@BillyBob--Anecdotal evidence is not science. And the scientific jury is still out about butter, though trans fats have been proven harmful, thanks in large part, to the efforts of Walter Willett, MD and nutrition researcher at Harvard ("Eat, Drink, and Be Healthy").
Oh, I was not trying to present science, I'm just stating my personal experience(anecdote), as well as the experience of my friend, for a study of 2(N2). But, of course, there are others with studies out there that claimed it would work in that fashion, which it turned out it did for us, so good enough for me. But I would never try and convince others to go that route, heck I rarely do it myself--- just giving my anecdotal past experience FWIW. Still, if one wanted to research it, a fair amount of evidence could be found. But of course there are probably not going to be any large scale studies of the types that some folks require in order to listen to a claim.
But I would be interested to know if there is any more scientific evidence for Ornish or whatever than there is for what I did for my anecdote? In the mean time there is no doubt that, even though the jury might still be out on butter, it- as you say- is in for transfats, and no doubt that this was pushed on us by the scientific community and that good old conventional wisdom for 30 years. Do any of Y'all recall when McDonald's was badgered, back around 1990, into stopping their tradition of frying in Lard and switched to soaking their fries in transfats? I think everyone, all of the authorities, knew that had to be healthier, though I doubt they had the science to prove it.
I'm not trying to discourage a vegan or Ornish type approach. I am saying that there are studies both ways, as Prato says making it hard to know what the science actually proves. As usual. However, I can add 2 anecdotes to the studies that support low carb. At least in the parameters that were measured as mentioned in my previous post, no nutrition approach could beat- and would be lucky to touch- our results, and
for myself I will happily accept that evidence. Again though, I am only referring to the parameters I already mentioned, which is not to say it might not be harmful in some unmeasured way.
Speaking of science, here is a quick randomized trial I found comparing a LCKD=Low carb ketogenic diet vs O+LFD= prescript
ion drug orlistat+ Low fat diet in the battle against high blood pressure, a major cadiovascular threat to health. Again, let me emphasize, this is pitting one diet PLUS prescript
ion drug(with probable/possible SEs) against just a diet. And a type of diet that I have often heard is bad for you at that:

The LCKD had a more beneficial impact than O + LFD on systolic (-5.9 vs 1.5 mm Hg) and diastolic (-4.5 vs 0.4 mm Hg) blood pressures (P < .001 for both comparisons). High-density lipoprotein cholesterol and triglyceride levels improved similarly within both groups. Low-density lipoprotein cholesterol levels improved within the O + LFD group only, whereas glucose, insulin, and hemoglobin A(1c) levels improved within the LCKD group only; comparisons between groups, however, were not statistically significant.
CONCLUSION:
In a sample of medical outpatients, an LCKD led to similar improvements as O + LFD for weight, serum lipid, and glycemic parameters and was more effective for lowering blood pressure.
WOW! The low carb diet
was more effective for lowering blood pressure. than was the drug + low fat diet. Plus "LDL improved ONLY in the O+LFD group, whereas glucose, insulin, and hemoglobin A(1c) levels improved within the LCKD group ONLY" though apparently not significantly between groups in either any case.
I'm surprised that was not headline news with at a minimum huge demands for further studies, I wonder why it wasn't? Interestingly, this study matches my personal anecdotal study N2, except my results were even better as my BP stopped rising and came down from 140/90+ to 110/60. EDIT: question. Does "systolic (-5.9 vs 1.5 mm Hg) and diastolic (-4.5 vs 0.4 mm Hg)" mean that BP actually increased very slightly after 48 weeks of the drug + LFD?
Here is a study of old fashioned conventional low-calorie, high nutritional value diet(LCD) vs low-carbohydrate ketogenic diet (LCKD):
www.ncbi.nlm.nih.gov/pubmed/22673594Somebody said...
METHODS:
Three hundred and sixty-three overweight and obese participants were recruited from the Al-Shaab Clinic for a 24-wk diet intervention trial; 102 of them had type 2 diabetes. The participants were advised to choose LCD or LDKD, depending on their preference. Body weight, body mass index, changes in waist circumference, blood glucose level, changes in hemoglobin and glycosylated hemoglobin, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, uric acid, urea and creatinine were determined before and at 4, 8, 12, 16, 20, and 24 wk after the administration of the LCD or LCKD. The initial dose of some antidiabetic medications was decreased to half and some were discontinued at the beginning of the dietary program in the LCKD group. Dietary counseling and further medication adjustment were done on a biweekly basis.
RESULTS:
The LCD and LCKD had beneficial effects on all the parameters examined. Interestingly, these changes were more significant in subjects who were on the LCKD as compared with those on the LCD. Changes in the level of creatinine were not statistically significant.
CONCLUSION:
This study shows the beneficial effects of a ketogenic diet over the conventional LCD in obese diabetic subjects. The ketogenic diet appears to improve glycemic control. Therefore, diabetic patients on a ketogenic diet should be under strict medical supervision because the LCKD can significantly lower blood glucose levels.
This again is similar to my anecdotal experience, in that all parameters studied were improved, and more so with the LCKD. Plus, notice "some antidiabetic medications was decreased to half and some were discontinued at the beginning of the dietary program in the LCKD group.". What? They were able to reduce or do away with drugs for type 2 diabetes by just switching to a low carb diet? So they improved or cured type 2 diabetes with this diet? I am also surprised that is not big news.
But like I said earlier, no doubt there are studies, and science, somewhere, that show the opposite. But this science matches my experience, so I will go by that. But that's just me.
