Sounds like you have done your homework, and are well on the right track. I continued with much the same plan you outline, with the exception of homemade vegetarian vegetable soup which I start to incorporate in my break the second or third day (all raw doesn't seem to work for me). I added small amounts of quality protein (chicken breast, fresh fish) the second week, and small amounts of whole grains, beans, nuts and seeds, and good oil (flax and ex virgin olive). I ate this way from my break the end of July til the holidays, when I succumbed to weird food here and there. A short cleanse post-holidays really cleared that up, and I am back on track.
The only missing ingredient in your recipe is EXERCISE. If you are serious about changing your metabolism, and being able to eat virtually what you like (of course, cleansing types like us avoid putting garbage back in!!) -- exercise is definitely the key! You do not have to go wacko to make big changes -- as little as 30 minutes brisk walking 3-5 times a week WILL change your metabolism! Add that to the cleansing/rebuilding diet you are talking about and you will see big changes.
I like to walk an hour 3-5 times a week, and do yoga 3x. Of course exercise MUST be a regular part of our plan to make lasting changes!
