Creatine
I've been losing weight (fat) these past 3 months at a 2-3lbs per week pace. Each night before bed I will dip into the protein powder for recovery and blood sugar stabilization....good stuff. So when I ran out of Whey Isolate I grabbed for my winter weightlifting blend with Creatine. I know better than to do this but hey, what's 3 nights going to do? There was that familiar craving of water one evening that led me to immediately stop and vow to throw the stuff away.
I had gained 4lbs in 48hrs. Now, let's see how long before I beat a trail to the bathroom to get rid of it. On the good side, my 30mi ride was almost 20min faster than any previous on that route. A huge improvement and was coming down the homestretch at 22mph which never happens.
