Carnie Wilson's weight problems were always obvious. Whereas her skinny bandmates Wendy Wilson (her younger sister) and Chynna Phillips were shown wearing short black dresses in their 1990 music video "Hold On," Carnie was hidden behind a jacket. (Allegedly her weight peaked at 300 pounds during her Wilson Phillips days.) Her 1999 gastric bypass surgery was broadcast live on the Internet, and she went from a size 28 to a size 6, even posing nude for "Playboy" in 2003.
