CORVALLIS, Ore. An Oregon State University researcher says weight loss supplements don't work.

Melinda Manore, professor of nutrition and exercise sciences at the university, reviewed the evidence surrounding hundreds of weight loss supplements and found no credible evidence that any single product results in significant weight loss. Many have detrimental health benefits, she reported.

The weight loss supplement industry rakes in about $2.4 billion a year in the United States.

The study, "Dietary Supplements for Improving Body Composition and Reducing Body Weight: Where is the evidence?" is published online in the International Journal of Sport Nutrition and Exercise Metabolism.

She learned that a few products, including green tea, fiber and low-fat dairy supplements, can have a modest weight loss benefit of 3-4 pounds. But they were tested as part of reduced calorie diets.

For most people, unless you alter your diet and get daily exercise, no supplement is going to have a big impact, Manore said.

The supplements Manor examined fell into four categories:

Many products had no randomized clinical trials to hold up the claims. Many don't include exercise as part of the regimen.

No regimen for weight loss has replaced eating a balanced diet and regular exercise, she said.

The Kardashian sisters are being sued over claims and endorsements they made about the QuickTrim weight-loss product line.

The class-action lawsuit was filed in the Southern District of New York, said The New York Daily News. Four plaintiffs allege that reality sisters Kim, Kourtney, and Khloe made unsubstantiated, false and misleading claims in advertisements, interviews, and tweets, touting QuickTrims efficacy.

A recent U.S. Food and Drug Administration (FDA) evaluation revealed that the key ingredient in QuickTrim is caffeine.

Attorneys for the plaintiffs, who are based in New York, California, and Florida, criticized the ubiquitous sisters and QuickTrims manufacturer, Windmill Health Products, for perpetuating false claims that QuickTrims line curbs cravings, promotes weight loss, and burns calories. The sisters have been identified with the brand since 2009 and are known to mention QuickTrim products during television and magazine interviews, telling their fans that they use QuickTrim products to lose weight and maintain that weight loss, said The Daily News.

In January 2010, Kim Kardashian told Ok! magazine that she used a number of QuickTrim products to quickly drop 15 pounds in a few short weeks, said USNews. Both Khloe and Kim have boasted 15-pound weight losses with QuickTrim, said ABC News.

The $5 million class-action lawsuit, filed Thursday in federal court in New York, alleges that no competent and reliable scientific evidence supporting any of these claims exists, said US News. As a matter-of-fact, The FDA has in fact determined that there are inadequate data to establish the general recognition of the safety and effectiveness of caffeine for the specified use of weight control, the lawsuit states.

The lawsuit also blasts the products advertising, which encourages consumers to utilize the full range of QuickTrims product line, which includes pills and so-called cleanses for increased efficacy, but with no evidence supporting these conclusions, said The Daily News. The line also includes powdered drink mixes and was created to detoxify and clean the body by removing extra water weight and bloating, due mostly to the laxatives in the products, according to the manufacturer, said USNews.

QuickTrim products are widely available nationwide at more than 25,000 retail chains, including Wal-Mart, Walgreens, CVS, and GNC. Quick-Trim ins based in New Jersey said ABC News. Not only is there no scientific evidence to back up QuickTrims claims, recent research suggests cleansing products such as what QuickTrim touts are ineffective and dangerous, said US News. A study published last year in the Journal of Family Practice reviewed 20 case studies reported over 10 years and found that colon cleanses can lead to a number of issues from mild cramping to kidney failure, said USNews. These products tout benefits that dont exist, the study authors said.

This is not the first time the Kardashians have been involved in litigation over their marketing endorsements, said The Vancouver Sun. Endorsement deals accounted for a huge chunk of the Kardashians net worth at a whopping $65 million in 2010, according to industry trade magazine The Hollywood Reporter. Kim, 31, is one of the highest paid U.S. reality stars with 2010 earnings estimated at about $6 million for her reality show; clothing line; and many fitness, beauty, and other endorsements.

Last year, the sisters and their mother, Kris Jenner, were involved in a $75 million debit card endorsement lawsuit involving the Kardashian Kard, over allegations that the card charged prohibitive consumer fees, said The Vancouver Sun.

The question: Whats the best breakfast cereal for weight loss?

The answer: Im afraid there is no breakfast cereal specifically designed for weight loss. Compared with other breakfast choices, most cereals are relatively low in calories and low in fat. But its not all about calories. Some low calorie breakfast cereals (e.g. Special K, Rice Krispies, Puffed Wheat) are made from refined grains that are quickly digested. In other words, starting your day with a bowl of refined breakfast cereal could cause you to feel hungry midmorning and overly hungry by lunch time. Both are recipes for overeating.

The healthiest breakfast cereal is made from whole grains and is high in fibre and low in added sugar. Choose a cereal that lists whole wheat, whole oats, whole rye or whole brown rice as the first ingredient. One-hundred-per-cent bran cereals arent truly whole grain cereals, but you can consider them as such since they are a concentrated source of bran thats missing from refined grains. And because fibre slows down the rate at which food leaves your stomach, it helps you feel full longer after breakfast.

Look for cereals that have no more than six grams of sugar for each serving. Theres one exception to this rule: Cereals with dried fruit such as raisins, blueberries and cranberries will have more and thats okay. Dried fruit adds more fibre to cereal, which is a good thing.

