DeletedUser127 Sadly there are actual type1 people out there who's life is a lot simpler with GCMs. You're right with your statements, but still, a GCM is very good to have.
You can totally reverse type2, but I never saw anything good happen to type1 people on keto. Most had severe issues with dangerously low sugar levels
Also, as a keto guy myself, using a GCM from time to time is quite nice, as you can see how certain foods impact your glucose levels. My levels are mostly one straight line, and it's cool to see which foods disturb the glucose levels, so I can avoid them in the future
