Study Notes
Obesity and Its Causes
- 7 million children and adolescents aged 2-19 years have obesity, with prevalence almost tripling since 1980
- Childhood obesity prevalence decreases with increasing education level of the household head
- Obesity prevalence in children is lower in highest income groups, highlighting health disparities
- The top-selling clothing size for women jumped from size 8 to size 14 in less than 20 years
- Changes in the food system, such as nutrition transition, ultra-processed foods, and technology shift, have driven obesity rates
- Portions have significantly grown over time, with adults consuming an average of 300 more calories per day than in 1985
- The USDA has introduced new requirements for serving sizes and nutrition labels, including the inclusion of added sugars and multiple serving settings
- Energy is measured in kilocalories (kcal) and not all foods are created equal in terms of energy density
- The energy density of foods is impacted by water, air, and fiber content, as well as macronutrient proportion
- Factors contributing to obesity include genetics, environmental and social elements, and behavior
- Regulation of energy balance involves short-term and long-term factors, such as ghrelin and leptin
- Genes that affect weight gain and increase "risk" for obesity are polygenic and influence behavior, food preference, and activity levels
