Frequently Asked Questions
Your Questions Answered
Signos is the first tool of its kind for weight management. Questions were bound to happen, so here’s the short list.
Shop NowSignos is a real-time metabolic health platform that combines an AI-powered app with a continuous glucose monitor (CGM). Your glucose data is sent directly to the app and combined with hundreds of millions of data points to predict responses to food and movement, track trends, log meals, track your weight, and access science-backed guidance to build sustainable, glucose-stable habits. You can also sync with Apple Health, Google Health Connect, smartwatches, and smart scales for a more complete view of your health.
Signos uses glucose data and millions of data points from logged meals, workouts, and other habits to deliver personalized guidance. When something you eat spikes your glucose, the app can suggest the right type and intensity of movement (based on your history) to help bring it back down. Over time, keeping your glucose more stable can lead to better energy, sharper focus, improved metabolic health, reduced risk of chronic conditions, and sustainable weight management.
Read more about how Signos works.
Yes, when used consistently, CGMs (also known as biosensors) can support healthy, sustainable weight management by helping you understand how your body responds to food, exercise, and daily habits in real time.
Research shows that 87% of CGM users change their food choices based on glucose feedback, and nearly half are more likely to move their bodies when they see a spike. Over 90% of users say CGMs help them lead a healthier lifestyle.
By showing you when your glucose rises or crashes, CGMs make it easier to recognize patterns, like cravings driven by glucose dips or energy crashes, and to respond with small, effective adjustments. This kind of insight can help you delay eating when your body still has fuel to burn, choose foods that support more stable glucose, and use short bursts of movement to bring high glucose levels back down.
Signos takes that a step further by using your personal glucose data, meal logs, and workout history to suggest what to eat next or how to move, so you’re not guessing. With consistent use, CGMs paired with in-the-moment guidance can help retrain your appetite, reduce overeating, and build habits that support long-term weight and fat loss.
For the latest information regarding the science behind glucose, insulin, fat storage, and weight loss, read The Scientific Evidence for Using CGMs for Weight Loss.
Possibly, but it depends on your HSA/FSA provider. Coverage varies, so check with your provider to confirm whether CGMs and wellness programs like Signos are eligible.
Please note: Signos is not responsible for reimbursement, and the cancellation policy and terms still apply, even if your provider does not approve coverage or reimbursement.
If weight loss is your goal, consider the amount of weight you’d like to lose and the recommended pace of 1 to 2 pounds per week. For example, a 25-pound weight loss goal is typically well supported by a 6-month plan. All plans give you full access to the Signos platform and behavior change program for the duration of your subscription.

Signos indications: The Signos Glucose Monitoring System is an over-the-counter (OTC) mobile device application that uses an integrated Continuous Glucose Monitor (iCGM) intended to continuously measure, record, analyze, and display glucose values in people 18 years and older, not on insulin. The Signos Glucose Monitoring System helps to detect normal (euglycemic) and low or high (dysglycemic) glucose levels. The Signos Glucose Monitoring System may also help the user better understand how lifestyle and behavior modification, including diet and exercise, impact glucose excursions. This information may be useful in helping users to maintain a healthy weight.
The user is not intended to take medical action based on the device output without consultation with a qualified healthcare professional.
See user guide for important warnings and precautions.
STELO IMPORTANT INFORMATION: Consult your healthcare provider before making any medication adjustments based on your sensor readings and do not take any other medical action based on your sensor readings without consulting your healthcare provider. Do not use if you have problematic hypoglycemia. Failure to use Stelo and its components according to the instructions for use provided and to properly consider all indications, contraindications, warnings, and cautions in those instructions for use may result in you missing a severe hypoglycemia (low blood glucose) or hyperglycemia (high blood glucose) occurrence. If your sensor readings are not consistent with your symptoms, a blood glucose meter may be an option as needed and consult your healthcare provider. Seek medical advice and attention when appropriate, including before making any medication adjustments and/or for any medical emergency.
