bogus claims

1 2 3 21

In my last post, I made a fairly bold statement without any evidence to support it: “[this] demonstrates once again that, in the realm of alternative medicine, organisations and individuals make statements that sound fine and are politically correct, while at the same time disregarding these pompous aims/visions/objectives by promoting outright quackery. This sort of thing is so wide-spread that most of us just take it for granted and very few have the nerve to object. The result of this collective behaviour is obvious: on the one hand, charlatans can claim to be entirely in line with public health, EBM etc.; on the other hand, they are free to exploit the public with their bogus treatments.”

I felt that my statement was supported by so many websites that it was almost self-evident. But, as it happens, I was alerted today to another website that provides impressive first had evidence of what I meant:

“The purpose of this site is to provide the public with information about Craniosacral Therapy

Craniosacral therapists recognise health as an active principle. This health is the expression of life – an inherent ordering force, a natural internal intelligence. Craniosacral Therapy is a subtle and profound healing form which assists this natural bodily intelligence.

It is clear that a living human organism is immensely complex and requires an enormous amount of internal organisation. Craniosacral Therapy helps nurture these internal ordering principles. It helps increase physical vitality and well-being, not only effecting structural change, but also having much wider implications e.g. improving interpersonal relationships, managing life more appropriately etc…

The work can address issues in whatever way the client wishes; physical aches and pains, acute and chronic disease, emotional or psychological disturbances, or simply developing well-being, health and vitality.

Craniosacral Therapy is so gentle that it is suitable for babies, children, and the elderly, as well as adults; and also in fragile or acutely painful conditions. As a whole-body therapy, treatment may aid almost every condition, raising the vitality and enabling the body’s own self-healing process to be utilised.”

I find this text rather typical and very revealing: the authors first make several bland statements which are little more that politically correct platitudes. Eventually, they try to tell us what their therapy is good for: it is suitable for babies adults and the elderly. In other words, it is for everyone!

And what is so truly brilliant, it can be used to treat acute and chronic conditions. In other words, it is effective for every disease afflicting mankind!

Once you have realised it, the strategy of such ‘position statements’ (or whatever they might call it) is all too obvious: behind a smokescreen of empty platitudes, quackery is being promoted for profit. The phraseology used is such that there can be little concrete objections in legal or regulatory terms. All the therapeutic claims are general, cleverly hidden and operate merely by implication.

Quackery? Yes, absolutely!

Craniosacral therapy has not been proven to be effective for anything and, as a therapy, it is therefore not ‘suitable’ for anyone. To me, this is almost the definition of quackery.

A recent post of mine prompted this categorical statement by one of the leading alt med researchers in Germany: naturopathy does not include homeopathy.” This caused several counter-comments claiming that homeopathy is an established part of naturopathy. Now a regular reader has alerted me to the current position paper on homeopathy by the ‘AMERICAN ASSOCIATION OF NATUROPATHIC PHYSICIANS’ (AANP). It clarifies the issue fairly well, and I therefore take the liberty of citing it here in full:

“Overview of Naturopathic Medicine and Homeopathy

Homeopathy has been an integral part of naturopathic medicine since its inception and is a recognized specialty for which the naturopathic profession has created a distinct specialty organization, the Homeopathic Academy of Naturopathic Physicians. Homeopathy has been recognized, through rigorous testing and experimentation, as having significant scientific evidence supporting its efficacy and safety. Single medicines are given on the basis of an individual’s manifestation of a disease state in comparison to combination remedies which are given on the basis of a particular diagnostic category.

Homeopathic products are being subjected to intensified federal regulations and restrictions. Products are being promoted and marketed as “homeopathic” for a variety of uses ranging from weight-loss aids to immunizations. Many of these preparations are not homeopathic and many have not been satisfactorily proven to be efficacious. Homeopathy is practiced in a variety of traditional and non-traditional forms.

Position of the American Association of Naturopathic Physicians:

  • Homeopathy is taught in the naturopathic colleges and its practice should be included in the naturopathic licensing laws. Naturopathic physicians recognize other licensed practitioners of the healing arts who are properly trained in homeopathy.
  • The naturopathic profession initiates more clinical trials and provings to further evaluate the effectiveness of homeopathy.
  • Naturopathic physicians shall be authorized to prescribe and dispense all products included in the Homeopathic Pharmacopoeia of the United States (HPUS).
  • Homeopathic products shall be subject to strict labeling requirements. Preparations which are not prepared in accord with the manufacturing principles in the HPUS should not use the term “homeopathic.” If parents choose homeopathic preparations for their children or their wards for the prophylaxis of infectious disease as an alternative to conventional immunizations, the physician should clearly state that they are unproven and that they are not legal substitutes for the state-mandated requirements.
  • Homeopathic prescriptions should be made with careful evaluation of their effect on the entire organism.
  • Electro-diagnostic testing is an investigational tool. Electro-diagnostic testing should be used according to accepted protocol and it is recommended that it not be relied on as the sole determinant in homeopathic prescribing.”

