"My Big Fat Fabulous Life" follows Whitney Thore's emotional journey after being diagnosed with polycystic ovarian syndrome. The disorder caused Whitney, a slender dancer at the time, to gain more than 200 pounds in one year at college. Feeling trapped in a big body, she struggled with self-doubt and negative stereotypes. Now 380 pounds and eager to continue sharing her passion for dance, Whitney has learned to embrace her body and love herself again. She teaches dance classes for plus-size girls, explores the dating scene, confronts bullies, and wears a bikini on the beach for the first time in 10 years. She also spearheads a campaign that fights body-shaming and promotes self-love and acceptance. To that end, Whitney Thore is no longer letting her fear of people's judgment dictate the way she lives her life.
