Kelly Clarkson's Weight Loss: Her Own Words vs. the Viral Deepfake Ads

Search for Kelly Clarkson's weight loss and you'll find two completely different stories tangled together. One is a real, on-the-record account she's given in interviews since 2018 — a diet change, a diagnosis, a doctor she avoided listening to for two years, and eventually a medication she's named only by what it isn't. The other is a set of AI-generated video ads that put words in her mouth about a gelatin recipe or a baking-soda drink she has never mentioned once, in any interview, ever. We checked both threads against the actual record.

What Kelly Clarkson has actually said

The first time Clarkson spoke publicly about a real weight change was in 2018. Talking with Hoda Kotb on TODAY, she said she'd lost weight after adopting the eating approach described in Dr. Steven Gundry's book The Plant Paradox, which centers on cutting out lectin-containing foods — beans, most grains, dairy, and certain vegetables.^[1] Clarkson was direct that this wasn't a weight-loss plan in the usual sense: she'd been diagnosed with an autoimmune condition and a thyroid problem, said her lab numbers improved after the diet change, and specifically noted she "hadn't worked out at all" during this period.^[1] That's a materially different story from what circulates online now, and it's worth noting on its own: her earliest public weight-loss account was about managing a diagnosed health condition, not appearance.

The bigger, more recent chapter started getting real interview attention in January 2024. In a People cover story, Clarkson attributed a further round of weight loss to finally following medical advice she'd been putting off: "I dropped weight because I've been listening to my doctor — a couple years I didn't."^[2] She described a protein-focused diet ("a protein diet is good for me anyway... I'm a Texas girl, so I like meat"), followed "90 percent of the time," plus an increase in daily activity after relocating from Los Angeles to New York City — "walking in the city is quite the workout" — along with infrared saunas and cold plunges as general wellness habits.^[2]

In May 2024, on her own show and covered directly by NBC News, ABC News, and E! News, Clarkson confirmed for the first time that medication was part of the picture, and addressed the Ozempic speculation head-on: "Everybody thinks it's Ozempic. It's not." She described it only as "something that aids in helping break down the sugar — obviously my body doesn't do it right," and said she'd been diagnosed as prediabetic, with her doctor pushing her toward treatment "for like two years" while she resisted out of concern about her existing thyroid condition — until, in her words, "my bloodwork got so bad."^[3][4][5] She has never named the specific medication beyond ruling out Ozempic, and no outlet we checked has independently confirmed what it is. We're not going to guess at it here. She also named the moment that pushed her to act: watching a recording of one of her own performances and not recognizing herself.^[4]

One more honest detail worth including: Clarkson faced real public pushback after this reveal, specifically because she'd earlier credited walking and diet alone, and some fans felt the medication disclosure came only after direct questioning rather than upfront.^[3] We're not litigating that criticism here — just noting it's part of the actual public record, not something we're smoothing over.

Two things are consistently absent across every one of these real interviews, across six years and multiple outlets: gelatin, and baking soda.

The viral "pink gelatin" ad: a documented deepfake, not a Kelly Clarkson quote

The most current version of this misattribution is a "pink gelatin" or "Jell-O diet" recipe video that circulated widely on social media in spring 2026. TODAY.com reported on May 1, 2026 that the ad campaign uses AI-generated likenesses of four real public figures endorsing the recipe: Oprah Winfrey, Michelle Obama, Kelly Clarkson, and Dr. Mehmet Oz.^[6] None of them created, endorsed, or appeared in the actual footage. Oprah's team told TODAY that "unless something is posted on her personal IG page [@oprah], it is not something she is involved in," and a representative for Dr. Oz separately confirmed he "is not involved with the Jell-O tip now appearing online."^[6]

The story got real, human confirmation from an unlikely source: Real Housewives of Beverly Hills star Kathy Hilton told TODAY she'd tried the recipe herself after seeing what she believed were genuine endorsements. She said she initially lost a small amount of weight, then developed severe bloating — "I was so bloated I could not fit into anything. It has messed up my whole entire system" — before learning the endorsements were fabricated: "They lied to me. It was all IA — AI."^[6] Fact-checking outlet Snopes separately reviewed the same "pink gelatin" trend and reached the same conclusion, finding no credible evidence that Oprah, Dr. Oz, Kelly Clarkson, or several other named public figures had endorsed the recipe or products sold alongside it.^[7]

This is the same broad pattern our own reporting has covered before on this desk — a real person's face and voice, lifted and reassembled by AI into an endorsement they never gave. Our general explainer on how to recognize this pattern is here: The Deepfake Ad Playbook.

Older ads, and the baking-soda version

The gelatin video isn't the first time Clarkson's likeness has been used this way, and it likely won't be the last. Fact-checking organization PolitiFact documented a separate case as far back as October 2023: a Facebook ad used real footage Clarkson had posted to her own Instagram in June 2023 (promoting her album Chemistry), altered with AI to make it appear she was endorsing a weight-loss pill or gummy from an unnamed "pharmaceutical company," linking to a fake sales page. PolitiFact rated the claim False and reported that "Clarkson's publicist further told the Associated Press that Clarkson isn't a spokesperson for any weight loss products or programs."^[8] A separate consumer alert from NBC affiliate WHEC covered a related wave of altered videos — the outlet's investigator identified five separately altered deepfake clips of Clarkson circulating on Facebook, one falsely quoting her promising a large amount of weight lost within a short, specific window at no cost, "in limited quantities."^[9] That specific promise — a big number, a tight deadline, framed as free and about to disappear — is a manufactured-urgency pattern worth recognizing on its own, independent of whose face is attached to it.

There's also a baking-soda-specific variant worth naming directly, because we've already reported on it from the other direction. Our own review of the AlkaSlim supplement documented a deepfake video campaign, first reported by fact-checker Jordan Liles on July 28, 2026, that uses a fabricated Oprah Winfrey endorsement and an AI-generated likeness of a real Yale obesity-medicine physician, Dr. Ania Jastreboff, to push a "$1 baking soda recipe" toward an AlkaSlim purchase — Yale's own faculty page confirms videos of Dr. Jastreboff endorsing weight-loss products are fraudulent.^[10] Consumer-alert sites tracking this same ad family separately describe a Kelly-Clarkson-fronted version of essentially the same baking-soda-and-AlkaSlim script, with her likeness swapped in for Oprah's.^[11] We want to be precise about our confidence level here: the Oprah/Dr. Jastreboff version is independently fact-checked by a named investigative journalist against Yale's own public statement, which is why we reported it as confirmed on our AlkaSlim page. The Kelly-Clarkson-fronted version of that same script is documented only by scam-tracking sites, not yet by a fact-checker of that caliber — still worth knowing about, but we're flagging it as a lower-confidence report rather than presenting it with the same certainty. Either way, the underlying mechanic is the same one PolitiFact and TODAY both documented: one video template, one product, and an interchangeable celebrity face bolted on.

The bottom line

Kelly Clarkson has an unusually well-documented, years-long public record of talking about her own weight loss — a 2018 diet change tied to a real diagnosis, then a 2024 combination of doctor's advice, a protein-focused diet, walking, and a prescription medication she's declined to name beyond ruling out Ozempic. At no point in any of that record does she mention gelatin or baking soda. Separately, and verifiably, her face and voice have been used without her involvement in at least three distinct AI-generated ad campaigns since 2023, fact-checked by PolitiFact, TODAY, Snopes, and an NBC affiliate, all reaching the same conclusion: she didn't say any of it. If you see a video of Kelly Clarkson describing a kitchen-cabinet weight-loss recipe, the honest, sourced answer is that it isn't her.
