The Claim

Consuming 19.6 grams of resistant starch daily from heat-treated Dodamssal brown rice for two weeks causes a 1.5% reduction in HOMA-IR in obese adults, indicating a direct short-term improvement in insulin resistance independent of weight change.

In plain English

Eating 19.6 grams of resistant starch daily from heat-treated Dodamssal brown rice for two weeks reduces insulin resistance by 1.5% in obese adults, as measured by HOMA-IR, without requiring weight loss.

See the scientific wording

Consuming 19.6 grams of resistant starch daily from heat-treated Dodamssal brown rice for two weeks significantly reduces insulin resistance in obese adults, as measured by a 1.5% decrease in HOMA-IR (p=0.021), suggesting a direct, short-term benefit on glucose metabolism independent of weight change.

Why this might work

Undigested starch reaches the colon, where gut bacteria break it down into short-chain fatty acids. These fatty acids trigger gut cells to release a hormone that tells the pancreas to release more insulin and less sugar-stimulating hormone. At the same time, the fatty acids reduce inflammation in the gut and bloodstream, which allows the body’s cells to respond better to insulin and take up sugar more efficiently.

  1. Study: Effects of Consuming Heat-Treated Dodamssal Brown Rice Containing Resistant Starch on Glucose Metabolism in Humans

    People who ate a special kind of brown rice with lots of resistant starch for two weeks became better at using insulin to control blood sugar—even though they didn’t lose weight. This means their bodies handled sugar more efficiently.
