What are the thin people really eating? The British Journal of Nutrition just published a study this month saying that the trimmest people, those who weighed the lightest, flaunted the slimmest waists, and were proud owners of the smallest hip circumference, had the highest levels of omega 3 fatty acids in their blood. After investigating the commonality, I found that these people were in fact not freebasing flaxseed oil. They were, however, loading up on foods that were rich in omega 3s -- grass-fed beef, flaxseed, soy, salmon, etc. No one knows for sure what omega 3s do for the diet exactly ... they may stimulate hormones that make you feel full, and they have been shown to improve circulation, which can also aid in weight loss and reducing inflammation. Whatever the case, you can get slim while you dine in New York this weekend; head to a few of these "healthy" joints to load up on the good stuff.

Obama is here. At least that is the adrenaline-inducing catchphrase being tossed around the lobby of The Pierre. I hold my breath as secret service agents and suited-up black tie security whisk someone passed me. To my left is a ballroom filled with Victoria's Secret pink bags and a band singing a Black Eyed Peas cover. Certainly not the event I am here for, and it doesn't seem like the Obama lackeys are headed there either. As the security cloud saunters into the “To India with Love” Assouline book launch party, I realize it is not B.O. but Ambassador Hardeep Singh Puri and his wife, on their way to join Waris Ahluwalia, Lauren Santo Domingo, Tory Burch, and Natalie Portman to raise spirits, awareness, and funds by leveraging the creative arts to draw attention to the people and culture of India.

Once again, the landscape of nightlife is a'changing. Sometimes, you have to stir up the water to catch a few fish, which is exactly what happened to us. East Village Monday-night favorite Le Souk lost its liquor license, forcing patrons to take their business to Le Souk Harem, but it's the neighborhood that's the real loser. Wandering aimlessly in search of something new and good on Sunday night, we found a new party at White Slab Palace. Places we'd long since wrote off somehow hit the spot if not filled the void. An object lesson on wandering outside your comfort zone.

"They have to be a little thinner than you and I because you always photograph a little fatter." Words of wisdom from Vogue fave Grace Coddington just as the holidays near. But this isn't a reminder from Coddington to put down the fork and do the head-tilt-turned-body-pose for holiday event pics taken by Patrick McMullan; this is Coddington's way of explaining how model anorexia comes to be. "Because they're kids, they take it too far, and they can't regulate their lives, and next thing you know they're anorexic, and it is tragic.” Her remarks come off the ripple-wave that the firing at Ralph Lauren created, a situation Coddington does not chide Lauren for. Instead, she thinks Ralph Lauren is getting too much bad publicity because most models at Ralph Lauren are not super skinny, and this is an isolated incident.

Participating in the annual New York City Marathon is rewarding for both runners and non-runners. For men and women, the feat is inspiring in a time of financial trouble and peaks of national obesity. The race started off promising enough, with Meb Keflezighi's triumphant and touching win as an American runner, pushing New Yorkers encumbered with post-Halloween hangovers to the streets to cheer on the non-professional athletes participating in the great race. "After struggling my whole life with body issues," one runner explained to me, "being a part of the New York marathon makes me feel beautiful ... knowing that I've set my mind to crossing that finish line has changed my life and the way I've experienced self image." A touching admittance from a woman nearing the tail-end of the 26-mile race on the corner of 86th Street in Manhattan. With 7 miles to go at around 1:30pm, the woman was surrounded with comrades, breast cancer survivors, first-time runners, a woman who beat anorexia through marathon training, blind runners, those with Parkinson's disease, and even runners using arm braces to complete the race. It was one of the most inspiring things that a New Yorker could witness, but less than 30 minutes later, we were forced to stop the cheering.

The slutty Mayflower Pilgrim costume over at Ricky's is a whopping $59.99, and the Pirate Hooker getup is $49.99 on sale. Why not save the dough on an outfit you'll wear only once (in public) when you probably look pretty slutty in the first place? MAC agrees, proving all you need for Halloween is a little makeup to theme your sluttiness. Though the references may be vague, explaining to people that the card drawn over your eye makes you a "poker face" is pretty genius. You'll need an extra couple of hours to ready yourself for the night, a steady hand, and a load of tools, but your final outcome as a pop art piece come to life will be worth it. MAC's helpful how-to videos will ensure you'll get it right, even if you cant draw a straight line.

Some people fear hats. They fear them like Ben Barna fears hairy spiders. I can see why -- some hats are very scary. Some just look dumb. But the biggest problem with the whole hat thing is that hats become horrific when people don't own them. Not like they've shoplifted them from Bloomie's, but they don't wear them like the fashion staples they are. They reluctantly smash them down on their uncombed mane to cover up a bad hair day, or deal with the crap weather (today's included). They have a couple of baseball caps, maybe a weird beret of sorts -- none of which really goes with anything they are wearing, and they trudge through their day, convinced they have to scrap fashion for plain function. In a city where the elements are temperamental, hats can be a beauty savior to even the haughtiest of style snobs.

BlackBook senior editor Nick Haramis may be one of the biggest beauty junkies I know. He collects more products then he knows what to do with, and he has tried them all. It often goes overlooked, but gents are often more product-savvy (and in many cases, more picky) than gals. Since Haramis has been around the block (the one with a Sephora and a Keihl's), he would know best. This one is for the boys.

Being a partier used to be as simple as throwing on a clean tee and getting out the door. Now, it's work. The Jane was once our last great hope; it's now all but shuttered. Just when we feel we've found our new home, a place where -- if not everyone knows our name, at least they know our label -- it loses its license, lease, or cool. If we were lazy, we'd advise you to try the Boom Boom Room every single night of the week, but if on top of the world isn't really your scene, here's what's been moving and shaking amongst the movers and shakers this week. We'll be trying them out one by one, consumed with the determination to find our Beatrice Inn incarnate.

You know, just the other day I was hoping that someone would satisfy my need for a highly styled coonskin cap. It's time the trademark topper of fashionistas like Davy Crockett and Daniel Boone got a design update and made a comeback. Imagine my excitement when just this morning I found out that the Kate Gosselin wig was available for purchase. The hair chunk is meant to complete your Jon and Kate Plus 8 Halloween costume, but it could do double time to give your '"slutty frontiersman" costume a fashionable update.
