A little-known tech that Fitbit + Apple are exploring could be the answer to healthy eating and peak performance
Geoffrey Woo hasn't gone back to Burger King since he saw the numbers.
The trim 30-year-old was at the airport one afternoon when he strayed from his healthy diet and ordered an old-time favorite: a Whopper, fries, and a Coke. Everything seemed fine until a few hours later, when he checked a device usually used only by people with diabetes.
The trend lines on the small square display, which tracked Woo's blood-sugar levels, normally stayed fairly flat. But after the Burger King meal, they spiked to three times their normal levels.
Woo doesn't have diabetes, but he says being without that device, known as a continuous glucose monitor, or CGM, feels like losing an organ.
