Hey, Associate Professor of Obstetrics, Gynecology, and Reproductive Biology Karin Michels! A study just came out saying that obesity runs within social groups. So does my Felipe’s habit adversely affect the health of my friends?

“The bottom-line answer is probably yes, because your friends are going to be going with you when you’re frequenting those various eateries. What you should do is be a role model—say, ‘Lets go to the organic raw food place instead.’ You can turn this around. It’s up to you, and its under your control. So if you love your friends, choose eating at healthy places!”
