The growing use of continuous glucose monitors in people without diabetes: an evidence-free zone

Abstract

The use of continuous glucose monitors (CGMs) is growing among people without diabetes, and is being encouraged by CGM manufacturers and personalised nutrition companies alike. This article critically discusses the issues that may arise from this new trend, including pathologising normal post-prandial glucose excursions, the unnecessary avoidance of healthful foods and the risk of a glucocentric approach to nutrition which could inadvertently increase the risk of cardiometabolic diseases a person is trying to avoid. The theoretical benefits of CGMs in people without diabetes will be discussed, and recommendations for the evidence needed to help realise their potential will be made.
