Maria Menounos has a smoking hot body! But it wasn't always like that.
The TV host recently opened up about her struggle with weight when she was a teenager.
"In my freshman year of high school I was a size 3, and I grew a size every year," Menounos said, adding that "it got worse in college." "I didn't gain the Freshman 15—I gained the Freshman 40," she admitted.
In her 20s, the now 35-year-old decided to make a change and get healthy. "Since I couldn't find a plan that worked for me, I decided to create my own," she said. "Within a year I lost 40 pounds."
But Menounos isn't the only star with an inspiring journey of weight loss and health. Here are five other celebs with dramatic weight loss stories.
1. Tom Arnold: Just last week, the 55-year-old funnyman debuted an 89-pound weight loss at the 2014 SXSW Festival in Austin! The now-slender star, who weighed 287 at his heaviest, cited the recent birth of his son, Jax, as his motivation to get healthy through diet and exercise twice a day.
2. Rachel Frederickson: The Biggest Loser season 15 winner shocked viewers when she showed off her unbelievably skinny figure on the finale episode. Frederickson took home the $250,000 prize after losing 155 pounds! She lost over half her body weight, going from 260 to 105.
3. Jennifer Hudson: Between 2010 and 2011, the former American Idol castoff turned Oscar winner lost 80 pounds with the help of Weight Watchers. She went from a size 16 to a 6 and has successfully kept the weight off for over three years.
4. Christina Aguilera: Back during the 2012 American Music Awards, Xtina covered up her curves in a floor length dress. Flash-forward one year, and the singer looked super-svelt! A source told E! News of her healthy approach to gradually losing weight, "[She's] making herself a priority, trying new exercises and trying things she loves and enjoys rather than stuff to just 'lose weight.' This is really from the inside out."
