New info: The original article is here: http://www.mpg.de/4338096/insulin_eating_behaviour?filter_order=L
It discusses some findings in how the insulin impacts the dopamine system, and that that reward system may trigger the compulsion to eat.
I think this kind of stuff is interesting, and wonder if any science types can find any useful implications from it. The 'nut' of the intro is:
...insulin not only acts as a metabolic signal transmitter in the hypothalamus, a fact that is already known, but also in the dopamine-producing cells of the midbrain.
This original article does NOT suggest that a high-fat diet (or any kind of diet) causes anything. It's interesting that the site I first found it on got the summary completely wrong - which Jack Kronk correctly pointed out below. My error for not tracking down the original first! THAT sloppy article is here:
The article identifies some specific pathways for how insulin drives obesity. Confirming what we already know, but any useful new implications for us?
The key conclusion:
Over the course of several intermediary steps, the insulin inhibits the transmission of nerve impulses in such a way that the feeling of satiety is suppressed and energy expenditure reduced.

CaveRat - see the thing about articles like this is that they completely annihilate any credibility they may have otherwise been able to build when they make silly statements like that (as mentioned in your question).
"Fat-rich foods make you fat".
Bam. They lost me.
Also, regardless of that, I simply cannot possibly buy in to this idea anyway. I eat lots and lots of foods that cause a significant insulin surge. I eat lots of dairy, including whole milk, butter, and whey protein. I eat lots of sweet potatoes, and white rice, and white potatoes. I do this every single day, and have for many months now, and I must be at about 9% bodyfat by now. I have a flat stomach and basically no flab anywhere. Yes, this is totally N=1, but it's not advisable to make statements that many people can easily disprove with personal testimonies. To their credit, they do title this with the word "can" in it, but still I think this article is not worth much at all.
