1. Holly Madison.

The Girl Next Door actress decided to follow a simple and effective weight loss plan based on exercise and a healthy diet to get rid of the 19 pounds that she somehow managed to put on in one year and a half. Her success story revolved around many hours spent at the gym going yoga and Pilates, and a low-carb diet that is replicated in many ways by most Hollywood A-listers who feel the need to shed a few pounds, and get in the best shape of their lives fast.

Manson got back her envy-generating curbs by replacing her beloved bagels with fruits and protein bars. The sugar she gets from fresh, organic fruits enables her to keep her cravings in check. Also, the Peepshow star ditched fast food in favor of healthier and dare we say, equally tasty snacks and foods, such as chicken and avocado. To take her healthy weight loss plan one step closer to success, Holly used weight loss supplements to boost her energy during the entire day, and suppress her appetite.
