"You should try a juice cleanse!"
Fasting is something that is largely popular in religious circles because the discomfort caused by a lack of food forces one's mind out of routine, and into a space wherein one can contemplate why exactly one is going through such a sacrifice. This is ideal for meditation, or contemplating larger spiritual issues, but hey, why not harness that same spiritual energy because you're worried that your ass looks chunky in shorts? There's a New York City-based cleansing company that advertises a "platinum plan," providing 36 days of juice fasting. The same company recommends that entire bridal parties do a 3-6 day cleanse before a wedding. I've known people who have done juice cleanses and they are the exact kind of people who, if they weren't talking to you about juice cleanses, would be talking your ear off about pilot season.
