Meghan Trainor is addressing comments surrounding her weight loss.

Trainor, 31, said, “I’m literally for the first time ever, after having babies, taking care of my health to the highest level and I’ve never felt better and I look incredible. I feel great,” in an interview with

published on Wednesday, Nov. 12. “And that’s when people attack me.”

The “All About That Bass” singer reiterated that she is putting her health first.

“I’m taking care of myself,” she added. “I have to find a way to not be affected by that.”

In March, she faced criticism about her weight loss, and revealed in

that she decided to take Mounjaro, the brand name for the GLP-1 injectable tirzepatide.

Later that month, at Billboard’s 2025 Women in Music Awards, she shared that she began taking the medication after welcoming her second child with her husband, actor Daryl Sabara. She added that she worked with a dietician, made lifestyle changes and has a trainer.

“I’ve been on a journey to be the healthiest, strongest version of myself for my kids and for me,” she said at the time. “Yes, I used science and support (shoutout to Mounjaro!) to help me after my 2nd pregnancy. And I’m so glad I did because I feel great.”

The Grammy winner released “Still Don’t Care,” the lead single from her upcoming albumToy With Me,on Wednesday. “My page is usually a friendly, happy, mom-loving place, but it took a dark turn,” Trainor told PEOPLE exclusively of the context of the song ahead of the album announcement.

“People started commenting about my body, saying I’m too thinand that they don’t recognize me any . And I was like, ‘Oh, I’ve just been focusing so hard on my health and my fitness that I’ve never felt better.’ So, I was confused and sad and was like, ‘Oh, it’s almost worse now.’ I don’t know what happened,” she continued.
