Nutrition tracking and biofeedback with Supersapiens

So I won a 3 month supply of continuous blood glucose sensors and I have had all sorts of issues related to fuelling. I’ve chosen to eat predominantly low carb just because I have a gluten sensitivity, sensitive teeth and a really poor family history for diabetes.

The monitor has only been on for a day so far but I’m intrigued to see what different fuelling strategies do for my performance. Does anyone else have experience of nutrition tracking/ blood glucose monitoring during and after workouts? What have been your insights?

Curious to hear about your 2 month experience? Unfortunately, supersapiens is not available in the US, but I’m VERY intrigued by what insights can be gleaned from a CGM for long endurance fueling. Just spoke to my GP today, and hoping to begin my course of discovery on how food choices affect my glucose levels in the next week. I’m not diabetic, nor pre-diabetic, but I’ve been convinced this is a “must have” device to “crack my fueling cod”.

We tested it a bit. A few downsides:

  • signal is quite delayed / dampened because you don’t measure in the blood, rather in the tissue.
  • when you are not diabetic, glucose regulation works quite well, so there are rarely clear spikes up and down.
  • when the sensor shows a low signal you are usually already really feeling it yourself.

I would not throw money at a company who wants to use marketing to sell a product for diabetics to a bigger audience.
