Drinkers, smoker and overweight Americans are around more people like themselves than counterparts

If you want to lose weight and quit smoking and drinking, hang out with fit sober non-smokers.

In the recent Gallup annual Consumption Habits survey, researchers asked responders if they spend time with smokers, drinkers and overweight people and had the responders identify themselves as such. Americans who smoke or drink are much more likely than those who don’t to have close friends and family who do the same. Smokers are more than twice as likely as nonsmokers to say their family and friends includes some or many smokers. Drinkers, as well, are over twice as likely to say their family and friends includes some or many drinkers. Also, 46 percent of adults who self-identify as overweight versus 30 percent of those whose weight is "about right" say they have some or many overweight friends.

Sixty percent of Americans say they drink alcohol at least occasionally, 45 percent say they are overweight, and 19 percent say they smoke cigarettes. Almost four in 10 Americans say they have some or many friends and family who are overweight. Another 45 percent say they have only a few who are. One in four Americans says they have some or many friends and family who smoke. However, a third of Americans say they have no friends or family who smoke, more than say the same about drinking and being overweight.
