Protein Power is the site of Dr. Michael Eades, who writes about low-carb diets, nutrition science, and flaws in observational studies.
HN commenters point to it as a gateway to low-carb thinking, including its posts on observational studies and a critical review of Taubes' book.
Research? Sort of. Experience? Yes.
Owsley "The Bear" Stanley, the famous LSD manufacturer and Grateful Dead sound engineer, lived very healthily on an all-meat diet for over 50 years. (Note: he did have cancer, though likely due to HPV and years of secondhand cigarette smoke and firsthand marijuana smoke, and his diet probably helped him survive it, and he had a heart attack, but that was likely due to complications from his youth that became noticeable after putting on 30 pounds of muscle weightlifting in his 50s.) He posted all about it on a forum years ago. It's a very interesting read: http://activenocarber.myfreeforum.org/ftopic22-0-0-asc-.php
Traditional Inuit also eat an all-meat diet with lots of fat. See Weston Price's Nutrition and Physical Degeneration (http://gutenberg.net.au/ebooks02/0200251h.html#ch5), as well as the writings of Vilhjalmur Stefansson (http://highsteaks.com/carnivores-creed/vilhjalmur-stefansson/ ).
The Plains Indians, as well. See "Guts and Grease: The Diet of the Native Americans" (http://www.westonaprice.org/health-topics/guts-and-grease-the-diet-of-native-americans/) and this talk by Stephen Phinney, "The Aboriginal Argument" (https://www.youtube.com/watch?v=ayf4R-y_RYo). Phinney himself has been on a very low carb, ketogenic diet for, I believe, two decades.
Some argue the Inuit were not ketogenic (http://freetheanimal.com/2014/03/reiterate-elevated-ketone.html), but they tend to overestimate how long glycogen remains in muscles after…
Dr Michael Eades is a good gateway toif you're interested. He wrote a book a while ago now titled Protein Power [1], I think he is working on an update/sequel as well.
At the high level, my basic claim is that the idea that dietary saturated fat directly leads to heart attack is incorrect. The history of this claim dates back to President Eisenhower. After having a heart attack while in office he wanted to tell the public how he could avoid the same fate. Researchers cut corners to meet political targets, ignoring data that disproved their hypothesis and claimed that plaque found in cadaver arteries was made of saturated fats and that it got there due to the person's diet.
The claims weren't backed up by the studies used and we were told that this was now a known fact when it wasn't. We've spent many decades since avoiding saturated fats in favor of unsaturated fats, which are highly oxidative and have concerning side effects when run through the Krebs Cycle.
Dr Eades also has a few interesting talks on the subject when he walks through the Krebs Cycle and the difference of saturated and unsaturated fats in case that's helpful. I think [2] is one I watch years ago, though he has other similar talks on YouTube as well.

It's true that obesity is a growing problem, and it is likely also true that nearly all cases of type II diabetes can be prevented with dietary changes. But, the article repeats the 'reduce saturated fat' meme, which lately has been called into question.

I read GCBC about two months ago; although I've been interested in health & nutrition for several years now, it's amazing that I never understood how badly science has been mistreated by nutritionists & health experts.
Moreover, because this advice runs so contrary to conventional dietary wisdom, many in the community are fascinated by reviewing studies for strengths & flaws (in the similar spirit of code-reviews); consequently, I've learned more about both human physiology and the scientific process in the past few months than my entire life (which is beneficial regardless of whether or not I continue down the low-carb path).
For example, compare the quality of minds at work in the following post (it takes off in the comments):

Here's another example:
http://www.proteinpower.com/drmike/saturated-fat/abcs-big-meal-propaganda/
http://www.proteinpower.com/drmike/statistics/observational-studies-2/
"Researchers doing observational studies have much the same problem. They try to think of all the differences between two large populations of subjects so that they can statistically negate them so that only the observation in question – the vitamin C level in the example above – is different between the groups. Problem is they can never possibly think of all the differences between the groups. As a consequence, they never have a perfect study with exactly the same number, sex, age, lifestyle, etc. on both sides with the only difference being the study parameter. And so they don’t really ever prove anything. In fact, we would all probably be a lot better off if all the researchers doing observational studies had followed my lead and fallen asleep mid study."
