Though the authors of this e-book definitely promote a message that they consider is scientifically legitimate and helpful and though a really massive variety of individuals agree with them, I take exception, for a number of causes. With minor exceptions this e-book represents nothing greater than an extension of the arguments for the Atkins eating regimen. Thus my feedback relate to what I consider to be improper with these arguments.
There are quite a few situations the place the authors’ misuse scientific proof. In fact, they’ll disagree as a result of they’re claiming fairly the alternative, particularly, that their e-book highlights a rising physique of scientific proof now supporting the Atkins eating regimen, a place additionally publicized on the Atkins web site. Trivializing and advertising the science started early with the Atkins group, beginning with Dr. Atkins himself who had no use for the scientific methodology. In line with his widow, he was proud that he by no means revealed a single peer-reviewed scientific paper. That is dramatically opposite to skilled scientists on this discipline who’ve revealed no less than dozens, even lots of of papers that, MOST IMPORTANTLY, are subjected to crucial evaluate by friends. Thus, Atkins’ fanatics rely far more on private testimonials and anecdotal reviews for his or her arguments. This sort of proof needn’t be solely dismissed however, with out systematic and clear group of scientific analysis that’s critiqued by certified friends, it is rather onerous to validate claims. The give and take of peer evaluate, for instance, is totally demanded for claims being made about private well being, particularly when these claims are meant for big segments of the general public.
Extra particularly, the authors attempt to persuade the readers into believing that the science ‘institution’ has lastly begun to validate this eating regimen on a large scale, however that is merely not true. The authors, for instance, spotlight within the introduction that “in the previous few years greater than fifty fundamental and utilized research have been revealed which, along with validating the security and effectiveness of the Atkins Food regimen, additionally present new insights into methods to optimize the Atkins life-style.” For many readers, this means, based on the authors, that there are 50 research that doc the prevalence of the Atkins eating regimen over different dietary methods that may be thought-about for a long-standing dietary life-style. However, in Chapter 1 they considerably paradoxically say that there are 7 research (solely) lasting 6 months to 2 years that evaluate the Atkins eating regimen with “different widespread weight reduction methods”, a time thought-about by them to be long-term. However, in actuality, this time nonetheless falls far in need of the life-style of a few years that they advocate for utilizing this eating regimen.
They illustrate a so-called long-term impact by citing a examine finished in Kuwait that highlights the magnitude of the well being advantages that may be achieved with a “low carb” eating regimen (<20 g/day, later adjusted to 40 g/day). This examine definitely improved medical lipids and lowered physique weight (a median lack of 60 kilos). However the authors of this new e-book fail to inform the readers that this Kuwaiti eating regimen was extraordinarily low calorie, containing solely about 970 energy per day for topics weighing, on common, 235 kilos with a physique mass index (BMI) of 39. Any eating regimen this low in energy, no matter its dietary composition, will scale back physique weight like this. Omitting this info, the authors of this new e-book then go on to state that, with teaching of the topics for a 12 months, “this eating regimen outperformed that of any of the randomized teams within the different seven research.”
Realizing nothing in regards to the different 7 research, the reader should then settle for at face worth the prevalence of the Atkins eating regimen alleged by the authors. That is an unacceptably superficial method to evaluate the findings of those research. The reader is entitled to know whether or not the load losses of those a number of completely different research have been in contrast on an absolute or relative scale? Whether or not extreme calorie restriction was a part of these different research? Whether or not these comparisons have been statistically important? Whether or not the baseline weights for these research have been completely different? Whether or not there have been constant adjustments within the varied lipid biomarkers? With out this info, it’s not acceptable to make such a brash and sweeping conclusion that the Atkins eating regimen “outperformed” another eating regimen group.
I do know one thing about these different research mentioned to verify the prevalence of the Atkins eating regimen, particularly the examine that the authors listing first of their e-book and repeatedly cite of their listing of references. It is a examine by Gardner et al at Stanford College that was revealed within the Journal of the American Medical Affiliation in 2007. The issues on this report are critical and are sometimes repeated in different research on the Atkins eating regimen. Of much more concern was the fast and widespread media recognition shortly given to the findings of this Gardner et al examine. Main headlines have been revealed throughout the nation in a method to lead most individuals to consider that the Atkins examine had lastly made the grade as a superior eating regimen. Now, on this new e-book, the findings of this Gardner et al examine seem as soon as once more, this time being repeatedly cited as proof of excellent science.
As a result of the Gardner et al examine had critical flaws and was destined to create main media remark, it subsequently required critique on the time it was revealed. Conventionally in science, after publication of a examine, that is initially finished utilizing a extensively accepted, letters-to-the-editor format that may be thought-about as an extension of the peer-review course of. 4 of us within the occupation subsequently duly submitted our letters to the editor of JAMA to level out these flaws and to hunt the investigators’ feedback. More often than not, such letters, after some modest peer evaluate, are routinely revealed, however not on this case.
