Wearing a continuous glucose monitor (CGM) is a game-changer for understanding how your body responds to food, exercise, and lifestyle habits. But once you have the data, what should you actually focus on? Here are five key things to track in your CGM app to optimize your health and metabolism.

1. Fasting Glucose Levels

Your morning blood sugar—measured after at least eight hours without food—gives insight into your insulin sensitivity and overall metabolic health. A steady, healthy range is typically between 70-90 mg/dL. If your fasting glucose is consistently higher, it may indicate insulin resistance or stress-related glucose elevations.

2. Post-Meal Spikes

How high does your glucose go after eating? Ideally, you want to keep post-meal spikes below 140 mg/dL. Large spikes signal higher insulin production, which can lead to increased fat storage and energy crashes. If you notice frequent high spikes, try adjusting your meal composition by incorporating more protein, fiber, and healthy fats to slow glucose absorption.

3. Glucose Crashes

A sudden drop in blood sugar after eating can leave you feeling tired, irritable, and craving more carbs. If your glucose dips below 70 mg/dL or fluctuates wildly, it could be a sign that your meals are causing a rapid insulin response. Balancing your meals and incorporating protein-rich snacks can help stabilize these swings.

4. Glucose Stability

The fewer ups and downs, the better! If your glucose graph looks like a rollercoaster, it may be time to rethink your meal timing, carb choices, or stress management strategies. Consistently stable glucose levels mean better energy, fewer cravings, and improved overall well-being.

5. Exercise & Blood Sugar

Pay attention to how different types of movement affect your glucose. Strength training and post-meal walks often help lower blood sugar and improve insulin sensitivity, making fat loss easier over time. If you notice a spike during intense exercise, don’t worry—it’s a natural response, and your levels should regulate afterward.

Using a CGM isn’t about striving for perfection—it’s about learning how YOUR body responds so you can make informed choices. By tracking these key metrics, you can personalize your diet, exercise, and lifestyle for optimal health and sustained energy.
