Yes according to a study published by the New England Journal of Medicine. Our social circle can have a dramatic impact on our own weight.
Obesity, it turns out, is infectious. On average, having an obese friend made a person gain about 17 pounds. In fact there is a better than a 50/50 chance that you can predict someone’s weight health by looking at those in their immediate social circle.
And, it even seems to infect at a distance: friends who live far away and see each other infrequently are just as influenced by each other’s weight gain than friends who live near one another.
We tend to pattern our behaviors after our friends and establish personal norms that reflect our social network. Friends and family members – and even co-workers – tend to shape our choices. Light up or lace up? Hit the gym, or beers at the bar? It often depends on what those around us are doing. In fact some social ties have a stronger impact than even spouses and siblings.
The impact of this snowball effect around obesity is huge for employers. It is estimated that this country spends over $150 billion a year on diseases related to obesity like heart disease, hypertension and diabetes.
However there is good news here too: the same ripple effect through our social networks that causes obesity can also create positive health changes. Studies have shown that getting friends, family or workplace groups involved in a nutrition/physical activity programs is contagious. By participating in programs with others it is proven that more weight is lost and kept off longer than doing it alone.
One trend that’s catching fire is the use of healthy social competition within the workplace. Done right, this kind of activity can spread virally, drive new social norms around eating, exercise, and weight management, and even add a dimension of freshness and fun to employee health initiatives.
We’re doing our part to spread positive health contagion through employer-based social networks. In late May we deployed web and mobile technology that’s helping a whole bunch of employers across the state of Minnesota get healthy and fit – through a cross-company competition rolled out by the Alliance for a Healthier Minnesota. It’s the “Biggest Loser” corporate challenge. For the latest standings check out the leaderboard at www.competeforhealth.org.

Good health can be contagious too – let’s spread some around.
