Does chicory-root fibre help you lose weight?
Contested Unclear. An industry-funded analysis and one trial found small weight losses, but three other trials at similar doses found none, so any effect is small and not reliably repeated.
Does inulin fibre boost the appetite-suppressing gut hormone GLP-1?
Leans against Probably not in people. Human trials that measured this hormone found no rise with inulin, and the support comes mostly from rat studies and one small, low-quality trial.
