Craving candy? Watching someone else scarf down sweet stuff can reduce urges: study

Scientists have found some Twix to minimize the itch to eat candy.

A study published in the journal showed that people who watched immer༺sive videos of other people eating candy had a significant decline in craving it☂.

The resea𓂃rch was inspired by the trend of mukbang videos — live streams in which the viewers watch the host eat for entertainment — which originated in South Korea.

“We were intrigued by the mukbang phenomenon where people seem to enjoy watching others eat large amounts of food, with some reporting feeling full afterward. We were motivated to find out if there was a way that we can explore this through a series of studies and determine if watching food consumption videos can have effects on their actual eating behavior,” co-author of the study Lee Hui Min, a graduate student from Nanyang Technological University’s Wee Kim Wee School of Communication, said in a .

Scientists from  wanted to determine if watching immersive video🅷s, such as mukbang, would elicit s൩trong cravings or unhealthy eating habits, such as binge eating.

However, results revealed that theseꦬ videos actually had the oppo🎉site effect.

Previous studies have discovered a l꧂ink between watching immersive videos and achieving a decreased appetite but never analyzed repeated exposure to such videos.

Researchers looked at 317 Singapore residents between the ages of 21 and 28, with the demographics of the group representing Singapore’s multi-racial society.

One group of participants would watch an immersive video of people eating M&M’s, repeated 30 times for a total of 8 minutes of viewing, while the control group watched a video of a single coin being put into a laundry machine 30 times.

Immersive videos transport the viewer into the video itself using innovative technologies su💎ch as virtual-reality or augmente🎉d-reality headsets, 360-degree videos and motion tracking, to allow the person to feel like an active participant rather than an onlooker.

After watching, the researchers would offer M&M’s to look at how repeated exposure to these videos affected a person’s cravings for candy.

They found that those who watched the candy-eating video had about onཧe-third less candy (32% to 38% less candy) on average — about three pieces less — compared to the control group, suggesting that repeated exposure to the eating videos makes the person believe that they themselves have consumed the candy, reducing the hunger for it.

NTU researche♓rs clarify that the reduced craౠvings were due to habituation — an effect that reduces a physiological and behavioral response as a result of repeated exposure and stimulation.

“Mukbang videos might be satisfying cravings and potentially causing people to consume less food. It appears that seeing so much food being consumed has the possibility of inducing habituation among viewers leading to some kind of satiation,” Benjamin Li Junting, assistant professor at NTU’s Wee Kim Wee School of Communication and leader of the study, said.

Habituated people were less i🙈nclined to respond to food cues, leading ༒to a lower desire to actually eat the food.

“Our findings suggest that viewing food-related immersive videos may be a way to induce satiation and reduce the amount of food consumed after watching. This could be helpful for individuals looking to curb their appetites or manage compulsive eating behaviors,” Li explained.

He continued, “For example, clinicians might tap into habituation as a psychological mechanism in therapy interventions for patients. This can possibly appear in the form of repeated viewings of other people eating food, leading to reduced desire to eat or induce feelings of satiation or fullness.”

The ♊authors added that the results could help provide an understanding of how mukbang videos effect eating habits that could inform strategies for interventions or guidelines for how to portray healthi🗹er eating behaviors in the context of media.

Researchers also tested adding exposure smell to the study to discover how visual, auditory and olfactory stimuli combined can affect a person’s eating patterns and cravings.

Since scent can play🌼 a large role in th𒈔e perception of food, it can help determine if the added exposure would impact food-related responses.

Scientists repeated the original experiment but added the diffused scent of chocolate while participants watched the same video 30 timeꦡs.

Results showed that participants actually consumed 11% fewer M&Ms — or one less piece of candy — than they did when watching the video without the scent. Adding the cue of smell showed that participants ate an average of four pieces less candy overall comparﷺed to the contro💛l group.

“Smelling chocolate had a similar, habituating effect as watching people consuming chocolate and decreased the participants’ desire for the candy,” Li said.

“Our study found that exposure to food scent cues alongside visual food cues can lead to a sensory stimulation of tasting the food. Some researchers have termed this embodied cognition,” he added. “This makes sense as the experience of food consumption typically involves more than one sense, and the addition of a food scent appears to enhance the effect of one feeling satiated, or full.”

However, the NTU team of researchers shared that they will be conducting further research in order to see the longterm effects of both visual and olfactory exposure on a person’s craving for a food item.

“As we only tested a chocolate scent in our study, we are keen to explore if the results might be different for other types of smells, for example, savory scents like garlic, or scents of greasy foods like french fries,” co-author Lee explained. “There is also the question of whether the length of scent exposure will have a stronger influence, and whether the results of habituation through watching 360-degree videos persist over time.”

Li added, “In future studies, we hope to test the long-term effects of repeatedly watching such immersive videos. We hypothesize that it would have a long-lasting effect on eating behaviors, as the visual and olfactory stimuli could be learned by participants, such as in the well-known physiology experiment Pavlov’s Bell, conducted by Russian physiologist Ivan Pavlov, where subjects learned a behavior or bodily reaction after being repeatedly conditioned to stimuli, such as an audible or visual cue.”
