Hi @cpd54, I don't think fasting cures anything but I do believe it can help with autoimmune conditions. I've always been in the pre-diabetes category and needed to lose some weight and the only way I've found to maintain my weight loss is using intermittent fasting along with lowering the amount of carbs I eat. It sounds like you also might fit in the metabolic syndrome category being prediabetes. We also have a discussion group on Connect for low carb healthy fat (LCHF)

Dr. Jason Fung has some YouTube videos that provide more information on how fasting helps the autoimmune system. Here are a few:

I switch up my fasting to fit my schedule with family plans but normally use a 18/6 or 20/4 (18 or 20 hour fasting period with 6 or 4 hour eating window). I use the free Zero app (https://zerolongevity.com/) on my phone to keep track which makes it easy to follow. When I started intermittent fasting the nighttime cravings were my biggest issue and I was mostly doing the 16/8 fasting plan. Gradually the snacking and craving goes away and it's easier to fast for 20 to 24 hours. I definitely feel better and my A1C has improved.

Have you done any research or reading on intermittent fasting?
