Chilling rice overnight and reheating it before eating makes your blood sugar rise much less after the meal because some of the starch turns into a form your body can’t digest easily.

Influence of resistant starch resulting from the cooling of rice on postprandial glycemia in type 1 diabetes
This study found that cooling rice overnight and reheating it makes it cause a much smaller blood sugar spike in people with type 1 diabetes — just like the claim says. The numbers match exactly, so it supports the claim.
