9. Kirstie Alley
Kirstie Alley has experienced extreme weight loss and gain and loss and gain… but we hope she will soon be a weight loss success story for good. She attributes her most recent weight gain to a severe candy and soda habit. But by owning up to her bad habits and starting the Kirstie Alley weight loss program, Organic Liason, she’s already shed 50 pounds.
10. Jason Alexander
Jason Alexander didn’t set his sights on extreme weight loss—and that may be his secret to success. The pleasantly plump actor turned to Jenny Craig to lose just 30 pounds. By slashing his daily caloric intake from 4,500 to 1,500 and adding regular workouts, he was able to drop the weight in 6 months. Don’t have 6 months?
11. Drew Carey
Fed up with being fat, The Price is Right host Drew Carey shed an astonishing 80 pounds. Despite the extreme weight loss he did it the old-fashioned-way—through diet and exercise. Drew Carey does at least 45 minutes of cardio a day and cut carbohydrates from his diet.
12. Christina Aguilera
The pop diva showed off her noticeably slimmer figure and estimated 20-pound weight loss at the season-four premiere screening of The Voice in March 2013. Aguilera whipped her body back into prime form by working out with fitness guru Tee Sorge and practicing yoga. “It’s more of a mind-body thing for her,” a source revealed to Us. “She believes in exercise that she enjoys, doing strength work as opposed to intense cardio.” She’s been working with Sorge ever since.
