The Type 2 game has already been changed with low carb/keto time restricted eating and weekly fasting of 24-48 hours duration.
I belong to a couple of fasting groups and they are filled with people who have reversed Type 2 and are off metformin or insulin.
My wife has only recently been able to go an entire day without eating, under keto/low carb. We’ve been doing keto/low carb, but she still had to eat three meals a day, or she got headaches. Her headaches from lack of eating had always occurred, since she was a child.
