Eating a solution diet as a way to maintain your diabetes is literally no different than what a diabetic normally does. Insulin makes this easier, but you do not HAVE to take insulin if you are a diabetic.
If diabetes was cured, then the diabetic would be able to eat a bucket of ice cream every so often. It's like telling a person with erectile disfunction that the way to cure their wang problem is to just not use it. It's the same thing, except replace erectile disfunction with diabetes, and replace wang with pancreas.
If anything, I'm not getting the impression that this is a cure for diabetes, I get the impression that it is a way to make yourself more independent from the pharmaceutical system.
There is a difference.
Not trying to slam anyone to the ground here either, but the information that Bjra is giving here is very misleading, and I think it wouldn't do any harm to look at it in another way.
