My first plateau

Well, it happened this week. I was wondering when I was going to hit a plateau while still following the first week exercise routine. I've lost 10 pounds so far and it's been holding at that for the last 5 or 6 days now. I had a few whole wheat pasta meals with lean ground beef during that time just to use up the penne that was sitting in the pantry. I hate penne, but my wife had bought it a while ago and I was tired of looking at it. I also had a couple of side dish servings of potato and rice this past week. But I doubt that's what is causing the plateau. It's time to up the intensity level to the week two routine. So I'll be reviewing that this weekend and starting on it. I'll keep you posted. Hopefully it'll get the metabolism fire going again. I'm not depressed or disappointed in any way though. I was curious to see how long one could go on the week one plan before hitting the plateau. For me it was about 3 weeks.
