Don't focus so hard on skinny jeans that you miss the one of the most powerful side effects of eating right and exercising -- being a happy person most of the time. You know, one of those spring-in-their-step types that genuinely loves their life, sleeps like a baby, smiles easily and is filled with boundless energy. Elizabeth Somer's new book, Eat Your Way to Happiness, reminds us the right foods coupled with exercise have a synergistic, immediate effect on your mood and cravings -- critical factors in the size of those jeans.

A registered dietitian and author of Food & Mood, Somer knows her stuff. The book includes 10 easy-to-understand diet secrets peppered with real-life success stories. If you're clueless about healthy eating, but feeling like you've got to do something to shed weight and lose your bad mood, this book is a terrific tool to educate and motivate. If you're a layman-genius in diet and fitness, Somer's assessment tools will help you identify your food and fitness areas that need tweaking.

Here's a sneak peek at a few of Somer's secrets and promises:

Kate Moss recently told WWD that her motto is, "Nothing tastes as good as skinny feels," (and then went on to say that, of course, that's impossible to follow).

Now, as someone who's interested in fashion, I think Moss is fascinating. However, as a woman who feels very strongly that women need healthy role models to look up to, I have issues with her waif look, so this statement got me fairly fired up. Whether you're aspiring to lose weight or not, it's important that you enjoy foods in a healthful way, and Moss' statement is far from showing a healthy attitude toward food.

But then, I got to thinking about her real meaning behind this. I mean, yes, Kate Moss is skinny. But her statement actually brings up a good question that applies to all of us -- are there any foods out there that you're willing to put on a little weight for?

Name: Kara Masucci

Age: 33

Height: 4 feet, 11 inches

Before weight: 222

How I gained it: When I was younger, I ate all the time. Food was always around, and it was yummy. I was active, and I burned it off. But I remember my mom and grandma slapping my hand when I went for the second cupcake and saying things like, "Don't eat that, you're already too big."

As an adult, I enjoyed going out to eat, and I was apathetic because I was already overweight. I just thought, "I'm already big, I might as well have the cheese fondue!" As a Nurse Practitioner, you would think I would know better, but book smarts and street smarts are different. So I resolved myself to just be happy, and I thought I was.

Breaking point: When my daughter was one year old, I started to have some health issues. When I look back at my pictures now, I see how much weight I was carrying, but at the time, I thought I looked the same as when I was a freshman in college. I was overweight, but not "obese."

Have you ever been on a Medifast diet? If you were, you might have been wearing leg warmers at the time -- this diet invention has been around since the 80s.

You won't be grocery shopping much on the Medifast diet because you're required to buy their food. Medifast diet developers say you'll lose weight fast, with a two to five pound weight loss each week on the Medifast 5 & 1 Plan. You eat often on this diet, but in very small doses. The 5 & 1 followers eat five pre-packaged Medifast meals each day, followed by one Lean & Green Meal featuring a lean protein, vegetables and condiments from their approved list of options. With 70 Medifast diet selections, you're not sucking down diet shakes all day. Food choices include chili, stew, soups, oatmeal, scrambled eggs, bars, puddings and a few other mini-meals. But forget that turkey panini with veggie chips for lunch.

Medifast is all about calorie restriction. Depending on which meals -- or, really, bars and shakes -- you choose, you're getting around 800 to 1,000 calories per day. Not much, especially if you're simultaneously inspired to clean the junk off your treadmill and start exercising.

"Someone who is generally going to use Medifast is considerably overweight to begin with and not engaged in any physical activity anyway. The recommendation is for the first two or three weeks on the diet, don't do any exercise at all," advised Constance Brown-Riggs, registered dietitian and spokesperson for the American Dietetic Association. She doesn't think Medifast can support rigorous exercise, but followers can engage in more moderate activities such as walking.

Brown-Riggs has put dozens of clients on the diet over the years with great success, noting it's a good way to jumpstart weight loss for the busy person who doesn't have time or won't take time to consider their food choices.

"It's a good way to get them started. Success breeds success, and once they're able to start losing, it's easier to transition them from Medifast to a regular eating regimen," Brown-Riggs said.

