They say money can’t buy you happiness but a new study shows that for some overweight people, it just might. The new study from the Mayo Clinic found that people are motivated to lose weight when money is involved. When it comes to slimming down, financial incentives are king. For some reason, we are willing to gamble with our health, but not our money. It's pretty sad that we are more afraid of being broke than we are of being dead.

And for biggest transformation of a reality TV star ... the award should definitely go to Snooki. I can't think of any other celebrity in recent time who has undergone such a metamorphosis, or at least a positive one anyway.

From her Jersey Shore days falling down and peeing on herself to becoming an admirable mother, she's really made changes for the better in her life. Now, on top of it all, she has also completely changed her body, losing an amazing 42 pounds since giving birth to her son, Lorenzo, last August.

She's rocking a bikini on the cover of Us Weekly, and she has never looked better. At just 4-foot-9, the famous Guidette now weighs 102 pounds. That puts her BMI at a healthy 22.1, and it's clearly a weight that suits her. Who would have ever thought Snooki would be an inspiration in so many ways?

So, of course, now what we all want to know is: How did she do it?

Have you heard of the latest trend in eating disorders? It is male anorexia, nicknamed “manorexia”. Honestly, it’s not actually anything new. It's just that it's been brought into the spotlight by the media recently. And it's about time. Maybe now, anorexia will get the attention it deserves and people will start to fully understand this is a serious problem. It’s not just a teen girl trying to fit into a size 0; it can affect anyone, even men.

The name might sound funny but the disorder can easily be fatal. People seem to think that if you add -orexia to anything these days and it simply suggest that people are over indulging in an activity. But manorexia is a devastating disease and the repercussions include the possibility of death.

2012 was a challenging year for Jennie Garth, but she has a lot to be proud about. She got through a divorce with former husband Peter Facinelli and is building a new life with her daughters. Garth also lost 30 pounds -- but that accomplishment wasn't about getting skinny. She got healthier this year.

Jennie spent years yo-yo dieting. In this month's Health magazine, she says, "My biggest regret is putting my body through fad diets: Atkins, cleanses, the hCG diet. I lost like 18 pounds, but it came right back." Even worse was her "horrifying" three or four days fasting with colonics. In 2012, she tried a very healthy new strategy.

My highest non-pregnancy weight was around a year and a half after my first son was born. I was sick of feeling uncomfortable in my own skin -- and sneakily relying on maternity-waisted sweatpants when I was at home -- but I had developed some very bad eating habits. Well, it wasn't so much habits, plural, as one major diet-sabotaging routine: every evening, after my child went to bed for the night, I collapsed on the couch in front of the television and mainlined whatever junk food struck my fancy.

I knew it wasn't healthy, but the entire comforting ritual had become my reward for making it through another day. Those precious few hours between my kid's bedtime and my own represented the one time a day I was allowed to be as selfish as I wanted, and what I wanted was to completely unplug … and treat myself. With, say, an entire pint of Ben & Jerry's Mint Chocolate Cookie ice cream.

What's the number-one reason why the Army rejects recruits? It's not for any misdeed, exactly. It's because of obesity. In the first 10 months of this year alone, the Army had to reject 1,625 soldiers because they couldn't meet the fitness standards. A whole 5.3 percent of the troops (86,186 people) were declared overweight or obese in 2010. And military leaders have been warning that Americans' battle of the waistline may be an issue of national security.

I can't imagine how humiliating it would feel to be rejected from the Army because of your weight. That must feel terrible. Is there really a health crisis in the Army, or is this more about budget cuts? If it's both, what can people do about it?

Women and weight. We go together sort of like Jekyll and Hyde in the way that we love, hate, can't live without each other. As a lady, I'm always aware of my weight and it's so frustrating. I don't want to worry about the numbers on the scale, but try as I may to stop, I still do.

Even if I didn't want to, I could still count calories faster than I could ever recite the ABC's. But my problem with working out is that it's a lifestyle. You can't work out for a week, take three months off, work out for a day (not like I'm speaking from personal experience or anything ... but, uh). It's not a phase. And that's totally why maintaining my weight is such a challenge for me.

Why is it every time I reach behind me in the car to hand my children a toy/drink/video game, I end up pulling a muscle? I used to be limber, stretchy, "bendy," but now I can barely walk to the bathroom without something cracking or popping. Listen, the only thing that should be snapping, crackling, or popping in the morning is my children's cereal!

Which is why I invited Rob Sulaver, trainer to the stars and founder of Bandana Training, to come on The Jenny Isenman Show.

Watch after the jump for a (quick) kick-ass morning stretch to get you through the day -- without having to pop anything back into place!
