It's not that people who are overweight or obese seek each other out, but rather that friends are growing fatter together.
"What appears to be happening is that a person becoming obese most likely causes a change of norms about what counts as an appropriate body size. People come to think that it is okay to be bigger, since those around them are bigger, and this sensibility spreads," Dr. Christakis said.

Date: 2007-07-26 04:08 pm (UTC)I was a bit surprised by the statement that 59% of Canadian adults are over weight (esp. after spending a weekend in Montreal and noting how healthy everyone looked), but then realised that they're probably using BMI which puts me at the low end of overweight. It would be so so simple to add a flag for activity level and adjust the ranges to better account for muscles versus fat.