So, was Prof Michalsen wrong when he stated that “naturopathy does not include homeopathy. It is established in Germany as the application of nutritional therapy, exercise, herbal medicine, balneotherapy and stress reduction, defined by the German Board of Physicians. In conclusion, my general and last suggestion to these kinds of comments and blogs: Please first learn the facts and then comment.”? Not wrong, perhaps – but just a little Teutonic and provincial? The Germans like their own definitions which do not apply to the rest of the world. Nothing wrong with that, I think. But, in this case, they should make it clear that they are talking about something else than the international standard, and perhaps they should also publish their national drivel in their provincial journals in German language. This would avoid all sorts of misunderstandings, I am sure.

But this may just be a trivial aside. The more interesting issue here is the above AANP-statement itself. The AANP has the following vision: “Naturopathic physicians will guide and empower people to discover and experience improved health, optimal wellness, and effective management of disease through the principles and practices of naturopathic medicine.”

These are very nice words; but they are just that: WORDS. The AANP clearly does not believe in their own vision. If they did, they could never speak of ‘EFFECTIVE MANAGEMENT OF DISEASE’ while condoning the use of therapies that have been shown to be ineffective.

And this is where, in my view, the importance of their ‘position paper’ really lies: it demonstrates once again that, in the realm of alternative medicine, organisations and individuals make statements that sound fine and are politically correct, while at the same time disregarding these pompous aims/visions/objectives by promoting outright quackery. This sort of thing is so wide-spread that most of us just take it for granted and very few have the nerve to object. The result of this collective behaviour is obvious: on the one hand, charlatans can claim to be entirely in line with public health, EBM etc.; on the other hand, they are free to exploit the public with their bogus treatments.

Could this be the true common denominator of naturopathy in Germany and the rest of the world?

These days, I spend much of my time in France (my wife is French), and one striking thing about this country is the popularity of homeopathy. For instance, it is hard to find a pharmacy where the pharmacist does not approach you trying to sell you a homeopathic remedy for your health problem. But, of course, this is all far too anecdotal. The question therefore is, are there any reliable data on France’s usage of homeopathy?

The answer is YES: the aim of this new paper was to analyse data on medicines, prescribers and patients for homeopathic prescriptions that are reimbursed by French national health insurance.

The French national health insurance databases were used to analyse prescriptions of reimbursed homeopathic drugs or preparations in the overall French population, during the period July 2011-June 2012.

The results show that a total of 6,705,420 patients received at least one reimbursement for a homeopathic preparation during the 12-month period. This number equates to 10.2% of the French population, with a predominance in females (68%) and a peak frequency observed in children aged 0-4 years (18%). About one third of patients had only one reimbursement, and one half of patients had three or more reimbursements.

The cost of all homeopathic treatments prescribed during the 12-month period was approximately €279 million (based on the retail price). The observed mean reimbursement rate was 34%. This cost corresponded to nearly €98 million for the French national health insurance and amounted to 0.3% of France’s total drug bill. The most commonly prescribed stock was ‘Arnica montana’, followed by ‘Influenzinum’, Ignatia amara’ and ‘Gelsemium sempervirens’.

A total of 120,110 healthcare professionals (HCPs) prescribed at least one homeopathic drug or preparation. They represented 43.5% of the overall population of HCPs, nearly 95% of general practitioners, dermatologists and pediatricians, and 75% of midwives. Homeopathy accounted for 5% of the total number of drug units prescribed by HCPs. Conventional medicines were co-prescribed with 55% of homeopathic prescriptions.

From these data, the authors concluded that many HCPs occasionally prescribe reimbursed homeopathic preparations, representing however a small percentage of reimbursements compared to allopathic medicines. About 10% of the French population, particularly young children and women, received at least one homeopathic preparation during the year. In more than one half of cases, reimbursed homeopathic preparations are prescribed in combination with allopathic medicines.

