A Biometric Story
Often called: WtHR, The Golden Ratio

Waist-to-Height Ratio (WtHR)

A powerful measure of how your body store energy around your center.

The Science of You

The waist-to-height ratio is one of the most honest markers of your metabolic health. It simply looks at your waist size compared to your height. Keeping your waist less than half of your height is one of the best 'secrets' to a long, energetic life.

Why it Matters for You

This ratio is often more accurate than BMI because it focuses on visceral fat—the fat stored near your organs. Improving this number is one of the most impactful things you can do for your heart.
