Not the exact question, but just learned this... I just started some strength training on a resistance system a few nights a week, and I have found that I get a little light headed if I go into that on an empty stomach. I thought it was a fluke the last time, but it happened again tonight. So, I'm going to eat a little before that next time and see what happens. I don't get hungry or light headed at all during the cardio in the AM, even when I work myself much harder than I probably should...
