The Ultimate Guide to a Diabetic Diet: What to Eat, What to Avoid, and Tips for Success
If you have type II diabetes or prediabetes, you already know that your diet plays a major role in managing your blood sugar levels. But a healthy diabetic diet isn’t just about avoiding sugar and cutting carbs—it’s about choosing the right foods and making smart lifestyle choices to keep your blood sugar steady and your body healthy.
What Is a Diabetic Diet?
A diabetic diet focuses on eating nutritious foods that help regulate blood sugar levels while avoiding those that can cause spikes and crashes. When you consume carbohydrates, your body breaks them down into sugar molecules, which are then transported by insulin into your cells for energy.
For people with diabetes, this process doesn’t function properly. Either the body doesn’t produce enough insulin or the insulin isn’t used efficiently, leading to high blood sugar levels. While medications can help, following a balanced diet is essential to managing diabetes effectively.

What Foods to Eat?
The best diet for diabetics should include a mix of nutrient-rich, low-carb ingredients, including non-starchy veggies, protein foods, and heart-healthy fats. Other fiber-rich foods that contain a moderate amount of carbs like whole grains, legumes, nuts, and seeds can also be included in limited amounts as part of a diabetic/prediabetic diet.
One of the best ways to manage blood sugar levels effectively is to fill your diet with nutrient-rich whole foods. Here are some of the top choices:
Foods high in fiber: High-fiber foods help slow down glucose absorption, regulate your blood sugar levels, and support detoxification. Aim to eat at least 30 grams of fiber per day, which can come from vegetables (like Brussels sprouts, peas, and artichokes), avocados, berries, nuts, and seeds, especially chia seeds and flaxseeds.
Foods high in chromium: Chromium improves glucose tolerance and supports insulin function. Foods high in chromium include broccoli, raw cheese, green beans, brewer’s yeast, and grass-fed beef.
Magnesium-rich foods: Magnesium plays a role in glucose metabolism and helps regulate blood sugar. Foods like spinach, chard, pumpkin seeds, almonds, yogurt, and black beans are great sources.
Healthy fats: Medium-chained fatty acids found in coconut oil can help balance blood sugar levels. Other beneficial fats include coconut milk, ghee, grass-fed butter, avocados, and olive oil.
Clean protein: Protein foods have a minimal effect on blood glucose levels and help slow down sugar absorption. Top sources include wild-caught fish (rich in omega-3 fats), grass-fed beef, organic chicken, lentils, eggs, and bone broth.
Foods with a low glycemic load: These foods prevent rapid spikes in blood sugar. Good choices include non-starchy vegetables, berries, nuts, seeds, avocados, coconut, organic meat, eggs, and wild-caught fish.
Beneficial spices and beverages: Cinnamon and cardamom help regulate blood sugar levels, while beverages like water, unsweetened coffee, and tea (especially rooibos tea) offer anti-diabetic potential.
There are also several foods you can enjoy in moderation, provided they fit within your daily carbohydrate allotment:
Nuts: Almonds, pistachios, walnuts, macadamia nuts, etc.
Seeds: Chia seeds, flax seeds, hemp seeds, etc.
Fruits: Apples, berries, oranges, bananas, pears, etc.
Dairy products: Dairy milk, kefir, cheese, and yogurt from goat’s, sheep, or A2 cows.

What Foods and Drinks to Avoid?
It is as important as loading your plate with healthy whole foods is limiting foods that can spike your blood sugar levels. Here are some foods to avoid:
Refined sugar: Sugary beverages like soda and fruit juices rapidly increase blood sugar. Even natural sweeteners like honey and maple syrup should be used sparingly.
Grains: Gluten-containing grains, such as wheat, can contribute to blood sugar spikes and inflammation. Removing all grains for 90 days may help reset your system before reintroducing sprouted ancient grains.
Conventional cow’s milk: A1 casein in conventional cow’s milk can trigger inflammation and immune responses.
Alcohol: Excessive alcohol consumption can raise blood sugar and cause liver toxicity.
Hydrogenated oils: Vegetable oils like soybean oil, cottonseed oil, and canola oil have been linked to diabetes and inflammation.

Supplements for Diabetes Management
Several supplements have been shown to help reduce blood sugar levels, especially when paired with a nutritious diet and healthy lifestyle.
Probiotics: Improve glucose metabolism and reduce fasting blood sugar levels.
Magnesium: Enhances insulin sensitivity and lowers fasting blood glucose.
Chromium: Supports insulin function and reduces hyperglycemia.
Fish Oil: Lowers triglycerides and improves insulin sensitivity.
Alpha Lipoic Acid (ALA): Helps turn glucose into energy and improves nerve function.
Bitter Melon Extract: Supports blood sugar regulation and reduces diabetes-related complications.
Berberine: Shown to be as effective as metformin in lowering blood sugar levels.
Meal Plan Tips for Managing Diabetes
Plan Out Your Meals: Keep a balance of healthy fats, protein, and fiber in every meal. Methods like carb counting and the plate method can help manage intake.
Practice Meal Timing: Research suggests eating starchy vegetables in the morning, whole grains in the afternoon, and dark vegetables with protein in the evening can improve long-term health outcomes.
Eat More Fiber: Fiber slows down sugar absorption and supports gut health.
Pick High-Quality Protein Sources: Lean proteins help stabilize blood sugar and keep you full.
Incorporate Healthy Fats: Good fats improve insulin sensitivity and blood sugar control.
Exercise Regularly: Physical activity supports insulin function and helps manage blood sugar.
Risks and Side Effects of a Diabetic Diet
A well-balanced diabetic diet is generally safe, but some considerations include:
Low Blood Sugar (Hypoglycemia): If taking medication, monitor carb intake to avoid low blood sugar.
Nutrient Deficiencies: A varied diet is necessary to prevent deficiencies.
Digestive Issues: Increasing fiber too quickly can cause bloating. Introduce it gradually.
Final Thoughts
A diabetic diet should be built around nutrient-dense whole foods, including non-starchy veggies, high-quality protein, and heart-healthy fats. There are various methods to balance carbohydrate intake, such as the plate method and carb counting. In addition to a proper diet, incorporating regular exercise and supplements can help maintain healthy blood sugar levels. By making sustainable changes, you can manage diabetes effectively and improve overall well-being.
