Why High-Protein Snacks Are Essential for CGM Beginners

When you’re just starting with a CGM, it’s easy to feel confused about which snacks keep your blood sugar steady. High-protein snacks play a key role here—they slow digestion, help prevent sudden spikes, and reduce cravings between meals.

Focusing on protein-rich options also supports the time in range goal, meaning more hours of stable glucose throughout the day. This isn’t just about avoiding highs and lows—it’s about feeling consistent energy and better control over your daily routine.

Choosing the right snacks can transform your CGM experience from stressful to manageable, giving you confidence in making food choices that genuinely help your body.
