<|assistant|>
Laziness is the number one cause of obesity in first world countries due to a variety of factors, such as easy access to fast and unhealthy food, increasing car dependence, longer work hours and workweeks, lack of time for physical activities, and a general decrease in overall physical activity. Additionally, it has been estimated that almost half of American adults are sedentary, indicating a further lack of overall physical movement and a corresponding decrease in caloric expenditure. All of these factors contribute to a decreased physical activity, and ultimately, to the rising prevalence of obesity across the first world.
