THIN

Jessica Simpson just debuted her post-baby body in New York City – an hour before her big reveal is set to air on Katie Couric's new talk show.

According to a new study published in the May 2012 issue of Psychological Science, men and women in sexy underwear ads are processed astonishingly differently by the human brain.

As if women didn't struggle with body image enough these days, the following news comes from Holland: "A former winner of the television show 'Holland's Next Top Model' has won a lawsuit against Elite Model Management after she was dropped for having hips the agency considered too large."

The New York Times recently featured a study of 6,000 Australian women that revealed significant weight gain after marrying or even moving in with a significant other. Keeping our waistlines while cohabiting in domestic bliss comes down to being vigilant with how we eat. And, perhaps we could all aim to be a little sportier with our significant others. Go bike riding, take up a class at the gym, train for a marathon, play kickball or the Wii, even. Or if you really aren't the sweat-in-public type, at the very least you could aim to have more athletic sex.

Mom always got on us about getting our Z's every night. As annoying as that could be, as much as we wanted to stay up and talk on the phone/watch late night TV/read magazines, she was on to something. And who is the most sleep-deprived in our culture? You guessed it: single, working women and mothers. What do you think, can you and your S.O. vow to get a full night of sleep every night for a month?

Having been an active participant in both fat and thin intimacy in the past year, it is very clear to me how much better it is to have sex when both partners are fit, thin, and healthy.

Em and Lo's Wise Guys tell us that men prefer sex without condoms. Sex without condoms is best. But they will settle for thin condoms, they say.

Seth Rogen has come out. (No, not out of that closet! But let's face it: the nice guys never make the tabloids!) More literally, the "Knocked Up" star has come out of hiding as a fro-rockin, chubby –but always charming– geek to reveal his leaner, greener self; his weight loss served as preparation for his upcoming role as lead in the big screen adaptation of "The Green Hornet", according to a Celebitchy report. "I certainly don't feel like a movie star – not in this body anyway," Rogen told the UK’s "Independent" in September. "I think when you do comedy, you play by a different set of rules. No one really wants you to be in that good shape. Being in good shape implies a level of vanity that isn't necessarily funny." Well, we still think he's funny. And that he's never looked better.
