Is Diamond Naturals low carb/low phosphorus?

I need help determining if this is a good choice. I'm looking for low carb and low phosphorus. This is what I received back from Diamond Naturals but I don't know what the percents mean. I have been using the indoor cat hairball formula. I didn't see this food on the spreadsheet.
