- Obesity in the U.S. has surged since the 1980s, with CDC data showing a significant rise among adults and children. The prevalence is higher in Hispanic and Black adults compared to whites. Factors contributing to obesity include behavior, environment, and food access, with poverty exacerbating risks in "food deserts." Globally, obesity affects 2 billion people, with policy interventions yet to reverse trends. Solutions focus on prevention and promoting healthy dietary patterns.
- 1.2: Energy Balance- Energy In, Energy Out–Yet Not As Simple As It Seems
- Energy balance, the relationship between energy intake and expenditure, is more intricate than simply balancing calories consumed and expended. Various factors influence this balance, some controllable and others not. Energy expenditure comprises basal metabolic rate (BMR), the thermic effect of food (TEF), and physical activity. BMR, largely determined by lean body mass, is influenced by factors like body composition, size, age, and nutrition.
- 1.3: Indicators of Health- BMI, Body Composition, and Metabolic Health
- Determining a healthy size involves a personalized assessment of overall health, considering factors beyond numbers on the scale, like family history and lifestyle. A healthy weight should be attainable without extreme dieting, compatible with good metabolic health, and acceptable to the individual. While Body Mass Index (BMI) is a simple tool for tracking weight relative to height, it has limitations and should not be solely relied upon for diagnosing health.
- 1.4: Overweight and Underweight- What Are the Risks?
- The page discusses the impact of energy balance on body weight, highlighting health risks associated with being overweight, obese, or underweight. Obesity is linked to chronic diseases like diabetes and heart issues, largely due to lifestyle and societal factors. Underweight individuals face nutritional deficiencies and chronic disease risks. Eating disorders such as anorexia, bulimia, and binge-eating are explored, noting psychological aspects and health complications.
