This randomized, double-blind study evaluated the efficacy of a homeopathic treatment in preventing excessive weight gain during pregnancy in overweight or obese women who were suspected of having a common mental disorder. For the homeopathic group (n=62), 9 homeopathic remedies were pre-selected: (1) Pulsatilla nigricans, (2) Sepia succus, (3) Lycopodium clavatum, (4) sulphur, (5) Lachesis trigonocephalus, (6) Nux vomica, (7) Calcarea carbonica, (8) phosphorus; and (9) Conium maculatum. From those 9 drugs, one was prioritized for administration for each participant. After the first appointment, a re-selection or selection of a new, more appropriate drug occurred, using the list of preselected drugs. The dosage was 6 drops orally 2 ×/day, in the morning and at night, on 4 consecutive days each week, with an interval of 3 d between doses, up until the next appointment medical appointment. The control group (n=72) took placebos. Both groups also received a diet orientation.
Weight change during pregnancy was defined as the difference between the body mass index (BMI) at the initial evaluation and that recorded at the final evaluation, adjusted for 40 weeks of gestation. In addition, the APGAR index in the newborn (a measure of the health of the baby) was evaluated. The mean variation between baseline BMI and BMI at week 40 of gestation was +4.95 kg/m2 in the control group and +5.05 kg/m2 in the homeopathy group. The difference between the two groups was not significant. APGAR 10 at 5 min (59.6% in the homeopathy group and 36.4% in the control group) was statistically significant (P = .016).
The authors concluded that homeopathy does not appear to prevent excessive body mass gain in pregnant women who are overweight or obese and suspected of having a common mental disorder. Homeopathy did not change the APGAR score to modified clinical attention at delivery room. However, the evidence observed at APGAR 10 at minute 5 suggests that homeopathy had a modulating effect on the vitality of newborns, warranting further studies designed to investigate it.
I have seen many odd studies in my time, but this must be one of the oddest?
- What is the rationale for assuming that homeopathy might affect body weight?
- Why take pregnant women with a weight problem who were suspected of having a common mental disorder?
- Why try to turn a clearly negative result into a finding that is (at least partly) positive?
The last point seems the most important one to me. The primary outcome measure of this study (weight gain) was clearly defined and was not affected by the therapy. Yet the authors feel it justified to add to their conclusions that homeopathy had a modulating effect on the vitality of newborns (almost certainly nothing but a chance finding).
Are they for real?
I suppose they are: they are real pseudo-scientific promoters of quackery!
It has been reported that ‘Boots the Chemist’ have filed several legal complaints against The Guardian in relation to articles published by the paper in relation to its April 2016 investigation. The Guardian articles in question alleged that Boots, the UK’s largest pharmacy chain, had placed undue pressure on its pharmacists to perform medicines use reviews so that it could claim the maximum payments possible from the NHS. In other words, The Guardian implied that Boots was trying to get more money from our NHS than might have been due.
Personally, I am always uneasy when I hear that someone takes legal action on such matters. I think that legal complaints of such a nature can turn out to be counter-productive, both in general and in this particular instance.
There could be several reasons. For instance, such actions might give someone the idea of filing complaints against Boots. I am sure it is not difficult to find reasons for that.
In the realm of alternative medicine, for example, someone might question whether selling homeopathic remedies in Boot’s section ‘pharmacy and health’ is not misleading. These remedies might be seen by a naïve customer as masquerading as medicines. As readers of this blog know all too well, they do not, in fact, contain anything (other than lactose) that has any pharmacological activity. Therefore Boots should best market them in the category of ‘confectionary’.
One might even suspect that Boots are fully aware of all this. After all, a spokesperson for the company stated years ago during a parliamentary inquiry: “I have no evidence to suggest that they [homeopathic remedies sold by Boots] are efficacious …”
And it is also not the first time that Boots have been challenged for selling products they know to be placebos. This is what The Guardian reported in 2008 about the issue: “Ernst accuses the company [Boots] of breaching ethical guidelines drawn up by the Royal Pharmaceutical Society of Great Britain, by failing to tell customers that its homeopathic medicines contain no active ingredients and are ineffective in clinical trials.”
A similar void of evidence also applies to Boot’s wide range of Bach Flower Remedies and aromatherapy oils.
Or am I wrong?
Perhaps Boots want to post links to the evidence in the comment section below?
I am always keen to learn and only too happy to change my mind in view of new, compelling evidence!
