1. Rosie O’Donnell
Rose suffered from a heart attack back in 2012, and her doctors said that if she has another attack, then it would be impossible for her to survive. To prevent that from happening the doctors suggested her to have a gastric sleeve surgery, which she got done in 2013. This surgery plays a great role in losing weight, but Rosie also maintained a healthy diet and exercise along with it. Before the surgery, she weighed 237 lbs, but now it is said that she has lost 60 pounds ever since and is continuing to lose more.
