Sawbones: Glucose Monitors
Summary
Hosts Justin and Sydney McElroy examine the recent FDA approval of over-the-counter continuous glucose monitors for non-diabetics, including children. They explain the medical history of diabetes and why these devices were originally designed for Type 1 patients managing insulin. The episode critiques commercial services like Signos and Nutrisense for marketing these monitors as weight-loss tools without robust evidence. The hosts argue that this trend, influenced by political figures like RFK Jr., risks eroding trust in medical providers and promoting disordered eating behaviors.
