Keeping tabs on blood sugar throughout the day used to be the exclusive domain of people with diabetes. But in 2026, anyone can buy a user-friendly wearable device that provides minute-by-minute readouts on how their glucose levels respond to food and movement. These glucose numbers are increasingly being tracked by people who are healthy but want to lose weight or optimize their wellness. I am a behavioral scientist who has spent the past decade studying how real-time data captured through wearable sensors and mobile technologies can help promote a healthier lifestyle. I’ve found that for people who don’t have diabetes, using such a device for a few weeks can bring insight into how their body reacts to their eating patterns and daily habits. But researchers still don’t know how these fluctuations affect health for people who don’t have diabetes. In the absence of meaningful metrics for interpreting these numbers, monitoring a constant stream of data doesn’t directly help people make health-related decisions and can lead to confusion and needless anxiety. What are glucose levels – and why track them? Glucose is a type of sugar that circulates in the bloodstream after being absorbed from food. It is the body’s primary…

Wearable glucose monitors offer real-time data, but for healthy people no guidelines exist to interpret the numbers
