Continuous glucose monitors (CGMs) have become the latest wellness trend—even for people who don’t have diabetes.

But are they actually effective? Or just an expensive gadget with clever marketing? In this article, Dr. Barry Sears explains who truly benefits from CGMs, what the data says about their impact on weight loss and HbA1c levels, and why managing insulin—not just glucose—is the real key to better health. Before spending $100 a month on glucose patches, discover why the Zone Diet, paired with omega-3s and polyphenols, may offer a far more powerful, and cost-effective solution. |
