To combat type 2 diabetes, there is an urgent need for more effective treatments and therapeutic regimens.

This says that although rodent studies provide: Nonetheless, a causal role of dietary fat has never been definitively documented, in part because of inadequate animal models. The review by Rendina-Ruedy in BoneKEy Reports, 5, succinctly summarizes these aspects and provides guidelines on designing studies using DIO models for type 2 diabetes.

The route of administration was intraperitoneally unless otherwise indicated; intraveneously i. However, it takes years to develop frank diabetes. Inhe and his colleague Janis Fisler, also of UC Davis, surveyed of the literature and found that, of 35 papers that involved feeding mice a high-fat diet, only five used control diets that were identical save for their fat-versus-carbohydrate ratio.

But Justin Grobewho studies metabolism at the University of Iowa Carver College of Medicine, pointed out that even purified control diets can generate confusing results.

We do not transfer personal information internationally. The gut microbiota of SD rats was less abundant in Bacteroides and Prevotella but richer in Bifidobacterium and Lactobacillus comparatively to the gut microbiota of Wistar rats. The consequence is insulin resistance, thus directing lipids to the adipose tissue.

High-fat diets have been used to induce obesity in rodents and to study development of glucose intolerance and insulin resistance, characteristics of type 2 diabetes (T2D). These diets allow researchers to feed control and experimental mice foods with identical caloric content, replacing lost fat with increased sugar in control diets.
