That site looks awfully prescriptive to me, placing a lot of emphasis on weight loss yet lacking consideration for factors such as underlying insulin resistance. I know I wouldn't be able to follow such a specific meal plan without understanding more about the specific justification for what I was being directed to eat. What if I felt like something different on any given day?

I'd probably prefer something that still sets some boundaries, but offers me more flexibility within those boundaries. Sites like Diet Doctor are much better in this regard, I think.
