Despite what the titles of her hit singles “Confident” and “Sorry Not Sorry” might indicate, Demi Lovato struggles with body positivity like so many of her Lovatics fan base.

“It’s a daily battle. Some days I feel great and some days I don’t feel great. And sometimes it’s periods of times,” the singer, 25, tells PEOPLE. “I stopped dieting and have gained a little weight so it’s been a struggle but at the same time, I’m happier because I’m not restricting myself from certain foods and I’m no longer food shaming myself.”

Lovato, who recently launched her third capsule collaboration with Kate Hudson‘s activewear company Fabletics, told fans and social media followers in January via Twitter that she has “given up dieting and in exchange has “given up the chronic stress” of food shaming herself.

“I think that’s something in our society we get caught up in diet culture. Every commercial on TV is either about a weight loss pill or piece of fitness equipment or it’s all food-based,” says Lovato, who credits Brazilian jiu-jitsu, which she has been practicing for two years, as her go-to workout and source of empowerment.

“As someone recovering from a food disorder, it’s something that I want to put out there that you don’t have to diet in order to be happy. I don’t think I’ve heard that message out there in the public and of course, it’s important to be healthy and everything in moderation is fine,” Lovato shares.

Her tweet about no longer dieting was specifically timed, according to the Tell Me You Love Me hitmaker.

“I wanted to put that message out there for other people especially with the new year coming in because it’s very triggering for people that are in recovery because everything is about weight loss,” Lovato explains.

Adding, “Because new year’s resolutions are about going to the gym and it’s really important that there’s somebody out there to speak up and say, ‘Hey your weight doesn’t define your self-worth and it definitely doesn’t define your beauty inside and out.’ ”

After candidly discussing her eating disorder in her YouTube documentary, Simply Complicated, the Grammy nominee reveals a positive update on her recovery.

“I think every day I work towards a better version of myself. It’s recovery so I don’t think it’s something that there’s a cure or anything like that,” Lovato says. “I work towards a better life. And I’m definitely in a great place.”

Honest about body positivity and the own struggles with her eating disorder, Lovato is now embracing her curves with bikini and one-piece-clad selfies on social media.

“I think posting sexy pictures are so empowering and liberating,” she says about never hesitating to share sultry photos.

“Anytime you can put yourself out there the more empowering I feel. Also it doesn’t hurt when you look good and you have a good bathing suit on and then a cute guy likes your picture. Doesn’t hurt,” she shares.
