If you’re in the market for a continuous glucose monitor, or CGM, you may be unsure of how to go about getting your hands on one. There are a variety of different programs out there, and each has its own features and uses.
As a first time buyer, it may be challenging and overwhelming to figure out what type of glucose monitoring program is right for you and your wellbeing. But, if you’re ready to explore your blood glucose levels and excited to learn how to build healthier lifestyle habits, you’ve come to the right place.
In this article, we’ll break down the benefits and drawbacks to some of the top CGM programs on the market, and share tips to help you determine which program is the right option for you.
What is a CGM and Who Can Use it?
A continuous glucose monitor is a device that measures your glucose levels in real time as you eat, sleep, and go about your day. This sensor is placed on the back of your arm, and measures interstitial glucose through a small fiber that is painlessly inserted under your skin.
With a CGM, you’re able to see how your blood glucose spikes and dips throughout the day, which makes it unique compared to other methods of measuring glucose levels such as a finger prick. The insights provided by a CGM can be used to support behavioral changes for any type of wellness goal.
Like many inventions, the use of CGMs has evolved over the years. Nowadays, anyone who wants to observe their glucose levels in response to different foods, activity, and even stress can do so through a CGM provider such as Nutrisense, Levels, Signos, January, or Veri.
When getting started, having expert guidance from a credentialed dietitian or nutritionist can help you navigate your data and identify trends so that you can make the most of your program, especially if you opt for a shorter plan. Whether you're looking for the best CGM for weight loss, improving fitness, or any other goal, continuous glucose monitors can provide useful insights to support long-term change.
If you’re looking to build sustainable habits down the road, you may want to choose a longer term plan. A six or 12 month program can help you understand your glucose, identify trends, and form lasting habits over time.
Many of the CGM programs we’ll detail below offer discounted rates for longer commitments. So, take your time to mull it over and decide what your health goals are and what you’re looking to get out of a CGM program.

- You’ll need to consent to being part of ZOE’s clinical study and meet certain criteria in order to gain access to CGMs.
- ZOE’s health coaches only need to have received a Bachelor’s degree in nutrition science, rather than the rigorous qualifications required of Nutrisense nutritionists.

But don’t take it from us! Here’s what one of our members, Jennifer Brumit had to say about our program:
“I sort of knew what it all meant, and I think the Nutrisense app is fantastic. But if it were not for my dietitian, Patrick, I wouldn't have been able to really understand. I think you can look at the app and see things and think, 'Here's this number.' But [my dietitian] has been so great behind the scenes to say, "Hey, look at these numbers," and "This is what it all really means." So now, understanding all that, it’s almost like reading the fine print. It’s been so much easier being able to reach out and communicate with him, and it helped me learn so many things.”
