What Is Signos Weight Loss?
Signos is a weight-loss program built on glucose data instead of a prescription. You wear a continuous glucose monitor, log meals and workouts in the app, and Signos shows how your body responded and what to try next.
It is a different product from the GLP-1 programs in our weight loss program rankings. Signos offers behavior feedback; the medication programs offer a prescriber and a drug. The Signos system is intended for adults 18 and older who are not on insulin.
The app blends sensor readings with logged meals, workouts and habits to predict how foods affect you. When something spikes your glucose, it can suggest a type and intensity of movement based on your history. It also syncs with Apple Health, Google Health Connect, smartwatches and smart scales.
The idea has a research basis. A Clinical Diabetes review of glucose monitoring as a behavior-modification tool describes how real-time feedback can change food and activity choices. That supports the mechanism, not any specific weight-loss result.
Signos reports that 86% of members report success in their first month. That figure is member-reported data from consistent users, so treat it as company data, not trial evidence.

Safety & What to Know
Signos is not intended to guide medical action on its own. Do not change any medication based on sensor readings without talking to your clinician, and avoid it if you take insulin or have problematic hypoglycemia.
Sensors are designed to last 15 days. In the study Signos cites, 77.9% lasted the full period, so roughly one in five may not.
Signos says any clinical services come from independent U.S.-licensed clinicians, who may prescribe or decline compounded GLP-1 medication. Signos does not dispense medication. Compounded semaglutide and tirzepatide contain the same active ingredients as branded drugs, but they are not FDA-approved and have not been through the same trials. The FDA has warned about dosing errors and quality problems with some compounded GLP-1s, so measure doses carefully and use a provider that works with licensed pharmacies.

|---|---|
| CGM hardware | Included |

Pricing varies by plan and promotion. Signos estimates doing it yourself at $800+ a month; that is its own estimate. The guarantee is a free coach audit of your data, not a refund, and the cancellation policy applies even if your HSA or FSA declines reimbursement.

How Signos Weight Loss Compares
altRx charges $89 for semaglutide and $149 for tirzepatide, and TrimRx offers compounded GLP-1 from $149 with a lifetime price lock. Signos costs more than either entry price but includes a sensor and dietitian support instead of a prescription.
Frequently Asked Questions
Our Verdict
★ 4.0 out of 5
Signos suits data-minded people who want to understand why a meal left them tired or hungry and what to change. At $127 a month with the sensor included it is priced as a program, but it will not replace medication for people who need it, and its results claims are company-reported.
