We are besieged with articles and studies about the dangers of trans fat, sugar substitutes, too much salt in processed foods, irresponsible advertising to children, portion size, stress and lack of time to prepare meals, which can lead to calorie-laden choices and the dreaded obesity epidemic.
After reading an article recently in the Chicago Tribune about the latest obesity findings, the results of a study funded by the National Institute on Aging and published in the New England Journal of Medicine, I am even more worried, stressed and depressed.
I always thought the cause of obesity was either in the genes, diet choices, portion distortion, lack of exercise, workaholic behavior or a combination of those factors. But now comes the latest bugaboo: one's social network. Yes, it's the people around you that cause you to be obese, according to researchers at Harvard Medical School.
After analyzing the social networks of 12,067 persons, who participated in the Framingham Heart Study for more than three decades between 1971 and 2003, researchers concluded it's one's social network of family and friends that makes you fat. And to rule out the idea that "birds of a feather flock together," friends who were both obese at the beginning of the Framingham study were excluded.
Co-author of the study, Dr. Nicholas Christakis of Harvard Medical School, says a person's chances of becoming obese increases 57 percent if someone he considers a friend becomes obese. Even more upsetting is that if the two people name each other as a friend, the chance for the other to follow suit skyrockets 171 percent.
Here's the final dagger to the heart. Although the authors say they are not suggesting people kick their overweight friends to the curb, they think expanding one's social network to include more people with a healthy weight is a good idea. Study co-author James Fowler suggests you "encourage your friends to change their behavior so you can act in concert with them."
