Wynonna Judd is singing the weight loss blues ... or rather the reds, blues, golds and greens of the alli© logo. She's signed on as spokesperson for the weight loss drug.

Judd is part of a long-list of celebs who have lent their names and faces to weight loss products. Jenny McCarthy once touted Weight Watchers, and Phylicia Rashad is the latest celeb speaking for Jenny Craig. Regarding alli, Judd said "I've considered every diet under the sun, but so many of them wanted me to be something I'm not and do things I knew were not healthy for me. Then I discovered alli. With the alli program, I'm learning how to make and maintain healthier lifestyle choices. It keeps me honest with myself and allows me to set realistic goals."

That's great, Wynonna. But I've got one question. Why do you need alli to do all that? You can make healthier choices and set realistic goals without a pill.

The old weight-loss-in-a-pill wish. I think most of us who have a few pounds to lose have wished it could be that easy from time to time. And when you watch the commercials on TV, they certainly make it seem like magic. Think about it -- one second an overweight person is pictured and the next second -- BAM! -- that very same person is thin and somehow tanner and more smiley. What a miracle, right? Not only do the pills help you lose weight, they must also make you tanner, happier and give you better hair. Who wouldn't want some of that magic?

Unfortunately, it's not that easy. Weight loss requires work and a commitment to a healthier lifestyle. And, while some weight loss pills undoubtedly do help, there are associated risks. Jacki recently told us about the risks with some of the more popular weight-loss medications, most of which are available by prescription only. But a lot of the lesser known medications can be risky, too.

The FDA listed 28 weight loss products that contain hidden -- and potentially harmful -- ingredients. No, thank you. Check out the gallery for more tried and true ways to shed pounds.

When a food item becomes a health trend, it starts popping up everywhere -- from energy drinks to sodas to diet pills, sometimes even in shampoo. Acai is one of the more recent nutrition trends ... but is it worth all of the fuss?

According to Dr. Mehmet Oz, acai berries are rich in antioxidants and are a very nutritious food. However, Dr. Oz states that acai is as good as any other healthful food, not any better. One reporter and her husband decided to try out the acai diet -- he took capsules and she used a powdered drink mix. Not only was it expensive, the drink was gritty, and neither saw any weight loss results. And the cleansing drink that came with the acai diet was completely gag-inducing.

The lesson here is to not go overboard. When nutrition news hits the media, the marketing folks clamor on board and try to sell as many products as possible based on very limited science. Acai is a great food to incorporate into your diet but if you're expecting it to help you magically drop excess pounds, cure disease and unclog your kitchen sink, you're going to be sorely disappointed.

If you have a slice of delicious cake, would you think it's OK to chow down the whole cake in one sitting? Of course not. Common sense would tell you that a whole cake is just too much. Unfortunately, when it comes to health advice, not everybody uses common sense.

I recently wrote a post about the benefits vitamin D can have on heart health. That's only one of the perks of vitamin D that has been in the press lately. Now many people -- buying into the vitamin D kick hook, line and sinker -- are buying high-dosage vitamin D supplements from pharmacies and health food stores.

There is no science that says high doses of vitamin D are necessary. And why waste your money on a supplement when vitamin D is so readily available from other sources? Sunlight is your best source, but again, it's important to be reasonable. You don't want to spend too much time in the sun without the protection of sunblock, so a few short 10-15 minute walks outside each week will do. Vitamin D is also available in fortified foods such as milk, some cereals, and orange juice, and it's naturally found in salmon and other oil-rich fish.

Skyrocketing childhood obesity rates have an unwanted side effect -- more kids are being put on prescription medications to combat related chronic diseases.

A recent study revealed there have been surges in prescriptions for children with diabetes and asthma as well as smaller increases in high blood pressure and high cholesterol medications. To varying degrees, obesity can play a role in all of those conditions. While some of the medication increase can be attributed to modified guidelines, the rise is concerning.

If your child is overweight, there are many positive, supportive ways you can help. AOL Health has other suggestions for battling childhood obesity.

