If you have had problems with low blood sugar in your past, as I did years ago before the surprise high blood sugar, you want to be careful about fasting with diabetes. The body prefers to be on a reliable schedule for best performance. I have read that it is good to eat an early dinner and not eat again until morning with 12 hours of fasting and it works well. Some diets recommend the afternoon snack and I find that I do better with skipping it and eating an early dinner. It helps to pay attention to your personal needs. For years I knew I needed to eat by the clock and my husband loved to eat irregularly and late at night. So we had two schedules. He is deceased.
