Faecal Microbiota Transplantation (FMT) from lean donors shows promise for improving insulin sensitivity in metabolic syndrome, but current human evidence is limited, small, and unreplicated.
FMT from lean donors may improve insulin sensitivity, but it is not yet a standard or proven treatment for diabetes due to limited and unreplicated human data. Do not pursue this outside of clinical trials.
LimitedQualifiesLOW confidence
the current evidence for FMT as a therapeutic tool to improve glycaemic control and/or insulin sensitivity is very limited
Why this rating
Based on a single small study (n=18) that did not report glucose levels and has not been replicated.

More from this paper
- Metformin's primary glucose-lowering mechanism involves altering gut microbiota composition to increase butyrate and propionate production and enhance GLP-1 secretion, rather than solely acting via hepatic pathways.Good
- Targeted delivery of propionate to the proximal colon improves glucose metabolism and reduces energy intake without requiring high fiber intake or a responsive gut microbiota.Moderate

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
