Baseline intestinal microbiome composition predicts the magnitude of weight loss and improvement in hepatic steatosis in response to a calorie-restricted diet, independent of dietary compliance.
If you are struggling to lose weight on a standard calorie-restricted diet despite good adherence, your gut microbiome might be resisting the change. This is not a personal failure. Future testing may identify if your specific microbial profile (e.g., high levels of Escherichia/Shigella or Klebsiella) predicts poor response to simple calorie restriction, potentially guiding you toward other interventions like bariatric surgery or targeted microbiome modulation.
Baseline microbiome profiles were able to predict which patients lost at least 5% of their body weight with an AUROC of 0.80.
Why this rating
Prospective cohort study with a relatively small sample size (n=46 completers) and lack of external validation cohort, though statistical methods are robust.

- 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
