Lizzie Velasquez weighs just four stone and has almost zero per cent body fat but she is not anorexic.
In fact, the 21-year-old from Austin, Texas, must eat every 15 minutes to stay healthy.
Miss Velasquez has a rare condition which prevents her from gaining weight even though she eats up to 60 small meals a day.
Despite consuming between 5,000 and 8,000 calories daily, the communications student, has never tipped over 4st 3lbs.
I weigh myself regularly and if I gain even one pound I get really excited, said 5ft 2 ins Miss Velasquez, who wears size triple zero clothes.
I eat every 15-20 minutes to keep my energy levels up.
I eat small portions of crisps, sweets, chocolate, pizza, chicken, cake, doughnuts, ice cream, noodles and pop tarts all day long, so I get pretty upset when people accuse me of being anorexic.
She was taken to see genetic experts but they still could not diagnose her.
Miss Velasquez's case has fascinated doctors all over the world and she is part of a genetic study run by Professor Abhimanyu Garg, MD, at the University of Texas Southwestern Medical Center in Dallas.
Professor Garg and his team now believe Lizzie may have a form of Neonatal Progeroid Syndrome (NPS) which causes accelerated ageing, fat loss from the face and body, and tissue degeneration. People with PRS often have triangular and prematurely aged faces with a pointy nose.
