I don't think that low-carb will fully protect you from high-PUFA. Here is a study I found a while ago comparing a low-carb diet high in SFAs (60%) to a low-carb diet high in PUFAs (60%). MUFAs were kept constant at 25% of fat.

These diets were 70% fat, 15% carbs, and 15% protein. The authors noted some problems with the high-PUFA diets, like nausea, which was "significantly higher in the POLY group." They also found that PUFAs caused more severe symptoms of ketosis, which they concluded was good. (I disagree with them.) If I was eating low-carb, I would focus on beef (raw or rare), cheese, butter, coconut oil, macadamia oil, 85% dark chocolate or cocoa butter, and other fats that are very low in PUFAs. This study tells me that PUFAs don't burn clean and they generate more toxic byproducts than SFAs.
