Is obesity the number one killer in the United States these days?
<|assistant|>
No. While obesity is a health risk factor, it is not the number one killer in the United States. The number one killer in the United States is heart disease, which can be contributed to a variety of lifestyle factors, including obesity. Additionally, cancer is the second leading cause of death in the United States, followed by stroke, Alzheimer's disease, and kidney disease. All of these are illnesses that can be prevented or managed through healthy lifestyle choices.
