SCFAs, including those increased by RS consumption, are thought to increase the levels of gut hormones (e.g., GLP-1, PYY) involved in appetite regulation.[1] Despite this, research examining the effect of RS on appetite, caloric intake, and weight status has mostly produced mixed or null results. A 2021 meta-analysis of randomized controlled trials found that in healthy young adults, RS caused short-term reductions in appetite, particularly at doses of at least 25 g daily.[2] However, chronic supplementation has not been found to reduce appetite or caloric intake[3] and there is little evidence to suggest RS reduces body weight.[4][1]
