Jessica Leonard, 5 year old girl weighed 230lbs (140Kg). According to an article in Woman’s Day magazine by Graeme Culliford V (reposted on Bodybuilding forums) Jessica’s weight problem had become life-threatening, made her unable to walk, and caused severe respiratory and circulatory issues.
In October of 2005, a stranger had called Children’s Services to report their concern for Jessica’s well-being, prompting a 19 month stay at a specialized obesity clinic in Virgina, where the eight year old successfully got her weight back down to 110 lbs. Diet and exercise are credited as being the method of weight loss, although she has undergone other surgeries to correct other related issues such as excess skin and bowed legs.
By the time Jessica was 7 years old, she weighed in at 400lbs. Since that time, Jessica has apparently received medical attention with a focus on increasing energy expenditure, a strict diet, and prescription of some undisclosed medication. Miraculously, as the next video shows she has lost a tremendous amount of weight.
