Exploring the Impact of Wearable Continuous Glucose Monitoring on Glucose Regulation and Eating Behavior in Healthy Individuals: A Pilot Study

While continuous glucose monitoring (CGM) technology has been instrumental in managing diabetes, its potential impact on healthy individuals remains underexplored. This pilot study investigates the influence of wearing a CGM device on glucose regulation and eating behavior among healthy participants. Over approximately one month, participants utilized a wearable CGM device, and semi-structured interviews were conducted at the study's conclusion to gather insights. Analysis revealed a significant decrease in mean glucose levels and fewer glucose spikes during the study period for half of the participants. Interview findings supported the hypothesis that CGM usage positively affected behavior, with participants adjusting meal timing but not food choices based on real-time glucose readings. Some participants ignored glucose spikes due to their asymptomatic nature, indicating behavioral inertia. Nonetheless, they expressed intent to implement changes based on what they learnt in the experiment. This study offers initial evidence of CGM's potential as a behavioral moderation tool for improving glucose regulation among healthy individuals.