So, my impression that homeopathy is much more popular in France than elsewhere was not entirely correct. Like in most other countries, it is used by a minority; but this minority is fairly vocal and gets plenty of press coverage. When discussing homeopathy with friends in France, I have regularly discovered that they have very little understanding about what homeopathy is truly about; they seem to favour it because it is heavily advertised as a harmless solution to benign health problems. In no other country have I seen regular TV commercials for homeopathy! The ones who earn by far the most from this is, of course, the pharmacist – in France, homeopathic products can only be found in pharmacies!

Seen from this angle, the French usage of homeopathy is a triumph of profit over reason: the two most popular preparations (Arnica and Influenzinum) are not just not evidence-based (like all other homeopathic remedies), they have been shown in systematic reviews not to work better than placebos.

A recent comment to a post of mine (by a well-known and experienced German alt med researcher) made the following bold statement aimed directly at me and at my apparent lack of understanding research methodology:

C´mon , as researcher you should know the difference between efficacy and effectiveness. This is pharmacological basic knowledge. Specific (efficacy) + nonspecific effects = effectiveness. And, in fact, everything can be effective – because of non-specific or placebo-like effects. That does not mean that efficacy is existent.

The point he wanted to make is that outcome studies – studies without a control group where the researcher simply observe the outcome of a particular treatment in a ‘real life’ situation – suffice to demonstrate the effectiveness of therapeutic interventions. This belief is very wide-spread in alternative medicine and tends to mislead all concerned. It is therefore worth re-visiting this issue here in an attempt to create some clarity.

When a patient’s condition improves after receiving a therapy, it is very tempting to feel that this improvement reflects the effectiveness of the intervention (as the researcher mentioned above obviously does). Tempting but wrong: there are many other factors involved as well, for instance:

  • the placebo effect (mainly based on conditioning and expectation),
  • the therapeutic relationship with the clinician (empathy, compassion etc.),
  • the regression towards the mean (outliers tend to return to the mean value),
  • the natural history of the patient’s condition (most conditions get better even without treatment),
  • social desirability (patients tend to say they are better to please their friendly clinician),
  • concomitant treatments (patients often use treatments other than the prescribed one without telling their clinician).

So, how does this fit into the statement above ‘Specific (efficacy) + nonspecific effects = effectiveness’? Even if this formula were correct, it would not mean that outcome studies of the nature described demonstrate the effectiveness of a therapy. It all depends, of course, on what we call ‘non-specific’ effects. We all agree that placebo-effects belong to this category. Probably, most experts also would include the therapeutic relationship and the regression towards the mean under this umbrella. But the last three points from my list are clearly not non-specific effects of the therapy; they are therapy-independent determinants of the clinical outcome.

The most important factor here is usually the natural history of the disease. Some people find it hard to imagine what this term actually means. Here is a little joke which, I hope, will make its meaning clear and memorable.

CONVERATION BETWEEN TWO HOSPITAL DOCTORS:

Doc A: The patient from room 12 is much better today.

Doc B: Yes, we stared his treatment just in time; a day later and he would have been cured without it!

I am sure that most of my readers now understand (and never forget) that clinical improvement cannot be equated with the effectiveness of the treatment administered (they might thus be immune to the misleading messages they are constantly exposed to). Yet, I am not at all sure that all ‘alternativists’ have got it.

On this blog, we have discussed the Alexander Technique before; it is an educational method promoted for all sorts of conditions, including neck pain. The very first website I found when googling it stated the following: “Back and neck pain can be caused by poor posture. Alexander Technique lessons help you to understand how to improve your posture throughout your daily activities. Many people, even those with herniated disc or pinched nerve, experience relief after one lesson, often permanent relief after five or ten lessons.”

Sounds too good to be true? Is there any good evidence?

The aim of this study, a randomized controlled trial with 3 parallel groups, was to test the efficacy of the Alexander Technique, local heat and guided imagery on pain and quality of life in patients with chronic non-specific neck pain. A total of 72 patients (65 females, 40.7±7.9 years) with chronic, non-specific neck pain were recruited. They received 5 sessions of the Alexander Technique, while the control groups were treated with local heat application or guided imagery. All interventions were conducted once a week for 45 minutes each.

The primary outcome measure at week 5 was neck pain intensity quantified on a 100-mm visual analogue scale; secondary outcomes included neck disability, quality of life, satisfaction and safety. The results show no group differences for pain intensity for the Alexander Technique compared to local heat. An exploratory analysis revealed the superiority of the Alexander Technique over guided imagery. Significant group differences in favor of the Alexander Technique were also found for physical quality of life. Adverse events were mild and mainly included slightly increased pain and muscle soreness.

