Well, we drink almond milk mostly, and it keeps for 2 weeks. A lot of our meat is frozen unless we're planning a special meal. Some fruits and veggies are a bit tricky, sometimes we make a quick trip to get some fresh produce, but between some produce keeping well on the counter, and others in the fridge, they last a week or so.

Bread keeps long enough, unfortunately thanks to preservatives. "Homemade" (can't believe that label is allowed on factory-made food here) bread lasts a little longer in the fridge. But all bread I know freezes well, so we thaw it when we're ready to it the loaf, and it's gone within a few days.

We also live in a dry climate in the mountain west. I don't think we could get away with this in a wet climate.
