The 3 claims about resistant starch
Each keeps its own verdict — we never average them away.
Does resistant starch lower blood sugar after a meal?
Strong support Yes for the post-meal spike, but its longer-term fasting effect is small and needs fairly large daily doses.
Does resistant starch help your body handle blood sugar?
Contested Unclear. Some small trials found improvement, but pooled analyses and a 12-week diabetes trial found no consistent effect on insulin resistance. Blood-sugar measures respond more reliably, and a benefit limited to insulin-resistant people is not established.
Does resistant starch help you lose weight?
Leans against Probably not — most trials show little to no weight loss, with one small promising study not yet replicated.
