Pity the poor lipophobes and statinators.  They’ve just taken another grievous wound to their favorite theory and haven’t even got sense enough to know it.  In fact, not only do they not have sense enough to realize they’ve taken the hit, they’re actually crowing about it.

The current issue of the Journal of the American Medical Association (JAMA) has an article titled Trends in High Levels of Low-Density Lipoprotein Cholesterol in the United States, 1999-2006 that puts another major dent in whatever validity remains of the lipid hypothesis of heart disease.

I’m going to start categorizing the types of findings published in this paper under the rubric of The Statinator Paradox.  I find it interesting that whenever scientists discover data that shows the opposite of what their hypotheses predict, they don’t conclude that their hypotheses might be wrong; instead they deem the contradiction a ‘paradox’ and bumble on ahead with their hypotheses intact.

The video below shows Chris Gardner, Ph.D., researcher from Stanford University, giving a presentation about the data he generated when he compared the Atkins diet to the Ornish diet, the Zone diet and the LEARN diet.  You all probably remember this study, which he published in JAMA in 2007, showing the low-carb diet brought about greater weight loss and better lab value improvement than the other three diets.

As you watch this long video (and you should watch it; it’s extremely entertaining and filled with a ton of good info), there are a few things you should note.

A paper appeared recently in the prestigious Proceedings of the National Academy of Sciences (PNAS) that seems to have a whole lot of people on edge.  If you read the press accounts of this study, you might think anyone stupid enough to follow a low-carb diet would be doomed to certain death from heart attack.  But is that the case?  Or is it simply another instance of the media either failing to understand how science works or, worse, misreporting to get a better story?

I suspect the latter, but before we get into it, I need to go over a few blog housekeeping issues.

As I’m sure everyone has noticed, the look of this blog has changed – as has the look of the entire website.  Our designer and tech guys have been struggling to get everything working right, but, finally, my incessant whining got to them, and they went ahead and put the thing up in its not-completed state.  Please bear with us – it will ultimately work as it’s supposed to.  If you are having a problem, send me a description in the comments section.  Make sure you tell me what kind of computer you’re using (Mac (Intel or pre-Intel)  or PC) and which browser (Firefox, Internet Explorer, Safari, etc.) so that the gurus will know what to do to fix it.

Instructor teaches Friedewald equation and bad cholesterol

This week sees the publication of yet another study showing the superiority of the low-carbohydrate diet as compared to the low-fat diet.  This study, published in the prestigious American Journal of Clinical Nutrition, demonstrates that subjects following the low-carb diet experience a decrease in triglyceride levels and an increase in HDL-cholesterol (HDL) levels; and that these changes are accompanied by a minor increase in LDL-cholesterol (LDL), which prompts the authors to issue a caveat.

Yes, although just about all the parameters that lipophobes worry about improved with the low-carb diet, the small increase in LDL has caused great concern and has prompted the authors to gravely announce that this small increase is troublesome and should be monitored closely in anyone who may be at risk for heart disease.  Since most people who go on low-carb diets do so to deal with obesity issues, and since obesity is a risk factor for heart disease, it would appear that this small increase in LDL often seen in those following a low-carb diet could put these dieters at risk.  Does it?  We’ll see.
