Elizabeth Anne Velásquez (/ˈlɪzi vəˈlæskɛz/; born March 13, 1989) is an American motivational speaker, activist, author, and YouTuber. She was born with an extremely rare congenital disease called Marfanoid–progeroid–lipodystrophy syndrome that, among other symptoms, prevents her from accumulating body fat and gaining weight. Her conditions resulted in bullying during her childhood. During her teenage years, she faced cyberbullying, which ultimately inspired her to take up motivational speaking.
