In America, what percentage of adults are overweight or obese?

Question

BlackTom AI · Accepted Answer

Body mass index (BMI) classifications show that the combined share of adults who are either overweight (BMI 25.0–29.9) or obese (BMI ≥30.0) is roughly 70% in the United States.

1. Relevant knowledge points and concepts
- BMI is the standard epidemiological measure used to classify weight status in adults: underweight, normal weight, overweight, and obese.
- Public health surveys (e.g., CDC national health data) report prevalence by these BMI categories; the sum of the overweight and obese categories gives the percentage of adults who are above a healthy weight range.

2. Step-by-step reasoning
- Find the usual prevalence values from national data: the overweight-only group (BMI 25.0–29.9) is commonly reported near ~30–32% of adults, while the obese group (BMI ≥30.0) is commonly reported near ~38–40%.
- Add the two categories because the question asks for the percentage who are overweight OR obese (inclusive OR).

3. Calculation (intermediate steps shown)
- Overweight (approx): 31%
- Obese (approx): 39%
- Total overweight or obese = 31% + 39% = 70%

4. Why the correct answer is correct
- The sum of the overweight and obese prevalence yields approximately 70%, matching option d. This reflects the broadly reported statistic that about seven in ten American adults fall into one of these two categories.

5. Why the other choices are incorrect
- a. 30% is far too low (this is closer to the obese-only or overweight-only subgroup, not the combined total).
- b. 50% underestimates the combined prevalence by a substantial margin.
- c. 85% is too high compared with national survey data and would imply almost all adults are above healthy weight, which is not supported by the data.

6. Conclusion
- Therefore, the correct choice is d. 70%, which matches the provided answer.
