If you’ve been paying attention to the wellness and weight loss industries, then you might have heard the buzz around using a CGM for weight loss. A CGM, or continuous glucose monitor, is a small wearable device that syncs with an app on your phone and measures your glucose levels throughout the day.

Your blood glucose levels can give you a very insightful snapshot of your overall health in relation to food, exercise, stress, and sleep. Understanding your blood glucose and how these factors affect them can give you the keys to optimizing your nutrition, weight loss, and lifestyle.

I recently tried both Signos CGM and Nutrisense CGM, two very similar programs in concept, but with their own features and nuances. In this article, I am excited to share with you my experience of both as well as my recommendations for how to choose which CGM for weight loss is right for you.

Can a CGM Help You Lose Weight? How?

In order to answer this question, we have to first have an understanding of how insulin (glucose) controls our metabolism. Insulin is the driver of the car, so to speak, when it comes to our metabolism. It’s what’s referred to as an “anabolic” hormone, which means that it contributes to our bodies’ growth.

Here’s how it works:

  • Eating prompts our pancreas to release insulin into our bloodstream
  • Insulin then start directing our body with what to do, telling our body to burn glucose
  • It can shift our metabolism from burning fat to storing fat

For a healthy individual with a healthy metabolism who eats a nutrient-dense diet, their insulin releases likely work perfectly, metabolizing the sugar and storing minimal amounts of fat. However, those with abnormal metabolisms and poor diets will cause our bodies to release too much insulin, too often. This creates a situation where your body stores more insulin as body fat, making losing weight difficult.

This is where tracking and understanding your blood glucose levels become so valuable. By seeing the spikes in relation to your lifestyle choices in real-time, you’re able to make small, sustainable changes to your diet and lifestyle habits that will result in fewer insulin spikes, and ultimately, weight loss.

Understanding Your Blood Glucose Levels In Relation to Weight Loss

Every individual has a baseline glucose level and it’s the bedrock from where you will build your healthy diet. Both Signos and Nutrisense have tools in place to help you determine your baseline. With a baseline firmly established, you can then hone in on how the foods you eat are affecting your blood sugar. With this data, we can then maximize our metabolism and facilitate weight loss.

As a general rule, we don’t want to see our blood sugar spike more than 30 points after eating a meal, particularly, if our goal is to lose weight. With this in mind, we can monitor our baseline glucose levels and see how they respond post-meal. If you’re seeing huge spikes in your glucose, this is an indication that your eating habits are causing unhealthy spikes and that your diet could use some fine-tuning to ensure that your post-meal spike stays in a healthier range.

Next, let’s take a closer look at both Nutrisense and Signos and how these CGMs can help us to gather the data we need to understand our blood glucose levels as well as provide us with the tools we need to make them more manageable and conducive to weight loss.

Studies On CGMs and Weight Loss

Of course, we always like to back up any claims with some research and a study or two for proof. This study found that 87% of CGM users modified their food choices based on the data they collected from the glucose levels via their CGM. Furthermore, 47% of CGM users were more likely to go for a walk post-meal when they saw a rise in their blood sugar (walking or another physical activity can help moderate your levels). But, best of all, 90% of the study participants felt as though they were on a path to a healthier lifestyle thanks to the CGM.

Another study found that glucose spikes and dips can be controlled by your eating patterns i.e. eating again soon or eating more calories at a meal and throughout the rest of the day. Some people discover that they are snacking too much, never allowing their glucose to get back to baseline in between meals, leaving them with elevated levels throughout the day. With a CGM in place, you can use your glucose levels as a tool for something referred to as “appetite training” or the recognition of hunger signals.

Signos Overview

Signos takes an individualized approach to weight loss, understanding that we are all unique and so are the foods and habits that spike our individual glucose levels. With Signos, you can get real-time data collected from your CGM from every meal and snack that you eat.

The Signos team believes that healthy looks like:

  • The ability to see how your body responds to the food you eat.
  • Learning and understanding what spike your glucose (everyone is different!).
  • Use the information you receive to make small, sustainable changes that help you to avoid spikes and lose weight.

Signos partners with Dexcom CGM to provide you with some of the most up-to-date technology available in the space. Dexcom works seamlessly with the app, so there’s no need to scan or take any extra steps in order to get your updated glucose reading. Plus, you can set up alerts on your CGM to let you know when your glucose level is either spiking too high or too low, which can really come in handy and eliminate the need for you to be constantly checking the app.

Cons

Which Is Better For Weight Loss: Signos or Nutrisense?

To be honest, I find that both Nutrisense and Signos offer weight loss potential thanks to the app features and tracking capabilities. However, Signos is a little easier to use and understand than Nutrisense. However, Nutrisense offers complimentary access to an RD for the first month, which provides users with the opportunity to get clarity and gain an understanding of their data. But, keep in mind that once the free month is up, you will need to pay an additional $50 per month to maintain access to your RD.

Wrapping Up: Deciding Between Signos and Nutrisense Comes Down To…

Choosing a CGM for weight loss between Signos and Nutrisense comes down to what you value more: having limited access to a professional who will help you interpret the data or having access to an app that is easy to understand but also lets you access a professional should you need additional help. 

Using Signos, I found that the information I was given was much easier to understand and digest than Nutrisense. I was able to follow along with the prompts and tracking tools really easily and the numbers I was getting back made sense. With Nutrisense, on the other hand, I found the app to be a little more cumbersome to navigate and not as sharp. But, the fact that an RD reached out to me immediately after signing up was a huge bonus for me.

Overall, you really can’t go wrong with choosing either Signos or Nutrisense, both will provide you with the tools and strategies you need to make small lifestyle changes that will help you lose weight and live a healthier lifestyle.

Tips and Tricks From An Experienced CGM User

  • Be sure you read and watch the instructions for applying your CGM carefully so that it’s placed in the correct space.
  • Take a look at your calendar and make sure that you are ready to commit to the time needed to spend tracking and logging inside your app. For Signos, you need to be fasting for a couple of exercises, so make sure you start at a time conducive to doing so.
  • Follow all of the prompts and take the tests and experiments seriously. While it can feel inconvenient to workout, eat, and track at certain times throughout your day, it’s all done for a reason and your compliance will ensure that you get the best results possible.
