What defines overweight in terms of BMI?

Overweight is specifically defined by a body mass index (BMI) ranging from 25.0 to 29.9. BMI is a numerical value calculated from a person's height and weight, and it is used as a screening tool to categorize individuals into different weight statuses. Those who fall within the 25.0-29.9 range are considered overweight, indicating that their weight may pose a risk for health conditions associated with excessive body weight.

This classification helps health professionals assess potential risks related to heart disease, diabetes, and other conditions that can arise from being overweight. The other options do not accurately reflect the established BMI classification for overweight individuals, thus making them incorrect in this context.