Boots also sell a very wide range of herbal medicines, and here the situation is quite different: herbal medicines actually contain molecules that might have pharmacological effects, i. e. they might heal or might harm you. And many of these products imply indications for which they should be taken. I will pick just one example to explain: HERBAL SLIM AID.
Yes, you are absolutely correct – this product is (according to its name) not for gaining weight, it’s for reducing it. Each coated tablet contains 45 mg of extract (as dry extract) from Bladderwrack thallus (Fucus vesiculosus L.) (5:1) (equivalent to 225 mg of Fucus) Extraction solvent: water, ,30 mg Dandelion Root (Taraxacum officinale Weber ex Wigg), 27 mg of extract (as dry extract) from Boldo leaf (Peumus boldus Molina) (4-6:1) (equivalent to 108-162 mg of Boldo leaf) Extraction solvent: Methanol 70% v/v, 10 mg Butternut Bark (Juglans cinerea L.).
Now, I thought I know quite a bit about herbal slimming aids, after all, we had a research focus on this topic for several years and have published about a dozen papers on the subject. But oddly, I cannot remember that this mixture of herbs has been shown to reduce body weight.
Perhaps Boots want to post evidence for the efficacy and safety of this product as well?
I certainly hope so, and I would instantly withdraw any hint of a suspicion that Boots are selling unproven or disproven medicines.
Where is all this going?
I have to admit that am not entirely sure myself.
I suppose all I wanted to express was that it might be unwise to throw stones when one is sitting in a glass-house – a cliché, I know, but it’s true nevertheless.
CONFLICTS OF INTEREST:
None [except I don’t like those who easily take legal action against others]
John Garrow died yesterday at home.
John had suffered a stroke about 6 weeks ago but had previously been in good health.
His professional achievements were too many to list here in full. He had been Professor of Human Nutrition, University of London, Honorary consultant physician St Bartholomew’s Hospital, St Mark’s Hospital, Royal London Hospital and Northwick Park Hospital. He also was head of Nutrition Research Unit at the MRC Clinical Research Centre, Harrow, and member of Department of Health Committee on Medical Aspects of Food Policy; Chair of the Joint Advisory Committee on Nutrition Education and the Chair of Association for the Study of Obesity. For many years, he also acted as editor in chief of the European Journal of Clinical Nutrition, and as the chairman of HealthWatch.
John was a clinician and an active researcher with a focus on nutrition and, occasionally, alternative medicine. He has published many ground-breaking articles on these and other subjects. I had the pleasure to plan, conduct and publish a study with John; it was an investigation into an area which, at the time, was entirely novel. I think it might have been the first RCT into the peer-review system ever conceived. Here is the full abstract:
A study was designed to test the hypothesis that experts who review papers for publication are prejudiced against an unconventional form of therapy. Two versions were produced (A and B) of a ‘short report’ that related to treatments of obesity, identical except for the nature of the intervention. Version A related to an orthodox treatment, version B to an unconventional treatment. 398 reviewers were randomized to receive one or the other version for peer review. The primary outcomes were the reviewers’ rating of ‘importance’ on a scale of 1-5 and their verdict regarding rejection or acceptance of the paper. Reviewers were unaware that they were taking part in a study. The overall response rate was 41.7%, and 141 assessment forms were suitable for statistical evaluation. After dichotomization of the rating scale, a significant difference in favour of the orthodox version with an odds ratio of 3.01 (95% confidence interval, 1.03 to 8.25), was found. This observation mirrored that of the visual analogue scale for which the respective medians and interquartile ranges were 67% (51% to 78.5%) for version A and 57% (29.7% to 72.6%) for version B. Reviewers showed a wide range of responses to both versions of the paper, with a significant bias in favour of the orthodox version. Authors of technically good unconventional papers may therefore be at a disadvantage in the peer review process. Yet the effect is probably too small to preclude publication of their work in peer-reviewed orthodox journals.
Years later, John also contributed a chapter entitled ‘CAM IN COURT’ to a book that I had edited. I remember very well what a pleasure it was to co-operate with John. He was quick to conceive new ideas and had an intellectual rigor and honesty that I have not often encountered elsewhere.
But it is not his professional achievements which impressed me most about John. What I found even more remarkable was his ability to understand, his kindness and warmth. He had the gift not just to grasp the issues but also to empathize with the people behind them. I am proud to have known John, worked with him, and been inspired by him.
I will sorely miss my friend.
