Glucose insights for your goals
Personal discovery
Using a CGM can help you build better eating and exercise habits to stay in a good glucose range.[1] What’s more, tracking your glucose and taking up habits that help keep you steady can support weight loss.[2,3]
Real-time feedback
Knowing your glucose data, minute-by-minute and making changes to your diet may help you move toward a healthy weight.[2,3] Over time, you can learn to fuel your body to minimize spikes, curb cravings, and feel fuller, longer.
Retrain hunger cues
Glucose crashes can trick you into thinking you need more food ASAP.[4] But seeing your real-time glucose data can help you understand the difference between true hunger and just a passing craving.[5]
Heart health
Glucose health is important for heart health.[6,7,8] And using a CGM has been shown to help you stay in a healthy glucose range more often.[9] So, show your heart some love.
