Is obesity the number one killer in the United States these days?
<|assistant|>
No, obesity is not the number one killer in the United States. The leading cause of death in the U.S. is coronary heart disease.  Heart disease is closely linked to lifestyle choices such as obesity and physical inactivity, making it the number one killer in the country. Other serious health conditions such as diabetes, cancer, and stroke also have links to obesity.
