There’s new evidence that your choice of dining companion could have a big influence on how much you eat too.

Researchers at the University of New South Wales studied the psychological effect known as social modelling which leads people to eat less than they normally would if alone, when their companion consumes a small amount of food.

Their recommendation – dine with a light eater if you want to consume less.

The study’s lead author, Associate Professor Lenny Vartanian, says that in social situations the appropriate amount of food to eat can be unclear.

“Internal signals like hunger and feeling full can often be unreliable guides. In these situations people can look to the example of others to decide how much food they should consume,” he said.

Associate Professor Vartanian and his colleagues analysed the results of 38 studies in which the amount of food that people ate in company was measured. The results are published in the journal Social Influence.

“The research shows that social factors are a powerful influence on consumption. When the companion eats very little, people suppress their food intake and eat less than they normally would if alone,” he said.

“If the social model eats a large amount, people have the freedom to eat their normal intake, or even more if they want”.

The effect is observed in many different situations: with healthy and unhealthy snack foods, during meals, when the diner has been deprived of food for up to day, and among children, and it occurs independent of people’s body weight.

“It even occurs when the companion is not physically present and diners are simply given a written indication of what that other person ate,” said Associate Professor Vartanian.

The effect appears to be stronger in women than men, and this may be because women tend to be more concerned about how they are viewed by others when they are eating.

“Or the explanation could be more mundane, that undergraduate males participating in the research are over-enthusiastic about an offer of free food,” he said.

The research shows that the modelling effect is stronger in older children than in younger children, which also suggests that relying on external rather than internal cues for how much to eat is a learnt behaviour.

“Media reports usually focus on how portion size affects how much we eat, but this modelling effect deserves as much attention, because of its big impact on people’s ability to regulate their intake of food,” Associate Professor Vartanian said.

Does this new study explain your eating habits? How much do you engage in ‘social modelling’ when you’re dining with a friend? Do you tend to eat less when your friend is a light eater too?

  1. I am the opposite. Eat less at home than out. Control my intake, but when out the meals are so large And I don’t like to waste food so eat it all and usually feel disgusting afterwards. Have a friend who usually likes to share a meal, so she is good for the waistline. Need more of them.

  2. What a load of rubbish. I don’t eat much, but it has never effected the people I dine with, they are all much bigger eaters than me and all enjoy their food. Sometimes I really think those researchers need to get a real job or just get out into the real world for a while.
