German magazine Spiegel has a bizarre article on Lizzie Velasquez, the skinniest 21-year-old. How skinny? We're talking Egyptian-mummy-sitting-in-the-desert-for-3000-years-skinny, if the photos are any indication. Despite the fact that the girl spends her day wolfing down burgers, fries and cake, at a caloric intake more than three times the normal requirement, she is thinner than anyone thought possible: we're talking zero body fat. Nill. Nada. Doctors can't explain how she can be so underweight and still be alive.
