What if the key to weight loss, better energy, and vibrant, lasting health isn’t about following generic advice, but about understanding your body’s signals?

Learn how to use continuous glucose monitoring to work with your body—not against it—in this revolutionary guide from New York Times bestselling author Bill Tancer.

Your body is constantly sending you signals about what it needs, but until now, most of us have been guessing. Continuous glucose monitoring technology is changing that, providing unprecedented insight into metabolic health and empowering users to make truly personalized wellness decisions.

In The Glucose Edge, Bill Tancer, chief data scientist for the metabolic health system Signos, leverages the world’s first database combining glucose readings, food logs, weight, sleep and exercise data—over three billion glucose data points across ten thousand life-years of metabolic data—to shed light on our wildly diverse metabolic responses, and the eating, exercise, and lifestyle changes that really work.

Tancer combines cutting-edge research with straightforward guidelines that will help you use continuous glucose monitoring to:

Recognize the hidden patterns driving your cravings and energy crashes

Learn “appetite training” techniques that use glucose data as your body’s personal fuel gauge

Determine what foods work best for your metabolism—and how simple tweaks in portion, food pairings, and timing can make a big difference

Understand why and how exercise and movement, quality sleep, and stress management impact your metabolic fitness

Keeping your glucose more stable can lead to better energy, sharper focus, improved metabolic health, reduced risk of chronic conditions, and sustainable weight management. Whether you’re looking to lose weight, enhance your athletic performance, support healthy aging, or simply feel your best every day, The Glucose Edge is an indispensable partner in using your CGM to make small, effective, science-backed adjustments that add up to meaningful results that last.
