Michael there is huge help out there for type 2 diabetes. It is now treatable. Not all doctors are aware of the ketogenic diet, which, if followed well, can reverse diabetes. It is not the life sentence it once was but you have to want to reverse it.

I suggest to start with, you read as much of the Diet Doctor website (Swedish doctors) and then follow through with Dr Jason Fung. He's a Canadian nephrologist and has written some of the best literature on diabetes.

Read cases studies

Go with your FIL to the doctor with questions. Don't leave it to him.

In my opinion these are your best chances...maybe ditch the cake too!

I included a link to intermittent fasting as well.
