Hmm. Interesting. It is clearly aimed at lowering carbs.
But I don't think it is really aimed at diabetics (well, it certainly isn't aimed at me!). The morning exercise suggestion, on an empty stomach, would be a disaster (for me!).
My dawn phenomenon liver dump is quite large enough already, without demanding more to fuel cardio. I would crash and burn into a hypo that would taint the whole day. It is very important that I do not do much physical activity before I eat in the mornings. I've learned this from a lot of experience. A protein, low carb brekkie is best (for me!)
Also, since I'm already in ketosis a lot of the time, I would like to think that I don't have much glycogen stored (one of the reasons I crash so easily with abrupt/sustained exercise, I suspect).
So clearly I don't need to exercise!?
Yes, that WAS a joke.
