FBI Reform: Eurasia Review: People Eat More When Dining With Friends And Family

Listen to this article

People eat more with friends and family than when dining alone – a
possible throwback to our early ancestors’ approach to survival,
according to a new study. This phenomenon is known as ‘social

Previous studies found that those eating with others ate up to 48%
more food than solo diners and women with obesity eating socially
consumed up to 29% more than when eating alone.

Experts at the University of Birmingham led a team of researchers in
Britain and Australia who found that eating ‘socially’ has a powerful
effect on increasing food intake relative to dining alone, after
evaluating 42 existing studies of research into social dining.

They explain that ancient hunter gatherers shared food because it
protected against periods of food insecurity – this survival mechanism
may still persist today, leading to people eating more with friends and
family because:

  • Eating with others is more enjoyable and enhanced reward from social eating could increase consumption.
  • Social norms might ‘permit’ overeating in company but sanction it when eating alone.
  • Providing food becomes associated with praise and recognition from friends and family, strengthening social bonds.

Research leader Dr Helen Ruddock, from the School of Psychology at
the University of Birmingham, commented: “We found strong evidence that
people eat more food when dining with friends and family than when
alone. However, this social facilitation effect on eating was not
observed across studies which had looked at food intake amongst people
who were not well acquainted.

“People want to convey positive impressions to strangers. Selecting
small portions may provide a means of doing so and this may be why the
social facilitation of eating is less pronounced amongst groups of

“Findings from previous research suggest that we often choose what
(and how much) to eat based on the type of impression that we want to
convey about ourselves. Evidence suggests that this may be particularly
pronounced for women eating with men they wish to impress and for people
with obesity who wish to avoid being judged for overeating.”

The study highlights that, as with many other species, humans tend
to share a common food resource. Most humans are no longer
hunter-gatherers, but mechanisms similar to those that once served
efficient foraging continue to guide our dietary behaviour.

Recent and rapid transition to a dietary landscape in which food is
abundant has created forms of ‘evolutionary mismatch’ – inherited
foraging strategies no longer serve their former purpose.

Researchers note that, in the case of social facilitation, we have
inherited a mechanism that once ensured equitable food distribution, but
now exerts a powerful influence on unhealthy dietary intakes.

The same process has been observed in chickens, rats, gerbils and
other species, suggesting it serves an ultimate purpose. Individuals
compete for resource and research suggests that eating more than others
is likely to lead to ostracism, which, in turn, reduces food security.

This creates a tension between an individual ‘being seen’ to share food altruistically and eat as much as they need.

“A solution to this tension may be to eat at least as much as
others in the group – individual members match their behaviour to
others, promoting a larger meal than might otherwise be eaten in the
absence of this social competition,” commented Dr Ruddock.

“What we describe as ‘social facilitation’ can be seen as a natural
by-product of social food sharing – a strategy that would have served a
critical function in our ancestral environments. This also explains why
it is more likely to occur in groups with individuals who are familiar
with each other.”
