TUCSON, Ariz. – I barely felt the continuous glucose monitor pierce my skin. Was it a prick, poke, or prod?

As a non-diabetic, this was a new experience for me. So what prompted me to “need” this device?

Diabetics have to keep a close eye on their glucose levels to manage their blood sugar effectively. While non-diabetics may not need to be as vigilant, being aware of how your body reacts to different foods, exercise, and stress can still be beneficial. This perspective is shared by experts at Canyon Ranch, a wellness resort in Tucson, Arizona, where guests in a special longevity program are encouraged to track their glucose levels over two weeks. This may help identify dietary changes that could improve their health.

According to Eric Williamson, the director of nutrition at Canyon Ranch, we could utilize the continuous glucose monitor data to boost my energy levels by avoiding energy spikes and crashes.

There’s been increasing discussion around these monitors, or CGMs, for non-diabetics. However, some health professionals remain skeptical, questioning if the effort is truly worthwhile.

Are CGMs Beneficial?

Continuous glucose monitors are small sensors placed under your skin that transmit data to your smartphone, providing insights into your blood sugar levels. Typically worn for one to two weeks, these devices are crucial for diabetics and can even be linked to insulin pumps. However, they can be expensive, costing individuals thousands of dollars each year.

Dr. Robert Shmerling from Harvard Health Publishing believes that the promotion of continuous glucose monitoring is outpacing the evidence supporting it for non-diabetics. He argues that current research does not substantiate the effectiveness of CGMs for those without diabetes. In contrast, Canyon Ranch claims that their testing follows well-established research principles, highlighting the ongoing debate within medical circles.

While the research may evolve, Shmerling currently suggests that it mainly shows fluctuations in glucose levels, with some individuals experiencing more variability than others.

Users of CGMs may find them useful. For example, Canyon Ranch guest Otis Greene was intrigued by the differences between his glucose readings and those of his Caribbean wife, who can enjoy starchy foods like rice and beans without as much blood sugar fluctuation, despite having higher cholesterol levels.

Notably, Greene has prediabetes, with a hemoglobin A1c reading of 6.3. His doctors been trying to lower this number with medication, but after monitoring his glucose levels and adjusting his habits, it dropped to 6.1. His doctor encouraged him to continue following the suggestions from Canyon Ranch and offered a prescription for a new monitor.

The Medical Debate

On the other hand, Valter Longo, Director of the USC Longevity Institute, sees the analysis of glucose data as a key component in future medical practices, especially as interest in longevity increases. The global longevity market is projected to grow significantly, from a valuation of $25.1 billion in 2020 to $44.2 billion by 2030, according to Allied Market Research.

For those hesitant to try a CGM, Williamson offers simple advice: Start your meals with protein. For instance, if you have chicken, sweet potatoes, and vegetables on your plate, consume the chicken first. This method could help stabilize your blood sugar levels.
