Zhao Liping’s research on obese subjects showed that by reducing opportunistic pathogens such as Enterobacteriaceae and increasing the protective beneficial flora such as Faecalibacterium prausnitzii on an oligosaccharide rich legume and (gluten free) whole grain, low calorie Chinese traditional medicine diet, obesity and insulin resistance decreased significantly. On the special oligosaccharide rich diet, the morbidly obese subject not only eliminated E cloacae from detectable levels in fecal samples, but also lost over 100 lbs.

One morbidly obese subject’s gut microbiota contained high abundance of a particular toxic commensal known as Enterobacterer cloacae strain B29.   When the strain was transplanted into experimental germ-free mice, and obesity and insulin resistance developed. Bacterial endotoxins (LPS) were detected in the blood but not in controls.
