Keep your waist less than half your height!

Standard weight scales and BMI tables have limitations. This co-authored study of 2,153 active adults evaluates how waist-to-height ratio serves as a practical indicator of fitness and wellness.

Key Takeaways:

  • Health Baseline: Keeping your waist under half your height is a well-established guideline to help manage cardiometabolic risk.

  • The 0.50 Threshold: Physical performance in load-bearing and aerobic tasks shows a progressive decline as this ratio crosses the 0.48–0.50 range.

  • Accessible Screening: Provides a simple, reliable metric to flag health and performance drops more effectively than body weight alone.
