If you have ever worn a continuous glucose monitor and felt a wave of panic watching your blood sugar spike after lunch, this episode is for you. I want to show you how to read a CGM the way it is meant to be read, as a short-term teacher, not a source of daily anxiety.
A CGM is basically a home inspection for your metabolism. Like any inspection, it turns up findings that look alarming but mean nothing, alongside a few that genuinely matter. In this episode I walk you through what normal glucose actually looks like, why healthy people spike above 140 every day, and how to tell a real finding from an artifact like a compression low or the dawn phenomenon. We look at what the research really says about glucose monitors for non-diabetics, including the risk of tracking tipping into disordered eating, and why the device is almost never the problem. Then I give you the exact two-week protocol I use with my patients, with simple experiments to see how a post-meal walk, meal order, sleep, and stress each change your curve.
What you’ll learn in this episode:
Why healthy people see blood sugar spikes above 140 every day, and when a spike actually matters
How a short walk after meals flattens your glucose curve, and why meal order changes your after-meal spike
How stress and one bad night of sleep show up on a CGM with no food involved
How to spot false readings like compression lows, sensor lag, and the dawn phenomenon
What the science says about continuous glucose monitors for non-diabetics and metabolic health
The exact two-week CGM protocol I use with patients, and when to see your doctor instead