The search for an effective treatment of obesity is understandably intense. Many scientists are looking in the plant kingdom for a solution, but so far none has been forthcoming – as we have already discussed on this blog before (e. g. here, and here). One herbal slimming aid is currently becoming popular: Yerba Mate also called Ilex paraguariensis, a plant many of us know from teas and other beverages. Our review concluded that the evidence for it was unconvincing but that it merited further study. This was 10 years ago, and meanwhile the evidence has moved on.
The aim of a recent study was to investigate the efficacy of Yerba Mate supplementation in subjects with obesity. For this purpose, a randomized, double-blind, placebo-controlled trial was conducted. Korean subjects with obesity (body mass index (BMI) ≥ 25 but < 35 kg/m(2) and waist-hip ratio (WHR) ≥ 0.90 for men and ≥ 0.85 for women) were given oral supplements of Yerba Mate capsules (n = 15) or placebos (n = 15) for 12 weeks. They took three capsules per each meal, total three times in a day (3 g/day). Outcome measures were efficacy (abdominal fat distribution, anthropometric parameters and blood lipid profiles) and safety (adverse events, laboratory test results and vital signs).
During 12 weeks of Yerba Mate supplementation, statistically significant decreases in body fat mass and percent body fat compared to the placebo group were noted significant. The WHR was significantly also decreased in the Yerba Mate group compared to the placebo group. No clinically significant changes in any safety parameters were observed.
The authors concluded that Yerba Mate supplementation decreased body fat mass, percent body fat and WHR. Yerba Mate was a potent anti-obesity reagent that did not produce significant adverse effects. These results suggested that Yerba Mate supplementation may be effective for treating obese individuals.
These are encouraging results, but the conclusions go way too far, for my taste. The study was tiny and does therefore not lend itself to far-reaching generalisations. What would be helpful, is a review of other evidence. As it happens, such a paper has just become available. Its authors evaluated the impact of yerba maté on obesity and obesity-related inflammation and demonstrate that yerba maté suppresses adipocyte differentiation as well as triglyceride accumulation and reduces inflammation. Animal studies show that yerba maté modulates signaling pathways that regulate adipogenesis, antioxidant, anti-inflammatory and insulin signaling responses.
The review authors concluded that the use of yerba maté might be useful against obesity, improving the lipid parameters in humans and animal models. In addition, yerba maté modulates the expression of genes that are changed in the obese state and restores them to more normal levels of expression. In doing so, it addresses several of the abnormal and disease-causing factors associated with obesity. Protective and ameliorative effects on insulin resistance were also observed… it seems that yerba maté beverages and supplements might be helpful in the battle against obesity.
I am still not fully convinced that this dietary supplement is the solution to the current obesity epidemic. But the evidence is encouraging – more so than for most of the many other ‘natural’ slimming aids that are presently being promoted for this condition by gurus like Dr Oz.
What we needed now is not the ill-informed, self-interested voice of charlatans; what we need is well-designed research to define efficacy, effect size and risks.
Times are hard, also in the strange world of chiropractic, I guess. What is therefore more understandable than the attempt of chiropractors to earn a bit of money from people who want to lose weight? If just some of the millions of obese individuals could be fooled into believing that chiropractic is the solution for their problem, chiropractors across the world could be laughing all the way to the bank.
But how does one get to this point? Easy: one only needs to produce some evidence suggesting that chiropractic care is effective in reducing body weight. An extreme option is the advice by one chiropractor to take 10 drops of a homeopathic human chorionic gonadotropin product under the tongue 5 times daily. But, for many chiropractors, this might be one step too far. It would be preferable to show that their hallmark therapy, spinal adjustment, leads to weight loss.
With this in mind, a team of chiropractors performed a retrospective file analysis of patient files attending their 13-week weight loss program. The program consisted of “chiropractic adjustments/spinal manipulative therapy augmented with diet/nutritional intervention, exercise and one-on-one counselling.”
Sixteen of 30 people enrolled completed the program. At its conclusion, statistically and clinically significant changes were noted in weight and BMI measures based on pre-treatment (average weight = 190.46 lbs. and BMI = 30.94 kg/m(2)) and comparative measurements (average weight = 174.94 lbs. and BMI = 28.50 kg/m(2)).
According to the authors of this paper, “this provides supporting evidence on the effectiveness of a multi-modal approach to weight loss implemented in a chiropractic clinic.”
They do not say so, but we all know it, of course: one could just as well combine knitting or crossword puzzles with diet/nutritional intervention, exercise and one-on-one counselling to create a multi-modal program for weight loss showing that knitting or crossword puzzles are effective.
