One easy way to get started on this which isn't an extended fast is to do something like the Warrior Diet. What I do is skip breakfast and lunch virtually every day, except for fresh vegetable juice I make myself, and all the coffee and water I want. Occasionally I have one or two dates or a banana, if I really need something. Then I eat a big dinner, ideally balanced with vegetables, meat and carbs at the end--but usually it's not the ideal. Eating dinner is really enjoyable, and there's no guilt.

I started this just over a month ago and have lost ~15 pounds so far (from 240 to 225, I'm 6'3"). I've never felt better. The juice I make is: 5 lbs carrots, 4 red beets, 1 kale, fresh ginger root, fresh turmeric root. All organic. It lasts 3 days, which is good since cleaning a juicer is annoying. I bought the "Tribest GSE-5000Green Star Elite Jumbo Twin Gear Juice Extractor" from Amazon.

Ironically, I started this during a 1-week vacation at an all-inclusive resort. I'd never been to one before, and by the second day I resented being told when to eat enough that it seemed the perfect time to try something like this...
