Stepping on the scale sucks. So I completely understand why Janet Jackson says she refuses to ever weigh herself again. 

It's like a cruel carnival game as you wait for those flickering digits to reveal just how much damage last night's carb fest caused.

It must be particularly hard for the pop star, who has so memorably yo-yo'd in front of the world.

She recently slimmed down with the help of Nutrisystem, but what Janet doesn't realize is that she already has the best weight loss tool she'll ever need - the "OMG! I-wish-I -had never left-the-house-that-day" photo! (see below).

Which do you think is more likely to happen by the year 2030: We're all traveling by jet pack, or 42 percent of us are obese? I WANT the first one to be true. (What's taking them so long with those jet packs, anyway?) But unfortunately, it really does look like 42 percent of us will be obese in about 20 years -- so says a study for the Centers for Disease Control.

Right now about 34 percent of us are obese. And I'm not at all surprised to hear that we're just going to keep rolling along like this. Here's why.

Dance walking! It's the hottest new fitness craze! Why are you walking down the sidewalk like a normal person? You could be dancing, YEAH. Put on your headphones and waggle your ass to the irresistible beat. It's what everyone in New York City is doing.

Ha ha, no. We're not doing that. But this guy is. TV reporter fitness experty guy (or something) Ben Aaron is trying to get this party started on the streets. After seeing a real dance walker strutting his stuff down 5th Avenue, Ben got all inspired and decided dance walking needed to become a thing.

So he tried it himself. And then he got other people to dance walk with him. None of these people look the least bit silly, by the way. Not at all.

Have you ever envied Jennifer Aniston's super-buff figure? If you say no, then I'm going to have to assume you're either lying or you're just hopelessly devoted to Team Angelina and refuse to shed any sort of positive light on Jen. Because it's pretty hard to argue that she's got one of the most rockin' bodies in Hollywood -- hands down.

So many of us have always wondered how she manages to stay so slim and trim, without the slightest hint of a lump, bump, or inconvenient bulge. She has to be drinking some sort of magic potion right? Well, it turns out that her method for staying in perfect shape is one that many of us have access to right in our hometowns, and a lot of us are probably already doing it. So -- how do we make our bodies look just as buff as Jen's?

Wow. Reese Witherspoon is looking good these days. Of course, that's not to say that she's ever really looked bad, but you can tell that she's firmed up a bit more and is in the best shape of her life. I mean -- have you seen her amazing legs? I'm totally jealous.

Reese had to get into tip-top shape for her new movie, This Means War. Her trainer, Michael George, says that she owes her hot bod to a healthy eating plan and to going hiking while carrying light dumbbells, as opposed to major sweat sessions in the gym. In addition to regular hikes, Reese and Michael would also stop in the woods and do yoga poses to cool down. Um -- for real? Does that mean if I walk up and down the big hill in my neighborhood while carrying soup cans and then do a little downward dog in my front yard, I'll wind up with a physique like Reese's?

Somehow I'm not so sure.

Want to know how you can eat more and weigh less? Don't we all! The Great and Powerful Dr. Oz will reveal how it's done on his show tomorrow. And I'm dying to find out what his big secret is. I can almost hear the other shoe dropping. What if it's really just "Eat more of this ridiculous raspberry keytone supplement" nonsense?

But but no -- I think this time it's going to be about actual food. Tomorrow's show is about smart snacking. Hope springs eternal! Also, Top Chef judged Gail Simmons will be on hand, hopefully making sure Dr. Oz's super snacks actually taste good.

We knew Michelle Obama had gorgeous sculpted arms of steel, but even that knowledge didn't quite prepare us for her performance on the Ellen DeGeneres Show. Ellen (who herself is surprisingly buff) challenged her to a push-up contest, and the First Lady wowed the audience by pounding out 25 real push-ups one after the other. And, she would have kept going if Ellen hadn't stopped her!

So what exactly do I mean by "real"?

It's been 25 days since the first of the year when we all vowed to eat right, exercise more, and make 2012 our year to rock a bikini ... or at least appear publicly in a swimsuit of some sort. How are you doing on your resolutions?

Judging from attendance at my gym, I'd say many of us are still going strong. But I know that as the chocolates of Valentine's Day start springing up, and the weeks pass by, we often leave our good intentions in the dust ... covered by a heap of chocolate wrappers. So how to prevent what feels like the inevitable from happening?
