I’m not entirely sure what your concept of a ketogenic diet is. Ketogenic diets are simply means to cut down carbohydrates, and increase fat intake. I’m not entirely sure what type of information you’re looking for to ‘dissuade’ you from other opinions. Studies are not meant to ‘dissuade’ anyone, they’re meant to provide insights into the new frontiers of whatever is being studied. I would have a hard time responding to that with respect to what recommendations or opinions that you are saying that are contrary to my own. That said, based on the tone of your first paragraph, you can find in any sort of information whatever type of conclusions you wish to pull from any study if you’re approaching them with your own personal biases.
Also, if you consistently rely on ‘expert opinion’ instead of being able to educate yourself in how to read unbiased evidence that ‘experts’ get their support from – then I can safely say that you will never free yourself from biased information. Experts get to where they are in large part due to the fiscal draw of their own positions, and end up making money supporting their own ideologies. They easily disregard unbiased information that go against their core beliefs, and easily attach themselves to those who may or may not be biased to those that agree with their own views – similar to the approach you’re taking with your commentary.
I would consider myself a zealot insofar as that I know this can benefit people – the question would be simply bias. I put that as my name as a full disclosure that I am for this particular diet. Do I make any money out of this? No. Have I published any books that would benefit me in any way? No. The experts you’re touting do. To your point that I haven’t provided a modicum of evidence is frankly insulting considering you have not provided any evidence at all to support your points except for the single study at the end of your commentary, and yet have the gall to say that I’m the one who has not provided any evidence and it’s only you that choose to disregard the ones I’ve provided.
With regard to your single study that you’ve provided, here are my insights and opinions:
There have been 3 key historical impetuses that has created such a prevalence and therefore a perceived requirement of carbohydrates in the north american diet – starting off with the food shortages shortly after WW2, the Ancel Keyes studies sponsored by the USDA in 1969, and then the banning of low-carb labelling in 2004 in Canada due to a large financial lobby from the sugar and agricultural industries. You can research these individually but these are key things to keep in mind for the following.
My first comment to this would be a question of why you’re quoting a single study published in 2006, which reads into the progression of understanding of knowledge stemming back from 1958 up until 2004. The conclusions and RECOMMENDATIONS from this study are based on information published from the late 90’s to 2004. Since 2004 and the ban of low-carb labelling in Canada, a significant burst of research has been started and completed (including decade-long studies that were started in the late 90’s as well) that have tried to isolate the key points of support that low carb does have practical and significant beneficial effects in human physiologies. Since then, the studies I’ve provided to you have all pointed to the links of various metabolic diseases – even the ones that were funded (and subsequently tried to be buried) by the sugar industry, the USDA, the American Heart Association (+ The Heart and Stroke Foundation in Canada), showed significant results towards the ill-health effects of carbohydrates in the diet.
So in large part, I don’t care as much about what kind of imprimateur is on a study – that only leads me to bear in mind what kind of biases were set going into the studies. The sources I’ve quoted are largely from academic foundations (Cambridge, British Journal of Nutrition, John’s Hopkins, etc.) as opposed to a singular organization who has a blatant bias at proving that their previous recommendations were not wrong. Since the studies that have recently been released, the USDA has since changed their stance on the food pyramid – cutting down recommendations on their ‘My Plate’ system, which I have no doubt within the next 2 decades, will continue to minimize the role of carbs in the human diet.
Sorry for the long rant, but I’ve encountered people that have such convictions based on their encounters with expert opinions (some even touting TV celebrities like the Doctors or Doctor OZ), without being able to comprehend where their information is coming from. Frankly if looking at unbiased academic studies isn’t enough to make you think twice about your own personal convictions, I don’t think anything will.
