Part 13: The Beer Diet

Many people choose to give up drinking beer for Lent, a little sacrifice to hopefully better themselves for the Easter season.

This isn't something thought up during a 3 a.m. chat between two wasted frat brothers, but in fact goes far back 300 years when Bavarian monks would brew strong beer and give up on solid foods. Many people have done this fast since, included an editor of a German newspaper and an Iowa beer blogger.

The Iowa blogger says he lost 22 pounds during Lent.
