The Prep Diet includes the 24 hours prior to your test. The goal is to starve the bacteria for a day in order to produce the best results when doing the test. SIBO bacteria love plant products and sugars, so the Prep Diet is very specific.
This diet, designed by Dr. Allison Siebecker, combines the low FODMAPs and SCD diets. This diet is the most restrictive but may relieve more symptoms in some people.
The low FODMAP diet was designed by researchers at Monash University to improve IBS symptoms. The diet focuses on removing carbohydrates that are high in fermentable oligosaccharides, disaccharides, monosaccharides and polyols.
The specific carbohydrate diet removes specific carbohydrates (polysaccharides, some oligosaccharides, disaccharides and polyols) and has been shown to be effective in healing IBD in one research study.
GAPs is a modification of SCD created by Dr. Natasha Campbell-McBride. It has a focus on the connection between the gut and the brain.
