OK, that might sound like a stupid question, but I am serious. After watching my son's insulin needs change over the past few years (often by the day) depending on his level of activity, I am starting to wonder what this all means for someone without diabetes who is trying to lose weight. With Matt, his insulin needs are lowest during football season, even though that isn't necessarily the season when he is the most active. I would figure that summer would be his most active time since he is swimming on most days and generally active with friends (aside from those marathon times when he is playing video games at the end of the day, lol). I find he burns the most carbs when... 1) he does stop/start sports like football, particularly when he is sweating a lot (which he does due to tall that equipment) 2) he is active multiple times per day No matter how short the periods, if he builds up a sweat 3 times in a day, we will have to be running a temp basal and feeding him carbs all night. It seems as though, given the same intensity of each minute spent exercising, he would burn more carbs by exercising 2 times a day for 30 minutes each than 1 time for an hour. In fact, 2 play periods of 30 minutes seems to have a greater impact than 1 play period of 2 hours. A light, but steady day of exercise (such as walking around Disney all day) doesn't seem to have the effect on his insulin needs than I thought it would have. Of course, I have started wondering how this would apply to an adult trying to lose weight. I am thinking that one or two short periods of vigorous exercise might be better than 1 longer period of light/average cardio (walking, jogging, elliptical). Thoughts?
