Anabolic diet comes to mind which I only know a smidgin about. I'm not sure about training with lots of metcon on so little carbs but I know next to nothing when it comes to nutrition.
I think it was basically 5 days of less than 50g/d carbs with carb load on the weekend. Sounds like it might be ok for strength training but again, I dunno. As we used to say in philosophy...B'dunno.
