Google Launches Insulin Resistance Tracking for Pixel Watch

Google has introduced a new health feature for its wearable devices that tracks insulin resistance over time, marking a first for consumer technology companies in the race toward comprehensive metabolic monitoring. The tool, called Insulin Resistance Trends, debuted alongside the Pixel Watch 5 at a company event in New York on August 13, 2026. It is part of a broader suite of health tools named Health Guardian, which combines artificial intelligence with data from the watch's sensors to identify subtle physiological shifts that may signal a person is sliding toward diabetes before a formal diagnosis.
