Losing Weight May Be Easier If You Hang Out with Skinny People

New research suggests it is more difficult to lose weight when a person associates with heavier people. Conversely, if a person includes thinner people in their social lives, they are more likely to lose weight.

The study by a Baylor University researcher explains that people who want to lose weight are less likely to experience weight discrimination and feel more comfortable with people whose body mass is similar.

Nevertheless, spending time with them may undercut success at weight loss, according to the study, published in the journal Obesity.

The findings should not imply that people attempting to lose weight need to find new friends, said lead author Matthew Andersson, Ph.D., assistant professor of sociology in Baylor’s College of Arts & Sciences.

“What we don’t know is what respondents are doing with their social contacts, whether through texting, in person, or on social media. They might be going out to eat; they might be going to the gym; they might be doing something totally unrelated. We just don’t know,” said Andersson.

Andersson conducted the research while at Yale University’s Center for Research on Inequalities and the Life Course.

The findings were based on an analysis of a Gallup Organization survey of 9,335 people aged 18 to 65 in American households. Researchers supplemented the data with questions, tracking for one year the participants’ self-reported social networking changes, and body mass outcomes.

Respondents identified the four adults with whom they spent free time most frequently, whether household members, relatives, or friends.

They also rated each contact’s body mass relative to their own, Andersson said. For the study, “we relied on how people perceived those in their network rather than actual weight measurements.”

Individuals were asked whether they wanted to lose, maintain, or increase weight. The study also assessed how often participants interacted with those they identified as frequent contacts, whether in person or by phone, email, texting, or social media, Andersson said.

Close friendships appeared to make a difference. That is, frequency of contact played a major role.

With fewer than 100 interactions with an individual during a year, changes in weight were linked to a fraction of a pound. But as interactions reached hundreds and even thousands, weight differences became more substantial.

Investigators believe future studies should investigate the nature of the associations; for example, whether increased contact reflects an activity such as joining a weight-loss group.

“Also, the desire to lose weight in itself may be linked to other health traits, such as whether they smoke,” Andersson said.

“It would be useful to have a more complete view of the individuals,” he said.

“Maybe someone has a certain personality type and wants to lose weight all the time, while another person might be trying to lose weight for a special occasion like a wedding.”
