The Story of 21-year-old Lizzie Velasquez

It's an incredible story about a girl who has to eat 60 meals a day. Lizzie Velasquez is 21 and she lives in Texas. Doctors are still puzzled with her conditions. Her height is 5ft 2in (1.58m), but she weighs only 56 pounds (25 kg).
She must eat 60 small meals a day, every 15-20 minutes (5000-8000 calories) and she still has almost 0% body fat. Lizzie says that she gets very excited if she gains even one pound. She has a brother Chris and a sister Marina, and both of them are normal. Lizzie was born four weeks prematurely - weighing just 2lb 10oz (1.2 kg). Her parents say that they had to buy dols' clothes for Lizzie because baby clothes were too big.