I've said it before: When it comes to weight loss, there are no quick fixes -- well, at least none that are healthy and effective in the long run. These days, there's a lot of buzz about one quick weight loss plan. Dubbed a miracle pill, this once-daily medication has been shown to shrink study participants two clothing sizes in six months, more effective than any other pill on the market.

Here's the scary part: Originally developed to treat Parkinson's and Alzheimer's, tesofensine alters the chemicals in the brain that control appetite and hunger. The side effects include diarrhea, nausea, constipation, insomnia and mood changes. Yikes!

Taking 'the pill' is a common practice among young women these days. But for how long? Studies show that the amount of women who take oral contraceptives is declining for one very good reason: They're afraid it will cause them to gain weight. But is this a legitimate concern, or is it just an urban myth?

Chalk this one up to idle gossip, according to this article from The Telegraph. Scottish Professor Anna Glasier said: "We need to emphasize that [oral contraceptives] don't impair fertility, and the majority of them don't affect weight." All the same, many women do report weight gain and other changes when they go on the pill, but this is more likely due to lifestyle changes, according to Dietitian Juliette Kellow.

Sorry girls, guess you can't blame that extra love handle on the pill -- time to get to the gym.

Weight loss in a pill. It's the weight loss equivalent of the fountain of youth ... and just as elusive.

The major pharmaceutical company, Merck, has been in clinical trials for an anti-obesity drug called taranabant. But Merck recently announced that it was halting development of taranabant because of side effects. In certain doses, the drug was effective in helping patients lose significant amounts of weight. But there was an adverse side effect ... those taking the drug had an increased risk of psychiatric events. It's not clear from the article what exact psychiatric events were being experienced.

While the side effects of this pill are obviously extreme, it's not the first attempt at a weight loss pill that comes up short. While it would be nice to cure obesity with a quick fix, the old tried and true method of eating right and being more active is still the best bet.

I recently interviewed Erin Andrews, the very pretty and fit sideline reporter for ESPN. While we spoke, Erin told me her secret to staying really fit and trim. After gaining 10 pounds "eating like a guy" with the College GameDay crew, Erin was mortified to see her much larger bum showcased all over the internet.

I was like "Oh my God!" she said. "What happened to my butt?!!!" And with that ... Erin hired a trainer, changed the way she was eating and made sure she didn't try to keep up with her male coworkers at the bar. Can you imagine having the world document each and every pound you gained each day of your life?

I tend to think there's no real substitute for hard work, which makes me think that the new pill that might one day allow us to get fit while slouching on the couch or achieve elite athletic status without dripping a drop of sweat is just not all it's cracked up to be. I know, mice are running their little hearts out on treadmills as I write so that we won't ever need to, but still, I don't buy it. And I won't buy it, even if and when it becomes mainstreamed into our obese world.

If you haven't been tuning in to the news on this medical development, here's what's happening: U.S. researchers have developed two possible pills that build muscle, stamina, even burn fat. In tests, mice were able to run 44% further with a boost from these concoctions, suggesting humans may be able to do the same without prior training. The whole concept is controversial due to fears the pill could be misused in sports. Let's face it, when drugs are used to achieve something good, there's always a side effect that's not so good, whether it's unfair athletic gain or a long list of possible health complications.

The initial good researchers were hoping to achieve with the two drugs (labeled AICAR and GW1516) is the improvement of health for those with muscle-wasting diseases and those with diseases like diabetes, in need of physical activity. Now that it's clear anyone can benefit, well, anyone will likely be able to benefit. Says one researcher: "If you like exercise, you like the idea of getting 'more bang for your buck'," And: "If you don't like exercise, you love the idea of getting the benefits from a pill."

Q. Fitz, For about a year now, I've been doing exercises for my obliques. I've done them about three or four times each week and have done a variety of different exercises each workout. I'm also a naturally thin person who recently lost 10 pounds (so I'm really thin now) and I still have those awful love handles! How do I get rid of them? Emily

A. Ugh Emily! This is a question I've answered before, but since it's such a tremendous source of frustration for so many...I believe the topic of love handles is worth visiting again. You're actually the perfect example of how annoying they can be. You are a trim person who does a variety of abdominal exercises frequently. Most folks would believe that would be enough. Unfortunately for some people, it is not.

