She’s ready to get fit! Chrissy Metz is excited to slim down for her role on This Is Us, but clarified that weight loss isn’t mandated for the hit freshman drama during an appearance on The Ellen DeGeneres Show on Thursday, December 1.

The 37-year-old actress plays Kate, a woman who struggles with her weight and attends Overeaters Anonymous meetings, on the NBC drama. “Like most actors, we are chameleons,” Metz explained. “We play different roles — like Christian Bale lost all that weight for The Machinist.”

Metz previously said that she was contractually obligated to shed the pounds, but explained to host Ellen DeGeneres that it’s actually something she wants to do. “I was kind of like, 'I hope I get to lose weight.' That’s a win-win for me — motivated in a different way this time,” she said. “It wasn’t mandated. It wasn’t like, ‘You have to do this.’ But if this is the story line, naturally you would lose weight. So I’m excited if that should happen.”

When DeGeneres, 58, asked Metz about a recent episode where Kate decides to get gastric bypass surgery, the American Horror Story: Freak Show actress stayed mum about how that would play out in real life. “It is a fast fix, and it’s not always the right answer,” she said of the procedure. “I can’t give it away too much.”

Metz continued, “I think with the character, Kate, she wants a quick fix because it’s not about the food. Food is the symptom. We’ll get to see all the details.”

As previously reported, last month the actress told TVLine, “In our contract, it did state that that would be a part of it, to lose the weight in the trajectory of the character as she comes to find herself,” she said. “I, as Chrissy, want to do things that mentally, emotionally and physically make me the best that I can be. That’s the intention for our writers and the development of the character."

This Is Us airs on NBC Tuesdays at 9 p.m. ET.
