🔬 Health & Fitness Research

Google Pixel Watch 5 and Fitbit Air estimate insulin resistance from resting heart rate and sleep via Health Guardian. The inference is clever but unvalidated against blood work, so consumers get a trend signal that’s only meaningful if their HR and sleep patterns hold steady.

Marty’s Take:

Don’t buy Google Pixel Watch 5 today expecting Insulin Resistance Trends on day one: Google confirmed the feature ships this September, and it also lands on Pixel Watch 3 and Pixel Watch 4, not just the newest model. If you already own an older Pixel Watch, wait for the software update instead of upgrading hardware. For alternatives worth comparing now, see our best fitness tracker picks.
