The alternate phase 1 for diabetics plan is not new, it's been around a while.
If you want to do either the regular or alternative phase 1 using store bought items (alternative items) you can check out some of the threads here.
I used a lot of items from Nashuanurtition.com and also some store bought items. It was about 1/3 the cost of the IP products. I still used the actual IP supplements though as I thought they were a good quality and worth the money.
