World's Fattest Man Prepares For Life Saving Surgery After Spending 7 Years Confined To A Bed (Photo)

The world's fattest man is preparing for life-saving gastric bypass surgery after spending nearly seven years confined to a bed. Juan Pedro Franco, who once weighed more than half a ton, has lost a whopping 27 and a half stone to go under the knife.

The 32-year-old, from Aguascalientes in Mexico, has been on a three-month diet to prepare for the operation on Tuesday.

He will go through a series of intense tests, with his blood, imaging, pulmonary and cardiac function studied by a team of doctors.

Doctors hope the surgery will help Juan walk again - after being confined to his bed for nearly seven years.
