Final answer:
Approximately a. 69% of American adults are overweight or obese with nearly 36% classified as obese and 33% classified as overweight.
Step-by-step explanation:
According to the information provided, the percentage of American adults who are overweight is significant. When considering individuals classified as overweight (BMI between 25 and 29.9) and those classified as obese (BMI of 30 or higher), the U.S. Centers for Disease Control and Prevention (CDC) reported that nearly 36 percent of adults over 20 years old were obese and an additional 33 percent were overweight as of 2010. This indicates that approximately 69% of American adults are either overweight or obese, with 36% in the obese category and 33% in the overweight one.
The high level of obesity and overweight status has contributed to various health challenges within the United States. Factors contributing to this include high-calorie diets, sedentary lifestyles, and socio-economic dynamics that may limit access to healthy food options and opportunities for physical activity.
Furthermore, the probability of a person consuming a diet high in fat (over 40 percent of their calories from fat) stands at about 0.3446, with nearly 25 percent of the population consuming less than 29.26 percent of their calories as fat. These dietary trends contribute to the overall weight issues.
Given that more than two-thirds of the adult population is struggling with weight, efforts at weight management, including reduced food consumption and increased exercise, are frequently reported, with 42 percent of adults recently attempting to lose weight.
Therefore, in response to the student's question, the correct answer is option a. 69%.
