on the Highs and Lows of Continuous Glucose Monitors

The soundbite summary: Using a continuous glucose monitor (CGM) is like determining if a business is profitable by watching individual transactions of revenue and expenses without ever putting together a Profit & Loss statement. It’s both too much and too little data at the same time.

Topics include:

  • Why blood sugar is important, how it’s regulated, and problems with hyperglycemia or hypoglycemia
  • What’s different about diabetics and why they are helpful in insulin-dependent cases
  • Why Continuous Glucose Monitors (CGMs) are not helpful for weight and health goals for otherwise healthy individuals
  • Why CGMs could drive positive behavior change regardless of the data
  • Why CGMs could lead to food neuroses
