The book I read, French women don't get fat (although I won't recommend it to you for obvious reasons) recommends a weekend of what she calls "magical leek soup." Its a jump start that makes you lose like 5 pounds (but still gives you good nutrients). I'd give you the recipe, but I gave the book to my mom. I'm sure you can google it. Its basically justed boiled leeks and you drink the juice, but you can also make a soup out of it.
