Fitbit Tracks Insulin Resistance & BP Without Cuffs

Fitbit Air and Edge devices are now equipped to provide users with insights into insulin resistance and blood pressure trends. These new features, part of Google's Health Guardian suite, offer deeper health monitoring capabilities beyond fitness and sleep tracking. Access to these advanced functions is limited to Google Health Premium subscribers, an annual service costing $100.

The technology analyzes metrics such as heart rate, activity, and sleep patterns to assess metabolic health changes. It also monitors blood pressure patterns and pulse without the need for a cuff, offering monthly insights. The insulin resistance feature, while not a direct glucose measurement, aims to identify precursor signs of type 2 diabetes by assessing biometric and metabolic patterns.

Google's multimodal model for insulin resistance tracking, trained on extensive data, provides notifications for elevated patterns. Users can also integrate Abbott CGMs for additional glucose monitoring. By extending these Health Guardian features to more accessible Fitbit models, Google aims to empower a wider user base with proactive health tracking tools.
