According to Dr. B's book dietary protein has nothing to do with kidney damage. Unless your blood sugar's are still high. Damage only occurs to the kidney's when the blood sugar's are high. Do you have his book? His website might hvae info about this. I wasn't worried about protein intake, then my therapist expressed concern and so I went into Dr. Bernstein's book and read what he says about it. Just like dietary fat doesn't cause high cholesterol or body fat, dietary protein doesn't cause kidney damage. Not alone. There have to be other factors - i.e. high blood sugar.
It would be a really good idea for you to get Dr. B's book "the Diabetes Solution" if you haven't already. I trust his info - the man has had Diabetes since 1946!
A lot of this is common sense, but you have to have the disease and experiment with yourself to really understand the relationship between carbs/food, exercise, and BG for your body. I for one have learned that I can't eat low-fat products. They contain more sugar per serving than their full fat counterparts and the fat isn't there to temper the effects of the carbs. This could be one main reason why I have T2 diabetes, possible renal failure, high blood pressure, yet my cholesterol is actually improving.
I have eaten high fat for years, and if I can give up the sugar forever I know the other health problems will improve as well.
I don't weigh over 300 and have these health problems because of fat or calorie intake, I have it because I binge on sugar and chips for months/years at a time.
Sorry this is so long and rambling. I hope that it helps some.
