You'll need more food and water than you think.

You'll need more food and water than you think.
I've culled this article from the Rawles site because IMHO, its an important article. The take away for me is that we will need more water and more calories per day than we thought.

If we think in terms of 1200 calories which is kind of standard in freeze dried packs and other supermarket foods that are one serving of around 750 calories, it just ain't enough. I think you have got to reckon on 2000-3000 calories per day if you are going to keep active and have any strength.

Survival Is Not Fun, by Wild EMT

Bug-Out!
A friend and I recently discussed some of the possible physical difficulties that might be associated with a rapid exfiltration from a devastated area during a major grid-down scenario. We thought it would be interesting to explore the personal effects of increased stress, combined with decreased caloric intake, which might be encountered while “bugging-out.” We wanted to move away from academic knowledge to personal experience, so we created a seven day bug-out “challenge” for ourselves.

Background note: my survivalist friend was a U.S. Marine who served in Vietnam and then spent his career working on computers. I'm a 46-year-old male who exercises daily by running and lifting weights. I'm also a Wilderness EMT-B and I teach wilderness survival and wild plant skills as serious hobbies. We both grew up in rural Utah, and we’ve spent many years backpacking throughout the Rocky Mountains. We also invited another survivalist buddy (lawyer) to participate in the seven day challenge.

The Challenge

Consume only 1,200 calories daily
Run 5K or bike 10K each day
Work manual labor (or) lift weights one hour each day
Sleep only 6 hours a night on the floor or ground
Refresh your (heavy) bug-out bag and wear it at least 30 minutes a day
Capstone: Run 15K or bike 30K with a (light) pack at the end of the challenge

We picked 1,200 calories per day because this is the approximate amount of freeze-dried survival rations that we carry in our bug-out bags (and it's also the amount with which we've stocked our families' bug-out bags). The idea was to test these calorie limits while under increased stress. We couldn't simulate everything perfectly, as we still had to work each day and support our families. However, we thought this limited set of experiences would be achievable and educational.

Our friend the lawyer never started the challenge. In addition, my Marine Vet friend shifted to 2,000 calories by the third day after struggling with effects of calorie reduction, although he continued with the physical challenges. I personally stopped the challenge after five days – here’s why:

Body Temperature
By the end of the second day I started getting cold and then I stayed cold. I went from one blanket to two at night. This was odd for me, as I don't get cold very often. My metabolism is fairly high and I was probably feeling the effects of a reduced metabolic rate as my body adjusted to fewer calories. One takeaway is that in a major crisis, I would probably want a larger sleeping bag than the ultra-light one I currently carry. In addition, I'll probably include an extra base layer of lightweight underwear just to maintain body heat when additional food isn't available.

Physical Fatigue
Under these austere conditions, by the third day I was taking nearly twice as long to run my standard 5K route (7,000s-foot elevation, two large hills). For me that was huge, as I run this route regularly. After four days of this grueling exercise regime, I became a little light-headed just climbing a few flights of stairs. The lack of calories really affected my overall physical performance. Occasionally while I ran, I would get a weak out-of-body feeling. I felt feeble in my arms when I did pushups or worked outside with a shovel. I also experienced difficulty sleeping only six hours -- I was a little wired at night, but then I had trouble getting up the next morning. My stomach growled constantly and I even experienced low blood sugar "shakes" in my hands after exercising. I simply didn't have the fuel to perform at normal levels. A key takeaway is that I'll need to factor in a slower pace when backpacking and running long distances, as well as more time to complete light construction and related manual labor during a crisis. I might also need a small, manual-wind alarm clock of some kind.

Lack of Mental Clarity
By the fourth day images of food consumed most of my mental down time. When I wasn't thinking about family or work, I found myself drifting off while wistfully envisioning peanut butter on bread. I love peanut butter, and my brain probably associates that food with calories, so images of peanut butter became my near constant companion. I awoke the morning of day five to a vivid Technicolor dream of eating stacks of pancakes in my grandmother’s kitchen. I also found myself mentally "dull" or not as "quick" when it came to making decisions and/or responding to everyday challenges. The takeaway here is that with a fuzzy head, falling back on training will become important during a crisis. As a Wilderness EMT-B we are drilled to follow standardized patient treatment pathways and protocols for every single medical scenario. This ensures that we hit all the critical steps while under stress. During a collapse, training will probably dictate many of my decisions when I’m too hungry and exhausted to think clearly.

