Understanding your BMI
Body Mass Index (BMI) is a simple screening measure that relates your weight to your height. It's widely used because it's fast and free to calculate, but it doesn't distinguish between muscle and fat — so an athlete and someone with a higher body-fat percentage could show the same BMI. Use it as a starting point, not a diagnosis, and pair it with how you feel, your energy levels, and other measurements over time.

Underweight — consider speaking with a healthcare provider about a healthy gain plan.
18.5–24.9
Healthy weight range for most adults.
25 and above
Overweight or obesity range — small, sustainable changes tend to work best.
