New study says you’re fat because your friends make you eat.

Obesity spreads through social networks, according to the study, so if your friends put on weight, you’re more likely to put on the pounds, too. Your family members or spouse can also influence you; as they get heavier, you’re more likely to gain along with them. But, your friends—even if they don’t live anywhere near you—have the most sway. A close friend’s weight gain can even be downright dangerous.

Harumph!  With friends like that, who needs anemia?  [Sorry, couldn’t resist]
