Well, type 2s on diet only don't really have to worry about hypos so eating no carbs means that BG levels are low without having to worry about it going too low. Plenty of fat around the middle for my body to convert. I do eat carbs though, I just stick to complex carbs and try to be careful about the amount I eat.
Injuries are a pain, if you'll forgive the pun. I have osteoarthritis which limits walking so I row and cycle on an exercise bike. That can hurt my back which is weak and when that goes, which it occasionally does, I'm useless for a week or so. I got some high rise handlebars for the bike which help a lot but otherwise yes, I agree, you are constantly chasing problems and, whatever solution you come up with, there's another, new, resultant problem. Still, we don't have poisonous insects and snakes, animals that see you as food, we don't get major earthquakes or tsunamis and there's little danger from volcanos and hurricanes, so life in the low carb lane seems a little dull really. I won't complain if I die bored, excitement is overated.
