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.
I bet Walmart is working hard at introducing more low carb things. Our Walmart has Lecarb ice cream and several varieties of shakes, candy bars, etc... I have also noticed an increase in pre-cooked, pre-packaged meats like chicken and roast. Hormel's precooked roast is awesome and not too expensive. It is only about a $1 more a pound but it saves a lot of time.
