Naturopathic Solutions

This NYT article by the prolific health and fitness writer, Gina Kolata, is one of several in the national newspapers this week which reports on a study in the New England Journal of Medicine. 

The  study found that if you have a friend, spouse or relative who becomes obese, you are much more likely to become obese, or in the words of the study itself:  “Network phenomena appear to be relevant to the biologicand behavioral trait of obesity, and obesity appears to spreadthrough social ties.”

Some in the media have expanded this language “spread through social ties” interestingly saying that obesity is “contagious.” 

Clearly what is at work here is the reconfirmation of a very old phenomenon—we are influenced in many direct and subtle ways by the habits, actions and characteristics of those close to us—note that a neighbor’s obesity did not show causality because we aren’t necessarily socially close to our neighbors..

Americans do pay attention to the way their close friends act and live.  We tend to wear the same clothes, go to the same stores, take the same vacations, see the same movies and listen to the same music—to some extent.  For example, if a close friend or sibling returns from a European vacation, we are likely to follow.   And, if close friends or siblings become fat, well, gradually our norms for what is acceptable weight-wise may loosen and we are probably less resistant to gaining weight.

I think that all that is going on here is re-affirmation of  age old peer group pressure/influence as it pertains to obesity.  The study results are correct and meaningful in this respect.  However, the idea that obesity is somehow “contagious” is somewhat off the mark and summarizes the problem in an unhelpful way—because Americans are always searching for that reason why obesity is not their fault.

So, although your close friends may have an influence on your obesity norms, you certainly can’t blame them for your own obesity, anymore than you can blame them for your wardrobe, the kind of car you drive or your last vacation.

The first step in fighting obesity is take responsibility for your own BMI.
