Signos Review

90% of Signos members lose weight within their first month of service. If that’s not enough to pique your interest in this glucose-monitoring weight loss app, then I’m not sure what will be.

You can spend all the time you want searching for Google answers to questions like, “How long does it take to lower blood sugar?” or “Which low glycemic fruits are the best for weight loss?” Or, you can allow Signos data management tools to tell you how to structure your diet and exercise to reach your goals. 

Signos’ backbone comprises a continuous glucose monitor (CGM) and an AI-powered app that work in tandem to inform users of how they can change their behavior to improve their health.

In this Signos review, I will look at how the service works, what the plans are, what customers think about it, and more.

Signos Review

In this section of my Signos review, I’ll break down the basic features that the service provides to help you lose weight.

Signos is a weight-loss program, but it works differently than other plans. Rather than estimating what you need based solely on information and numbers you feed an app, Signos adopts a more holistic approach.

Of course, you need to measure what you eat and provide info with data concerning:

  • Height
  • Weight
  • Fitness goals
  • Intended weight loss
  • Exercise regimen

Signos also reads your body as it functions using a CGM. It measures your blood glucose levels and tells you the optimal range you should keep them in, depending on your goal. As such, Signos isn’t just for people who want to lose weight. You can also use the insight they provide you to:

  • Increase physical performance
  • Improve your overall health
  • Learn about your body and metabolism

Signos boasts several accountability features to help you reach your goals. These include:

  • Notifications whenever glucose spikes above its optimal range
  • Prompts reminding you to exercise and which type of exercise would be best given your current glucose levels
  • The predicted glucose spikes a meal will bring
  • Community features with other users

The Signos app has an array of trackers to help you keep tabs on other important facets of health and fitness. These include food, water, exercise, sleep, and weight. The more you input each, the more Signos will learn about you and thus better create plans designed just for you

The Signos cost varies depending on which plan you opt for. Each plan includes access to the Signos app, a CGM for the length of your membership, and a digital health assessment with one of the company’s professionals.

A 1-month membership costs $399 per month, a 3-month membership is $199 per month, and a 6-month program costs $159 per month.

How Does Signos Work?

Signos Review

In general, Signos’ process consists of three steps:

  1. Apply the Signos continuous glucose monitor to your body
  2. Earn live feedback from the monitor regarding particular foods
  3. Implement changes to your diet based on the feedback you’ve gained

Of course, the process is more nuanced than that, but the purpose of this Signos review is to give you a broad overview. 

Here’s an example of how the app and CGM work together. Let’s say you eat breakfast consisting of a bagel, cream cheese, and black coffee. You’ll input that data in Signos, and the app will tell you how those foods affect your blood glucose levels.

If your glucose levels don’t spike too much and remain within optimal levels, then you’re good. However, if your blood glucose levels rise too much then Signos will tell you to exercise since you have the energy to bring the levels back down. You can log your exercise to see how much it decreases your blood glucose. 

You’ll repeat that process to learn more about how your food, behaviors, exercises, and blood sugar interact. With that information, you can start making smarter choices that push you further toward your goals.

Who Is Signos For? 

Currently, Signos only operates in the United States. While there are some obvious demographics who could benefit from Signos (i.e., those who need to improve their diets), the service goes one step further; they have a questionnaire to identify whether or not their products are right for you.

Signos Reviews: What Do Customers Think?

Signos Review

The only aggregate Signos review score I could find online as of May 2023 was on Knoji where the company held an average of 3.8/5 stars based on more than 40 pieces of customer feedback.

For the most part, Signos reviews praised the service for its educational properties.

One customer wrote, “my personal experience with Signos is that the program was most beneficial as a a learning tool. I had a six month plan on a discounted rate (promotion?) that ran for about $900 or $950 for six months. (It does get cheaper the longer you subscribe). I did lose weight and kept up with the online Facebook and Instagram social communities Signos provided.”

That buyer went on to add, “Taught me to add strength training and exercise such as walking and jogging so that I didn’t lose so much muscle while losing weight. But as far as the benefit of using it but not for weight loss, again it was a learning tool for me.. some foods, in the right situations may not spike my blood glucose levels.”

That’s not to say that people didn’t lose weight. Plenty of Signos reviews mentioned weight loss, saying that the service helped them lose fat and keep it off

“No diet has worked for me long term. The Signos program is different because it shows me how food, exercise, and hydration affect my body in real-time. This program is changing my life!” said one customer.

I’ve included one final Signos review from Reddit that explains the value of the app – its ability to teach people about how food, exercise, and behaviors are integral to our health.

“It’s been just over a month. I have learnt so much. Not only have I lost 8 lbs but overall I feel better. I know when to eat, what not to eat. I think this has been the best investment I have made on myself.”

Is Signos Legit?

There weren’t many negative Signos reviews that raised concerns about the service’s legitimacy. As such, Signos is safe to work with.

Is Signos Worth It?

While there are correlations between weight and blood glucose levels, it’s not proven how much the latter matters with regard to weight loss. That’s more an issue of energy intake and output.

Signos can teach you about that information, and knowing more about your food and your habits can help you lead a healthier life, but the app does so for a steep price.

Although the majority of Signos reviews enjoyed the product, they said that the price was too much to sustain. Take that as you want, but there are plenty of less expensive alternatives for measuring energy intake and output. That being said, they omit CGMs, which may distinguish Signos enough to make it worthwhile.

How To Choose The Best Continuous Glucose Monitor

Before looking up a CGM device, consider these factors:

  • Is the device covered by insurance?
  • What other features does the device provide?
  • What are your intentions with the device?
  • Are you, or is anyone in your family, diabetic?
  • How easy is the device to use?
