Food Theory: How Long Could You SURVIVE Locked In A Grocery Store?
SUBSCRIBE to NEVER Miss a Food Theory! ►►
I've seen the videos Creators posted about trying to live for 24 hours in a grocery store or places like Target. That got me thinking. How long COULD you survive in a grocery store? Whether you were locked in or it was your home base in a zombie apocalypse, how long would you be able to SURVIVE with that as your only source of sustenance? Today, I'm going to settle in and find out!

    Everything after 10:50, is insane. I mean the whole idea is somewhat of a tangent but he clearly saved the stupid stuff as extra for anyone dumb enough to still be watching after ten minutes.

    I was waiting for him to say farming :)) There is a flower section in most of the store. Depending on your store.. if not rip lmao.. also raw food can be dehydrated in a vacuum bag to extend its spoilages like the astronaut food.

    how long dose food last like milk :D

  • 1SLUGGO1

    Considering there are emergency exits in grocery stores, you'd be pretty stupid to spend more than a few minutes in a locked one. You literally cannot be "locked-in" to a commercial space because the locks are on the inside.

    how long can you last in pizza hut

    or... you know.. just throw a can of something at the door and get out...

    Also, assuming the grocery store had canning and bagging supplies, you could be able to airtight seal some meats and non-dehydratable fruits and vegetables.

    There's just one teensy problem with this theory.... I've never been in a grocery store with a window. Evan dies of smoked lung.

    • Lore Star

      It should be noted that Stater Bros. Is also my local grocery store, so I went today to confirm this. No windows. I'm pretty sure Matthew Patthew even addressed this in his "Get in and out!" Grocery store theory, but I can't remember for certain.

    • MrSurabane

      I'll do you one better. I've never seen an apocalypse where a lock of any kind would keep out other survivors (or alien overlords), most of whom will have weapons and will take all your food from you.

  • Greensyer

    Well what about the food in the back

  • Timothy Urso
    Timothy Urso

    You can live a lifetime in there and this is the correct answer. Take the soil from the houseplants and create raised bed immediately. Use seeds from vegetables to grow more food. Modify lights from store into grow lights. Compost rotting food to create more soil. Use soil to grow more food and the cycle continues...sustainability! the concept is not that complicated.

    Evan could have taken frozen foods like frozen peas or frozen carrot packages and put them with dairy or meat items to keep them around a bit longer.

  • DaagaVideos

    I think you wont need 2000 calories per day bc you can just not move and sleep the most time possible

    Okay. Now that this glorious theory has been discussed... What would happen to humanity if let's say, all non-insect and non human animals (including marine life above plankton level, even shrimp) in the world died suddenly in one moment, besides humanity of course? I know vegetarian and vegan diets are more than viable done properly, as well as artificial meats ect. But if it happened suddenly, instantly, with our current population acknowledging how essential meat/fish/poultry is to feeding countless populations, as well as having interactions with the insect and flora populations. What would happen to not just us, but the world? Theoretically we could turn the rapidly growing insect populace as a source of sustenance and protein (insects are eaten in many places) but with the demand of their consumption rising so steadily, and our sudden environmental demand for more crop space and agriculture, it's a lot to think about @-@ and if we went a step further to say all animal and insect based life besides humans and plants died off, would we survive? Would most of us die and it just take forever to recover from the starvation? Would our world fall into utter chaos?

    It's me! Your local psychology nerd! Evan is likely to be able to physically survive with the food But if he is all alone for 63 years is likely to go insane in one way or another. And an apocalyptic situation is very likely to be traumatizing and being all alone in a grocery store for decades is not going be helping him. And if he's a person in modern day he is likely to get extremely bored quickly, as people in recent years have better technology which often leads to a more impatient species (for the most part). All those things together, along with the hope that he'll see his beloved Theorista again, he's bound to go insane within a decade at most

    wheat and rice have small eggs from bugs, every time you eat wheat or rice ur eating the eggs. after a few years, the eggs will start to hatch and the bugs will spread through every prepackaged wheat and rice product. (they can also fly) ig it would be edible, but it wouldn't be fun eating expired goldfish (it tastes like paint) with small bugs crawling around it

    So I was right in thinking that obviously if it's a grocery store there's going to be some plants. From you're going to spoil fruits and vegetables, some even have packet of plants in the gardening isle. Of course he could have just plant it, if you're thinking long game.

    1:29 now think of all the workers who have to put it away. I am one of those people, And we do it all before the store opens up again. And the amount of product is nuts. Then think about around crismistmas time or any holiday. So next time you decide you don't want somethin put it back ware you found it. Or we have to Deal with it wall Putin away the product. Thanks

    I love this theory, but you also left out hydroponics. You don’t need soil abs you can make your own nutrients using food waste and vitamins. All you would need it water and you can have a much more varied food source that just mushrooms and potatoes.

    OMG I couldn’t imagine how anyone could calculate the true stock age of a grocery store as from day to day the quantities of each product vary. One day 20% of the items could be completely out of stock the next day 9% but 7% of the other items re down to half or single item left of the shelves.
