Optimal CGM Target Ranges For Non-Diabetics

Why Wear a CGM?

Continuous Glucose Monitors aren't just for diabetics anymore.

They provide real-time data on how your body reacts to specific foods, sleep, and stress.

Fasting Baseline

For optimal metabolic health, your fasting glucose should sit between 72–85 mg/dL.

Anything above 90 mg/dL consistently is an early warning sign.

Post-Meal Spikes

Spikes are normal, but they should be controlled.

Aim to keep your glucose under 110 mg/dL after meals, peaking at no more than 140 mg/dL.

Time In Range

The most crucial metric is Time In Range.

You want to be in the strict 70–110 mg/dL window for at least 90% of your day.