In my letter, the flaw that I discovered particularly repugnant–and apparent–was their comparability of the Atkins eating regimen outcomes to the low fats, plant-based eating regimen of Dean Ornish pejoratively referred to as “extraordinarily low” by the researchers. The unique Ornish eating regimen–and different related diets– comprises solely 10-12% fats like different complete meals, plant based mostly diets however Gardner et al inappropriately examined a grossly distorted “Ornish eating regimen” that contained 29% fats! So as to add additional insult, they referred to as this falsely fabricated eating regimen “extraordinarily low in fats”. The distortion of the eating regimen was much more critical as a result of the Gardner model of the ‘Ornish’ eating regimen contained 18% protein, which is 70-80% greater than the quantity really helpful and which is often present in Ornish sort diets. Fats and protein collectively comprised 48% of the Gardner model of the eating regimen, reasonably than the 20-22% often seen in complete meals plant-based diets. Within the Gardner examine, there truly have been two extra diets being in contrast and, collectively, these 4 diets have been nutritionally very related (no less than when put next with a very low fats, complete meals plant-based eating regimen), thus severely limiting the power to detect significant and statistically important variations. Nonetheless, a non-significant barely decrease physique weight was noticed for the Atkins eating regimen and this made headlines as if it was actually vital.
I’ve revealed many papers from our laboratory and have served on a number of science journal editorial evaluate boards. By no means have I witnessed such unprincipled conduct as that of the JAMA editor when he denied all 4 of our letters, particularly a letter from Dr. Ornish whose examine was being so grossly misrepresented. Readers had a proper to listen to a response from the investigators however this was not forthcoming, because of the JAMA editor. It was as if somebody had wished these Gardner findings revealed and publicized, no matter its flaws. It’s as if the funding of the examine, the design of the examine, the interpretation and dialogue of the outcomes, the pre-publication evaluate of the manuscript, the refusal to publish our post-publication letters and the media reporting of the findings have been script from a well-designed advertising plan. Now, three years later, the authors of this new e-book, who appear oblivious to the issues of this examine, herald it as vital proof serving to to show the prevalence and widespread applicability of the Atkins eating regimen.
This follow of Atkins eating regimen researchers of creating improper eating regimen comparisons like this has occurred far too usually. Because of this, unsubstantiated claims are repeatedly made and dressed up pretty much as good science. Much more confounding on this historical past is the repeated misuse of phrases and phrases that outline excessive and low quantities of fats and carbs. New phrases (like ‘carbs’) with nebulous meanings are created. Improperly outlined benchmarks of ‘excessive’ and ‘low’ dietary ranges of fats and carbohydrate are used that vastly confuse comparisons with different dietary methods.
Atkins himself appears to be the primary to have developed the now extensively used time period ‘carb’. I’m of the sturdy opinion that this was a contrived advertising phrase that was initially meant to query the suggestions being made at the moment to eat extra complete greens, fruits, legumes and grains. Generalizing the so-called dietary benefit of ‘low carb’ diets had the impact of diminishing the well being worth of those plant-based meals as a result of these are the one complete meals that comprise carbohydrates. Though newer makes an attempt are being made to differentiate ‘dangerous’ carbohydrates from ‘good’ carbohydrates by superficially ‘counting carbs’ (as if these are entities that may be counted!), this nonetheless stigmatizes the distinctive well being worth of an entire meals, plant-based eating regimen. Just about anybody of any scientific substance throughout the previous half-century has identified that comparatively easy (‘dangerous’) carbohydrates like sugar and refined flour, trigger well being issues. However this doesn’t imply that we are able to generalize this huge and sophisticated class of nutritionally precious carbohydrates, as present in complete plant based mostly meals, right into a single class referred to as ‘carbs’, then demonize the superior dietary worth of those excessive carbohydrate meals.
I’ve many different considerations with this e-book as to its scientific credibility, too many to doc right here. Their dialogue on protein, nevertheless, deserves consideration due to the not so apparent however nonetheless pivotal function of this nutrient when justifying the Atkins eating regimen. The authors’ protein dialogue not solely sends the improper message and is extraordinarily superficial, but in addition it’s factually improper. For instance, they emphasize that the RDA (about 8-10% of complete eating regimen energy) for protein “displays the minimal, not the optimum, quantity of protein a median wholesome particular person wants.” Improper. The RDA is just not and was by no means meant to be the minimal quantity of protein wanted. The RDA is about 2 normal deviations above the minimal every day requirement (MDR) in order to insure that the minimal necessities of just about all individuals are being met. (If all individuals theoretically consumed the RDA stage of protein, about 98% of them could be consuming in extra of their wants!) The authors’ notion that the RDA is a minimal requirement encourages, in impact, a better than crucial consumption of protein. It is a clear bias favoring greater protein consumption (that means animal-derived protein) that then extends to additional feedback by the authors that plant protein is, in impact, inferior to animal protein (1) as a result of it’s “incomplete” and (2) as a result of it doesn’t “satiate” as properly, thus suggesting, within the authors’ view, the necessity for nonetheless extra oil/fats to this already excessive fats eating regimen.
