Some main causes of obesity in America include a sedentary lifestyle, unhealthy diet and the environment in which people live. Most Americans indulge in large meals high in unhealthy fats, sugary drinks, refined grains and red meat, which is a perfect recipe for obesity, says the Harvard T.H. Chan School of Public Health. Studies indicate children develop obesity because they eat more, without being cognizant of the large portions they consume, state the Centers for Disease Control and Prevention.
When people are inactive, they tend to use less calories than they take in, leading to obesity, according to the National Heart, Lung, and Blood Institute. Many Americans are physically inactive because they spend more time watching televisions or enjoying other technological conveniences, while fewer physical work demands lessen the need to burn more calories. Reports indicates that individuals who spend more than two hours watching TV are at risk of obesity.
Americans live in an environment that tends to support unhealthy lifestyle habits. Bombarded by food advertisements for high-fat snacks and unhealthy food options that are readily available, Americans purchase high-calorie foods to the detriment of their health, remarks the NHLBI. Hectic work schedules, the prohibitive cost of healthier food options for some people, and inadequate amenities for recreation or exercise increase the risk of obesity.
