I used the last of my alone time on the plane to finish Half Assed: A Weight Loss Memoir by Jennette Fulda. She lost 184 pounds on her own, via a healthy diet and plenty of exercise. The book had me laughing out loud on virtually every page (which probably annoyed my fellow passengers to no end). She writes the blog pastaqueen.com, but even if you read her blog, I would still highly recommend her book. It makes me want to get off the couch and go outside.
Watch as she shrinks before your eyes. (How cool is this video?)
