Answer:
About one-third of the population is obese, the number is rising, and the study showed that obesity was contagious.
Explanation:
The most recent studies show that about 36% of the adult U.S. population is obese, and obesity has been rising in the recent decades.
Obesity is a serious disease that is comorbid with other chronic illnesses such as diabetes, cancer, and coronary artery disease.
The most common causes of obesity are poor diet, and a sedentary lifestyle. In the U.S., most people rely on their cars for their mobility and do not walk a lot, and many of them have diets high on added sugars and other carbohydrates, both things greatly contributing to weight-gain.
