The big problem is, if you fail to follow DUK's prejudices you will probably fail your assignment.
IME Type 2 is highly genetic. A small but significant proportion of sufferers have symptoms going back to childhood which are often ignored when they do not demonstrate Type 1 (someone I know actually failed a Glucose Tolerance test as a child and her parents were told to give her a low carb diet without being told why. She didn't rediscover the fact that she was actually diabetic until AFTER her first heart attack). Many patients probably have diabetes, or at least prediabetes, for ten years or more before being diagnosed, and already have significant damage. it is NOT caused by being fat and lazy, more often than not the fatness and lazyness is a symptom of carbohydrate intolerance, which came first. 20% of Type 2s are not overweight. 80% of obese people are not diabetic.
Two good papers, one old one new, about the Diabetic Progression

Medscape needs you to register but they don't spam you. The CME papers are mostly summations of "What every doctor should know" written by experts in their field BUT check the Discolsures at the end, some of them are little more than advertising puffs for one or another drug company.
The "epidemic" of Type 2, obesity and cardiovascular disease has followed hot on the heels of the adoption of the Heart Healthy diet, which clearly isn't.
