Al Roker

The Today show’s weather anchor also turned to surgery to get trim. Roker, 56, weighed over 340 pounds in 2002 and was wearing a size 60 suit.

His weight had fluctuated throughout his life, but he had always gained the 30- or 40-pound losses back. In 2002, he underwent gastric bypass surgery at his wife's suggestion and dropped 140 pounds. He says that he has finally accepted that maintaining a healthy weight will be a lifelong battle even after surgery. Today, he watches his portion sizes and exercises regularly to stay around 200 pounds.
