In the 1980's, a health psychologistJohn de CastroMr. started investigating eating habits such as "What did you eat" "How many people did you eat"? Mr. Castro who gathered data on 500 eating habits by 1994 said that he found a tendency to "eat more quantity when eating more than one person than when eating alone".

Researchers other than Mr. Castro are also studying the difference in the amount of food that one eats when eating alone and when eating multiple people,Eat more ice cream by more than 40% more than one person"If you have more than one person eat macaroni and meat more than 10% more than one person"We report the result such as. Mr. Castro tries to eat too much when eating a lot, "Social promotion"We name it.

Mr. Castro and other researchers deny elements such as "hungry" and "mood" about why you eat more than a single person when eating in large numbers. Instead, Mr. Castro et al. Said that "why do not you eat alone, if you eat with multiple people, for a long time?" Is the reason why social encouragement occurs in meals.

Observation results at restaurants suggest that it has tended to increase the mealtime as the number of people in the group increases.Research in 2006Then 132 people were divided into groups of 1 person, 2 people, 4 people, and they had cookies and pizza with a time limit of 12 minutes or 36 minutes. As a result, the amount of food you eat at a certain time is nearly the same regardless of the number of people, and the longer you get the result that you will eat lots of quantity. The more you eat, the more we stay at the dining venue and as a result we will find new delicious cakes and fruits, so we will eat a lot.

Also, in the meal form such as parties and banquets, a tendency is observed that each participant believes that "this amount may not be enough for this amount" and orders a lot of dishes. As the number of participating people increases, the number of dishes ordered by each person increases.Peter HermanMr"Bounty hypothesisI named it. We say that we can eat a lot of dishes without feeling guilty by "ordering for others, not for myself".

The phenomenon of eating a lot of amounts when eating with multiple people occurs even if the other person eating it is not a real person. In a study conducted in Japan, it is shown that people who are instructed to eat popcorn "in front of a mirror" will eat more popcorn than people who were instructed to eat popcorn alone by one person it was done. It is often the result of this research that mirrors are installed on the walls of the restaurant and many people are pretending to be eating in a large space.

While many studies show that eating in large numbers leads to overeating, on the other hand, research results that "Eating with people can reduce eating less than usual" has also been announced. When obese children eat with non-obese children, they eat more than usualLess amountAs a result, when women eat with men, they eat more than women aloneLess amountThe results of the study are shown.

Although it has been found in previous studies that human eating habits tend to be influenced by social interactions, it is known that why humans have evolved that way is still to be detailed not. As a conceivable theory, "By combining the amount of food eaten by many people, it is possible to give food to many members in a hunter-gatherer society with little food to be obtained" "Children eat with knowledgeable adults It is possible to think of reducing the risk of eating dangerous things by matching them ".

In the worldNearly 30% of people are overweight, It is said that humans are becoming obese as a whole. We must be careful not to eat too much carelessly as we realize that "my diet is dependent on social relations and eat too much at the most when eating a lot" It seems likely.
