As someone who puts a high priority on their health and seeks to understand the impact of various factors on my overall well-being, I was intrigued when I came across the Signos Continuous Glucose Monitor (CGM). This innovative device, once primarily used by individuals with diabetes, is now being marketed to a broader audience. With claims of empowering users to make informed decisions about their health, I decided to give it a try and share my experience in this review.
Understanding Signos: The Basics

Included in the Signos Kit are Alcohol Wipes, a Dexcom Sensor / Applicator, a Dexcom Transmitter and Signos Sports Covers.
The Signos CGM is a wearable device that continuously monitors blood glucose levels in real time. It consists of a small sensor with a tiny wire that is inserted just beneath the skin and a smartphone app that displays and interprets the data collected by the sensor. This technology, traditionally used by individuals with diabetes to manage their blood sugar levels, is now available to anyone interested in gaining insights into their metabolic health.
How Signos Works
Upon receiving the Signos device kit, I followed the instructions to apply the sensor to the back of my upper arm (can also be applied to the stomach). The process was straightforward and painless, and within a few hours, the sensor was calibrated and ready to provide real-time data. The accompanying smartphone app allowed me to easily track and interpret my blood glucose levels throughout the day.

The main purpose of the Signos CGM is to provide feedback on how specific foods and activities affect blood sugar levels. By monitoring the fluctuations in glucose levels, the device helps users understand how their body responds to different stimuli, such as meals, exercise, stress, and sleep. This information can then be used to make more informed decisions about diet and lifestyle choices.

Valuable Insights from Wearing Signos
Over the course of wearing the Signos CGM for a month, I gained valuable insights into my body’s response to various factors. Here are some key takeaways from my experience:
The Impact of Food Choices
One of the most eye-opening aspects of wearing Signos was seeing the immediate impact of my food choices on my blood sugar levels. I discovered that certain foods, even those traditionally considered healthy, could cause significant spikes in glucose levels. For example, I noticed that consuming a fruit smoothie on an empty stomach led to a similar blood sugar spike as indulging in a handful of Pull n’ Peel Twizzlers. This made me reevaluate my perception of “healthy” foods and consider the importance of balance and moderation in my diet.
Managing Blood Sugar Spikes
By closely monitoring my blood sugar levels, I learned strategies to manage and prevent spikes. Engaging in physical activity, such as going for a walk after a meal, helped to curb the rise in glucose levels. Additionally, combining sugary foods with fiber or non-processed carbohydrates proved effective in mitigating blood sugar spikes. For instance, consuming a sugary treat or a banana smoothie as part of a larger meal had a less pronounced impact on my glucose levels compared to having them as standalone snacks. These insights allowed me to make more informed choices about when and how to consume certain foods.

The Role of Sleep and Stress
I was fascinated to discover the connection between sleep, stress, and blood sugar levels. Monitoring my glucose levels during periods of poor sleep or increased stress revealed a direct correlation between these factors and my body’s response. When sleep-deprived or stressed, my blood sugar levels tended to be higher, highlighting the importance of prioritizing quality sleep and managing stress for optimal metabolic health.

Lots of valuable data and learning resources in the app.
Achieving Balance and Optimal Health
Through my experience with Signos, I realized the significance of maintaining stable blood sugar levels throughout the day. By striving to stay within the recommended range, I noticed improvements in various aspects of my well-being. These included enhanced mental acuity, improved athletic performance, reduced cravings and hunger levels, and better sleep quality. Achieving balance in blood sugar levels became a key focus, and the Signos CGM served as a valuable tool in helping me reach this goal.
The Signos Experience: Pros and Cons
Pros
- Personalized insights into metabolic health: Signos provides individuals with personalized recommendations based on their unique glucose data, allowing for customized approaches to improving overall health.
- Real-time feedback: The continuous monitoring of blood sugar levels in real time offers immediate insights into the impact of various factors on metabolic health.
- Holistic approach: Signos takes into account not only food choices but also factors like exercise, stress, and sleep, providing a comprehensive view of one’s overall well-being.
- Professional guidance: Signos offers access to medical professionals and registered dietitians to provide expert advice and support on the user’s health journey.
Cons
- Cost – It’s not cheap – starting at $499 a month. The cost does significantly decrease with longer term plans. The price of Signos and similar CGM devices can be a deterrent for some individuals.
- Limited research for healthy individuals: While CGMs have proven effective for managing blood sugar in individuals with diabetes, there is limited scientific data on the benefits and optimal use of CGMs for healthy individuals.
- Potential obsession or negative impact on mental health: Wearing a CGM and closely monitoring blood sugar levels could lead to an unhealthy fixation on food and a negative impact on individuals with a history of disordered eating.
Why Would Non-Diabetics Want Continuous Glucose Data?
Recent studies reveal that non-diabetics have larger fluctuations in their glucose levels than previously thought, and finding ways to stabilize glucose proves beneficial for health in many ways, such as:
- Weight loss
- Weight maintenance
- Building muscle
- Consistent energy
- Optimal fueling strategy for peak athletic performance
- Lower and control inflammation
- High-functioning immune system
- Lower risk of chronic diseases
As we await further peer-reviewed studies on the potential advantages of using Continuous Glucose Monitoring (CGM) in individuals without diabetes, the Signos app emerges as a promising tool to offer valuable insights into various aspects of our daily lives. While the scientific community continues to explore and analyze the potential benefits of CGM for non-diabetic individuals, the Signos app stands ready to provide a glimpse into how everyday circumstances can impact our well-being. By leveraging the power of CGM technology, the Signos app allows users to gain a deeper understanding of their body’s response to different situations and to make informed decisions about their health. Even in the absence of extensive research, the Signos app offers a unique opportunity for self-reflection and personal growth, enabling users to explore the potential connections between their lifestyle choices and their overall wellness.
Is Signos Worth It?
The decision to invest in a Signos CGM or similar device ultimately depends on individual circumstances and goals. For those seeking a deeper understanding of their metabolic health and the impact of various factors on blood sugar levels, Signos can provide valuable insights and guidance. However, the cost and potential psychological impact should be carefully considered before making a purchase. It is important to approach CGMs as a tool for information and empowerment rather than an obsession or replacement for healthy lifestyle choices.
In conclusion, my experience with the Signos Continuous Glucose Monitor offered valuable insights into my metabolic health and the impact of food, stress, sleep, and physical activity on blood sugar levels. By leveraging the real-time data provided by Signos, I was able to make more informed decisions about my diet and lifestyle, ultimately aiming for improved overall well-being. While Signos may not be necessary for everyone, it can be a useful tool for those looking to gain a deeper understanding of their body’s response to various stimuli.
