What are the five controversial weight loss supplements promoted by Dr. Oz. How effective are these supplements according to scientific research. What concerns have been raised about Dr. Oz’s endorsement of these products. What did Dr. Oz say in his defense at the Senate hearing.

The “Oz Effect”: How Dr. Oz’s Endorsements Impact Supplement Sales

Dr. Mehmet Oz, host of “The Dr. Oz Show,” has become a influential figure in the world of health and wellness. His endorsements of various supplements and weight loss products have led to a phenomenon known as the “Oz Effect”. When Dr. Oz mentions a product on his show, it often sells out instantly, demonstrating the power of his recommendations.

However, this influence has come under scrutiny, particularly regarding weight loss supplements that Dr. Oz has labeled as “miracle” products. The U.S. Senate Committee on Commerce, Science and Transportation’s Subcommittee on Consumer Protection, Product Safety and Insurance held a hearing to address concerns about these claims.

Green Coffee Bean Extract: The “Magic Weight-Loss Cure”?

One of the most notable supplements promoted by Dr. Oz is green coffee bean extract. He described it as a “magic weight-loss cure for every body type” during a 2012 episode of his show. The main active ingredients in green coffee bean extract are chlorogenic acids.

Dr. Oz defended his endorsement by citing a study that showed weight loss in participants who took the supplement. However, it was noted that this study was funded by the product’s manufacturer, raising questions about potential bias.

Potential Risks of Green Coffee Bean Extract

Recent research has raised concerns about the safety and efficacy of green coffee bean extract. A study published in the Journal of Agricultural and Food Chemistry found that chlorogenic acid:

• Did not prevent weight gain in mice fed a high-fat diet
• Was linked to an unhealthy buildup of fat in the liver

These findings suggest that the supplement may not only be ineffective but potentially harmful.

Raspberry Ketones: “The No. 1 Miracle Fat-Burner”?

Dr. Oz has referred to raspberry ketones as “the No. 1 miracle” fat-burner. This compound, found naturally in raspberries, has been the subject of some scientific research, but its effectiveness for weight loss in humans remains unproven.

What Does the Research Say About Raspberry Ketones?

The current state of research on raspberry ketones can be summarized as follows:

• Some animal studies suggest it might increase certain measures of metabolism
• No reliable scientific evidence supports its effectiveness for weight loss in humans
• No studies have examined its safety and appropriate dosage for human consumption

Given the lack of human studies, the use of raspberry ketones for weight loss remains controversial and potentially risky.

Garcinia Cambogia Extract: Mixed Results and Conflicting Evidence

Garcinia cambogia, a small fruit native to Southeast Asia, was featured on Dr. Oz’s show as one of “The Newest, Fastest Fat Busters”. The extract contains hydroxycitric acid (HCA), which is claimed to aid in weight loss. However, scientific studies have produced mixed results regarding its effectiveness.

Contradictory Findings on Garcinia Cambogia

A notable study published in The Journal of the American Medical Association in 1998 found surprising results:

• Participants who took garcinia cambogia extract as part of their weight-loss diet actually lost less weight than the control group
• The control group took a placebo but still outperformed the supplement group in terms of weight loss

These findings contradict the claims made about garcinia cambogia’s effectiveness for weight loss.

African Mango Diet Pill: Unproven Claims and Lack of Evidence

Irvingia, also known as African mango extract, is another product that Dr. Oz has discussed on his show as a potential weight loss aid. However, scientific evidence supporting its effectiveness is lacking.

What Do the Studies Say About African Mango Extract?

A comprehensive review of studies published in the Journal of Dietary Supplements in 2013 reached the following conclusions:

• The effects of African mango extract on body weight and related outcomes are unproven
• There is insufficient evidence to recommend it as a weight-loss aid
• More robust, independent studies are needed to evaluate its potential benefits and risks

Given these findings, the promotion of African mango extract as a weight loss supplement remains controversial.

