Yeah, the diet is important, but you can tweak it a bit so it's more doable. They don't advice any juices and want you to eat cooked vegetables three times a day. I cook a shit load of vegetables each morning and add them with organic tomato, carrot and/or beet juice. I drink this throughout the day and try to mix the vegetables as much as possible. It's not even that bad. Brown rice for carbs. Lots of eggs, meat, chicken and fish. Limit sugar and grains as much as possible, drink four glasses of hydrogen water and you have a very strict, but doable diet you can follow for months. My only fault is that I eat two low sugar/low carb protein bars each day, but that's something I can live with when I decide to call it quits at the end of the day.