And at last, they advocate 20-25% dietary protein, then declare considerably defensively, that this isn’t a excessive protein eating regimen. That is nonsense. The current vary of dietary protein for the overwhelming majority of the inhabitants is about 11-22% of energy (common of 17%), with three-fourths of this protein offered by animal-based meals. The Atkins advice for dietary protein is triple that of the RDA, excessive by anybody’s normal (apart from these authors!). An entire meals plant-based eating regimen of blended greens, fruits, legumes, grains and tubers can simply present the RDA of about 8-10% dietary protein, based mostly on lengthy established experimental proof (since 1943) that that is greater than sufficient protein. Rising protein above the RDA of 8-10% as much as a median of 17% is mostly obtained by consuming rising quantities of animal-based meals. Moreover, rising dietary protein from about 10-12% to twenty%, for instance, ultimately will increase threat for most individuals for a lot of illnesses and situations too quite a few to debate right here. These embody critical illnesses like most cancers, coronary heart illness, osteoporosis and sure autoimmune illnesses, in addition to an awesome variety of explanatory mechanisms. The authors talked about none of those well being issues related to the excessive dietary protein of the Atkins eating regimen. Like a home of playing cards, a eating regimen ever greater in animal protein-based meals, often together with greater dietary fats (the standard Atkins advice) results in early loss of life and incapacity ensuing from the illnesses that kill most of us within the U.S. earlier than our time.
The most important drawback with this e-book goes properly past the quite a few particular errors dedicated by these authors. It’s the misguided Atkins eating regimen paradigm into which this e-book is inserted that could be a far more ominous drawback.
Most individuals agree that there are well being issues with the usual American eating regimen (SAD), which, on common, is 17% protein and 35% fats (totaling 52%), leaving 48% for carbohydrates. The Atkins eating regimen rightly recommends decreasing the ‘dangerous’ carbs however primarily by changing these ‘carbs’ with rising protein (30%) and fats (40%) (totaling 70%) thus compromising an already low consumption of extremely nutritious carbohydrate-rich plant-based meals. Inside 10 years or much less, I predict that most individuals utilizing the Atkins eating regimen will both stop or expertise critical well being issues, though many might even see extra well being advantages than hostile well being results within the brief run. The nomadic Masaai of jap Africa who eat massive quantities of meat, milk and eggs, incur like previous American males, in depth atherosclerotic lesions regardless of their in depth strolling.
The identical decreased consumption of ‘dangerous’ carbs advocated by Atkins’ individuals, will be simply achieved by an entire meals, plant based mostly eating regimen however not by rising fats and protein however by rising the consumption of complete meals, plant-based eating regimen that comprises the numerous antioxidants and sophisticated carbohydrates (e.g., fiber). This concurrently avoids extreme intakes of protein, fats and dangerous ‘carbs’ (like sugar and refined flour) whereas enhancing the consumption of the extremely nutritious complete meals, plant-based meals. There may be far superior to changing the ‘dangerous’ carbs with fats and protein, principally from animal-based meals, that comprise little or no antioxidants and sophisticated carbohydrates.
Lastly, the authors on this e-book are dedicated to discovering scientific proof that encourages individuals to eat meals of private selection (good advertising technique!), typically that means excessive fats, excessive protein based mostly meats, milk and eggs. This pleases many individuals who like to listen to good issues about their dangerous habits, however this can be a technique that may critically bias scientific objectivity. It needs to be famous that fats, salt and sugar are acquired tastes and, for fats and salt, there may be convincing proof exhibiting that inside a month or so, these addictions will be reversed whereas new and more healthy style preferences emerge.
This brings me to my closing query, particularly, why do many Atkins-oriented individuals personally accustomed to excessive fats, excessive salt and excessive protein diets adamantly refuse each to personally strive an entire meals, plant-based eating regimen and even refuse to find out about its extraordinary well being advantages? A partial motive for this can be that they don’t notice that style preferences can markedly change. It’s irresponsible for scientists and would-be scientists to dismiss health-promoting scientific proof merely to please companion readers and listeners (is that this due to the lure of cash?). I deeply honor, above all else, individuals having the precise to decide on however I strongly reject withholding info that will help their making sensible selections for themselves.
I used to be initially inclined to provide a 2 rating for this e-book–to acknowledge the authors’ effort to encourage individuals to cut back their consumption of ‘dangerous carbs’ (to make use of their phrases), however the treatment supplied by these authors is so critically misguided that I lastly determined {that a} rating of 1 is definitely too beneficiant.
