BMI may be the most common way to measure obesity, but it’s far from the most accurate. In fact, your percentage of body fat is a much better predictor of cardiovascular risk and long-term health. The challenge? Most accurate methods—like underwater weighing or DEXA scans—aren’t exactly practical at home. In this Ask Dr. Sears post, I explain why body fat percentage matters more than BMI—and how you can measure it yourself using my Body Fat Calculator at ZoneLiving.com. You’ll also learn how the Zone diet and ZoneRx Foods can help you reduce excess fat, build lean muscle, and activate AMPK—the key to improving your metabolism. |
