"I would never wish these for ANYONE and I would hope we prioritize our health because we LOVE ourselves and our bodies," Michaels wrote in a statement shared on Twitter.
Michaels' troubles began Wednesday morning when "AM to DM" co-host Alex Berg brought up the fitness guru's concerns about "political correctness" in the health world. Michaels has publicly condemned fat-shaming, but has also cautioned against going too far in the opposite direction, telling Women's Health UK last year, " ... obesity in itself is not something that should be glamourised."
In Wednesday's interview, Michaels doubled down on her stance.
"We should always be inclusive, but you cannot glorify obesity. It's dangerous," she said. "Now, it's like, 'Ah that woman is 250 pounds, good for her!' ... It shouldn't be one way or the other. It's really no one's business to comment. It's not something you should judge. It's not something you should celebrate."
The conversation then turned to Lizzo when Berg mentioned how much she enjoyed seeing plus-size celebrities, such as the 31-year-old singer and model Ashley Graham, preaching body positivity and promoting their images - "bodies that we don't get to see being celebrated."
Michaels quickly interjected, cutting Berg off to ask why people don't just celebrate Lizzo's music. The singer, born Melissa Viviane Jefferson, has emerged as a vocal body positivity advocate with hit songs featuring lyrics such as, "If I'm shinin', everybody gonna shine" and "I do my hair toss/ Check my nails/ Baby how you feelin'?/ Feeling good as hell."
"I'm just being honest," Michaels said. "I love her music. My kid loves her music. But there's never a moment where I'm like, 'I'm so glad that she's overweight.'"
Michaels later added: "If you said to me, 'Hey, Lizzo can live to be 90 and motivate people or she can die at 60 and motivate people,' why wouldn't I say I hope she's as healthy as she can be? It's not about saying that I don't respect her, I don't think she's awesome. I absolutely do. But I also would hate to see her get sick."
Lizzo's supporters, however, interpreted Michaels' comments as an attempt to "fat shame" the singer, who has been candid about overcoming body image issues. Just days before Michaels' interview aired, Lizzo announced that she would be taking a break from Twitter, citing "too many trolls" as the reason for her hiatus.
"Stop concern-trolling fat people and get in the bin," actress and activist Jameela Jamil tweeted Wednesday, including an emoji of a person throwing away trash.
Several people highlighted Lizzo's high-energy performances as evidence of her health, noting that she not only sings, raps and dances but also plays the flute onstage.
"Do let us know when you can twerk and play the flute at the same time, Jillian," one person tweeted. "Until then, shut your mouth."
Critics also rushed to lambaste Michaels for her controversial career as a personal trainer, pointing to her time on The Biggest Loser, where she became known for her "tough love" motivational style. One 2016 article from the Guardian reported that "Jillian Michaels's tactics wreaked havoc on show contestants," adding that she often "verbally threatened" and "hurled insults" at participants on her team. (A reboot of The Biggest Loser is slated to premiere later this year on the USA Network. Michaels is not taking part.)
"If I had been exposed to more Lizzo and less Jillian Michaels when I was younger, maybe I wouldn't have spent half my life hating my body," one Twitter user wrote.
But others defended Michaels.
Comedian Josh Denny tweeted, "As an overweight fat person, I (100 percent) agree with @JillianMichaels about Lizzo."
"Accepting being fat is the same as accepting being poor or unsuccessful," Denny wrote. "Nobody wants it; it's a matter of how hard we want to change it. But stop disguising 'giving up' as 'acceptance.'"
Michaels' fans were equally supportive when she addressed the controversy Wednesday evening, but her statement did little to sway detractors, who demanded that she apologize to Lizzo.
"Jillian, you were on a show called 'The Biggest Loser' that destroyed the health and mental wellbeing of fat folks, exploiting their suffering - not to mention glamorizing self-destruction and disordered eating for countless others," one person tweeted. "That is the OPPOSITE of self-love and health."
