A teenager picks up their phone before bed and within minutes is watching someone devour a towering fast-food burger, recreate a viral pasta dish, or walk through a bodybuilder’s daily meal plan. Suddenly, out of nowhere, hunger hits. For millions of American teens, this is a near-nightly experience, and a new study captures just how real that pull feels to the teenagers living it.
Researchers at the University of Minnesota ran focus groups with 25 high school students to explore how TikTok shapes what teenagers eat and whether parents play any role in softening that influence. What they found offers a window into how food served up by TikTok’s feed can work its way into teenagers’ cravings, and how far outside the picture most parents are.
Trending recipes, restaurant ads, influencer meal showcases, and viral food challenges all appeared repeatedly throughout the day. When the food looked good on screen, teens reported feeling an almost urgent desire to eat it.
One participant summed up the frustration of seeing something appetizing and not being able to get it immediately: “It’s across the world, we can’t get it! And also it’s like, even if it’s not about money, you can’t get what they have right now, like you want it right now.”
Not all food content hit equally. Teens were more likely to act on what they saw when they trusted the person showing it. A blue checkmark badge, a large following, or a perceived “good body” could push a teenager to try a new food or change how they eat entirely.
One male participant described adjusting his diet after watching a muscular creator on TikTok: “I click on his account and see what they’d be eating. And then I sometimes change how I eat, like to try to match it.”
Perhaps the most telling finding was how little most parents were involved in their teenagers’ TikTok habits, at least as the teens described it. Many participants said their parents either didn’t know or didn’t care what they were watching. Some teens said they wished their parents paid more attention. Others valued the independence.
A smaller group, though, described something worth paying attention to: when parents were physically present or prompted family activities like shared meals, teenagers naturally used TikTok less. That reduced screen time meant less exposure to food content, which researchers described as indirectly protective.
Even more powerful was what happened when parents actually talked with their teens about what they saw on TikTok. Teens whose parents expressed healthy skepticism about influencers or diet-related content described carrying that critical mindset into their own independent viewing. One participant recalled her mother’s advice: her mom had told her that the people on TikTok are living a different lifestyle and have different body types, and that even after following every step they give, she would not end up with the same results.