Love handles often have to do less with abdominal muscles and more with body type. For example. I'm a pretty trim chic, but when I have gained weight...it's all gone to my boobs, belly and thighs. In fact, I used to be 40 pounds heavier than I am today, but I've never had love handles. Some people get it all in their hips. Even if they achieve their ideal weight, some of those people are still stuck with dreaded 'saddlebags'. Your issue is the same. Great fitness. Lean body. One or two annoying pockets of fat.

It turns out that the price of a sugar pill may affect how well it performs on pain. Most people don't go shopping for placebo medication, but this new study does suggest one interesting conclusion. The perception of your meds being expensive treatments or "discount" pills will affect how your body reacts to the medication.

The placebo effect is an amazing thing to study. But who would have thought price would come into play as well? One reason researchers think this has such a profound result is that our bodies produce natural painkillers anyway. Apparently if we believe we're getting a better product, then we'll respond that way!

In fact, a Duke University clinical professor says it can help upwards of 50 percent for some people! This is in regards to migraines, but it's amazing to think we can materialize our own recovery like that. So should you be ditching discount drugs altogether? Obviously it's a matter of perspective, but real drugs are drugs. So listen to your doctor because in the end medical professionals will point you in the right direction.

Have you ever seen the movie Fantastic Voyage? In this old 1966 flick, a submarine containing a team of scientists is shrunken to a size so small that they can navigate the blood stream in a human being. Imagine being able to get a view like that by swallowing a camera the size of a pill. That's exactly what researchers are describing with a new design for an even easier endoscope.

Pill camera are not new, but traditionally they are so uncomfortable that patients need to be sedated beforehand. This new design allows someone to swallow the camera and beam pictures back out of the mouth so easily that it could be done in a shopping mall. That's exactly how one professor described it.

Not only is it easier to engulf, but the procedure is cheaper too. This is good news, because esophageal cancer is rapidly growing in the US. Survival rates of progressed conditions are not very good, which stems from the difficulty in diagnosing it early enough. It all goes back to patients not being easily screened for Barrett's esophagus, the condition preceding cancer. Hopefully now they can rapidly deploy this new mechanism to catch cases quicker. Who knows, maybe treatment via this little pill is next!

I've heard it before: The pill protects against ovarian cancer. And here the news presents itself again, this time in the form of a study revealing birth control pills can protect women from this disease even decades after they stop taking it.

British researchers have found that women taking the pill for 15 years cut their chances of developing ovarian cancer by half. The risk remained low more than 30 years later, although protection did weaken over time, according to study findings that were published Friday in The Lancet.

Overall, this is good news. Not only do you get to prevent pregnancy, you get to prevent ovarian cancer at the same time (long-term protection against endometrial cancer is a bonus too). But there's a downside to this hopeful news: The pill also slightly increases the chances of breast and cervical cancer. The risk seems to disappear once a woman stops taking the oral contraceptive but still, the gamble remains for as long as the medication is used.

Martha mentioned recently the potential that one day, we may need only a pill to maintain a healthy weight and live a long life. Wouldn't that be grand? Maybe. But I'm here to tell you we're a long way off from such a dream. That magic pill, likely to house the supplement Resveratrol, isn't quite ready for human use.

Resveratrol, a natural substance that comes from the skin of red grapes, has been shown in studies to keep mice thin, boost their energy, and extend their lives, all while protecting them from the dangers of an unhealthy diet. Resveratrol also helped mice maintain their motor skills as they aged. There have been no similar studies in humans.

Don't pop that cork and conduct your own studies just yet. You'd have to down 1,000 bottles of red wine to consume as much Resveratrol as each mouse was given. Until further notice, just stick with a handful of red grapes. The fiber, vitamin B, and manganese packed into this juicy fruit is good enough for now.
