Master Cleanse

Celebrities like Beyoncé have been known to try this liquid and laxative diet to drop pounds quickly. Essentially a 14-day fast that involves a diet of fresh lemon juice, maple syrup, cayenne, and water (plus a laxative in the morning and at night), it is meant as a juice detox diet and has spurred other less-intensive juice diets like the BluePrint Cleanse. If you do try this, be careful the first day and make sure you stay close to a bathroom (there are some not-so-great stories out there).