Saffron Extract: From Culinary Spice to Contested Supplement

Saffron, an expensive and exotic spice commonly used in Middle Eastern cuisine, has been promoted by Dr. Oz as a “miracle appetite suppressant”. While saffron has a long history of use in traditional medicine and folklore, modern scientific evidence supporting its use for weight loss is limited.

Evaluating the Claims About Saffron Extract

The current state of research on saffron extract for weight loss can be summarized as follows:

• Traditional uses include mood enhancement, but these effects are not well-studied
• No independent studies have found that saffron extract helps people lose weight
• The “miracle appetite suppressant” claim is not supported by scientific evidence

The lack of scientific support for saffron extract as a weight loss aid raises questions about the validity of promoting it as such.

Dr. Oz’s Defense: Motivation vs. Scientific Rigor

During the Senate hearing, Dr. Oz defended his promotion of these supplements, offering insights into his perspective and motivations. His defense centered around several key points:

Dr. Oz’s Rationale for Promoting Supplements

Dr. Oz provided the following explanations for his approach:

• He uses “flowery language” to give his audience hope and motivation to lose weight
• He believes his audience already knows that diet and exercise are essential for weight loss
• He personally believes in the products he promotes, even if they lack strong scientific evidence
• He claims to passionately study these supplements
• He states that he would give his family the same advice he gives his audience

Dr. Oz’s defense highlights the tension between providing motivation and adhering to strict scientific standards in health communication.

The Ethics of Promoting Unproven Supplements

The controversy surrounding Dr. Oz’s promotion of these weight loss supplements raises important ethical questions about the responsibility of public figures in the health and wellness space.

Balancing Hope and Science

Key ethical considerations include:

• The potential harm of promoting products without strong scientific evidence
• The impact of the “Oz Effect” on consumer behavior and spending
• The role of medical professionals in public health communication
• The balance between providing hope and maintaining scientific integrity

These issues highlight the complex relationship between media, science, and public health.

The controversy surrounding Dr. Oz’s promotion of weight loss supplements underscores the importance of critical thinking and scientific literacy in evaluating health claims. While the desire for easy weight loss solutions is understandable, it’s crucial to approach such claims with skepticism and rely on evidence-based methods for achieving and maintaining a healthy weight.

As consumers, it’s essential to consult with healthcare professionals and rely on well-established scientific research when making decisions about supplements and weight loss strategies. The “Oz Effect” serves as a reminder of the powerful influence media figures can have on public health perceptions and behaviors, highlighting the need for responsible communication of health information.

Ultimately, the most reliable approaches to weight management remain a balanced diet, regular physical activity, and lifestyle changes supported by scientific evidence. While supplements may play a role in some individuals’ health regimens, they should not be viewed as miraculous solutions or substitutes for proven health practices.

The ongoing debate surrounding Dr. Oz’s endorsements serves as a valuable opportunity for public education about the importance of scientific evidence in health claims and the need for critical evaluation of weight loss products and strategies. As research in nutrition and weight management continues to evolve, it’s crucial to stay informed and approach health-related claims with a discerning eye, prioritizing well-established scientific findings over sensational promises of “miracle” cures.

Dr. Oz’s ‘Miracle’ Diet Pills: 5 Controversial Supplements

This week, Dr. Mehmet Oz, host of “The Dr. Oz Show,” sat down to explain to senators why he, as a surgeon and popular doctor, promotes what some experts have called unscientific claims about “magical” weight-loss products on his show.

Sen. Claire McCaskill, D-Mo. — chairwoman of the U.S. Senate Committee on Commerce, Science and Transportation’s Subcommittee on Consumer Protection, Product Safety and Insurance — led a panel on Tuesday (June 17) that targeted weight-loss diet products that their manufacturers claim will help consumers burn fat but have little or no reputable scientific data to support such claims.

“I don’t get why you need to say this stuff, because you know it’s not true,” McCaskill told Oz.

