Getting to the bottom of why you are experiencing the symptoms your having. Are you ready to start your journey towards optimal health?

Tips for optimizing insulin levels

Balanced insulin levels are key for steady energy, fat metabolism, and hormonal balance. Achieving an ideal fasting insulin level of 3–4 µIU/mL supports metabolic health and resilience. These simple, effective habits help your body become more insulin-sensitive naturally.

1. Begin Each Meal with Vegetables

Start your meals with fiber-rich vegetables to slow glucose absorption and promote a healthy insulin response. Aim to fill half your plate with colorful, non-starchy veggies.

2. Prioritize Protein

Aim for about 1 gram of protein per pound of your ideal body weight daily to support muscle health and stable blood sugar levels, improving insulin sensitivity.

3. Include Healthy Fats

Add sources like avocado, olive oil, Balance Oil, ghee, nuts, seeds, or fatty fish at each meal to keep blood sugar and hunger stable.

4. Create Clear Meal Windows

Eat each meal within a 60-minute window and drink only water between meals. Even “healthy” drinks or chewing gum can trigger insulin release.
Example: Start breakfast at 8:00 AM, finish by 9:00 AM, then have only water until your next meal.

5. Optimize Fiber

Aim for 35–50 grams of fiber daily from a wide range of plant foods. Think “eat the rainbow”—diversity supports both your gut and insulin sensitivity.

6. Eliminate Processed Carbohydrates

Avoid bread, crackers, cookies, pastries, cereals, and packaged snacks that spike blood sugar. Choose whole, real foods instead.

7. Add Herbs & Spices

Cinnamon, turmeric, ginger, garlic, and fenugreek can naturally enhance insulin sensitivity and add flavor to your meals.

8. Drink Green Tea

Organic green tea supports metabolic health and has mild insulin-balancing and antioxidant effects. Aim for 1–3 cups daily.

9. Use Apple Cider Vinegar Before Meals

Mix 1 teaspoon to 1 tablespoon of apple cider vinegar (ACV) in 8 oz of water about 5–20 minutes before eating. Drink through a straw or rinse your mouth afterward to protect tooth enamel.

10. Eliminate Processed Sugar

Avoid sweetened drinks, desserts, syrups, and hidden sugars in packaged foods to prevent insulin spikes.

11. Prioritize Quality Sleep

Poor sleep raises cortisol and insulin resistance. Aim for 7–9 hours of nightly sleep with consistent bed and wake times.

12. Move Daily

Combine resistance training, walking, and light activity throughout the day to help your cells use glucose more efficiently.

13. Manage Stress

Chronic stress raises cortisol and disrupts blood sugar balance. Support your nervous system with breathing exercises, grounding, time in nature, or gentle movement.

Final Thoughts on Optimizing Insulin Levels

By adopting these habits, you can support healthy insulin levels, steady energy, and metabolic resilience. For personalized guidance and support, consider working with a functional medicine practitioner to tailor a plan specific to your needs.