Nutritionally-speaking, meals do combine protein and carbs, so you can allegedly lose weight and retain lean muscle. They also have designed a meal plan for people with Type 2 diabetes. This diet isn't cheap, a four-week package of Medifast meals costs about $300. Comparatively, Nutrisystem costs about $350 a month, the Cookie Diet is about $240 and the high-protein Atkins diet sells a variety of a la carte bars, shakes and cuisine. The cost of the Jenny Craig diet depends on menu items ordered. Jenny Craig says their clients spend $1 more a day than the average American spends on food, but this ballpark cost remains a mystery until you start ordering.

Instead of choosing diets that require pre-packaged meals, try shopping the perimeter of the grocery store -- where the produce, lean meats and dairy are located -- and writing down all of your meals in a $5 food journal.

First there was a scale that uploads you current weight to your computer. Then there was the phenomenon of tweeting what you eat. Now technologically-savvy slimmers can take it a step further by tweeting their weight with this high-tech WiFi scale -- it automatically updates your latest weigh-in on twitter for all your followers to see. But it does more than that -- it also calculates your BMI and body fat, all for the price of $159.

I know what you're thinking: Why on earth would anyone want to post their weight on twitter? Withings, the French company behind this product, thinks that tweeting your weight will provide a you with a much-needed kick in the butt, "further motivating them by sharing their progress with followers," reported the LA Times. In other words, they want to shame you into sticking to your diet. It's a good concept in theory, but I have my doubts that this kind of 'shame' diet actually works.

What's your take? Would having your weight published on twitter motivate you or embarrass you horribly?

The Zone Diet, devised by Barry Sears, M.D., and introduced in 1995, gained popularity through celebrity dieters like Jennifer Aniston, Demi Moore and Madonna.

Like other weight-loss plans, the Zone Diet encourages dieters to cut calories, especially those from carbohydrates and unhealthy fats. It encourages people looking to lose weight to eat lots of lean meats and other foods filled with healthy omega-3 fatty acids as well as fiber-rich vegetables and fruits. To keep their blood-sugar levels stable and fend off hunger pangs, those on the plan eat five small meals a day.

Unlike some diets, the Zone Diet doesn't force people to buy certain foods, which can help cut down on the costs that sometimes accompany these plans. There are, however, a line of Zone Diet supplements. People who choose to eat them should be warned that they can be expensive.

Sounds perfect, right? Not so fast.

The diet discourages dairy consumption, which can keep those on the Zone Diet from getting several essential vitamins and minerals like Vitamin D, Vitamin E and calcium. Another common complaint is that the low-carb plan leaves dieters too tired to exercise. Coffee and soda intake can get tricky on the plan, too, because caffeine, which causes insulin levels to spike, is considered a no-no.

Others have a hard time understanding the 40 percent carbohydrates, 30 percent protein and 30 percent fat (40-30-30) ratio that Dr. Sears says will make your metabolism function best. These restrictions can be especially problematic when you're dining out. Dieters are also required to eat within one hour of waking and, roughly, every two to three hours after.

Additionally, Zone Diet creators claim -- despite a lack of evidence -- that those who follow the plan will decrease their risk of cancer, heart disease and other conditions while improving athletic performance.

If you have decided to lose weight, one of your best bets is a healthy, low-fat diet, paired with exercising several times a week. That's Fit has Diet and Weight Loss tips to help.

Chromium, also called Chromium Picolinate, is a weight-loss supplement. Chromium is a naturally occurring mineral found in meat, poultry, fish and whole grains, and when combined with picolinic acid, has anecdotally been believed to help weight loss by helping in reducing body fat and increasing lean muscle. Chromium picolinate has also been linked to having positive effect on how the body processes glucose and been rumored to manage type 2 diabetes.

But while it's mostly agreed that chromium picolinate weight-loss supplements aren't generally harmful, they're not thought to carry much benefit either -- i.e. they probably won't help you lose any pounds.

According to Health Service at Columbia University, there is no evidence to prove that chromium affects weight loss.

Hank Lukaski, Research Leader at the US Department of Agriculture Human Nutrition Research Center insists, "Chromium picolinate has no effect on building muscle, reducing body fat, changing body composition, decreasing weight or increasing strength."

Officials at Harvard Medical School advocate natural chromium consumption through a healthy diet rich in whole grains, nuts, broccoli and green beans, which contain the mineral, but do not recommend chromium supplements without a doctor's consent.

