Matthew McConaughey, Charlize Theron and Jake Gyllenhaal have all gone to dramatic lengths to put on or lose weight for a movie role. An expert reveals how that can be dangerous.
On the other end of the spectrum, Natalie Portman and her "Black Swan" co-star Mila Kunis revealed that they were "barely eating" while filming in 2010. Janelle Ash is an entertainment writer for Fox News Digital.
Dr. Michael Fiez, a practitioner of bariatric medicine, shared with Fox News Digital that it is unhealthy for anyone, even Hollywood’s finest, to go to such extremes to achieve a specific physique or figure.
"It is not safe for anyone, including celebrities, to go to extremes to achieve a certain body. We know that many celebrities feel the need to do so in preparation for a role," Fiez said.
