Going gluten-free can feel overwhelming at first—especially if you’ve spent years relying on breads, pastas, and pastries as part of your daily meals. But once you learn how to build your plate with naturally gluten-free foods, you’ll realize it’s not just doable—it’s delicious and energizing.

This 21-day gluten-free meal plan is designed to help you reset your body, reduce inflammation, and simplify eating. Each week focuses on balance: whole foods, easy prep, and satisfying flavors without any wheat, barley, or rye.

Why Go Gluten-Free?

People avoid gluten for a variety of reasons. For some, it’s a medical necessity due to celiac disease or gluten sensitivity. For others, it’s a lifestyle choice to reduce bloating, fatigue, and inflammation.

When you remove gluten, you often remove many processed foods too—leading to better digestion, improved energy, and clearer skin. The key is replacing those old carbs with nutrient-rich, naturally gluten-free options like rice, quinoa, potatoes, fruits, veggies, meats, and legumes.

What to Eat (and Avoid)

Eat Freely

• Fresh fruits and vegetables
• Meat, poultry, fish, and eggs
• Gluten-free grains: quinoa, rice, oats (certified gluten-free), millet, buckwheat
• Legumes: lentils, beans, chickpeas
• Nuts, seeds, and healthy oils (olive, avocado, coconut)
• Dairy (if tolerated)

Avoid

• Wheat, barley, rye, spelt, kamut, and triticale
• Regular breads, pasta, cereals, and pastries
• Processed foods with “hidden gluten” (soy sauce, soups, dressings, gravies, etc.)

Always check labels for “gluten-free” certification, especially on sauces, seasonings, and packaged snacks.
