hi again, everyone. and thanks for your responses! i'm still getting used to this forum, so i'll do my best to respond to as many questions/points as possible (and if i forget your names, please forgive me lol).
anyways, in regard to my BG before and after exercising... while i do test myself multiple times a day (like, between 6-12 times a day, depending on how i'm feeling), and i always make sure to test myself before, during, and after exercising, the main problem i'm finding with that in preventing BG lows is factoring my present glycogen storage at the time of each workout. i learned this over the summer when i was attempting variations of diets such as atkins and south beach, and whenever i start cutting carbs and eating foods with a low GI, my glycogen stores always affect my BG differently within the first 2-3 days, and then after. the first 2 days, while i know my liver is releasing the excess glycogen it's built up from my last carb fest, my BG tends to be normal to lowish during the day (though i don't have to eat as much to raise it, since the glycogen usually kicks in not long after to raise it enough back to normal), but it's during the night of those first 2 days that my glycogen stores raise my BG significantly, so i have to give myself extra NPH before i go to bed to keep it normal by morning. so far, i haven't had almost any problems with this routine thus far.
but it's after those first 2 days that i have to start monitoring my BG a lot more closely and often, factoring in that most of my glycogen stores have been used up, so if my BG drops, there will be little my liver can do to raise it on its own. so during this time when i exercise, if i test my BG before my workout and it reads anything less than 10mmol/L, i'll have something like a cereal bar or cheese and crackers before starting. most of the time this works and i'm usually pretty accurate in figuring out how many carbs i'll need to keep my BG stable while exercising. but the longer i go from the first 2 days when i first emptied my glycogen stores (which, as i understand, is what must be done in order to get one's body into "fat burning" mode), the more erratic my BG becomes (very often resulting in lowish readings after working out, which i usually correct with another bar or something), til my readings start becoming too low after my workouts for me to raise with just one bar or whatever i carry on me (which usually leads to me going home and gorging). like i said before, this whole cycle tends to run in 1-2 week increments, and while i'm confident it would actually *work* helping me maintain a steady weight loss, the only thing that keeps setting me back is my BG dropping as more time passes since i last emptied out my glycogen stores. does what i'm describing here make sense to you guys?
also, another thing i wanted to inquire about is problem with "starvation" mode and staying adequately fueled throughout the day so i dont go into "starvation mode" and binge later. but if i'm taking in, say, 1,400-1,500 calories throughout the day, eating healthy, clean food (which very often i do), but then workout for an hour or more, burning 400 calories or more, is that still gonna put my body in starvation mode, if i'm burning past 1,200 net calories for the whole day? i've been told by other people dieting (non-diabetics, i should add) who say that as long as i'm actually eating 1,500 cals to start with, if i burn an extra 500 on top of that, it's still considered "healthy" and won't put my system into starvation mode. is this accurate? cause by now, i really don't know...
