A number of lifestyle factors are known to be important to the development of type 2 diabetes including: obesity, physical activity, diet, stress, and urbanization.[1] Excess body fat underlies 64% of cases of diabetes in men and 77% of cases in women.[2] A number of dietary factors such as sugar sweetened drinks[3][4] and the type of fat in the diet appear to play a role.[5]
In one study, those who had high levels of physical activity, a healthy diet, did not smoke, and consumed alcohol in moderation had an 82% lower rate of diabetes. When a normal weight was included, the rate was 89% lower. In this study, a healthy diet was defined as one high in fiber, with a high polyunsaturated to saturated fat ratio, lower trans fats consumption, and a lower mean glycemic index.[6]
