Manuel Uribe traveled to the shore of a lake in northern Mexico without ever leaving his specially designed bed. A forklift hoisted the bed onto the truck, which then hauled him to the lake, where he snacked on fish and vegetables and joked with a local boat operator.

Looking at the boatman's small craft, Uribe joked, "Too bad I can't get on it — it would sink."

Once considered the world's fattest man when his weight hit over half a ton, more than two years of steady dieting had helped Uribe drop to about 700 pounds as of June — 550 pounds less than his former Guinness record weight of 1,235 pounds. He did not say what his current weight is.

While somewhat bothered by the summer heat, Uribe appeared to enjoy Sunday's outing. He is still unable to walk, and his last planned outing in March was aborted after the platform carrying his bed got stuck under an overpass.

His last successful trip outside his home was in March 2007, when six people pushed Uribe's wheel-equipped iron bed out to the street as a mariachi band played and a crowd gathered to greet him.

Before that, he hadn't left his home in five years.
