This is an incredible 6 week system that transformed me. The only thing to note is that at first you will gain weight because your muscle is developing and you will look bigger because the muscle is pushing out fat that hasn't burned off yet. About 4 weeks in I noticed I could pretty much eat whatever I wanted. The only downside is that the video that you do the longest (~4 weeks) takes 55 minutes....in addition to the shower you MUST HAVE.