With this paper, chiropractors are not far from their aim of being able to mislead the public by claiming that CHIROPRACTIC CARE IS A NATURAL, SAFE, DRUG-FREE AND EFFECTIVE OPTION IN THE MANAGEMENT OF OBESITY.
Am I exaggerating? No, of course not. There must be thousands of chiropractors who have already jumped on the ‘weight loss band-waggon’. If you don’t believe me, go on the Internet and have a look for yourself. One of the worst sites I have seen might be ‘DOCTORS GOLDMINE’ (yes, most chiropractors call themselves ‘doctor these days!) where a chiropractor promises his colleagues up to $100 000 per month extra income, if they subscribe to his wonderful weight-loss scheme.
It would be nice to be able to believe those who insist that these money-grabbing chiropractors are but a few rotten apples in a vast basket of honest practitioners. But I have problems with this argument – there seem to be far too many rotten apples and virtually no activity or even ambition to get rid of them.
Dr. Oz, famous through his TV show promoting all types of quackery, recently testified before a US Senate subcommittee hearing on protecting consumers from false and deceptive advertising of weight loss products. This event turned out to be less than flattering for Dr Oz. One journalist commented that he “might as well be a cowardly lion — sent home with his tail between his legs after being accused at a congressional hearing of lying on his show about weight-loss claims.”
“I don’t get why you need to say this stuff, because you know it’s not true,” said Senator Claire McCaskill, who led the commerce subcommittee hearing. “The scientific community is almost monolithically against you in terms of the efficacy of the products you called ‘miracles,’ ” the Democratic senator from Missouri told Oz. “It’s a major problem when people are spending more and more money and they’re gaining more and more weight,” said Senator Amy Klobuchar.“Either you don’t talk about these things at all, or you’re going to have to be more specific because right now . . . this is not working.”
A source close to Dr Oz said he was perplexed: “We were invited down to Washington to testify at a hearing about scams and instead it became all about how much we hate your show.” Oz himself testified that he “heard the message…I do personally believe in the items that I talk about.”
“I intensively study them. I have given my family these products. . . . If you can lose a pound a week more than you would have lost by using them, it jump-starts you and gets you going. I think it makes sense.” “I’m surprised you’re defending this,” McCaskill replied. “It’s something that gives people false hope. I don’t see why you need to go there.”
Another journalist commented that the Senators repeatedly placed him on the defense over his weight loss products: “I know you know how much power you have. I know you know that. You are very powerful and [with] power comes a great deal of responsibility,” Senator Claire McCaskill , who led the Senate’s consumer protection hearing titled “Protecting Consumers from False and Deceptive Advertising of Weight-Loss Products…You are being made an example of today because of the power you have in this space…We didn’t call this hearing to beat up on you but we did call this hearing to talk about a real crisis in consumer protection. You can either be part of the police here or you can be part of the problem.”
Oz insisted he was no huckster but admitted the products promoted on his show don’t always have “the scientific muster” to present their benefits as “fact…I actually do personally believe in the items that I talk about in the show. I passionately studied them. I recognize that oftentimes they don’t have the scientific muster to present as fact but nevertheless I would give my audience the advice I give my family all the time. And I have given my family these products,” he said.
Dr Oz also said that some alternative treatments, such as prayer, cannot be tested scientifically. “I don’t think this ought to be a referendum on the use of alternative medical therapies. Because if that’s the case, listen, I’ve been criticized for having folks coming on my show talking about the power of prayer,” he said. “I can’t prove that prayer helps people survive an illness.”
No, Dr Oz! I know you are mistaken! I have done the research – both on alternative slimming aids and on spiritual healing. The results quite clearly show that these methods are not more effective than a placebo.
Pyruvate, a ketone and an alpha-keto acid, occurs naturally in the body when glucose is converted into energy. It is part of the Krebs cycle, the complex chain of reactions in which nutrients are metabolised to provide energy. High doses of pyruvate seem to stimulate the breakdown of fat in the body. It is therefore not surprising that pyruvate is used in all sorts of slimming aids; and if the advertising for ‘fat burners’ is to be believed, pyruvate is just the ticket for the desperate slimmer.