On his show, Oz has called some herbal weight-loss products  the “magic weight-loss cure” and “the No. 1 miracle in a bottle.” Once these products are mentioned on the show, they can sell out instantly — a phenomenon known as the “the Oz effect. ”

However, Oz said he uses “flowery language” to give his audience a little nudge of hope and motivation to lose weight, because they already know that adjusting diet and exercising are the things they need to do. [ 10 Fitness Apps: Which Is Best for Your Personality? ]

He added that he personally believes in the products he promotes, even though scientifically, they might not hold up.

“I actually do personally believe in the items I talk about on the show. I passionately study them. I recognize that, oftentimes, they don’t have the scientific muster to present as fact. Nevertheless, I would give my audience the same advice I give my family, and I have given my family these products,” Oz said.

Here is a look at some of the supposedly metabolism-boosting, weight-loss supplements Oz has endorsed, for which there’s scarce scientific data:

Green coffee bean extract: Perhaps the most well-known weight-loss supplement that Oz has popularized is green coffee bean extract, whose major ingredients are chlorogenic acids. “You may think magic is make-believe, but this little bean has scientists saying they’ve found the magic weight-loss cure for every body type. It’s green coffee extract,” Oz said about the supplement during an episode that aired in 2012.

Testifying in front of the panel, Oz defended his endorsement of green coffee beans by citing a study that found people who took the supplements did lose weight. However, that study was funded by the product’s manufacturer, McCaskill noted.

These purported weight-loss supplements could even be harmful, recent research suggests. A study in mice, published last year in the Journal of Agricultural and Food Chemistry, found that chlorogenic acid in green coffee bean extract didn’t help prevent weight gain in mice fed a high-fat diet and was linked to an unhealthy buildup of fat in the liver.

Raspberry ketone: Oz has called raspberry ketones “the No. 1 miracle” fat-burner. This compound found in raspberries has been tested in animals and in cells in the lab, but never for weight loss in humans. Some research in animals has suggested that it might increase some measures of metabolism. Still, there is no reliable scientific proof that it improves weight loss in people, and no study has examined its safety and dosage.

Garcinia cambogia extract: Garcinia cambogia is a small, tasty fruit native to Southeast Asia, and was featured in Oz’s “The Newest, Fastest Fat Busters” episode. The extract contains a compound called hydroxycitric acid (HCA) that is touted for weight loss, but studies have produced mixed results. One study, a randomized controlled trial published in The Journal of the American Medical Association in 1998, even found that people who took the supplement as part of their weight-loss diet lost less weight than the control group who took a placebo.

African mango diet pill: Irvingia, or African mango extract, is another product touted for weight loss that Oz has talked about on his show. In a 2013 review of studies, published in the Journal of Dietary Supplements, the researchers concluded that the effects of this supplement on body weight and related outcomes were unproven, and therefore, they said, the supplement could not be recommended as a weight-loss aid.

Saffron extract: This expensive, exotic spice that is frequently used in Middle Eastern cooking has much folklore describing its ability to lighten up mood, but modern science hasn’t found it is a “miracle appetite suppressant” as Oz has claimed. No independent studies of the supplement have found that it helps people lose weight.

Dr. Oz’s Raspberry Ketones Dismissed by Dietitian as TV Hype

Is Dr. Oz more showman than doctor? His theatrical endorsement of dubious weight loss products points to the former. On his show this week, in a 75-second segment, he introduced a ‘revolutionary metabolism booster that you’ve never heard of’: raspberry ketones. While displaying a generic purple jar of capsules, Dr. Oz said, “I have vetted these; I’ve looked at them carefully; I am absolutely enamored. I know they work.” His segment assistant Lisa Lynn, a supplement-selling personal trainer, was by his side, along with a morbidly obese woman who had “tried everything.” Was Dr. Oz laying it on thick for a questionable product? No, not when you consider Dr. Oz is on TV.

Raspberry ketones are compounds that give red raspberries their aroma. In the US, they are used primarily in the food flavor industry. In Japan, however, raspberry ketone capsules are used as a weight loss supplement. Raspberry ketones are not to be confused with blood ketones produced in diabetes and on very low carbohydrate diets.

