In 2012, Kelly Osbourne dropped around 70 pounds and has kept it off. Doesn't she look amazing here in June 2017?
Chaz Bono started out at 250 pounds before going on a weight-loss journey. Do you know how much he lost?
After losing more than 70 pounds, Chaz Bono talked about his weight loss on an episode of "The Doctors" in 2013. He said: "I just feel much more comfortable in my skin now."
Back in 2007, "Ugly Betty" actress America Ferrera told Glamour, "I feel like I'm a regular-size person — I'm a size 6 or 8, which is totally normal." But she went on to lose a bit of weight after that…
We're not sure exactly how many pounds America Ferrera shed, but she definitely looked tighter and more toned at the 2015 Oscars. And she's only gotten healthier since: In April 2017, she completed her second triathlon! It got her in great shape for her first pregnancy, which she announced in December 2017.
