Many of us probably remember our parents telling us to watch out who we hung around with. If you spent time with trouble-makers, you were likely to get in trouble yourself.
It makes sense. But what about this? If you spend time with obese people, chances are better than average that you will become obese yourself. Sounds like silly speculation, right. Something that you might’ve read in The Secret. Like attracts like.
But guess what? That was the finding of mainstream Harvard scientists whose research results were published in the New England Journal of Medicine.
Obesity, they report, is socially contagious. “We find that a person’s chances of becoming obese increase by 57% if they have a friend who becomes obese, 40% if they have a sibling who becomes obese, and 37% if a spouse becomes obese,” say researchers Nicholas Christakis, MD, PhD, and James Fowler, PhD.
Mutual friends more than triple the risk to each other,” note Christakis and Fowler. “If one of the two [mutual friends] becomes obese, the chance for the other to follow suit goes up 171%.”
Yikes! This report came out in 2007. So I was wondering if this theory has been discounted in the past four years. Turns out there was a new report that came out in a journal called Obesity that confirms the early study that obesity is socially contagious.
So now we need some research to find out if hanging out with skinny people has a similar contagious effect.
