AI Digital Twins Are Helping People Manage Diabetes and Obesity

WIRED

Rodney Buckley has lost 100 pounds in less than a year, not by using a GLP-1 drug but with the help of a digital twin. Last March, the 55-year-old retired firefighter turned village mayor of Third Lake, Illinois, was 376 pounds.

When his wife's employer started offering a program from startup Twin Health, he thought he would give it a try.









A Continuous Glucose Monitor Might Help You Lose Weight (2026)

WIRED

If you do not go on medication, you can manage the condition--a chronic metabolic disease that's characterized by elevated blood sugar levels--by exercising and watching what you eat (very, very closely).

Continuous glucose monitors (CGMs) like the Abbott Lingo and the Dexcom Stelo used to be available only by prescription.
