The Bi-phasic SIBO diet was developed by Dr. Nirala Jacobi to starve bacteria in the small intestine of their fuel source.The purpose of the SIBO diet is to reduce the fermentable starches and fibers which feed bacteria that have overgrown in the small intestine. By reducing the fermentable starches and fibers bacteria will begin to die as they are deprived of their fuel source thus helping to reduce bacterial overgrowth in the small intestine. ~ Didem
