A CGM is a wearable sensor that tracks interstitial glucose levels in real-time, providing continuous data on how diet, exercise, stress, and sleep affect metabolic health. For healthspan, the goal is to use this biofeedback to minimize glycemic variability and postprandial glucose excursions, which are linked to reduced inflammation, oxidative stress, and the risk of age-related metabolic diseases.
Verdict
Powerful biofeedback tool for personalized metabolic health optimization.

Protocol
- Wear continuously for 4-12 weeks to establish personalized glycemic responses to food and lifestyle.
- Use periodically (e.g., quarterly) to reassess metabolic health and behavioral changes.
Flags
- Data requires careful interpretation to avoid overreaction to normal physiological fluctuations.
- May induce anxiety or obsessive tracking (orthorexia) in some individuals.
- Skin irritation or allergic reaction to the device adhesive is possible.
- Sensor readings can be inaccurate due to pressure (compression lows) or hydration status.
