Sasha Pieterse : Dancing
Pretty Little Liar’s Sasha Pieterse had gained 70 pounds in 24 months and it wasn’t because she was doing anything differently with respect to diet or exercise. The actresses’ substantial weight gain was because she has a fairly common hormone disorder, Polycystic Ovarian Syndrome or PCOS.
Sasha later signed on to participate in the reality dance-based TV competition Dancing with the Stars. She may have gotten eliminated from the show and didn’t end up winning, but she did drop 37 pounds because of the hectic dance routines with her partner.
