Millennials Raise Concerns Over Gen Z’s ‘Dangerous’ #Y2KSkinny Diet Trend Spreading on TikTok.

 Millennials Warn Gen Z About Dangerous #Y2KSkinny Trend Resurfacing on TikTok.

Millennials who lived through the harmful beauty standards of the early 2000s are speaking out as the controversial “Y2K skinny” aesthetic resurfaces on TikTok, alarming body positivity advocates and mental health experts.

One voice leading the charge is Kaila Uli, a 33-year-old model and content creator who’s gone viral for calling out the platform’s obsession with the ultra-thin “Y2K body” trend. Uli, who grew up modeling during the height of the original thin-obsessed era, warns that Gen Z is unknowingly glamorizing a time defined by extreme dieting, disordered eating, and toxic body ideals.

“My first thought was, ‘No, we can’t go back here,’” Uli told Newsweek.
“These girls don’t understand how absolutely dangerous trying to achieve a Y2K body was. People starved themselves, used drugs, ended up in hospitals, and did extreme diets like the lemon cayenne cleanse — all to look emaciated.”

A Familiar and Harmful Cycle

Uli remembers firsthand how damaging that culture was. From being sent home from castings for being "too fat" to developing anorexia and bulimia, she says the pressure to be thin began early.

“I started dieting at 14 after seeing photos of Jessica Simpson being called obese,” she shared.
“I don’t want to see another generation destroy themselves chasing a body type that nearly killed me.”

Despite recovering from her eating disorders, Uli says the resurgence of “heroin chic” aesthetics on platforms like TikTok is deeply troubling. Hashtags like #Y2KSkinny and #2000sSkinny are trending once again, often paired with “thinspiration” content promoting starvation and crash diets — eerily similar to the pro-ana forums of the early internet.

Viral Video Sparks Online Support

Uli’s now-viral Instagram video calling out the #Y2KSkinny trend has garnered more than 2 million views and sparked a flood of emotional responses.

“They don’t remember how bad it was,” Uli says in the clip — a message that resonated with viewers who lived through the original Y2K era.
“Raise your hand if you’ve been victimized by Y2K standards,” one commenter wrote.
“Thank you! I’m glad someone said it,” added another. “They’re trying to take us back there.”

Experts Warn of TikTok’s Toxic Diet Culture

Mental health professionals echo Uli’s concerns. TikTok’s “SkinnyTok” subculture has come under fire for promoting starvation, toxic discipline, and unrealistic body goals — often masquerading as self-improvement.

“This mindset dismisses the complex realities of genetics, mental health, and social factors,” says Stephen Buchwald, a therapist at Manhattan Mental Health.
“Seeing curated, unrealistic images of thinness every day can lead to anxiety, depression, and a dangerous cycle of low self-worth.”

Some of the phrases gaining traction online sound dystopian — or worse, familiar. One viral quote: “If your stomach is growling, pretend it’s applauding you.”

A Call for Realistic, Healthy Standards

With the growing popularity of weight-loss injections like Ozempic and the glamorization of extreme thinness, experts and advocates are urging TikTok users — especially Gen Z — to critically question the content they consume.

Uli hopes her message continues to spread and serve as a warning.

“Not everyone survived that era,” she says. “We can’t afford to go back.”
