Dr. Barnard's "Tackling Diabetes" is only for those willing to listen carefully and summon up th discipline to follow his not-too-complicated Rx. It helps! I may later be able to say the type II I struggle with is gone. For the moment, I can say without hesitation, my blood sugar is considerably lower in the morning, which has been a constant problem for me. His clear, uncomplicated recommendations require commitment to a pattern of eating that can drastically reduce the presence of high glucose in one's blood, help reduce weight, and help bring about a certain amount of personal peace.
My opinion is that all plans to 'self treat' diabetes should be shared with one's doctor.
