43 | The Problematic Origins of BMI: Why This Health Metric Is Failing Us

Is BMI really an accurate measure of health, or is it an outdated tool rooted in inequality that is causing more harm than good?

In this episode 43 “The Problematic Origins of BMI: Why This Health Metric Is Failing Us” of the How to Fitness Podcast, we take a deep dive into the origins of the Body Mass Index (BMI), uncovering its surprising (and upsetting) history and the flawed way it’s used today. BMI was never meant to be a measure of individual health, yet it continues to impact medical care, insurance coverage, and even personal perceptions of health and self-worth.

BMI isn’t the full story when it comes to health. Tune in as we break down why it’s time to rethink how we define health and move toward more accurate, inclusive measures.
