What is a continuous glucose monitor (CGM)?

Learn how these devices work and how you can use them to optimize your metabolic health and wellness.

Continuous Glucose Monitors (CGMs) are small, wearable sensors used to measure your blood sugar throughout the day. They offer real-time insights into how your body reacts to different meals and activities such as sleep and exercise.

And when paired with an app like Veri—which translates CGM readings into trends and scores—a CGM can help you optimize your diet and lifestyle based on your body’s unique needs.

What do people use CGMs for?

CGMs can be used by anyone— not just for those with diabetes or other blood sugar concerns. We could all benefit from knowing more about how our bodies work and how to best fuel them. That said, here are some of the reasons people use CGMs (as these concerns are often linked to metabolic health):

  • weight loss
  • inflammation
  • discovering the right foods for your body
  • acne/skin concerns
  • sexual health
  • longevity
  • athletic performance

By far, the most common reason people use CGMs is when they’re not seeing results related to weight management or fitness goals. CGMs help you see exactly which foods trigger insulin and fat storage in *your* body, which helps you tailor your diet with precision. With Veri, you'll learn the foods, habits, and glucose hacks that will help you hit your health goals, while still getting to enjoy your life.

Our CGM: Abbott’s FreeStyle Libre glucose sensor

We useAbbott’s FreeStyle Libre glucose sensor, which is around the size of a double-stacked quarter. It sits on the back of your upper arm and pairs with your phone through NFC technology. So whenever you want to check your glucose, all you have to do is scan the sensor with your phone.

The sensor automatically measures your glucose every minute and stores eight hours of information. You can wear it for up to 14 days. And you don’t have to change your lifestyle to wear a CGM: Showering, exercising, and even swimming up to one meter deep are fine.

Does it hurt to install or wear it?

Nope! The Freestyle Libre detects your glucose with a rubbery filament—not a needle!* The thickness of the filament is less than 0.4 mm (same as about 10 human hairs), and it only sits about 5mm under the skin of the arm, so most people feel no discomfort at all. And after the 14-day sensor cycle is over, you just peel it off like a bandage.

*FYI: the sensor applicator uses a needle only to place the filament in your arm. But you can’t even feel it. 

How long do you have to wear a CGM for the best results?

Generally, you’ll get the most benefit from wearing a CGM for at least 3 consecutive months (why we offer a 3-month commitment plan). This is enough time to help you gain the deepest understanding of your metabolic health, including:

  • which foods spike your glucose,
  • which foods create stability,
  • and how much sleep/exercise you need for balanced glucose.

Here's how Veri works and what to expect from your first three months and beyond. We find that many people use a CGM indefinitely because it helps them monitor their progress, stick to their goals, and continue to see amazing results.

In conclusion

Continuous glucose monitors are a safe, pain-free technology that you can use to reverse the effects of processed foods and crash dieting.
