1-Day SIBO Bi-Phasic Diet Meal Plan

So there are many different diets used to treat or manage SIBO (Small Intestinal Bacterial Overgrowth), and the SIBO Bi-Phasic Diet is one them. It combines the low FODMAP diet and the Specific Carbohydrate Diet. The diet aims to reduce the side effects of the bacterial die-off that occurs when the bacteria are eliminated by antimicrobial or antibiotic treatment. The diet should only be followed for about three months while the SIBO is being treated.

I followed the diet for some months and found that it helped reduce my symptoms. Especially the bloating and abdominal pain! It is quite strict and can be challenging to follow, so I thought I’d give you an idea of what I would eat in a day.

Please remember that it can be challenging starting a new protocol and the SIBO Bi-Phasic Diet should be used as a guide for some people with tolerate some foods better than others. So it may be worthwhile having a chat to your health professional about whether this diet will suit you and your treatment.

Phases of the SIBO bi-phasic diet

Phase 1

  • Restricted – basic diet
  • Semi-Restricted – depending on symptoms or if you need extra energy, it adds starches (quinoa, white rice), more vegetables and fruit to the restricted diet

Phase 2

Some foods can be eaten freely and some have servings amounts per meal or per day, so check the list for the exact measurements, though I have listed the restricted amounts in the plan. Most people will begin with the Phase 1, Restricted Diet and see how they respond to it. These meal ideas are based on this section of the diet.
