The thing to remember when you see a headline like this about an observational epidemiology study is that you're basically looking at educated superstition. The authors can go to great lengths to remove all of the confounding factors they can possibly think of, but ultimately the best they can do is show a correlation. And almost every time a follow-up interventional study will fail to demonstrate a causal relationship. (Full disclosure: I've been eating relatively low-carb for about 15 years and in the last two years reduced my intake even further. I'm currently by far the leanest I can remember being, despite being just a few pounds shy of the heaviest I've ever been).
