CGM Research Desk

The working file on CGM. Each claim below is rated on its own evidence.

In plain terms: every claim below has been checked against the published research and rated on how solid the evidence actually is, not just asserted. Established means multiple strong studies agree. Uncertain means the evidence is thin or conflicting. This file updates as new research comes in, so you can see exactly what's settled about CGM and what isn't.

Does continuous glucose monitoring provide meaningful metabolic or dietary insight for people without diabetes?

KnowYourPrime evidence rating Established Strong, consistent evidence supports the claim.

Continuous glucose monitoring in people without diabetes reveals glycemic patterns that reflect diet, lifestyle, and metabolic physiology.

Anchor-grade evidence affirms the core relationship.
Multiple supporting studies are consistent with the core relationship.

What would change this rating

A new core-hitting conflicting study, a retraction of an anchor, or a failed replication would lower this rating.

Does using a CGM change behavior in a way that improves glycemic outcomes for people without diabetes?

KnowYourPrime evidence rating Emerging Evidence currently favors the claim, but more confirmation is needed.

Using a continuous glucose monitor changes eating or exercise behavior in ways that measurably improve glycemic control for non-diabetic users.

Anchor-grade evidence affirms the core relationship.
An anchor study is present but its own reported finding does not cleanly affirm this claim, so it does not count toward the Established threshold.
The claim rests on a single anchor whose finding affirms it; a second independent affirming anchor is needed to reach Established.