One such product advertisement, for instance, claims that sodium pyruvate and potassium pyruvate, which can act as a stimulant for the metabolism, adding to the thermogenesis process. Pyruvates have been found in studies to reduced the storage of fat in the body and convert the food source into calories which are then burned off in the production of heat. In one study, rats were injected with three fat burners, including pyruvates, and the rats given the pyruvates burned the greatest amount of fat by increasing the rat’s resting metabolic rate. With the elevated resting metabolic rate, the body burned more fat in individuals, which makes pyruvate an excellent source for weight maintenance.
So, maybe pyruvate works for rats – but does it really help those of us who would like to lose a few kilos? Some studies seem to say so, but others don’t. What do we conclude? There can only be one solution: we need a systematic review of the totality of the available trial evidence – and you probably guessed it: we have just published such an article.
The objective of our systematic review was to examine the efficacy of pyruvate in reducing body weight. Extensive literature searches identifies 9 RCTs of which 6 were met our inclusion criteria. All had methodological weaknesses. The meta-analysis revealed a statistically significant difference of 0.72 kg in body weight with pyruvate compared to placebo. The magnitude of the effect is small, and its clinical relevance is therefore uncertain. Adverse events included gas, bloating, diarrhoea, and increase in low-density lipoprotein cholesterol.
Our conclusion: The evidence from randomized clinical trials does not convincingly show that pyruvate is efficacious in reducing body weight. Limited evidence exists about the safety of pyruvate. Future trials involving the use of this supplement should be more rigorous and better reported.
Pyruvate supplements are popular; people who want to lose weight are misled into believing that they are effective. Bodybuilders as well as other athletes tend to take them because pyruvate is claimed to reduce body fat and enhance the ability to use energy more efficiently. None of these assumptions is based on sound evidence. Regardless of the evidence, a whole industry is exploiting the gullible and doing very well on it.
As these ‘fat burners’ are by no means cheap, I recommend a more efficient and more economical method for normalising body weight: eat a little less and move a bit more – I know it’s naff, but it works!
It hardly is a secret: we have a growing problem with obesity. Worldwide it is predicted to cause millions of premature deaths – unless, of course, we come up with a safe and effective treatment that patients find acceptable.
Many herbal remedies are being promoted as the solution to this serious problem. My team looked at the evidence for such treatments in much detail. Sadly the results were less than impressive.
But now, there seems to be new hope! Two recent studies of a specific herbal mixture report amazingly good results – or are they perhaps too good to be true?
Stern JS, Peerson J, Mishra AT, Sadasiva Rao MV and Rajeswari KP from the Department of Nutrition and the Department of Internal Medicine, University of California Davis, have just published an RCT in 60 subjects with body mass index (BMI) between 30 and 40 kg/square meter. Participants received either 400 mg herbal capsules with extracts from Sphaeranthus indicus and Garcinia mangostana or 400 mg placebo capsules twice daily. During the study period, participants consumed a standard diet (2,000 kcal per day) and walked 30 min 5 days per week.
After 8 weeks of this treatment, significant reductions in body weight (3.7 kg), BMI (1.6 kg/m2), and waist circumference (5.4 cm) were observed in the herbal group compared with placebo. Additionally, a significant increase in serum adiponectin concentration was found in the herbal group versus placebo. Adverse events were mild and were equally distributed between the two groups.
The authors’ conclusion leave no doubt: Supplementation with the herbal blend resulted in a greater degree of weight loss than placebo over 8 weeks.
As our own review had suggested that extracts of Garcinia cause small short-term weight reductions, the results did not come as a complete surprise to me. What did strike me as odd, however, was the fact that almost simultaneously another article was published. It was authored by Stern JS, Peerson J, Mishra AT, Mathukumalli VS and Konda PR from the Department of Nutrition, University of California-Davis, and it reported the pooled data from the above plus another, similarly designed trial.
The two studies together enrolled 100 patients who were treated either with the same herbal formula or with placebo. All subjects received 2000 kcal/day throughout the study and walked 5 days a week for 30 min. The primary outcome was the reduction in body weight. Secondary outcomes were reductions in BMI and in waist and hip circumference. Serum glycaemic, lipid, and adiponectin levels were also measured. Ninety-five subjects completed the trials, and the data from these two studies were pooled and analysed.
At study conclusion (8 weeks), statistically significant reductions in body weight (5.2 kg), BMI (2.2 kg/m2), as well as waist (11.9 cm) and hip circumferences (6.3 cm) were observed in the pooled herbal groups compared with placebo. A significant increase in serum adiponectin concentration was also found in the herbal groups versus placebo at study conclusion along with reductions in fasting blood glucose (12.2%), cholesterol (13.8%), and triglyceride (41.6%) concentrations. No changes were seen across organ function panels, multiple vital signs, and no major adverse events were reported. The minor adverse events were equally distributed between the two groups.