Sickness
By the fourth day I also began to get a sore throat (remember that we were really pushing ourselves physically). My immune system was clearly weakened due to lack of food and sleep. I'm sure that if this exhausting regime continued for another few weeks, sickness would become my constant companion. I responded to the sore throat by sleeping an extra hour, popping lots of vitamin C, and drinking more liquids. This helped, but what if I couldn't add another hour of sleep or if I didn't have a ready supply of vitamin C? I could potentially supplement with wild rose hips, which are plentiful in my area (even during winter). But what if I didn't know what plants to use? Historically, during wars and other periods of extreme deprivation, more deaths occurred from malnutrition and sickness than from direct hostilities. When your immune system is weakened, a simple cold that you dodged during seasons of plenty might become a serious health concern. My takeaway here (besides obviously trying to eat and sleep more when possible) is to throw into my bug-out bag a small bottle of multivitamins and/or vitamin C, as well as dedicating even more study time to what local plants may be helpful (albeit feebly) when sick.

Behavioral Changes
My wife complained that I was grouchy during the challenge. I've learned that care must be taken to control irritability and the tendency to snap at others in your family or team when fatigue sets in from too many sleepless nights and not enough food. Kindness and patience come easily when your stomach is full, your family is happy and healthy, you are fully employed, and your DVR successfully records your favorite television program. But can you practice charity and self-control when everything is collapsing around you and you can't even think clearly?

Weight Loss
After the fourth day I was down nine pounds. This much weight loss in such a short period of time simply wasn't healthy – I pulled the plug on our little experiment at the end of day five. I remember once reading an article on SurvivalBlog.com that suggested being 10 pounds overweight during a system collapse might be advantageous. As a middle-aged exercise junkie I thought "how could being 10 pounds overweight be even remotely beneficial?" Well, I've just learned that under stress and with reduced caloric input, I'll easily burn 10 pounds or more in a week if I'm carrying a heavy pack and dragging my family away from a crisis zone. Of course, the assumption here is that one is in excellent physical shape (regardless of being a few pounds overweight) so they can actually perform under great duress. Over the course of the last year I’ve increased my exercise regime knowing that being in shape may be the difference between living and dying in a collapse scenario.

Cheating
I cheated twice during the experiment. I ate an extra 100 calories of peanut butter on two separate occasions. My body was literally screaming for food and my brain was starting to rebel. Most folks will probably cheat a little bit under similar conditions. But stealing a few extra calories now and then may reduce how long you can survive with your given stash. Because I teach wild plant food skills and I grew up hunting, I'll (theoretically) be able to augment my food storage with a few (very few) additional calories. But knowing that I have a tendency to want more calories than I currently have stashed for myself and my family, my personal takeaway is to add to my total larder (and especially to our bug-out bags) while the stores are still open. My initial estimates of how much food my family will need while bugging out (or “bugging in”) were too low.

Recovery
Coincidentally, I had a doctor’s appointment immediately following the challenge. The nurse asked if I was dehydrated, as she had a very difficult time finding a vein from which to draw blood. My resting heart rate was approximately 64 and my blood pressure was approximately 106 over 71. I thought I had been over-hydrating during the increased exercise. It turns out I hadn’t hydrated adequately. I also gained back about two pounds later that day when I ate as many peanut butter granola bars, peanut butter sandwiches, and glasses of milk as I could hold! I diligently lived up to the exercise component of our challenge, and I learned that I simply wasn’t drinking enough water (and I thought I was pretty good at hydrating). The takeaway here is that in a crisis, forcing yourself to drink more water than you want (or can perhaps even hold on a shrunken stomach) will be critical. Water will always be more important than food in any crisis. I probably need to add an additional water bottle (or two) to my bug-out bag in case finding water becomes difficult.

