I had the cyst for many years before it was discovered, and even now, it is not growing and is only 2cm in size. It is surely not the reason for weight loss.
But fasting is. Fasting may have made me worse off.
I know all about weight lifting, but isn't Creatine a terrible thing for someone with kidney problems...
At any rate, it seems like a lot of trouble just to get back to where I was before the fast.
