Final answer:
Approximately 69 percent of the US general population is either overweight or obese.
Step-by-step explanation:
According to the U.S. Centers for Disease Control and Prevention (CDC), as of 2010, nearly 36 percent of adults over the age of 20 in the United States were obese and an additional 33 percent were overweight. This means that the combined percentage of the general population that is either overweight or obese is approximately 69 percent.
