Continuous glucose monitors (CGMs) provide real-time measurements of blood glucose, which is informative for understanding responses to food, exercise, and other factors.

“You can sort of hack it like you said with a glucometer at home, which a lot of people try to do, but I even made this mistake just as a aside real quick. I before I started wearing CGMs, I would check my, you know, finger stick all the time and I was testing different foods and I tested pineapple and checked it before I ate 30 minutes after I ate and an hour after I ate and it was like all 80. So I was like, "Wow, I barely moved at all from pineapple." And then the first time I tried a CGM, I tried it. Pineapple's like the highest spike I've ever had and I went to like 180 but came back down really fast which is good that that's a small reaction but I totally missed that spike with the glucometer because sometimes it happens fast and so you can't guess an estimated you know area under the curve. You can't guess what you're peaking at if you're using just a glucometer at home.”

“But it wasn't until I had a continuous glucose monitor on that I saw the change going way down during the exercise and then gluconeogenesis, whatever's kicking in, you know, it spiked back up. But I wouldn't have known that without that continuous, you know, data.”
