What is it?

The SIBO Bi-Phasic Diet e-book describes a protocol of diet, combined with specific gut healing and antimicrobial phases, created by Dr. Nirala Jacobi BHSc ND, Founder of TheSIBODoctor.com and Medical Director of SIBOTest.com, an online breath testing company in Australia.

The SIBO Bi-Phasic Diet is based on Dr. Allison Siebecker’s SIBO Specific Food Guide (found at www.siboinfo.com), a therapeutic diet combining the low FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols), and Specific Carbohydrate Diet.

The goal of the protocol is to help eliminate bacterial overgrowth from the small intestine.


Five Problems to Avoid

The SIBO Bi-Phasic treatment protocol and diet heal your gut faster, so you can avoid these!

1. Damage to the microvilli – the absorptive surface of the small intestine.

This can lead to malabsorption of nutrients. Microvilli are also responsible for the digestion of small starch molecules from food. When the microvilli are not working, the bacteria use these small starch molecules to cause fermentation.

This bacterial fermentation produces methane and hydrogen gas. Not only is this uncomfortable, but causes further damage to the microvilli.

2. Research has now shown that SIBO is a major cause of intestinal permeability or ‘leaky gut”.

Leaky gut is a condition where partially digested food particles are absorbed through the lining of the small intestines where they can cause an immune reaction.

Leaky gut also causes bacterial by-products to be absorbed – a major trigger for inflammation.

3. Leaky gut can also cause malabsorption of nutrients from your food.

Malabsorption can cause a wide variety of symptoms such as restless legs at night, fatigue, skin rashes, muscle aching as well as a host of digestive symptoms

4. The bacteria cause the motility of the small intestine to slow down or work improperly, causing further fermentation.

Restoring proper motility in the small intestines is a major focus of eliminating SIBO for good and your practitioner is likely to prescribe a “prokinetic” supplement or medication

5.  Many people who test positive for SIBO will also have SIFO.

A co-infection with fungal organisms is a condition known as SIFO (small intestine fungal overgrowth) – the SIBO Bi-Phasic diet helps to address this as well.

Phased Approach to SIBO Treatment

The Bi-Phasic Diet Protocol uses a phased approach to diet and treatment which limits the side effects of bacterial and fungal “die-off”.

The die-off process occurs when bacterial and fungal endotoxins released by their elimination are absorbed and cause physical symptoms. Die-off can be intense for some people.

Phasing the treatment through stages also aims to prioritize the repair of disturbed digestion over the use of antimicrobials.

That means you’ll feel better sooner!


Reduce – The first phase of the diet focuses on reducing fermentable starches and fibres, which is necessary to starve bacteria of their preferred fuel so they will begin to die-off.
Repair – Repairing the damage to the integrity of the intestinal lining, as well as repairing proper digestion, is a key element of this phase.


Remove – remaining overgrown bacteria and fungi from the small intestines: In this phase of the protocol, antimicrobials will be prescribed by your practitioner.
Even though still a low fibre diet, the protocol becomes a bit more lenient to allow for some bacterial growth so that antimicrobials are more successful.
Restore – The restoration of the normal motility of the small intestines is important to prevent relapse of SIBO. In this phase your practitioner may prescribe prokinetic medication
or supplements.

Practitioner Training

Welcome SIBO practitioners  

I first developed the SIBO Bi-Phasic Diet © to simplify my treatment strategies for Small Intestinal Bacterial Overgrowth.

Since then, practitioners from all over the world have approached me to find out more about the protocol that accompanies the diet.
