Thoughts? Seems like the population changed a lot of variables at the same time and it wasn't well controlled nor was it under Paleo guidelines (naturally raised, healthy Omega-6/Omega-3, large amounts of vegetables, etc). The conclusion seems to be a stretch as well, as it's predicated on the cholesterol to heart disease connection. To be fair, they did say "might".

"...a 25-year study of 140,000 Swedish adults found."
Typically in a study the more data points the better but with so many people involved over such a time-span you are going to completely lose control. You're going to have the cheaters/liars, forgetfulness, people who think a Big Mac without the bun is suddenly a good idea and so on.
How did they even DO this study on 140,000 people? Ask them what they ate for the past 25 years and snag a look at their current biomarkers? No way they actually kept proper tabs on people for 25 years, so are we just basing this on what people feel like telling a stranger about their personal habits?
Methods: Cross-sectional information on self-reported food and nutrient intake and measured body weight, height, and serum cholesterol were compiled for over 140,000 observations.
DING! #1 rule about asking about one's diet or biomarkers - either they lie or they have no idea.

The study acknowledges that low carbs diets have only really been under scrutiny since 2005, and people who have been paleo for more than 5 years are probably still off the radar of most conventional nutritional studies.
Even if I believed them, which I don't, a study of this magnitude can't possibly be true of paleo people since there aren't enough of us who have been doing this long enough to provide the necessary data.
In other words, it's too soon to tell. If all of us see a spike in our cholesterol and we gain a bunch of weight over the next ten years, well then we should probably change our habits individually.
Until then, I'll bet my kettle bell that bacon fat is better for me personally than wheat bread or lentils.
I should mention that I have heard that long term ketosis is hard on the organs, and that makes perfect sense to me. Most of us eat enough fruit, squash, and sweet potatoes to avoid that.

This study was just posted on Andreas Eenfeldt's blog. It shows that those eating a 'higher' fat diet had less central obesity. That sounds great for the paleo thinking but again this was a study with selfreported numbers. I would highly question the credibility of any study of this kind, regardless of the result.

Well, right away I can discredit this study. Or, at least, declare myself an anomaly. Cutting carbs has definitely, without any room for doubt, had a dramatic profound impact on my BMI.
