I had actually read about it last year. In the study, they used continuous glucose monitoring rather than glucose meter to track the blood sugar response to different foods precisely. They found that different people had different blood glucose response to different foods. The study only tracked participants for 1-2 weeks, but they do speculate on using personalized interventions devised from glucose measurements to treat and prevent such conditions as obesity and prediabetes. I decided to try it for myself.
