There was a time when 2 boxes of instant rice, 4 pounds of popcorn, a flat of cream of mushroom soup, a flat of pork-n-beans and a flat of raman noodles was all I had in the pantry. I had just changed jobs with a 60% reduction in pay and I was trying to survive with a $12 a week food budget... After 6 months I was eating the raman noodles and saving half the broth mix for my lunch..... I was using people power to go 2 miles to work and back and I didn't have a weight problem...
See there is a good thing about going hungry.
When I first got married we didn't have much extra, and when I went back to school it was tough. My DW is an excellent cook and we lived on beans and rice for 4 years, but we still managed to make BOBs (bug out bags) with 3 days worth of meals for each member of the family. We rotated those every 3 months. For decades we shopped sales and added slowly to our food storage. We monitored our menu and then used that to get an extra months supply in. We kept monitoring our diet and discovered we increased our meat so we added that and a couple more months worth of food, we even tried to include snacks. But our oldest "rat" discovered a box labeled "treats" and when we went for them all we had was a box of empty wrappers.... Eventually we got up to a year's supply and then it became an issue to make sure none of the food went bad, so we developed our First In First Out inventory control, we date everything when it comes home from the store or when we can or freeze something. We have found that using a seal-a-meal will allow us to keep frozen meats for up to a maximum of 4 years (bottom of deep freezer, oops) and as long as the seal was good and no Ice formed inside the bag it was fine. We try not to keep anything in our inventory longer than 2 years.
20 years ago, I had an LDS friend visiting and he followed me into my food storage area (1/4 of the basement) and he said, "If things ever get bad, I'm bringing my family over here..." That was the last time anyone outside the family has been in my basement. I believe in having enough food storage to carry my family through a major SHTF event and sufficient precious metals (Iron, Brass, and Lead) to keep it....
I think of food storage kind of like the old joke about Noah and the Flood and "how long can you tread water". When the floods came I didn't hear about Noah handing out life preservers and rubber rafts, nope he just gathered up his kin & livestock, pulled up the ramp, and closed the doors.
Now don't get me wrong, I have tried to help teach people how to do food storage and emergency preparedness. The wife and I were even asked to teach classes at workshops and even a few LDS sponsored regional events. The wife taught basic cooking (beans, rice, and such) and I taught organization skills, planning, situational awareness, along with food storage methods. We shared what we had taken decades to learn and at the end of the day people just wanted to eat our samples and talk about why they hadn't done anything since the last time we saw them. People want to be prepared and have food storage. But, it is hard to make the sacrifices necessary to be prepared and it takes work. No one can do someone else's food storage for them. As the old saying goes you can lead a horse to water but you can't make him drink. So after a decade of doing the classes 2 or 3 times a year, we decided that the time spent teaching could be better used getting our own house in order.
