This case report examined six patients with small intestinal bacterial overgrowth (SIBO), a condition where excessive bacteria grow in the small intestine, causing symptoms like bloating, abdominal discomfort, and potentially serious malabsorption issues. SIBO is typically diagnosed through breath tests that measure hydrogen gas produced by these unwanted bacteria when they ferment certain sugars.
The researchers tested whether a zero-carbohydrate "carnivore diet" consisting only of animal fats and proteins could eliminate SIBO by essentially starving the problematic bacteria that thrive on carbohydrates and fiber. Six patients followed this restrictive diet for periods ranging from two to six weeks, with breath tests performed before and after the dietary intervention.
The results were promising: five of the six patients who followed the carnivore diet for four weeks or longer tested negative for SIBO after the intervention. The one patient who only maintained the diet for two weeks showed significant improvement but not complete resolution. The theory is that by removing all carbohydrates and fiber, the diet deprived the overgrown bacteria of their preferred food source while still providing adequate nutrition through animal proteins and fats.
While these results are intriguing, this is a very small study that hasn't undergone peer review, so the findings should be interpreted cautiously. For patients dealing with SIBO or other gut health issues, this research suggests that targeted dietary interventions might offer an alternative or complement to conventional antibiotic treatments, though such restrictive diets should only be attempted under medical supervision.
