I don't think it's worth fighting over anyones view that eye damage may not occur, and if it does, it wasn't the carbs that did it.
Possibly we should just advise people that reducing BG rapidly isn't the best approach.
However they choose to reduce it?
As an aside, what information do you have that a reduced calorie carb based approach, like the mostly carb based shakes, makes eye damage easily happen, as opposed to a lack of carbs, which has always been promoted to reduce BG. Is there another biological route to cause damage that you have information about, as It's not a view I've seen anywhere before?
