Body Mass Index (BMI) is a simple calculation that uses your height and weight to estimate You can in a healthy weight range. While it's widely used, it's important to understand what the number actually tells you.

BMI Categories

  • Underweight (below 18.5): May indicate that you're not getting enough nutrition. Consider consulting a healthcare provider.
  • Normal (18.5 - 24.9): Generally associated with the lowest risk of weight-related health issues.
  • Overweight (25 - 29.9): May be a signal to monitor your diet and activity levels.
  • Obese (30 and above): Associated with increased risk for conditions like diabetes and heart disease.

What BMI Doesn't Tell You

BMI is a useful screening tool, but it has limitations. It doesn't distinguish between muscle and fat, so athletes with high muscle mass may show as "overweight" despite being very fit. It also doesn't account for factors like age, gender, or body fat distribution. Use BMI as one data point, not a final verdict on your health.
