Lizzie Velasquez must eat every 15 minutes to stay alive.
The 21 year old Austin TX native has to consume 5,000 to 8,000 calories every day in order to keep from losing weight. She has to wear size triple zero clothes! She says she used to wear doll clothes as a baby, because she was born premature, at only 2 pounds, 10 ounces. She has zero percent body fat, and she is blind in one eye.
Doctors say she has neonatal progeroid syndrome, which causes fat loss in the face and accelerated aging. There is still not much known about her condition. Despite her condition, Lizzie has been able to do a lot of things. She has been a cheerleader in high school. She also runs her own website, she works as a motivational speaker, and she writes books!
