I’m really not sure that P90x or intense exercise will be as much of a problem as you think. Although I’m not diagnosed as a T1, my experience is that intense exercise, particularly anaerobic causes a blood sugar rise. When I weight lift, I’ll usually have a rise over 100 mg/dl as opposed to aerobic exercise which just depletes my glucose stores. Dr. B suggests that during aerobic exercise you consume only enough dietary glucose to fuel the workout, with something like smarties. I would not be surprised if your real challenge is your post workout levels. Although Sheri Colberg’s a good resource, she does not have much advice for the low carb athlete. In any case, everyone reacts individually, you probably should test often and be alert as you start the program.
