You gotta give the guy props for not only getting his health back, but also influencing others to do so and documenting his experience for even more to be inspired. It doesn't sound like he was motivated by either greed or fame. This work is bound to be subjective - the man's not a journalist setting out to expose the world's problems; it's a diary, examplary as it may be. Most people who 'see the light' turn into missionaries. In his case, with such a positive and undeniable message, I personally don't mind.

You know, I don't think that a specific diet, the juicer, the ingredients, etc. is what matters. We all know the solution: eat less, exercise more, and stay away from red meat, caffeine, sugar, and all the modern crap.
You could go on a water fast for a while then just eat fresh fruits and veggies - this is what I do. Even with supplements (multi-vitamins, but especially fish oil, calcium and B12), you'll be ahead in the spending department when you cut all the 'staples' like dairy, coffee, and sugar.I had let myself go a little bit and am now back in my twenties' shape at almost 50. Dropped 25 lbs (huge for me) and am trying to get under 10% body fat. All in mere weeks.
I'm a busy single guy and don't cook anything - I just grab an apple/banana/orange, whip up a salad (just lemon juice as a dressing), snack throughout the day on baby carrots and nuts, and I'm good. I only drink water and green tea. At work it's harder and just have a granola bar each time I need the energy. Expect to be hungry often (you get used to it, just like we're used to being always sleepy and overfed), but also that your stomach will shrink and you'll be easier to satisfy. I don't worry about all that fiber or the need to absorb the nutrients - the body adapts and knows what it needs. Now if you feel like preparing juices and go for elaborate tastes when you have time and money, go for it, but eating healthy is simple and cheap.
