Health Benefits of Zucchini Oat Muffins
- High in protein: Greek yogurt, eggs, and optional protein powder help stabilize blood sugar and keep you full. Research shows that a high-protein breakfast helps regulate appetite and energy throughout the day.
- High in fiber: Oats + zucchini = digestive support and long-lasting energy. Oats are a whole-grain powerhouse — rich in beta‑glucan fiber, minerals, and antioxidants — that help with fullness, cholesterol regulation, and gut health.
- Low in sugar: Lightly sweetened with maple syrup or honey—no refined sugar needed.
- Nutrient-dense: Zucchini adds vitamins A, C, and potassium without changing the flavor.
