But in recent years, glucose has become one of the trendiest biometrics to track for people striving to optimize their health.
That’s in large part because of the increasing accessibility of a tool called a continuous glucose monitor, or C.G.M.
C.G.M.s monitor levels of glucose — the body’s main source of energy — in real time.
A tiny needle-like sensor sticks into the skin and reads glucose levels in the fluid between cells.
Now, there are at least five companies that market and sell apps and C.G.M.s to people without diabetes, claiming that knowing your glucose levels can help you lose weight and improve your health.
