Holly Lindley, Girl With Glycogen Storage Disease, Drinks 6 Pints Of Milk A Day

Caters News

This 9-year-old girl has a serious metabolic disorder, and she's really milking it up.

Holly Lindley drinks 6 pints of milk -- each one mixed with 5 tablespoons of cornstarch -- every day in order to stay alive, the Daily Mail reports.

The English girl suffers from glycogen storage disease, an inherited metabolic disorder. There are eleven known types of GSD, but in Lindley's case, the disorder prevents her from being able to use stored glucose as a form of energy, meaning that she must consume the simple sugar at frequent intervals.

'It would be easy if she drank fizzy drinks that are loaded with sugar," her mother, Karen Lindley, told the Daily Mail, "but she doesn't like them so milk it is. We get through so much in this house."

In addition to drinking the milk and cornstarch mixtures -- which her friends call "Holly's special milk" -- throughout the day, the girl also regularly snacks on chocolate and other sweets.

"I'm sure she's the only girl at school that gets two chocolate bars in her lunch box," her mother said.

Holly Lindley isn't the only person with strange eating habits. Marla Lopez says she's gone over 50 years sustaining herself solely on white bread, potatoes and milk.

And last February, 21-year-old Kerry Trebilcock, who suffers from pica, revealed that she has eaten 4,000 sponges and over 100 bars of soap over the past few years.

CORRECTION: A previous version of this article incorrectly stated that Holly Lindley drank milk mixed with cornflour. She drinks milk mixed with cornstarch.
