Final answer:
The correct answer to the question is that nearly 70% of Americans are overweight, and 30% are obese, which is consistent with CDC data and reflects serious public health concerns.
Step-by-step explanation:
According to one recent study, nearly 70% of Americans are overweight, and 30% are obese. This information aligns with data reported by the U.S. Centers for Disease Control and Prevention which indicated that by 2010, about 36% of adults over 20 years old were obese, and an additional 33% were overweight. Understanding these statistics is crucial as obesity is associated with various health issues, including diabetes, high blood pressure, and certain types of cancer.
