The science of glucose monitoring and weight loss

High blood sugar boosts insulin production, which curbs your ability to burn fat. That’s why managing your glucose helps you lose weight sustainably—in a way that calorie counting and diet cycling never could.

Wear a continuous glucose monitor (CGM) once, and January’s AI will continue to provide glucose estimates even after you remove it.

See how different foods would impact your blood sugar before you eat them


Compare the glucose impact of different foods

Get a customized set of daily targets to eat, move, and sleep in precisely the way you need to control your weight.

“I learned how to structure my eating to help my body respond better, especially increasing fiber significantly and intermittent fasting. Having the real-time data to see what did and didn’t work was fantastic.”

“Not only did I discover how the foods I was eating affected my blood sugar, but I also came to see that I was most likely pre-diabetic. Ultimately, I lost about 50 lbs and have dramatically changed my mood and energy levels.”
