Prebiotics/Inulin for Appetite Control

B

A 12-week RCT (n=48) found oligofructose (21 g/day) reduced body weight by 1.03 kg with reduced ghrelin and increased PYY. Meta-analysis of 26 RCTs found significant weight and BMI reductions through increased SCFA production and improved gut-brain satiety signaling.
