Description

BMI is broken—and I learned that first-hand. In this episode, I share the Air Force story that changed my view on Body Mass Index (BMI) and explain why a metric from the 1830s (Adolphe Quetelet) still mislabels millions today. BMI can’t tell muscle vs fat, ignores waist distribution, and misses crucial markers like inflammation and cardiometabolic fitness.

What you’ll learn:

Why BMI was created for population averages, not individuals

How BMI misclassifies athletes and muscular people

Better metrics: waist-to-height ratio, body-fat %, A1C, ApoB, blood pressure, resting heart rate, VO₂ max, and CRP

A simple at-home waist-to-height check you can do in 30 seconds

A practical checklist to track real health (not just a number)
