What BMI classification corresponds to a BMI of 18.5 or lower?

A Body Mass Index (BMI) of 18.5 or lower falls under the classification of underweight. This classification indicates that an individual's weight is significantly below the healthy range for their height, potentially putting them at risk for various health issues. The BMI categorization is commonly used to assess body weight and help identify whether a person might be at risk due to being underweight, normal weight, overweight, or obese.

In general, underweight is recognized as a BMI below 18.5. This range is important as it allows healthcare professionals to identify individuals who may need dietary adjustments or other health interventions to reach a healthier weight. Maintaining a BMI above this threshold is often encouraged for overall health and wellbeing.

Normal weight is classified as a BMI from 18.5 to 24.9, while overweight refers to a BMI from 25 to 29.9, and obesity classifications begin at a BMI of 30 and above. Understanding these classifications is crucial for promoting health and guiding individuals in making informed decisions about their weight management.
