Rachel Frederickson – Diet & Exercise / 155 pounds
There are some reality shows which can be beneficial in some cases, and one of them is The Biggest Loser. Rachel Frederickson decided to compete against other overweight contestants but mostly compete against her own self. With a heart of a giant, she became the show’s winner, and she incredibly lost 155 pounds! However, many doctors caution against losing weight in such a brutal and quick way, as it can result in many health disorders, especially for the heart. But then that’s what the show is about – dropping pounds without any surgery.
