Meet The Brazilian Boy Who Weighs 154 Pounds

A young Brazilian boy, who was born a healthy 6lb, 6oz, has now ballooned up to an alarming 154lb at the young age of three.

Doctors believe the boy, Misael, may be suffering from Prader-Willi Syndrome (PWS). This rare genetic condition is characterized by a constant hunger and desire to eat, which can lead to not only dangerous weight gain but also to learning difficulties and reduced muscle tone.
