Hi and Welcome to the Forum.
I've been where you are nutritionally speaking. I've bought so many books on diet and nutrition I could probably start my own bookstore.
We all have to find what works for us, and if you want to eat just fruit, who am I to tell you no?
I will tell you this though: You will change your mind again and again and probably just come back to McDougalling eventually.
You still seem to be searching and we all have to find what works for us and just do it.
I tried the raw thing and I just really missed my excellent hot soups, lentil loaves and other great things I create. I like raw foods and cooked foods. With the McDougall plan, you have so many choices. With the Fruitarian plan, you just have fruit. Plus those yummy greens. Although fruit is delicious and nutritious, you will get tired of it after awhile and yearn for something more. Good luck whatever you decide. It's your life, live it the way you want.
