Navigating Small Intestinal Bacterial Overgrowth (SIBO) can feel overwhelming, especially when it comes to diet. The SIBO Biphasic Diet, developed by Dr. Nirala Jacobi, offers a structured, two-phase approach to help manage symptoms and support treatment. This guide will walk you through the diet’s principles and provide delicious SIBO Biphasic Diet recipes to make your journey both manageable and flavorful.
The core idea is to first reduce fermentable carbohydrates that feed the bacteria and then gradually reintroduce foods while your gut heals. Understanding what to eat—and when—is the key to success. We will explore both phases, offering meal ideas and practical tips to help you feel confident in the kitchen.
SIBO Biphasic Diet
The SIBO Biphasic Diet merges principles from the Low FODMAP diet and the Specific Carbohydrate Diet (SCD). Its goal is to starve the overgrown bacteria in the small intestine, reduce inflammation, and repair the gut lining. The diet is divided into two distinct phases, each with specific food lists and objectives.
Phase 1: Reduce & Repair
This initial phase is the most restrictive. It lasts for approximately 4-6 weeks and focuses on calming the digestive system. The goal is to dramatically reduce the food sources for the bacteria, which helps to lower fermentation and alleviate symptoms like bloating, gas, and pain. Foods are limited to easily digestible proteins, fats, and a small selection of low-fermentation vegetables and fruits.
Phase 2: Remove & Restore
After the initial period, you transition to Phase 2. This phase continues for another 4-6 weeks and aligns with the “kill” phase of many SIBO treatment protocols (like antibiotics or herbal antimicrobials). While still restrictive, it allows for the reintroduction of some more fibrous vegetables, certain fruits, and fermented foods to help restore a healthy gut microbiome. Finding good SIBO Biphasic Diet recipes is crucial for staying compliant during this period.
Phase 1 Recipes: Simple and Soothing
During Phase 1, your meals will be simple but nourishing. The focus is on well-cooked, easy-to-digest foods. Think soups, broths, and simple proteins. Spices are generally limited to salt, pepper, and fresh herbs.
Sample Phase 1 Meal Plan
| Meal | Option 1 | Option 2 |
|---|---|---|
| Breakfast | Scrambled eggs with finely chopped spinach and chives. | A simple smoothie with approved protein powder, water, and a few blueberries. |
| Lunch | Baked salmon with a side of steamed carrots and zucchini. | Chicken and vegetable soup made with homemade bone broth. |
| Dinner | Simple ground turkey patties with a side of steamed green beans. | Pan-seared white fish with a squeeze of lemon and fresh dill. |
| Snack | A cup of homemade bone broth. | A handful of macadamia nuts (if tolerated and on your approved list). |
Phase 1 Recipe Spotlight: Soothing Chicken & Ginger Soup

- Stir in the fresh parsley and season with salt and pepper.
- Serve warm and enjoy the soothing benefits. This is a perfect example of a foundational SIBO Biphasic Diet recipe.
Phase 2 Recipes: Expanding Your Plate
As you move into Phase 2, you can start incorporating more variety. This phase allows for certain legumes (like lentils), more vegetables, and even some grains like white rice. It’s a great time to experiment with new SIBO Biphasic Diet recipes that feel more like “normal” meals.
Key Foods to Reintroduce in Phase 2
Your practitioner will provide a specific list, but some common additions include:
- Vegetables: Broccoli florets, cauliflower, asparagus, and bell peppers (cooked well).
- Fruits: More portions of low-FODMAP fruits.
- Legumes: Lentils and chickpeas, properly soaked and cooked.
- Grains: Small portions of long-grain white rice.
- Fermented Foods: Homemade 24-hour yogurt or sauerkraut (in small amounts to test tolerance).
Phase 2 Recipe Spotlight: Roasted Salmon with Asparagus and Lemon
This simple sheet-pan dinner is perfect for a weeknight meal. It’s flavorful, packed with nutrients, and compliant with Phase 2 guidelines.
Ingredients:
- 2 salmon fillets (about 6 oz each)
- 1 bunch of asparagus, tough ends trimmed
- 1 tablespoon olive oil
- 1 lemon, half sliced, half for juice
- 1 teaspoon dried dill
- Salt and pepper to taste
Instructions:
- Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
- Toss the asparagus with olive oil, salt, and pepper directly on the baking sheet. Arrange them in a single layer.
- Place the salmon fillets on the same sheet. Drizzle with a little more olive oil and squeeze the juice from half the lemon over them.
- Season the salmon with dill, salt, and pepper. Top each fillet with a few lemon slices.
- Bake for 12-15 minutes, or until the salmon is cooked through and the asparagus is tender-crisp.
- Serve immediately. This is one of the easiest and most satisfying SIBO Biphasic Diet recipes you can make.
Phase 2 Recipe Spotlight: Simple Lentil and Vegetable Stew
This hearty stew introduces legumes back into your diet in a gentle, well-cooked form. It’s a fantastic way to add fiber and plant-based protein.
Ingredients:
- 1/2 cup brown or green lentils, rinsed

- Add the rinsed lentils, broth, diced bell pepper, bay leaf, and thyme.
- Bring the mixture to a boil, then reduce the heat to a simmer. Cover and cook for 30-40 minutes, or until the lentils are tender.
- Remove the bay leaf before serving. Season with salt and pepper to your liking.
Tips for Success on the SIBO Biphasic Diet
Sticking to a restrictive diet can be challenging, but a little planning goes a long way.
- Meal Prep is Your Best Friend: Dedicate a few hours each weekend to chop vegetables, cook a batch of rice (for Phase 2), make bone broth, and portion out proteins. This makes weekday meals much faster.
- Embrace Bone Broth: Homemade bone broth is a cornerstone of the diet. It’s incredibly soothing for the gut lining and can be used as a base for soups or simply sipped on its own.
- Listen to Your Body: The food lists are guides, not absolute rules. Pay attention to how you feel after eating. If a specific food causes symptoms, remove it and try again later. Keeping a food journal can be very helpful.
- Work with a Professional: This diet is best followed under the guidance of a qualified healthcare practitioner, like a naturopathic doctor or functional medicine specialist. They can help you tailor the diet, manage treatment, and monitor your progress.
The SIBO Biphasic Diet is a powerful tool for managing SIBO. While it requires dedication, focusing on delicious and nourishing SIBO Biphasic Diet recipes can make the process more enjoyable. By prioritizing gut-healing foods, you are taking a proactive step toward reclaiming your digestive health.
Frequently Asked Questions (FAQs)
1. Can I drink coffee on the SIBO Biphasic Diet?
Generally, coffee is discouraged, especially in Phase 1, as it can irritate the gut lining. Some practitioners may allow one weak black coffee in Phase 2.
2. How long should I stay on the diet after my SIBO treatment is finished?
Your practitioner will guide you, but most people slowly reintroduce foods over several weeks or months post-treatment to ensure the gut has fully healed.
3. Are there any pre-made snacks I can buy?
Finding compliant pre-made snacks is very difficult. It’s best to prepare your own, such as a handful of approved nuts, olives, or homemade jerky.
4. What can I use to sweeten my food?
Stevia and very small amounts of honey (in Phase 2) are sometimes allowed, but it’s best to avoid sweeteners to help reduce cravings and starve bacteria.
5. Is alcohol allowed on the SIBO Biphasic Diet?
No, alcohol is strictly avoided throughout both phases as it is a gut irritant and can feed bacterial overgrowth.
