When I first was diagnosed with Diabetes I was told that I can’t fast as I have to make sure to keep my blood sugar level. That along with other things that only increased my blood sugar level. I no longer follow those rules.
I am now on the keto low carb high fat way of eating. It is not a diet for me, it is the way I will eat for the rest of my life. That means I limit carbs to 20g or less of carbs a day and practice intermittent fasting.
I eat my breakfast around 7:30 am and my supper at 5:30 pm and for the inbetween time I only drink water. That gives me a 10 hour eating window and a 14 hour fasting window.