The authors concluded that Alexander Technique was not superior to local heat application in treating chronic non-specific neck pain. It cannot be recommended as routine intervention at this time. Further trials are warranted for conclusive judgment.

I am impressed with these conclusions: this is how results should be interpreted. The primary outcome measure failed to yield a significant effect, and therefore such a negative conclusion is the only one that can be justified. Yet such clear words are an extreme rarity in the realm of alternative medicine. Most researchers in this area would, in my experience, have highlighted the little glimpses of the possibility of a positive effect and concluded that this therapeutic approach may be well worth a try.

In my view, this article is a fine example for demonstrating the difference between true scientists (who aim at testing the effectiveness of interventions) and pseudo-scientists (who aim at promoting their pet therapy). I applaud the authors of this paper!

Lyme disease, also known as Lyme borreliosis, is an infectious disease caused by Borrelia infection transmitted by ticks. The most common early sign is an expanding area of redness beginning at the site of a bite about a week after a tick-bite. Fever, tiredness and headaches often follow. Later stages are characterised by more severe and remarkably variable illness.

Patients with medically unexplained or vague symptoms are sometimes told that they suffer from Lyme disease. These patients are commonly targeted by providers of alternative therapies who promise hope by claiming that their particular brand of quackery is effective for this chronic condition.

A recent review was designed to identify and characterize the range of unorthodox alternative therapies advertised to patients with a diagnosis of Lyme disease.

Internet searches using the Google search engine were performed to identify the websites of clinics and services that marketed non-antimicrobial therapies for Lyme disease. Subsequently the PubMed search engine was employed to identify any scientific studies evaluating such treatments for Lyme disease. Websites were included in this review, if they advertised a commercial, non-antimicrobial product or service that specifically mentioned utility for Lyme disease. Websites with patient testimonials (such as discussion groups) were excluded unless the testimonial appeared as marketing on a commercial site.

More than 30 different alternative treatments were identified. They fell into several broad categories: these included oxygen and reactive oxygen therapy; energy and radiation-based therapies; nutritional therapies; chelation and heavy metal therapies; and biological and pharmacological therapies ranging from certain medications without recognized therapeutic effects on Borrelia burgdorgeri to stem cell transplantation. The review of the medical literature did not substantiate efficacy or, in most cases, any rationale for the advertised treatments.

The authors concluded that providers of alternative therapies commonly target patients who believe they have Lyme disease. The efficacy of these unconventional treatments for Lyme disease is not supported by scientific evidence, and in many cases they are potentially harmful.

Being a bacterial infection, Lyme disease can be successfully treated with oral or intra-venous antibiotics. But, of course, patients need to have the infection in order to benefit from antibiotic treatment. Those patients who don’t are easy targets for charlatans promising help from bogus treatments. It seems that an entire, profitable industry has developed around this situation.

One of the UK’s most ardent promoters of outright unproven and disproven therapies must be Dr Michael Dixon. He has repeatedly and deservedly received a mention on this blog. Steven Novella even called him once a ‘pyromaniac in a field of (integrative) straw men’. This is because Steven felt that Dixon uses phony arguments to promote dodgy therapies. If you find this hard to believe (after all Dixon is a GP who heads important organisations such as the NHS Alliance and the College of Medicine), just look at him dabbling in spiritual healing. Unusual, to say the least, I’d say. If you want to learn more about the strange Dr Dixon, you should read my memoir where he makes several remarkable appearances.

I always delight when I stumble over something that one of my former co-workers (yes, Dixon and I did collaborate for many years) has said to the press. This is why an otherwise silly article in the Daily Mail (yes, I know!) caught my attention; here is the relevant section: Dr Mike Dixon, a GP in Cullompton, Devon, and chairman of the College of Medicine, says he is a ‘fan’ of herbal medicines because they are ‘safe, help to encourage self-care by patients and, in cases such as mint and aloe vera, can be grown by the patients themselves, making them virtually free’.