What's more, Science Daily reports that there may be an increased cancer risk to those who regularly took the chromium.

Chromium picolinate supplements are taken on a daily basis before working out. Alternatively, pure chromium supplements can be ingested. Chromium and chromium picolinate supplements are available through various online dealers for approximately $10 for 250 tablets.

Name: Catherine Walker Hart

Age: 30

Height: 5 feet, 7 inches

Before weight: 168

How I gained it: Food addiction and overeating runs on one side of my family -- fast eating runs on the other side. I got both! I've always loved to eat and have always been a fast eater. Eating way past my full point was a daily occurrence in my life.

Growing up, I was very active and had a pretty decent metabolism, so I used to get away with eating too much. After I got married in 2006, I was no longer as active as I had been and my overeating started to catch up with me. My husband and I also became the "king and queen of takeout." When you eat most of your meals from restaurants, you don't have control of what goes into them, and the portions are larger than one person needs. I also was a bit of a carb addict, easily eating four to five times the appropriate amount of carbs in my meals. My husband and I also developed an ice cream habit. We could go through an entire pint on a nightly basis.

The more weight I put on, the more uncomfortable I felt, which only led to more overeating. And I was not burning off any of it! I tried several attempts at the gym, but I always felt lethargic and unmotivated. Eventually, I gave up.

Breaking Point: I started to notice that I could no longer cleverly hide my weight gain with baggier clothes. I have a small frame, so there was a window of time when I could hide extra pounds, but I was gaining weight beyond that window. The depression about my weight really kicked in when I had to buy a new pair of jeans in a larger size for the third time.

I became incredibly self-conscious about my weight and felt very uncomfortable in my own skin. I liked to think of myself as a strong, active person, and there I was carrying around an extra 35 pounds. I felt like I wasn't myself.

My weight was increasing, and I wasn't having any success changing to a healthier diet. In fact, I don't think I even understood what it meant to eat healthier. My grandfather had been a lean, strong, active athlete his entire life, but his addictive eating cut his life short. I knew in my heart that I had his genes and that if I didn't change my lifestyle now, I could be on the road to obesity with serious health consequences. I needed to kick it in the butt! I decided right then and there that "being heavy" was just a phase: I would not be a heavy person for the rest of my life.

The Mayo Clinic Diet is a fad diet purported to help people lose 50 to 55 pounds during a 10-week span. It has no connection to the respected Mayo Clinic, a top research hospital, in Minnesota.

The basic premise of the diet is that dieters should ban all complex carbohydrates, but can eat as much protein and fat as they want. One of the "rules" of the diet even states, "At any meal you may eat until you are full -- until you can't eat any more."

Experts agree that a diet based on unbalanced nutrition and limited food choices, like the one recommended in the Mayo Clinic Diet, can be unhealthy. Plus, the boredom associated with eating the same foods over and over can prompt a return to old eating habits once someone goes off the diet.

The quick weight loss associated with the plan is also unhealthy. A better option than the Mayo Clinic Diet is the Mayo Clinic Healthy Weight Pyramid, a lifestyle plan that includes a variety of healthy foods and daily exercise -- and is actually associated with the Mayo Clinic. It offers personalized menus, shopping lists, meal plans, results charts and dining-out tips.

Xenical is a prescription drug designed to help significantly overweight people lose weight. It is a version of Alli, the only diet pill that is approved by the FDA.

According to the manufacturers, Xenical is different from other diet pills because instead of suppressing your appetite or speeding up your metabolism, it blocks about one-third of the fat you eat from being digested. The undigested fat cannot be broken down and is eliminated through your bowel movements.

However, Xenical is not a magic pill.

"Xenical is a weight-loss drug that can have significant side effects and in blocking the absorption of fat to encourage weight loss, may also block the absorption of important vitamins, minerals and healthful fats required by the body," says Marissa Lippert, RD, of Nutrition Counseling & Communications. "Weight-loss drugs are temporary fixes, rather than lasting solutions. It's important to remember that in order to healthfully lose weight and sustain it, fresh food in the appropriate portion sizes should be the primary focus."

The American Heart Association agrees and recommends reduced-calorie diets that typically allow for no more than 30 percent of your daily caloric intake to come from fat.

Possible side effects include uncontrollable bowel movements, gas and oily discharge.

