I don't know how you do it. If the atkins people were smart, they would be looking into this right now, however they were slow to the product race. Many companies like carborite, KETO and so on were much faster to start putting products on the market.
I know there are companies that sell by mail frozen locarb meals but they are pricey. You can find them HERE I suppose someone would have to start from scratch, but I'll bet that the frozen food giants will get on this bandwagon soon, lets hope.
