I knew a guy at a former job (he was an IT consultant / project manager type) who went to Eastern Europe for a consulting gig for a year.

He drank three beers a day and still managed to lose 30 lb. by walking everywhere.

A guy in this story about hiking the Appalachian Trail ate a high-fat, junk food diet and still lost 40 pounds during the hike. Lots of walking does burn the calories.
