Probiotics - Seem to be working!

I started taking a probiotic supplement about 1-1/2" weeks ago. My wife had read a lot of articles, particularly from Dr. Oz, about the benefits. The goal is to turn you gut into a fat eating machine. Well, this past Saturday I weighed in. It was my first full week with the new supplement. I lost 5 lbs! The probiotics was the only change I had made for last week. Workout routine remained the same, food intake pretty much the same. Still too early to give a final verdict, but looking good so far. As a note, the supplement we are using is Ultimate Flora. If you have any experiences with probiotics, please share.
