Meet Lizzie. She was born without adipose tissue, and can't gain weight even though she eats 60 times a day. She's never weighed more than 60 pounds.
All her life she's been bullied and ridiculed. In fact, some mean people took a video of her when she was younger and posted it on YouTube as "The World's Ugliest Woman."
Well, when you watch her video, you'll see how beautiful she really is.