If you think Xenical may be right for you, speak to your doctor.

At That's Fit, we've got great food ideas, exercise plans and more to help you lose weight.

Love handles refer to fat deposited on the sides of the waist. These unsightly bulges are also known as a spare tire or a muffin top, which occurs when excess fat hangs over a person's waistband.

Most people agree that having excess fat around the midsection is undesirable. Research shows that abdominal fat leads to higher risks of heart disease, diabetes and even certain types of cancers. But how do you go about getting rid of love handles?

One way to effectively eliminate love handles is to lose weight by following a reduced-calorie diet and by consistently doing cardiovascular exercise.

As you begin your diet and exercise program, you can disguise your love handles by wearing clothes that fit properly. Avoid too-tight clothing, low-rise jeans and midriff-baring shirts. Opt for pants that go around your natural waist and for women, skirts and dresses that sit at your natural waist.

The trademarks of yo-yo dieting -- overeating, followed by deprivation in guilty repentance -- may seem like something a doctor would have the self-control and training to be above, but Michelle May, M.D., former yo-yo dieter and author of the new book "Eat What You Love, Love What You Eat," explains that "health care professionals are people too," and that the restrictions of diets -- not the dieters -- are to blame for failed weight-loss plans.

The reason? In her book, she explains that the very basics of dieting -- the counting, planning and constant need to think and plan your eating based off of someone else's rules (often "before you're even out of bed!") is tiring. So much so, that any good aspect of the diet is essentially canceled out by the end result: "This constant effort and vigilance may wear you out and cause you to return to overeating to escape." Once Dr. May ditched diets, and adopted long-term successful strategies she describes below, the weight came off.

That's Fit: What do you think was most effective in helping you achieve a healthy weight?

Dr. Michelle May: I had to pay attention not just to what and how much I was eating, but why I was eating in the first place. I didn't have any deep, dark emotional issues, but I had certainly learned to comfort and entertain myself with food. Even when I was on a diet and following the rules about what to eat, I was still eating when I was bored, stressed or tired. When I felt too deprived of the foods I loved, I'd go off my diet. Nothing had fundamentally changed about my relationship with food so I just went back to overeating my favorites. This is what I called my eat-repent-repeat cycle.

I've since worked with thousands of people who are doing exactly the same thing, and the reason is that with yo-yo [dieting you don't] have any middle ground -- you are either on your diet or off. I kicked yo-yo dieting by changing the paradigm completely from a yo-yo to a pendulum. There is still the possibility of extremes but as you give overeating and dieting less of your energy, the pendulum settles into a smaller arc in the middle where you have the flexibility and the mindfulness to nourish your mind, body, heart and soul.

This just in: Candy will still be available after Halloween! Here are tips to help you avoid being "tricked" by candy and to let you indulge in a treat that won't wreak havoc on your good habits.

1. Give the treat of healthier snacks.
The grocery shelves are crammed with 100-calorie snack packs that are healthier options than candy. Snacks like pretzels, roasted nuts and baked chips and crackers are better options than some candies, and if you indulge in a pack, too, you can do it guilt-free.

2. Recognize your intent.
"Sometimes it's not the candy we want at all; we are just craving a particular feeling, like comfort or excitement," said Pam Wood, a Weight Watchers meeting leader in Austin, Texas. "We need to ask ourselves, 'What is it that I really want to satisfy: the craving for the candy or the craving to feel fabulous?'" If it's the latter, she advises that you say "no" to the candy and determine the best way to satisfy your true desires. If it is candy, go ahead and have a small piece to satisfy the craving.

SlimQuick is a weight-loss product that claims to be the first fat-burning aid created especially for the fat-storage issues of a woman's body. The weight-loss formula uses vitamin and herb complexes to "overcome the physiological and hormonal barriers" of losing fat."

Reviews of SlimQuick are mixed. On the positive side, the SlimQuick program advocates an exercise program to accompany the use of the product. One testimonial on the SlimQuick web site said, "I was faithful to the diet and exercise program that was outlined. I have never had such quick and excellent results in any diet program."

But there are dissenters out there, too. "Products like SlimQuick perpetuate the growing trend of misinformation under the guise of 'science.' At best, it offers false promises of health and fitness in a bottle," said Melissa Urban, owner of CrossFit 603. "At worst, it could be dangerous to your health."