As I already pointed out, Dixon does tend to promote bizarre concepts. The generalisation that herbal remedies are safe is not just bizarre, it also put the public at risk. One does not need to search long to find an article that makes this clear:

Various reports suggest a high contemporaneous prevalence of herb-drug use in both developed and developing countries. The World Health Organisation indicates that 80% of the Asian and African populations rely on traditional medicine as the primary method for their health care needs. Since time immemorial and despite the beneficial and traditional roles of herbs in different communities, the toxicity and herb-drug interactions that emanate from this practice have led to severe adverse effects and fatalities. As a result of the perception that herbal medicinal products have low risk, consumers usually disregard any association between their use and any adverse reactions hence leading to underreporting of adverse reactions. This is particularly common in developing countries and has led to a paucity of scientific data regarding the toxicity and interactions of locally used traditional herbal medicine. Other factors like general lack of compositional and toxicological information of herbs and poor quality of adverse reaction case reports present hurdles which are highly underestimated by the population in the developing world. This review paper addresses these toxicological challenges and calls for natural health product regulations as well as for protocols and guidance documents on safety and toxicity testing of herbal medicinal products.

Dixon once told me that GPs do not any longer read scientific papers. I think, however, that he should start doing so before the next time he misinform the public and endangers the health of vulnerable people.

The task of UK Clinical Commissioning Groups (CCGs) is to ensure NHS funds are spent as effectively and responsibly as possible. This is particularly important in the current financial climate, as NHS budgets are under enormous pressure. For that reason, The Good Thinking Society (GTS, a pro-science charity) invited Liverpool CCG to reconsider whether the money (~ £ 30,000 pa) they spend on homeopathy represents good service to the public. Recently the CCG agreed to make a fresh decision on this contentious issue.

The GTS would prefer to see limited NHS resources spent on evidence-based medicine rather than on continued funding of homeopathy which, as readers of this blog will know, has repeatedly failed to demonstrate that it is doing more good than harm. It is encouraging to see Liverpool CCG take a first step in the right direction by agreeing to properly consider the best evidence and expertise on this issue.

Supporters of homeopathy frequently cite the concept of patient choice and claim that, if patients want homeopathy, they should have it free on the NHS. The principle is obviously important, but it is crucial that this choice is an informed one. The best evidence has conclusively shown that homeopathy is not an effective treatment, and to continue to offer ineffective treatments under the guise of patient choice raises troubling questions about the important concept of informed choice, and indeed of informed consent as well as medical ethics.

The GTS were represented by Salima Budhani and Jamie Potter of Bindmans LLP. Salima said: “This case underlines the necessity of transparent and accountable decision making by the controllers of health budgets, particularly in the light of the current financial climate in the NHS. CCGs have legal obligations to properly consider relevant evidence, as well as the views of experts and residents, in deciding how precious NHS resources are to be spent. It is essential that commissioning decisions are rational and evidence-based. Liverpool CCG’s decision to reconsider its position on the funding of homeopathy in these circumstances is to be welcomed.

“Our client has also called upon the Secretary of State for Health to issue guidance on the funding of homeopathy on the NHS. Public statements by the Secretary of State indicate that he does not support ongoing funding, yet he has so far declined to ask NICE to do any work on this issue. The provision of such guidance would be of significant benefit to CCGs in justifying decisions to terminate funding.”

Commenting on their decision, a Liverpool CCG spokesperson said: “Liverpool CCG currently resources a small homeopathy contract to the value of £30,000 per year that benefits a small number of patients in the city who choose to access NHS homeopathy care and treatment services. The CCG has agreed with the Good Thinking Society to carry out further engagement with patients and the general public to inform our future commissioning intentions for this service.”

Over the last two decades, prescriptions fulfilled in community pharmacies for homeopathy on the NHS in England have fallen  by over 94% and homeopathic hospitals have seen their funding reallocated. This reduction indicates that the majority of doctors and commissioning bodies have acted responsibly by terminating funding for homeopathic treatments.

In the realm of homeopathy there is no shortage of irresponsible claims. I am therefore used to a lot – but this new proclamation takes the biscuit, particularly as it currently is being disseminated in various forms worldwide. It is so outrageously unethical that I decided to reproduce it here [in a slightly shortened version]:

“Homeopathy has given rise to a new hope to patients suffering from dreaded HIV, tuberculosis and the deadly blood disease Hemophilia. In a pioneering two-year long study, city-based homeopath Dr Rajesh Shah has developed a new medicine for AIDS patients, sourced from human immunodeficiency virus (HIV) itself.

