Meghan Trainor has revealed the anguish she felt as the trolls piled on about her recent weight loss.

The All About That Bass singer told Extra TV that the level of hate had taken her by surprise.

"I started posting pictures of myself recently, just like how I always did, but for some reason, a flame went off, and everyone got mad," she shared.

"Like, 'Don't recognise you, you're just a walking nose.' Crazy stuff. Mean. And I was like, 'This doesn't affect me.'

"Yes, it did. I cried so much. They got to me."

Trainor went on to explain that she'd talked to her therapist about how bad she was feeling, and was told that she was giving the haters "a lot of power".

"Yeah, I wish I didn't. I'm trying to learn at 31 how to not give strangers power. It all feels a bit silly."

Trainor has been open about her weight loss journey to date, which includes lifestyle changes such as working with a dietitian and using the weight-loss medication Mounjaro as a support for her transformation. But the comments have continued.

"It's crazy. I had someone come up to me the other day, didn't say 'Hi' or 'Nice to meet you', just, 'Yo, I saw a video of you earlier, and you, like, shed all this weight.'

"I don't know what's going on."
