Dr Newburg uses a high fat diet to treat diabetes
The Use of a High Fat Diet in the Treatment of Diabetes Mellitus - Second Paper: Blood Sugar
"We reported briefly the results of an investigation of the effect of a diet whose energy came largely from fat, to which was added sufficient protein to maintain nitrogen balance and the minimal carbohydrate necessitated in making up a diet that a human being can eat over a long period of time. It was shown that with such a diet, glycosuria was avoided in severe diabetics, and that acidosis was not produced. The twenty-eight cases contained in Table 1 show that a high fat diet such as we have used is capable of bringing the blood sugar down to normal and keeping it at that level during the period of observation."
