My boyfriend and I order meat from a butcher once a month. I stop by the farmer's market once a week, and before the season is over, we'll stock up on root vegetables for winter storage. They'll stay in the fridge. I also buy my eggs at the farmer's market, but there's a small grocery in walking distance I could buy them at as well.
Once every two months we go to the grocery store to stock up on household things, spices, butter, coconut oil, fish, that sort of stuff.
It's actually a lot easier than when we were eating SAD, because I don't need to plan recipes and shopping list ahead of time. All I do is buy the meats at a good price, some vegetables, and cook them up!
I eat breakfast and lunch, my boyfriend eats 3 meals. I make easy soups for breakfast which I keep in mason jars in the fridge. I also keep any leftover meat. So he always has something he can microwave for brekfast.
I on the other hand, do the leptin reset, so I make myself eggs, and sometimes eggs and meat.
For my lunch, I cook a meal. The leftovers become his dinner, and his lunch the next day, which he takes to work.
Super easy! But I work from home so... for those who don't have much time, you might cook meats and soups once or twice a week, even pre-cut vegetables. Then just grab the meat for the day, cook up the vegetables. I think that's what I would do.
