I just started a low carb diet today...South Beach...doing it to support my GF who really wanted to try it. Anyway, I read that caffiene is not allowed during Phase 1 (very low carb) because it can induce an insulin spike. Any truth to this? I was planning on taking half doses of Xenedrine to help keep the energy up but don't want to undermine the whole point of low GI carb diets.
