Blue - no I am not really sure of anything, but maybe we can work through this. The reason Blood Glucose levels raise and stay that way is because there is not enough insulin to bring them down, ie low insulin. In a non-diabetic when blood glucose levels go up after eating or excersising then insulin is released but since natural insulin only has a half life of 8 minutes its gone quickly and lipolysis can start and fat burning will start as the level decreases. I think the problem with injected insulin is the half life time, its got to be over 2 hours. So when we put a heavy demand on our bodies from weights our muscles become more sensitive to insulin and the muscles take up the sugar quickly and he Blood glucose levels drop leaving us in a hypo state or high insulin which switches off lipolysis. Next time I meet with my Endo I will ask her but that is not until the end of May. In the mean time I will use Google to see if I can find out some info. What I am suggesting however is to start the workout with slightly higher blood glucose levels so when it drops you will not be hypo but will not be so low that lipolysis shuts off. Heck it might not even be possible since you would have to know exactly what level all this stuff happens. One more consideration, the reason we are told not to excersise with higher BG is so we don't go into Ketosis when we burn to much fat. I personally check my BG about three times during my workouts, my workouts are generally 60 min (I am doing P90X). Once at the start to make sure they are at a safe level, once about 30 min into it to make sure they have not dropped to far and one at the end before I take the Post workout shake. Often I find the middle one my sugars are low dropping from 6mmol to around 2.9mmol. Then I need to take some sugar stuff to keep them up.
Diabetes really is a journey.
