I tried to scrub weight loss from my FYP. Here's the truth

If you tried to scrub weight loss content from your TikTok FYP, Mashable's hands-on test shows TikTok's Not Interested button and buried settings are not enough. Months of tapping disinterest still left GLP-1 ads, Wegovy promos, and body-transformation posts flooding the feed.

Remember when a single thumbs-down felt like a shield? That was the old promise of algorithm control. In 2026, a Mashable reporter spent months trying to purge diet culture from a For You Page and found the tools work more like a polite suggestion than a blockade.

Key Takeaways

• Tapping Not Interested does not update your ad or topic preferences; it only signals dislike for one specific video.
• Even after moving Health and Fitness to see less and muting weight-management ad topics, GLP-1 and weight-loss ads kept appearing months later.
• A Northeastern University study found disliked topics can return within minutes once users stop signaling disinterest.
• Instagram's main feed is easier to control than TikTok's FYP because it is built around accounts you follow, not endless strangers.
• Experts recommend repeated settings audits, screen-time limits, and curating who you follow rather than trusting one button.

Why does scrubbing weight loss from your FYP feel impossible now?

The short answer is money, politics, and design. Chase DiBenedetto, writing for Mashable, describes smashing TikTok's Not Interested button on posts about gut-health weight loss, Serena Williams Ro ads, and snack-tin glow-up vlogs. She believed the tool would push back against companies hawking GLP-1 medications and creators disguising restrictive eating as trends.

It did not work that way. Weight-loss influencers kept infiltrating her daily scroll. Roughly every third ad promoted a weight-loss service. She was seeing GLP-1 influencers more often than friends. That gap between expectation and reality is the heart of this story.

More than 30 million Americans will have an eating disorder in their lifetime, and every 52 minutes someone dies as a direct consequence, according to the Strategic Training Initiative for the Prevention of Eating Disorders (STRIPED) at Harvard. Against that backdrop, a feed that will not stop selling thinness is not a minor annoyance.

What did years of Not Interested actually change?

After what she estimates as years of curation, DiBenedetto checked her advertising settings and found a surprise. Health and Wellness was marked Interested. Weight management sat at No preference. Content topic sliders, adjustable from See More to See Less, were still at default, including Health and Fitness. There is no dedicated slider for weight loss or body-focused content.

She had assumed aggressive Not Interested tapping was rewriting her account profile. It was not. The button works more like a thumbs down, nudging how the algorithm categorizes a single interaction. Block one GLP-1 creator and others still appear. The system registers that you disliked that video, not that you reject the entire category.

TikTok's own advertising guidelines prohibit exaggerated weight-loss claims and products like fat-burning pills. Community guidelines ban disordered-eating promotion, including sponsored posts. The platform says it aims for a body-positive environment. And yet the ads kept coming.

Can TikTok's hidden settings finally keep GLP-1s away?

DiBenedetto went deeper. She moved Health and Fitness all the way to see less and adjusted Fashion and Beauty. In ad controls at the bottom of settings, she used manage ad topics, muted advertisers, and found weight management only under Other. She stripped personal details like gender and age and cleared inferred preferences TikTok had assigned her.

The app warned changes might take 48 hours. She waited the full two days, then kept waiting for months. Ads appeared to worsen, echoing findings from a recent Northeastern study. Researchers used hundreds of bot accounts to test Not Interested, which they called the most effective explicit signal users can send. Even so, topics could reappear within minutes. When accounts stopped indicating disinterest, feeds were often dominated by that content again. TikTok declined to comment on the research.

Her ad log from May 2026 reads like a pharma billboard: two Wegovy semaglutide injection ads on May 9; TrimRX and Hers Wegovy on May 27; Ro semaglutide pens and a BitePal calorie-tracker ad on May 30. She blocked Ro. The brand returned anyway. Nearly two months after she began reporting, the flood had not stopped.

How does today's Instagram compare to the old TikTok FYP battle?

The problem is not TikTok alone. Instagram offers content preferences and a 30-day snooze for suggested posts from accounts you do not follow. Users can inspect and edit what the algorithm thinks they want.

Experts told Mashable the structural difference matters more. Instagram's main feed is not built to serve an endless river of strangers the way TikTok's FYP is. You can stay on Following and avoid Explore. On TikTok, most people live on For You, not Following. That architectural shift, from friend-centric scrolling to stranger-centric discovery, is a defining then-and-now shift in how diet culture finds you.

Meta was recently found liable for misleading consumers about platform safety and mental-health tools. DiBenedetto reports feeling somewhat safer on Instagram when she sticks to her main feed, but perfection is not the standard here.

What do eating-disorder experts say about feed control in 2026?

Jessica Scheer, CEO of the National Eating Disorders Association, tied the difficulty to a laissez-faire political moment around content moderation. Dr. Elizabeth Wassenaar of the Eating Recovery Center noted algorithms are designed to favor creators chasing views, not consumers seeking peace. Dr. Blair Burnette of Michigan State University's ARISE Lab explained that body-checking and anti-fat sentiment often evade systems trained on captions and keywords.

NEDA advises that algorithms retrain slowly, so repetition matters. Fixes are often temporary and may last only a few sessions before recalibration. Burnette recommends screen-time limits, apps like Roots, and intentionally following anti-diet creators while purging accounts that trigger comparison.

Where does the then-and-now lesson leave scrollers?

The nostalgic version of social media promised that your thumb could sculpt a safer feed. The 2026 reality, as Mashable documents, is messier. One button cannot scrub an entire industry. Settings exist, but they are buried, slow, and easily overridden by ad targeting and creator economics.

The practical takeaway is blunt: audit settings continuously, mute aggressively, limit screen time, and treat your follow list like a curated guest list. Big Tech and Big Pharma are betting you will not bother. Proving them wrong takes more than a single Not Interested tap.
