Ask your doctor and you can always seek out a diabetes educator and a nutritionist to help with his diet.
Controlling BG levels is essential to preventing kidney complications, and has been shown to reverse disease in many cases.
However, it is important to note, that low-carb diets do not neccessarily mean high protein intake. And high fat does not neccessarily result in high lipids and cholesterol. In fact the opposite is the case with some low-carb diabetic diets.
Doctors often follow the 'book' to cover themselves.
One needs to research carefully, and talk to people who are actually succeeding in controlling BG levels within normal range, avoiding hypos, and lowering serum lipids, cholesterol, BP etc.
The only group of people I have found so far, that fall into this category, are those following Dr. Richard K Bernstein's methods for normalising blood sugars.I am sure there are others, but if you are serious about investigating for yourself, avenues of real success, then I would google: 'Bernstein Diabetes' and ask these guys how they do it. They have sample menus,recipes etc aswell as a wealth of personal experience, including with borderline or pre-diabetics.
Hope this is helpful;good luck.
