Our friendships can have quite an influence on how we live our lives. There’s a tangible link between the way we behave and the men and women we have friendships with. And yet we’re likely to have presumed this commonality concerned our likes and dislikes - for example we enjoy the same musical tastes as our friends, or hold similar political views.

It’s now becoming apparent as well that this common theme might extend to weight. We will eat more when in the company of good friends who eat more. A small study undertaken in America found that overweight kids and teenagers ate more when they were eating with a friend who was also overweight, than when they ate with a normal weight child.

It appeared in fact that everyone in the study got through more food when with friends than with strangers. But it was when the heavier friends teamed up that the most calories were consumed. The research was featured in the American Journal of Clinical Nutrition. It illustrated the part friends play in the actions of each other.

Certainly, it’s human nature to feel more secure in our actions when we’re amongst friends. We’re not so self-aware with people we like and know well. But there’s possibly more to it than that - we intuitively view friends as permission givers. We grant them the right to define acceptability - in this case in relation to food quantities.

The study took 65 young people of mixed weights and observed them for 45 minutes. There were pairs of friends, and pairs of strangers. They were given games to entertain themselves, along with snack food, fruit and veg.

All the ones who teamed up with a friend ate a larger amount than the rest. However it was the pairs who were both overweight who consumed the most in total. And the variations were considerable, as shown below.

Nearly seven hundred and fifty calories per person was consumed by the larger pairs of friends. Heavy kids with standard weight chums ate just under 450 cals, and standard weight kids ate approx 500 cals whatever weight their mate was. This influence extends to smoking and drinking as well with young teens.

This led the researchers to suggest that young people’s eating habits are largely determined by their social network. Yet this power of association can be beneficial, as positive influences are just as possible as negative ones. Healthy nutrition then should be part of every child’s curriculum.