“Survival Is Not Fun”

This real-world experiment might seem a little strange to most, but I personally learned a great deal about how my mind and body react to stress, increased physical exertion, and the significant lack of calories that will accompany many of the larger collapse scenarios. Your experiences may vary under similar conditions based on your own level of fitness and your personal metabolic rate. The ultimate goal here was to test ourselves, our equipment, and our survival food choices. We achieved that goal, although the experience wasn’t much fun. As Les Stroud of Survivorman fame states: “Survival is not fun. It’s not pretty. It’s never comfortable. It may involve eating gross things, enduring pain and deprivation, and battling fatigue and loneliness.” Prior to this exercise I was quite cavalier about how little food I would need to maintain optimal performance levels under stress (I'm invincible, right?). Now I know from personal experience that I need to eat more calories and drink more water than I previously estimated if I want to stay physically and mentally sharp during the first critical phases of any future collapse.

RE: You'll need more food and water than you think.
I did see an article somewhere that stated that if severe physical output is required you can up the calorific requirements to 5 to 6000. I dont think thats going to be an option. I cant physically store foods like that. What ut mean is as well say you et some bacon post shtf, you eat all the fat as well not just the lean meat. You eat the marrow from bones etc. Ive got ulti vitamins with minerals in my stores, that way at least my body will be getting some of what it needs if times are lean for a while.

Excuse the spellings i posted from my phone!!!!
I tried to be normal once.... Worst two minutes of my life...

RE: You'll need more food and water than you think.
Well, if you know that 1200 calories isn't going to be enough for such a strenuous exercise, it does seem a bit pointless to do it just for the sake of finding out if you can. The most strenuous armed forces exercises (probably those in Norway and cold climates) provide dried food which are far, far in excess of 1200 calories, and those guys really know what they are doing. Does it seem likely that in a SHTF scenario you will be lifting weights, biking 10k and doing all sorts of other dodgy things? I suspect most people will be tucked into their homes or bug outs and conserving energy.
I don’t want to hear my neighbour but I want to see the smoke of their chimney.

RE: You'll need more food and water than you think.
I can undertand why they did it but it does seem pointless.

If you are working you need more fuel than if you are sitting about. Fact.

My stores are based around us sitting around for most of the day until we can get out. Then there is a jump in calorific intake to compensate for the extra work. That extra work is creating the next lot of calories.

Even so, it isn't going to be easy. We are not used to going hungry.

most people do not know what the word hungry means....they use it to mean they are peckish.

anybody see the documentarie on eating insects their were these boys about 15yrs old who looked about nine ,you can get away with less food but their is a long term cost .
these asain types need to eat more chips and deep fried chicken Smile Big Grin Tongue

RE: You'll need more food and water than you think.
In the British military the ration packs have 4000 calories iirc because it had to contain enough energy for all activities and as no-one ever ate everything it meant that generally you got 3000 calories per day.

So for SHTF you could cope on less really in my case cos of bugging in but post SHTF when farming and rebuilding you would need the full calories intake.

And that is when they will not be as much about or easy to access like now, hence why I agree with people estimating 15 months of food stored as a minimum - but that will take me personally some time to acquire but little and often seems to be working!

Hmmm now just to either remortgage or win the lottery to accelerate the preps!

RE: You'll need more food and water than you think.
They say 2500 average for a man and 2000 for a woman but that is working and actually doing things. Not sitting on the couch all day.

The issue with budgetting is that no one really has their packs split into 1000 calorie chunks. We will open the tins we need and use them. if we get away with less because it is hot and we are laying around all day then fine if we need more then so be it.

I look at the meals we eat now and see the waste. We either just finish it off, my sin, feed it to the chickens or the compost heap. We will learn not to generate any waste but eat enough to be healthy.

No point starving when you have lots of food because you have a plan.

yeah 1200 a day is not that much ,the British army rat packs have 3 to 4000 in 24 hour pack
just read alas Babylon ,so im going to get more salt!!!!

RE: You'll need more food and water than you think.
Remember that although an Army ration pack is 4000 cals, and the average squadie will eat around 3000 cals per day, that is the cals required per day for that exercise [ anything from a couple of days to about 3 weeks ]

If you were living permanently of less cals, your body would get used to that amount, providing it was not something stupidly low

If you consider how armies have fought month long campaigns on almost nothing, say for instance the German Army fighting in Russian cities,.. they fought for months on very meager rations,............... the body can get used to a great deal, and still function very well.

The biggest problem we would have where rationing is concerned is going to be getting used to a less cal diet, we are all used to eating to excess, far more than we need to, going down to only eating what our bodies need is going to be a shock for most of us
A major part of survival is invisibility.
