Diabetic Diary is a personal journal by an ordinary type 2 diabetic. The author had been diagnosed and treated for 8 years with insulin. She had not achieved improvements in blood sugar levels until she introduced her own charting challenge. The detailed challenge diet, tests and results are reported in the book for the benefit of the reader. In 30 days the author had quit insulin and had adjusted her diet contrary to recommendations by diabetic authorities. In 60 days she had lost 16 pounds. She continues to benefit based on the results of the challenge.
