The singer smiled like a box of Lizzo, which was labeled a diet suppressant and contained a fake US Food and Drug Administration approval. The costume also included a yellow measuring tape wrapped around her waist.

“Ok Halloween…you can start now,” she captioned the post with the winking emoji.

Lizzo told The New York Times earlier this year that she was on a “natural weight loss journey” that resulted in her “being methodical and losing weight very slowly.”

In September, the singer hit back at rumors that she had taken a weight-loss drug during her health journey.

“When you finally get Ozempic accusations after 5 months of strength training and a calorie deficit,” Lizzo wrote over a short selfie video.

Over the years, Lizzo has shared insight into her weight loss experiences, from exercises to recipes. Although she is celebrated for her promotion of body positivity, she is outspoken about the reality of exercise in today's world.

“The idea of ​​body positivity has moved away from the antiquated mainstream concept. It’s evolved into body neutrality,” Lizzo told The New York Times.

“I'm not going to lie and say every day that I love my body,” she continued. “The bottom line is that the way you feel about your body changes every day. There are days when I adore my body and others when I don't feel completely positive.”
