My first time using a glucose biosensor.

A few months ago, Continuous Glucose Monitoring (CGM) sensors were approved by the FDA for over-the-counter use, and I was immediately intrigued. I’m always on the lookout for new ways to track my health, and the idea of visualizing my blood sugar levels felt particularly compelling.

I’ve always considered myself a foodie—I genuinely love food. However, I’ve been largely unaware of how what I eat impacts my health. The concept of fasting, for example, has always made me uneasy; I just really enjoy eating.

For most people, a sense of satiation kicks in when the brain signals that enough food has been consumed to feel satisfied. For me, though, that signal doesn’t seem to work as it should. I often find myself eating far more than I need before I even begin to feel full.

When I saw that Lingo was offering a great discount on a one-month supply of glucose monitoring, I jumped on their Cyber Monday deal. It was the perfect opportunity to track my blood glucose levels and see if my constant hunger was related to low blood sugar.

Applying the glucose monitoring patch wasn’t painful, but the applicator looked a bit intimidating. The sensor’s needle, a few millimeters long, gave me pause—I almost reconsidered. However, I went through with it, and the process turned out to be pretty anticlimactic. It took about 60 minutes for the sensor to fully activate and start delivering near real-time data directly to my phone.

Over the next couple of weeks, I’ll update this post with observations and insights from my experiment.

One of the standout features of the Lingo app is its ability to analyze your patterns and assign a personalized "lingo target"—a number you aim to stay below. When the sensor detects a blood sugar spike, it accumulates lingo points, which count against your target
