Prior to the advent of insulin, in the 1920's, diabetes was treated with a low-carbohydrate diet. These diets were aimed at controlling sugar in the urine, a stark contrast to the current ADA suggested diet of low-fat and high-carbohydrate. In fact the diet recommended by Dr. Elliot Joslin consisted of approximately 20% protein, 75% fat and 5% from carbohydrates.
Well in the early century - this diet seemed to hold most diabetics on course just fine without the magic pills available today. It is also remarkable that the secondary complications and epidemic growth of diabetes was not a hot topic, either. Researchers decided to give Dr. Joslin's diet another go in a modern environment. The results of this low-carbohydrate ketogenic diet (LCKD) improved glycemic control in patients with type 2 diabetes such that diabetes medications were discontinued or reduced in most participants - 17 out of 21 completing the study. The original study had 28 participants, with 8 dropouts. The LCKD can be very effective at lowering blood glucose. Participants also experienced reductions in body weight, waist circumference, and body fat.
It's funny how this study, conducted in 2005, produced results seen almost 100 years prior. LCKD appears to be a reasonable cure for type 2 diabetes. If most diabetes was adequately treated back in days of 1923 without the assistance of pills and insulin - why is it such a mess nowadays? Where did we go wrong?
Now that the US market is suspiciously saturated with human insulin - and many of us diagnosed within the last 10 years did not have a shot at trying porcine insulin - I'd like to set the record straight. When the pharmaceutical companies cherry pick the studies they wish to use for their gain, and not so much for your enhanced quality of life - they must've lost
