How to Use a CGM to Reverse Prediabetes (and Prevent Diabetes)

If you've been diagnosed with prediabetes, you are at a crucial crossroads. The good news? Prediabetes is reversible — and one of the most powerful tools to help you succeed is a Continuous Glucose Monitor (CGM).

In this blog, we'll show you how using a CGM — even without diabetes — can help you lower your blood sugar, reverse insulin resistance, and stop the progression to type 2 diabetes.

At CGM-Doctor.com, we specialize in using CGM technology like the Dexcom Stelo to empower individuals to reclaim their health. And now, CGMs are available over the counter without a prescription! Learn more at CGM-Doctor.com.

Why Prediabetes Matters (And Why You Must Act Now)

Prediabetes means your blood sugar levels are elevated but not yet high enough to be diagnosed as diabetes. However, without intervention, up to 70% of people with prediabetes eventually develop type 2 diabetes.

By tracking and stabilizing your glucose levels using a CGM, you can take control before it’s too late — and potentially avoid diabetes altogether.

How a CGM Can Help Reverse Prediabetes

A Continuous Glucose Monitor provides real-time data about how your blood sugar responds to food, exercise, sleep, and stress. Instead of guessing, you gain personalized insights to make smart changes immediately.

Key Benefits of Using a CGM for Prediabetes:

Identify foods that spike your blood sugar
Flatten glucose spikes to reduce insulin surges
Improve insulin sensitivity naturally
Personalize your diet, exercise, and lifestyle strategies
Track progress toward reversing prediabetes

At CGM-Doctor.com, we guide you on how to use these insights to create sustainable changes that lead to lasting health improvements.

Insulin Resistance: The Root Cause of Prediabetes

Insulin resistance is when your cells no longer respond properly to insulin, causing higher blood sugar and higher insulin levels. Over time, this can exhaust your pancreas and lead to type 2 diabetes.

Reversing insulin resistance is key to reversing prediabetes — and monitoring your glucose in real time with a CGM is one of the most effective strategies available today.

Three Core Strategies to Reverse Prediabetes with a CGM

1. Low-Carb, Whole Food Diet

Eating a low-carbohydrate, nutrient-dense diet keeps your glucose and insulin levels stable.

Focus on non-starchy vegetables, healthy fats, and lean proteins
Avoid refined carbohydrates and sugars
Watch your CGM feedback to fine-tune your meals

2. Intermittent Fasting

Strategic fasting reduces insulin levels and improves metabolic flexibility.

Start with a 12-hour fasting window and increase as tolerated
Use your CGM to monitor safe and effective fasting practices

3. Strength Training

Building muscle increases glucose uptake and improves insulin sensitivity.

Incorporate strength exercises 2-4 times weekly
Track post-workout glucose patterns to optimize your regimen

Why Now Is the Best Time to Start Using a CGM

Thanks to new regulations, CGMs are now available over the counter without a prescription. That means you can begin using a Dexcom Stelo CGM right away to reverse your prediabetes and protect your future health.
