What range of Body Mass Index (BMI) is considered a healthy weight?

The range of Body Mass Index (BMI) considered a healthy weight is 18.5 to 24.9. This classification is widely accepted by health organizations, including the World Health Organization. A BMI within this range is associated with a lower risk of developing weight-related health issues, such as type 2 diabetes, heart disease, and certain cancers, while also indicating an ideal balance of body fat and lean mass.

Values under 18.5 are categorized as underweight, which can lead to malnutrition and other health complications, while a BMI from 25.0 to 29.9 is classified as overweight and may suggest an increased risk of health problems associated with excess weight. A BMI of 30.0 and above is categorized as obese, which further elevates the risk for severe health conditions. Therefore, the range of 18.5 to 24.9 is the optimal zone for maintaining overall health.
