IL6 and fatty liver disease: The oligofructose group showed histological improvement, including a significant reduction in hepatic steatosis (p = 0.016) and a decreased NAS score.Bifidobacterium abundance significantly increased (p < 0.05), while Clostridium cluster I and XI significantly decreased (p < 0.05).IL‐6 and TNF‐α levels decreased, but the difference did not reach statistical significance due to the small sample size.No significant improvement in liver fibrosis was observed.Body weight and BMI remained unchanged between groups, indicating that improvements were independent of weight changes.
