The Study
Improvement in the metabolic markers of prediabetic subjects due to the partial substitution of Taiken9 rice by RD43 rice in their daily diet: a randomized clinical trial.
This study gave some people a special kind of rice and others regular rice to see what happened. After 12 weeks, the people who ate the special rice had better blood sugar numbers. But we can't say for sure the rice caused it because they knew which rice they were eating, and not many people were in the study.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — losing weight and lowering blood sugar can delay or prevent type 2 diabetes, even without changing cholesterol.
- 2People who ate RD43 rice lost 2–3 kg, lost 2–4 cm around their waist, and lowered their blood sugar and insulin levels — but their cholesterol didn't change.

White rice with different starch structures leads to different rises in blood glucose and insulin after eating, even when the total amount of carbohydrates, protein, and fat is the same.
Replacing regular rice with RD43 rice for 12 weeks in adults with prediabetes does not change cholesterol or triglyceride levels, even though it may affect blood sugar and body composition.
Adults with prediabetes who eat RD43 rice for 12 weeks have a 25–30% lower HOMA-IR value than those who eat Taiken9 rice, showing improved insulin sensitivity without changes in lipid levels.
Eating RD43 rice for 12 weeks lowers HbA1c levels in adults with prediabetes and does not change lipid levels.
In adults with prediabetes, substituting two daily meals of high-glycemic rice with a low-glycemic rice containing 14.1 g of undigestible starch for 12 weeks lowers fasting blood glucose, insulin, HbA1c, HOMA-IR, body weight, BMI, total fat mass, and waist circumference.
In adults with prediabetes, replacing two meals per day with RD43 rice for 12 weeks leads to an average weight loss of 2–3 kg and a waist reduction of 2–4 cm, regardless of changes in blood lipid levels.
