Daily Food and Water Needed to Survive…

by Rob on September 4, 2010 · 11 comments

If all the grocery stores were shut down (or it was unsafe to travel to them) and the water stopped coming out when you turned the faucet (or if it were somehow unhealthy to drink)…

How much food and water would you need to survive?

First you can make it about three days without water, after that figure about 1 gallon a day per person including cooking, cleaning, and minimal personal grooming…

And food is different but on average you need about 2000 calories a day, and likely more if you are very active chopping wood to keep warm or looking for food… but let’s say 2000 calories a day.

So, a person needs 30 gallons of water and about 60,000 calories per month…

Or about 365 gallons and 700,000 calories a year…

For a family of four, figure 1400 gallons of water and 3 million calories to survive a year…

Some of these calories need to be protein and fat, but you will probably be close to 70% carbohydrates… (rice, wheat products, pastas)

We’ll talk another time about things you can store that will last a long time and provide a lot of these requirements…

And, you should also plan on taking a good multivitamin every day…

Get Prepared Beforehand, and Survive whatever comes your way.

It’s amazing we are so dependent on everything functioning as is… I look forward to finding out how to not be so dependent and prepared in the most efficient way possible.

We never stop to think about what might happen if we had no food or water for days. We just seem to take it for granted. Clearly, in the aftermath of several major disasters over the last few years, we should all be developing a plan for having access to the barest of essentials in the event a disaster comes calling on us or our loved ones.

This is all great information. Thank you.

The one thing I have never been good at is storing water. I would love some ideas.

Taking a multivitamin is great advice!

Rob we live in a drive through society and forget that when natural disaters happen we cant always just go to the market and get what we need. A great reminder as to setting up some sort of food storage.

Take a food diary for a week or two you will be amazed at just what you consume knowing how easy and plentiful food is available now re read what Rob is saying and make preparations

This winter I survived two snowfalls, each three feet in depth. Not much to the midwesterners but it brought the DC area to a stop for a week each time. No power and no access to stores can really open your mind.

I think it’s impossible to survive without water but this winter I saw on Tv a yogi who was proven that hasn’t eat any food for the last 73 years. I think it would be a good idea to ask him some secrets! Just in case we run out of everything!

Hi Survival Rob,

30 gallons of water. Hmmm, ok, I’m not going to be able to store that much where I live. However, I can safely stockpile several gallons which should last us at least 3-4 days.

Happy Dating and Relationships,

I went on a few four-day fasts back in England, and I found that going without food was not a big deal, but it’s really tough to go without water – and probably unhealthy too.

When you work out your annual intake, though, the figures do seem really large, especially if you imagein 365 x 1 gallon containers all in front of you at the same time.

I need to step it up. I only have 5 gallons of frozen water in our freezer. Thank you for this powerful reminder on the importance of water and having the proper supply.

Yours In Health!

I expect that food and water will always be easily accessible. Thanks for opening my eyes to the other possibility.
