In the context of dietary assessment, what BMI range is considered healthy for adults?

The range of 18.5 to 24.9 kg/m² is recognized as the healthy BMI range for adults. This classification is based on the relationship between body weight and height, offering an indication of body fatness and potential health risks associated with underweight and overweight conditions. A BMI within this range is generally associated with lower risks for chronic diseases such as type 2 diabetes, heart disease, and certain cancers, while also indicating that the individual has a healthy body composition.

Other ranges provided do not reflect the healthy weight category; for instance, a BMI of 17.5 to 22.9 kg/m² may indicate underweight status for some individuals, which can bring health risks associated with insufficient body fat and nutrient deficiencies. The range of 25 to 29.9 kg/m² is classified as overweight, and a BMI of 30 or above is considered obese, both of which are connected to higher prevalence of health issues. Thus, the selected range reflects optimal health markers for the adult population.
