The global epidemic of type 2 Diabetes Mellitus (T2DM) presents significant challenges to world health both in terms of financial costs as well as morbidity. Thus, considerable research has been focussed on the prevention or delay of the onset of T2DM. Type 2 Diabetes Mellitus (T2DM) is one of the most costly and burdensome of chronic diseases and is a global epidemic. Estimates by the International Diabetes Federation indicate that 387 million people have diabetes, and that this figure is expected to rise to 592 million by 2035 with an additional 175 million cases currently undiagnosed.
