In fact, about 40% of adults and 20% of adolescents in America were obese as of 2017. The CDC report that this is the highest record ever. Health experts and numerous research have concluded that the major causes of obesity are unhealthy diet, lack of exercise, and lack of sufficient sleep. Since Americans seem to have a fondness for fast food, the numbers might just continue to increase. Obesity can be a thing of the past. If only more people would make a habit of moving around doing chores, choosing the healthy food, and getting enough sleep. Until then, here are 15 of the most obese people in the world. Sadly, most of them are Americans.
