| Outline of Final Research Achievements |
In this study, we found that rats fed soft diet on 3-h restricted feeding show glucose tolerance, insulin resistance, and lipid accumulation in the liver. These rats also demonstrated impairment of insulin signal transduction in the liver and increase in the number of islets compared with rats fed standard chow. We showed that lipid accumulation factors induced by hyperglycemia and hyper insulinemia also increase in rats fed soft diet. Taken together, it was thought that rats fed soft diet on 3-h restricted feeding could be a novel of type II diabetes without significant obesity like Japanese and Asian people.
