Researchers from Nagoya University in Japan found that facing the mirror or facing a photo of their own meal, you will have more appetite!
Compared with eating alone, when people eat together with others, they evaluate food better and eat more. This is the so-called companionship to enhance appetite, but the mechanism of companionship to enhance appetite is not clear.
Now, researchers from Nagoya University have found that a person who has a face or a photo of himself can achieve the same effect. This research was recently published in Physiology & Behavior.
“We want to know the minimum requirements for companionship to enhance appetite.” Ryuzaburo Nakata, the first author of the paper, said, “Do you really need someone else to be present? Or is it enough to show that other people are there?” The researchers found that when people can pass the mirror When they saw themselves, they rated food more and ate more.
The research team initially conducted research with a group of elderly volunteers. Increasing the happiness of eating alone is very relevant to the elderly, as previous studies have shown that older people often eat alone. But when the researchers repeated the experiment on young adult volunteers, they found the same phenomenon: when they were facing the mirror, their appetite was stronger, indicating that this phenomenon is not limited to the elderly.
In the follow-up study, the researchers changed the mirror to a photo of the volunteers eating themselves, and they found that the photos also increased the appetite of the volunteers. The unexpected result is that a photo of a person eating may be enough to achieve the effect of “accompanying to enhance appetite”.
“Research has found that for older people, the level of enjoyment of food is related to their quality of life, and frequent eating alone can lead to depression and affect appetite,” said research author Nobuyuki Kawai. “For older people who often eat alone, our findings show a potential way to increase the appeal of food to them and improve their quality of life, such as those who are widowed or away from their partners.”
