Next we have the story of a Mexican man who wants to weigh 290 pounds in the next few years. He's not looking to gain wait... but to shed off hundreds of pounds to reach his goal. We bring you the story of Manuel Uribe.

Manuel Uribe is a shadow of his former self. The Mexican who held the record of world's most obese man has almost halved his huge bodyweight. He's gone from the size of a small truck weighing in at over half a ton down to 325 kilos.

That 715 pounds.

He's still the size of three well-built men combined but Uribe says his target is around 130 kilos within the next couple of years.

He's hoping to notch up another world record for losing the most weight.

[Manuel Uribe, Fat Buster]:
"I used to eat a lot of carbohydrates - pizza, junk food, hamburgers, french fries, lots of beans and rice, all food with a lot of carbohydrates. Now I know a lot more because I've been taught how much food influences your body."

Uribe, who hasn't left his reinforced bed for six years because he's so heavy, drew international interest when he pleaded for help on Mexican television.

Now he says with the help of free aid from a U.S. doctor he's eating grapefruit, fish, chicken and vegetables.

He underwent a tummy tuck in Mexico that removed some fat but has left him with massive, and permanent, swelling. As his weight goes down Uribe's hopes of leaving his bed and seeing the outside world again are going up.

A previous tour attempt failed when his bed hit an overpass.

He's hoping by 2010 he'll be back on his feet to tell the world about the benefits of healthy eating.
