The “This Is Us” alum, 45, said she finally came to the decision after years of ineffective.

“I’m not getting any younger,” Metz told People in an interview published Monday. “I’m in perimenopause, and there were obesity issues within my family and with my father, and I felt like I’ve tried so many modalities, whether it was diets or therapy, and none of it really worked for me.”

The actress — who’s partnered with Ro, a direct-to-patient digital health company that provides GLP-1s — didn’t share when she started taking weight-loss medication or which specific kind she’s on. But she called her experience with the medication “great” so far after being skeptical.

“It’s so nice not to be obsessing about what I’m going to have every minute, even as I’m still consuming the meal,” she explained. “I just vilified food for so long because I was taught that it was bad, and you shouldn’t eat this or that.”

She acknowledged that “judgy” people will have a lot to say about her decision, but she isn’t giving them attention.

“It doesn’t matter, because like I always say, they’re not in my life,” she explained. “They’re not in my doctor’s notes. They’re not in the hereditary issues my family has.”
