Is BMI Accurate? Better Ways to Measure Health & Body Composition

Is Body Mass Index actually a reliable measure of health?

In this episode, Amanda Jones breaks down the history of BMI, why it was never designed to assess individual health, and how it can misclassify muscle, bone density, and body composition.

You’ll learn:

• Where BMI came from and how it became standard in medicine
• Why BMI does not distinguish fat from muscle
• How height, sex, and ethnicity influence BMI interpretation
• Why some athletes and metabolically healthy individuals fall into “overweight” categories
• The role of clinician bias in weight-based assumptions
• Better tools for assessing health, including waist-to-height ratio, body fat percentage, fasting insulin, triglycerides, and HDL

Health cannot be reduced to a single number.

This episode offers a more nuanced, evidence-based way to evaluate weight, metabolic health, and overall wellness — without shame or oversimplification.

If you’ve ever been told your BMI defines your health, this conversation will help you understand what matters more.
