BMI categories explained (and what BMI misses)

BMI, or Body Mass Index, is a simple calculation using your height and weight to estimate body fat. It’s widely used in healthcare settings for quick health assessments. However, BMI has limitations and doesn’t account for muscle mass, bone density, gender differences, or age.

How the estimate works

BMI categories include underweight (below 18.5), normal weight (18.5-24.9), overweight (25-29.9), and obesity (30 and above). These classifications are based on statistical averages but may not accurately reflect individual health conditions. For example, athletes with high muscle mass might fall into the 'overweight' category despite being healthy. Additionally, BMI doesn’t measure body fat distribution or visceral fat levels, which can be crucial for assessing cardiovascular risk.
