A new study led by the University of Bristol suggests that people on a diet tend to spend more time looking at high-calorie food content on social media, but may actually end up eating less when faced with the real thing.

In other words, watching the food could help curb the craving.

Researchers found that participants who were dieting lingered longer on videos of indulgent foods compared with non-dieters, even when healthier options were available alongside them.

In one experiment involving chocolate desserts, dieters spent about 30% more time watching videos of high-calorie treats.

But when the participants were later given actual chocolate, the same group showed significantly more restraint, consuming less than those who were not dieting.

“It may sound counterintuitive, but our findings show that people, particularly those trying to control their diet, can use visual food content as a self-regulation tool,” said lead author Esther Kang from the University of Bristol.

The research suggests that engaging with food imagery, from short-form videos to curated social media posts, may offer a kind of “safe outlet” for cravings.

“Engaging with food imagery may help satisfy cravings without actual consumption,” Kang said, adding that the accessibility of such content today could make it a simple and non-invasive way to support dietary goals.

The study involved 840 participants aged between 19 and 77, combining online surveys with controlled lab experiments.

In another test, participants were shown videos of junk food such as pizza and chips alongside healthier options like salads, yoghurt and smoothies.

Once again, dieters were drawn to the less healthy options, spending around 50% longer watching them than non-dieters.

Kang described this behaviour as a form of “digital foraging”, where people seek out visual cues of indulgent food without necessarily acting on them.

“Contrary to what might be expected, when given the chance to actually eat the food, they exercised much more self-control,” she said.

With weight loss continuing to be a major focus for many, the findings point to an unexpected role for social media in shaping eating habits.

While Kang stressed that food imagery is no substitute for real dietary discipline, she noted that it could complement efforts to manage cravings.

“We’re not claiming imagery can replace the desire to eat chocolate or other indulgent foods, but it may help people reduce or avoid overindulgence,” she said.

So the next time you catch yourself watching yet another slow-motion cheese pull, it might not be sabotaging your diet after all – it could just be helping you stick to it.