The drug has been tested on humans for safety and efficacy and the results are encouraging, said Dr Shah. Larger studies with and without concomitant conventional ART (Antiretroviral therapy) can throw more light in future on the scope of this new medicine, he said. Dr Shah’s scientific paper for debate has just been published in Indian Journal of Research in Homeopathy…

The drug resulted in improvement of blood count (CD4 cells) of HIV patients, which is a very positive and hopeful sign, he said and expressed the hope that this will encourage an advanced research into the subject. Sourcing of medicines from various virus and bacteria has been a practise in the homeopathy stream long before the prevailing vaccines came into existence, said Dr Shah, who is also organising secretary of Global Homeopathy Foundation (GHF)…

Dr Shah, who has been campaigning for the integration of homeopathy and allopathic treatments, said this combination has proven to be useful for several challenging diseases. He teamed up with noted virologist Dr Abhay Chowdhury and his team at the premier Haffkine Institute and developed a drug sourced from TB germs of MDR-TB patients.”

So, where is the study? It is not on Medline, but I found it on the journal’s website. This is what the abstract tells us:

“Thirty-seven HIV-infected persons were registered for the trial, and ten participants were dropped out from the study, so the effect of HIV nosode 30C and 50C, was concluded on 27 participants under the trial.

Results: Out of 27 participants, 7 (25.93%) showed a sustained reduction in the viral load from 12 to 24 weeks. Similarly 9 participants (33.33%) showed an increase in the CD4+ count by 20% altogether in 12 th and 24 th week. Significant weight gain was observed at week 12 (P = 0.0206). 63% and 55% showed an overall increase in either appetite or weight. The viral load increased from baseline to 24 week through 12 week in which the increase was not statistically significant (P > 0.05). 52% (14 of 27) participants have shown either stability or improvement in CD4% at the end of 24 weeks, of which 37% participants have shown improvement (1.54-48.35%) in CD4+ count and 15% had stable CD4+ percentage count until week 24 week. 16 out of 27 participants had a decrease (1.8-46.43%) in CD8 count. None of the adverse events led to discontinuation of study.

Conclusion: The study results revealed improvement in immunological parameters, treatment satisfaction, reported by an increase in weight, relief in symptoms, and an improvement in health status, which opens up possibilities for future studies.”

In other words, the study had not even a control group. This means that the observed ‘effects’ are most likely just the normal fluctuations one would expect without any clinical significance whatsoever.

The homeopathic Ebola cure was bad enough, I thought, but, considering the global importance of AIDS, the homeopathic HIV treatment is clearly worse.

The Paleo diet is based on the evolutionary discordance hypothesis, according to which departures from the nutrition and activity patterns of our hunter-gatherer ancestors have contributed greatly and in specifically definable ways to the endemic chronic diseases of modern civilization. The assumption is that during the Paleolithic era — a period lasting around 2.5 million years that ended about 10,000 years ago with the advent of agriculture and domestication of animals — humans evolved nutritional needs specific to the foods available at that time, and that the nutritional needs of modern humans remain best adapted to the diet of their Paleolithic ancestors. Today’s humans are said to be not well adapted to eating foods such as grain, legumes, and dairy, and in particular the high-calorie processed foods. Proponents claim that modern humans’ inability to properly metabolize these comparatively new types of food has led to modern-day problems such as obesity, heart disease, and diabetes. They furthermore claim that followers of the Paleolithic diet may enjoy a longer, healthier, more active life.

The Paleo Diet is alleged to work by two fundamental principles:

  •  Put the optimal nutrition into your body.
  •  Reduce or eliminate toxins and “interference”.

And what are the results, as claimed by those who promote (and profit from) the Paleo diet? The alleged benefits include:

  • Leaner, Stronger Muscles
  • Increased Energy
  • Significantly More Stamina
  • Clearer, Smoother Skin
  • Weight Loss Results
  • Better Performance and Recovery
  • Stronger Immune System
  • Enhanced Libido
  • Greater Mental Clarity
  • No More Hunger/Cravings
  • Thicker, Fuller Hair
  • Clear Eyes

Critics of the Paleo diet point towards abundant evidence that paleolithic humans did, in fact, eat grains and legumes. They also stress that humans are much more nutritionally flexible than previously thought, that the hypothesis that Paleolithic humans were genetically adapted to specific local diets is unproven, that the Paleolithic period was extremely long and saw a variety of forms of human settlement and subsistence in a wide variety of changing nutritional landscapes, and that currently very little is known for certain about what Paleolithic humans ate.

So, the theories behind the Paleo diet are flimsy and naïve; the most crucial question, however, is does it work?

Overall there is little solid evidence; unsurprisingly, some studies have shown that cardiovascular risk factors can be positively influenced, for instance, in patients with diabetes. But the more specific claims, like the ones above, are not supported by good clinical evidence.

It seems that, yet again, less than responsible entrepreneurs have jumped on a popular band-wagon to exploit the often hopelessly gullible public.