The hypothesis is that raspberries ketones affect biological activities that alter lipid metabolism. That fat-blasting claim rests on two small mice studies that show when mice are fed a high-fat diet supplemented with raspberry ketones they gain less body fat than expected. But be clear: raspberry ketones have not been studied in humans and they have not been proven to work. To be fair, Dr. Oz said, “There have not been a lot of human studies, but animal studies are favorable.” Somehow, for me, that got lost in the hype.

To strengthen his points, Dr. Oz asked Lisa if she has “lots of clients who swear by raspberry ketones.” Lisa agreed they “swear by it” and she has seen “firsthand results from these products.” Her word is apparently meant to substitute for randomized controlled research published in peer-reviewed journals. 

Lisa goes on to recommend a dose of ‘100 mg at breakfast and, if that amount isn’t giving you optimal results, take another 200 milligrams at lunch.’ That dose, 100 to 300 mg/day, is the human dose equivalent of what worked in laboratory mice. Unfortunately, that dose costs around $20 to $60 a month, for a still unproven product.

For anyone unwilling to take a supplement, eating raspberries will also work, according to Dr. Oz and Liza. But, while raspberries are good food, that won’t do the fat-busting trick: it takes 90 pounds of raspberries to extract the daily dose of raspberry ketones. Raspberry ketone capsules are actually synthesized in the lab because supply is scarce, demand is growing, and they are expensive.

And so, did Dr. Oz lead us astray on the raspberry ketone claim? He did if you believe he has a medical obligation to the viewer. Call me jaded, but I believe Dr. Oz’s only obligation is to his network. I don’t say I agree with it, but it is what it is, at least for today. We, the viewers, are obligated to watch out for ourselves and our families. We are obligated to distinguish between legitimate medical fact and TV hype. It makes sense to be wary of products that promise a quick fix and dramatic results, regardless of the credentials of the person who said it. Never give credit to recommendations based on small animal studies, and realize that supplement makers depend on gullible TV viewers to buy useless products. Dr. Oz may think his endorsement jives with the Hippocratic Oath to “first, do no harm,” and he’s right. Raspberry ketones have not been shown to be harmful to humans, yet.

What are Raspberry Ketones? How It Works For Weight Loss

April 20
2019

How to lose weight? What can I do to stop eating so much? How about without chemicals? And without sports?
Without sports, no, but naturally and without chemistry, yes!

First of all, let’s not forget about vitamins and minerals, which directly or indirectly affect the state of not only our health, but also our body.

And we also take natural plant substances to help. Today I will tell you about one of them.

RASPBERRY KETONE

Raspberry Ketone is a supplement that helps increase your chances of getting a slim and beautiful figure. Works similarly to thermogenic fat burners, but without the side effects.

Raspberry ketone – what is it?

Raspberries contain about 200 molecules that are responsible for their taste. One of these is raspberry ketones, which have long been isolated and valued by food manufacturers for their strong odor. Raspberry ketones are used to make candy, soaps and candles, and other food and care products. Recently, scientists have turned to raspberry ketones again, this time, however, for their ability to lose weight.

Puritan’s Pride Raspberry Ketones

Around 2010, scientists noticed that raspberry ketones had a similar molecular structure to capsaicin, which is the substance responsible for the spice in chili peppers. Initial research also showed that capsaicin prevented weight gain. In light of these findings, the researchers conducted studies in mice and human tissue to see if raspberry ketones affect weight loss.

How it works for weight loss

It works as a thermogenic fat burner to increase body temperature. It burns fat in a similar way to l-carnitine, caffeine, and numerous thermogenic supplements in sports nutrition stores. Causes the release of norepinephrine, which warms the body and increases lipolysis. Safe and effective fat burner

• Increased levels of adiponectin (hormone that is involved in the regulation of glucose levels and the breakdown of fatty acids
• Strong thermogenic properties
• Metabolism optimization, lipolysis stimulation
• Appetite control Effective in the fight against obesity and diabetes
• Recommended during diet
• Increases insulin sensitivity

Raspberry Ketone Side Effects

The advantage of pure raspberry ketones over other thermogenics is that they are safe to use.
