Type 2 diabetes, on the other hand, is a dietary and lifestyle disease. In response to frequent high blood sugar, the body produces excessive insulin, which leads to insulin resistance—just as we stop being able to smell a particular odor in a room after a while, the body stops being able to respond to insulin’s signals after prolonged exposure to excess insulin. There is a clear association between type 2 diabetes and obesity, and weight loss often reverses this type of diabetes.
