Higher relative abundance of the gut microbial genus Blautia is significantly and inversely associated with visceral fat area (VFA) in adults, regardless of sex.
Visceral fat is linked to the abundance of Blautia bacteria in your gut. While you cannot directly 'dose' Blautia like a supplement, this genus produces beneficial short-chain fatty acids (butyrate, acetate). Supporting Blautia likely involves a diet rich in diverse fibers, as fiber intake was a key variable in the study's adjustments. Focus on whole-food, high-fiber diets to support a microbiome profile associated with lower visceral fat.
Blautia was the only gut microbe significantly and inversely associated with VFA, regardless of sex.
Why this rating
Large cross-sectional observational study (n=1001) with replication in a confirmation group, but causality cannot be established.

- 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