Now that youve chosen a nutritious cereal, keeping your portion size in check will help you lose weight. Of course, thats provided youre following a calorie-reduced diet designed for weight loss. Read the serving size information on nutrition labels. I encourage you to do this for all packaged foods, not just ready to eat breakfast cereal.

By dry weight, a food guide serving of ready to eat cereal is 30 grams. In household measures, 30 grams of dry cereal will vary depending on the density, or weight, of the cereal. In general, a serving size of cereal is typically 3/4 to one cup. The serving size for denser cereals such as granola and muesli is 1/3 to 1/2 cup. If youre counting calories, manage your portion size by reading the nutrition label and then measuring out the stated serving size.

21-01-2012 10:04 CLICK HERE... quickweightlosstip.org Essential Tips For Quick Weight Loss Most people would agree that being overweight affects more than a person's outward appearance. Those dealing with excess weight may also experience health issues, low-self esteem and even depression. Being overweight also frequently restricts one's ability to perform specific tasks or activities. Those who have decided that the time has come to shed their excess pounds may wish to consider the following tips for quick weight loss: Building Muscle One highly effective way to speed up one's metabolism is to add a weight lifting routine to his or her exercise program. The human metabolism must burn a higher number of calories to maintain a pound of muscle than a pound of fat. For this reason, the more muscle a person builds, the faster his or her metabolism will burn calories. Additionally, weight training also strengthens and improves one's general health. Cutting Calories Wisely Many people are tempted to drastically cut their daily intake of calories. However, this can result in one's metabolism going into what is called starvation mode, which means a considerable slowing of his or her metabolism. It is far better for dieters to change the type of food they eat rather than simply reduce the number of calories they consume. Choosing a low carbohydrate, high protein diet plan is one of the quickest ways to speed weight loss. While all carbohydrates are not bad, foods that contain white sugar and white ...

A Hollywood company's dietary supplements promised herbal solutions to problems of weight loss and male sexual performance.

But the Food and Drug Administration says the supplement SlimXtreme contains a controversial obesity drug no longer sold in the United States because it raises the risk of heart attack and stroke, and ViaXtreme contains the active ingredient of Viagra.

Globe All Wellness LLC, located on Stirling Road in Hollywood, has received a warning letter from the FDA, saying the undeclared presence of these drugs constituted a violation of the law and giving the firm 15 business days to comply or face legal action.

Eran Hamami, the company's president, blamed counterfeit versions of the supplements. He said the company conducted its own laboratory tests of its supplements and did not find these drugs in them. Still, he said, the firm had initiated voluntary recalls of SlimXtreme and ViaXtreme and was cooperating with the FDA.

""We do care about our customers," he said. "Herbal means herbal, and we take that very seriously."

The company's web site markets SlimXtreme as "a proprietary blend of all-natural ingredients designed to lose weight fast and strongly increase your energy" and claimed it "has been proven to be the most efficient and safe weight loss solution on the market."

The site lists ingredients such as bitter orange, konjac root and lotus leaf. And it includes testimonials from satisfied customers such as "Jennifer" from Miami who said, "I just wanted to say thank you for the great product SlimXtreme, which made me lose 22 pounds in just one monthThank you and I will definitely do business with you again."

The FDA letter says laboratory tests found the product contained sibutramine hydrochloride, the active ingredient in an obesity drug that was withdrawn from the U.S. market in 2010.

"Sibutramine may pose serious health risks to consumers, including adverse health consequences such as heart attack, stroke, increased blood pressure, hallucinations, coma, and tachycardia for individuals with existing medical conditions," the letter states.

The web page for ViaXtreme claims it was "prepared exclusively from all-natural herbs and used for centuries to enhance sexual pleasure." Among these ingredients, it says is ginseng, Asiatic dogwood and horny goat weed.

The makers of the QuickTrim weight loss supplements endorsed by reality TV stars the Kardashians are making false, misleading and unsubstantiated claims about their efficacy, according to a class action lawsuit.

The action, filed in New York last Thursday by plaintiffs representing consumers of QuickTrim products in New York, Florida and California, alleges that QuickTrims caffeine pills are mixed with a variety of herbal ingredients that have never been clinically proven as effective treatments for weight loss or appetite suppression.

No competent and reliable scientific evidence

It adds: TheQuickTrim Weight Loss System is marketed by the defendants as a clinically proven formula that will increase metabolism, curb appetite and promote weight loss [But]there is no competent and reliable scientific evidence supporting any of these claims.

Defendants marketing and promotion of QuickTrim includes numerous unsubstantiated, false and misleading claims about the products efficacy and mechanism of action.

Caffeine and weight loss

It also notes that the FDA has determined that there are inadequate data to establish the general recognition of the safety and effectiveness of caffeine as a weight control ingredient.

However, food law experts pointed out to NutraIngredients-USA that this FDA determination was made in relation to 21 C.F.R. 310.545 (which covers active ingredients in OTC drugs not dietary supplements), suggesting that the plaintiffs had misinterpreted regulations pertaining to OTC drugs as applying to dietary supplements.

The defendants are retailers GNC, Walmart, CVS, Amazon.com and Drugstore.com;celebrities Kim Kardashian, Kourtney Kardashian and Khloe Kardashian-Odom; QuickTrim chief executive Christopher Tisi; QuickTrim LLC (which owns the IP rights to the weight loss system) and Windmill Health Products, which distributes the QuickTrim products.

The lawsuit, filed by the law firm of Bursor & Fisher, seeks damages and a jury trial.
