You've probably heard me rant about it before, but it’s worth emphasizing again: BMI is NOT the be-all and end-all statistic measuring our health. Widely adopted in medicine and by insurance companies, it's often used to justify various treatments and decisions. But the truth is, BMI measurements can be downright misleading, especially for those who have undergone significant weight loss.

In this episode, I'm going to illustrate just how flawed BMI can be, using a case study of two patients who have both shed a considerable amount of weight. Through these real-life examples and data, we’ll see why solely relying on BMI might not give you an accurate picture of your health. Instead, we'll explore how understanding body composition can provide invaluable insights that BMI alone cannot, empowering you to make better-informed decisions about your health journey.

If you have lost a significant amount of weight and are feeling confused or frustrated by your BMI, this episode is for you!

Oops! We need to make a small correction from this episode:

“We’re going to think about obesity as being over a body fat percentage of 31%.”
