Final answer:
Approximately 69 percent of the U.S. adult population is considered overweight or obese according to the CDC.
Step-by-step explanation:
In the United States, according to the U.S. Centers for Disease Control and Prevention (CDC), nearly 36 percent of adults over 20 years old were obese and an additional 33 percent were overweight, leaving only about 30 percent of the population at a healthy weight. This means that approximately 69 percent of the U.S. adult population is considered overweight or obese. Obesity is determined by the body mass index (BMI), and a BMI of 30 or higher is considered obese. A BMI of 25 to 29.9 is considered overweight.
