Christian Bale
As a heavily decorated Hollywood actor, it is not a surprise that Christian Bale would have to adhere to weight loss programs which are pretty strict from time to time. He is celebrated for the transformation he underwent from being the starved main character in the movie The Machinist to being a superhero in Batman Begins.
Alec Baldwin
It seems like Alec Baldwin has been in the business forever. The Hollywood veteran began his journey with weigh loss programs after being diagnosed that he was prediabetic. Since then, he has dropped over 30 pounds.
