Find Healthier Friends
That friend who always wants to go out for chili cheese fries and beers? Keep him at arm's length. Sure, there's a time and a place for bar food, but Bryant says it's important to choose friends who want to be active with you too. "Find friends who want to go for a walk," he says, adding that these are the friends you also should take to lunch. "Research shows that friends who are more thoughtful with their food choices tend to help us be more thoughtful."
In a large, longitudinal study published in the New England Journal of Medicine, researchers examined the social connections of more than 12,000 participants over 32 years. The study found that your chance of becoming obese increased 57 percent if a friend was obese. Clearly, the point here isn't to shun your unhealthiest friends. Instead, make mindful choices when you're out and one person opts for the loaded nachos.
