Actually, I agree the last study looks ok. The problem is it's about a completely separate discussion.
It's about MUFA, which nobody is talking about. Fully saturated fat is the recommendation.
I don't think there's actually much debate the old recommendation to guzzle olive oil was garbage. The problem is people are still advising against butter and bacon, which is wrong.
An issue with the study is they're claiming a diet that's over half carbohydrates is "high fat". No, over 60% fat would be high fat.

I'm pretty sure that's not the case. While there may be additional effects, the general results strongly suggest that barring pre-existing health conditions, it seems very likely that a modestly restricted diet and regular exercise is the best way to lose weight known to modern science.
And keep in mind: specialty diets don't work. So even if we do discover some clever metabolic hacking that lets people lose weight fast, it's not of much value to the discourse at hand about public health. People can't maintain diets.
What does the fifth study cited (http://www.ncbi.nlm.nih.gov/pubmed/20670466 -- note that the link provided in the original post is wrong) have to do with carbohydrate-restricted diets? Carbohydrate restriction makes no appearance in the study.
You don't think there's a difference between downing a cup or two of olive oil a day vs a stick of butter? That's a huge difference. They're chemically very different things.
You don't think eating two sticks of butter a day vs one stick of butter plus half a loaf of bread is different?
> People can't maintain diets
People can easily maintain high saturated fat diets. They can't maintain calorie restricted diets.
You'll get zero debate from me there's not really a quick hack and a key component of the obesity epidemic, perhaps the single biggest issue, is that people are lazy and gluttonous. But the fact remains the obesity epidemic exploded immediately after saturated fat as a percentage of calories came way down. Fructose is the other factor; it went way up.
