I've not used the program, but I did just read a little about it and it seems well structured. I wish you continued success!
I commend you for wanting to stay off the scale, many a successful program has been derailed by the weight monitoring efforts of dieters. It's usually important to remember that what we are REALLY after here is likely a particular body composition, not a particular weight. If you could look exactly the way you wanted, but at your current weight, OR look exactly the way you do now, but at your desired weight, which would you choose?
It's great that you're feeling better and have energy, are you coupling the diet with a particular exercise routine? What does a typical day's menu look like?
I am sorry for the questions, I'm a personal trainer by day and really love collecting info on what works and what doesn't. Thankfully, it sounds like you've found something that works!