And what should be odd about that? Authors are entitled to pool the data of two of their own trials! Yes, of course, but what confuses me is the fact that the data from the second study of 40 patients cannot be found anywhere. I would have liked to see how it is possible that the results from just 40 more patients (actually just 35 seemed to have been included in the analysis) raise the average weight loss from 3.7 kg in the first RCT to a remarkable 5.2 kg in the two RCTs together. As a rough estimate, this means that, in the second trial, patients who took the herbal mixture must have lost about one kilo per week more than those who were on placebo. If true, this outcome is pretty sensational! It could signal the end of the obesity epidemic. It would also mean that the manufacturer of this herbal wonder mixture stands to earn billions.
Considering the potential importance of these findings, I would also like to know what precisely the Californian researchers’ involvement has been in these two studies. In the second article they state that: The two clinical trials were performed at Alluri Sitarama Raju Academy of Medical Sciences (ASRAM), Eluru, Andhra Pradesh, India from November 2009 to April 2010 (clinical trial registration number: ISRCTN45078827) and from March 2010 to July 2010 (clinical trial registration number: ISRCTN52261953). I find this puzzling.
Moreover, it would be interesting to learn what happened to the following co-authors of the first study: Sadasiva, Rao MV and Rajeswari KP. As authors of the largest of the two trials, I would have thought their names would have to be included in the article reporting the pooled data of the two studies.
Call me sceptical, perhaps even cynical, but I do wonder about trials which seem to beg so many intriguing questions. In case you want to know who funded these studies and who thus stands to make the above-named billions, the answer is provided in the second paper: This work was supported by an unrestricted grant from InterHealth Nutraceuticals Inc., Benicia, CA, to J.S.S.
So, do I think that we have finally identified a safe and effective treatment to combat the worldwide epidemic of obesity? Well….
The developed world is in the middle of a major obesity epidemic. It is predicted to cause millions of premature deaths and billions of dollars, money that would be badly needed elsewhere. The well-known method of eating less and moving more is most efficacious but sadly not very effective, that is to say people do not easily adopt and adhere to it. This is why many experts are searching for a treatment that works and is acceptable to all or at least most patients.
Entrepreneurs of alternative medicine have long jumped on this band waggon. They have learnt that the regulations are lax or non-existent, that consumers are keen to believe anything they tell them and that the opportunities to make a fast buck are thus enormous. Today, they are offering an endless array of treatments which are cleverly marketed, for instance via the Internet.
Since many years, my research team are involved in a programme of assessing the alternative slimming aids mostly through systematic reviews and occasionally also through conducting our own clinical trials. Our published analyses include the following treatments:
Supplements containing conjugated linoleic acid
There are, of course, many more but, for most, no evidence exist at all. The treatments listed above have all been submitted to clinical trials. The results show invariably that the outcomes were not convincingly positive: either there were too few data, or there were too many flaws in the studies, or the weight reduction achieved was too small to be clinically relevant.
Our latest systematic review is a good example; its aim was to evaluate the evidence from randomized controlled trials (RCTs) involving the use of the African Bush Mango, Irvingia gabonensis, for body weight reduction in obese and overweight individuals. Three RCTs were identified, and all had major methodological flaws. All RCTs reported statistically significant reductions in body weight and waist circumference favoring I. gabonensis over placebo. They also suggested positive effects of I. gabonensis on blood lipids. Adverse events included headache and insomnia. Despite these apparently positive findings, our conclusions had to be cautious: “Due to the paucity and poor reporting quality of the RCTs, the effect of I. gabonensis on body weight and related parameters are unproven. Therefore, I. gabonensis cannot be recommended as a weight loss aid. Future research in this area should be more rigorous and better reported.”
People who want to loose weight are often extremely desperate and ready to try anything. They are thus easy victims of the irresponsible promises that are being made on the Internet and elsewhere. Despite the overwhelmingly evidence to the contrary, consumers are led to believe that alternative slimming aids are effective. What is more, they are also misled to assume they are risks-free. This latter assumption is false too: apart from the harm done to the patient’s bank account, many alternative slimming aids are associated with side-effects which, in some cases, are serious and can even include death.
The conclusion from all this is short and simple: alternative slimming aids are bogus.
