes are expressed without altering the underlying sequence, affecting metabolic regulation in offspring.

Learning Outcomes

  1. Identify key factors contributing to obesity prevalence
  2. Evaluate the impact of lifestyle choices on weight gain
  3. Analyze genetic and metabolic influences on obesity
  4. Apply effective prevention strategies in real-world contexts
  5. Demonstrate understanding of obesity-related health risks

Cheat Sheet

  1. Understand the Role of Diet in Obesity - Think of your plate as a fuel tank: filling up on high-calorie, energy-dense foods can push you into the red zone. Fast-food portions have ballooned 2 to 5 times since the 1980s, sneaking extra calories into your daily total. Diet and Obesity
  2. Recognize the Impact of Physical Activity - Movement is your body's built-in calorie burner, so dancing, jogging, or even a brisk walk can help keep the energy balance in check. Experts recommend at least 150 minutes of moderate-intensity exercise each week to stay ahead of weight gain. Obesity
  3. Explore Genetic Influences on Obesity - Your genes can write part of the script for your body mass story; some variations, like those in the FTO gene, are linked to a higher BMI. Knowing your genetic predispositions helps you create a personalized plan to outsmart your DNA. Genetics of Obesity
  4. Examine Environmental Factors - It's not just food and exercise - certain chemicals called obesogens, such as BPA and phthalates, can mess with your hormones and encourage fat storage. Recognizing these hidden culprits empowers you to choose safer products and reduce exposure. Obesity and the Environment
  5. Assess the Influence of Socioeconomic Status - Your wallet and education level can play a major role in obesity risk, as limited access to health information and fresh foods makes healthy choices tougher. Understanding these social determinants highlights why community support and policy changes matter. Social Determinants of Obesity
  6. Identify Health Risks Associated with Obesity - Packing on excess weight isn't just about the mirror - it raises the risk of type 2 diabetes, heart disease, and even certain cancers. Spotting these risks early motivates you to adopt healthier habits for a longer, happier life. Obesity and Cancer
  7. Learn Effective Prevention Strategies - Prevention is your secret weapon: combine a colorful diet of fruits, veggies, and whole grains with fun physical activities to keep pounds in check. Watching portions, cutting back on processed snacks, and staying consistent can make a world of difference. Diet and Obesity
  8. Understand the Role of Metabolism - Think of metabolism as your body's internal engine - age, muscle mass, and hormones all influence how fast it burns fuel. Maximizing lean muscle through strength exercises and balanced nutrition helps rev up your calorie-burn rate. Obesity
  9. Recognize the Impact of Sleep on Weight - Skimping on shut-eye can throw your hunger hormones out of whack, making you crave extra snacks and pile on pounds. Aim for 7 - 9 hours of quality sleep each night to keep your appetite and energy in harmony. Obesity
  10. Explore Psychological Factors - Emotions like stress, boredom, and depression can turn us into accidental snack seekers, leading to overeating. Developing healthy coping strategies - like mindfulness, hobbies, or talking with friends - can help you manage emotional eating. Obesity
