Why monitor glucose?
Glucose monitoring has been promoted by well-liked well being podcasters Peter Attia and Andrew Huberman.
It has additionally been given huge publicity by French biochemist Jessie Inchauspé, who, underneath the alias Glucose Goddess, promotes books, recipes and dietary supplements designed to stabilise glucose ranges.
In a latest YouTube video, she stated although “there are a whole lot of upsides” to sporting a CGM, she “doesn’t advocate all people put on one” as a result of they’re a medical system supposed for individuals with a medical situation, and likewise stated that individuals don’t want the monitor to concentrate to what they’re consuming and the way they’re feeling.
