Obesity is a problem in the United States. In fact, 42.5% of U.S. adults aged 20 and over have the disease. Not only is obesity the nation’s second leading cause of preventable death (behind only smoking cigarettes), it also leads to other serious health issues, including an increased risk of type 2 diabetes, high blood pressure, heart disease, stroke, cancer, sleep apnea and liver disease. The disease and its side effects impose a significant financial burden on America’s health care system.
