Dr Jason Fung who’s a nephrologist is a big proponent of fasting to treat his diabetic patients. It’s hard to fast at first. Juicing puts the foot in the door. It gives you your daily intake of the super nutrients provided by fruits and vegetables. This takes the edge off when you fast. Give it a three day detox followed by a one week juice only fast. At my age it went pretty fast. Expect misery through the detox. Take plenty of showers and you might as well stay in bed. Juice when you feel like you're hungry. You will probably have to adjust intake depending on your individual needs. Most importantly inform your healthcare provider to assist. If they won’t then find someone who will. At first I was juicing 3 times a day. Earlier the next day. Kinda stepped it up some. Found out what I liked or hated. Combining different stuff. Kinda like cold cooking. I wouldn't say it was fun but really easily tolerable. Towards the end of the 10 days I was naturally deceasing the times to two per day. I was also shrinking my window until it was a four hour window. After the 10 days is over the second juice was replaced with a low carb, high protein meal that I ate only to satiation. It’s been 20 days and I’ve dropped 24 lbs. My longest fast was 38 hours. I now find it easy to fast for 20 hours. I started this because of my insulin resistance.
