la de da, until your body switches over to a new fuel for energy...Lets not start another debate in a thread that was meant for a quick answer. Ive ran the diet, Im running the diet, and after those first few days, and you start using other sources for energy, you feel like you have more energy than you did before and I feel more focused. Blah, there is really no reason for any more posts in this thread, the issue has ben resolved lol...I dont want a low carb vs whatever, battle in here.
