Hi! My blood sugar levels did drop with fasting. There were times towards the end that I got a little worried with how much they dropped. With keto they dropped too. But it was a gradual drop and didn't drop 50 points in a day or 2. It took time.
Type 1 is different then type 2. You can be totally healthy and have zero other problems and get type 1. Where as type 2 is caused from being over weight or even from other diseases. I have type 2. So it's easier to change that or reverse it with diet. Type 1 is harder. I really do think that if you heal your body that you can reverse it. But I think you have to find the root of the problem. With him having type 1, I would consult with his doctor about keto and find out what they are comfortable with. I would also write everything down and keep good records. Also, go with your mom gut. The Father has put that instinct in us for a reason. ❤️ We will be praying for complete healing.
As far as OMAD....try it again for yourself. It's hard to get past the hunger pains, but you can do it. Pray and ask for guidance and strength. Remember that your body is either storing fat or burning fat.
Hope this helps!!
