We all know that Charlize Theron is one of the most talented actresses in the industry. We also know that she’s no stranger to transforming her body for a movie role. She did it for 2003’s Monster (she won an Oscar for that performance, NBD) and now she’s done the same for her upcoming film, Tully. In a recent interview, Theron revealed that she gained 50 pounds for the role, and though she’s since lost the weight, she acknowledged it wasn’t a fun or easy process.

The 42-year-old opened up about her emotional weight loss journey to Entertainment Tonight on Tuesday, April 17th.

Theron also noted that a big part of the struggle was accepting that her body at 42 is different than it was when she was in her 20s, and that means her weight-loss journey was also different.

Though she admits it was “hell,” she ultimately gained (and lost) the weight for a performance Variety calls “fearless, emotionally raw, and physically intense.

We applaud Theron for being so open and honest about her difficult body transformation. We have a feeling so many women will relate — and will feel so much better about their own body trials and tribulations knowing that everyone, even Hollywood actresses, go through it, too.
