Start your breakfast with high-quality protein powder and insoluble dietary fibers (about 20-30 grams each; you can mix them together in a cup of cold water). There is fairly clear evidence that fiber and protein can increase satiety and reduce cravings thoroughout the day. Sure, it's not "natural", but it beats making implausible resolutions to organize your life around low-calorie, fiber-rich meals - especially if you don't like veggies or don't usually cook your food.
Starting a food storage plan with canned goods is a great way to bring non-preppers, family or friends, on board. This tactic allows for families that normally would not have extra food to easily add food to their pantry in a way that is very normal to them. Buying a few additional canned goods while you are at the grocery store is a simple first step, and one that could pay off big time. (Do you know how to open a can even if you don’t have a can opener?)
If you live in a hot and humid environment, you have to store the food a little differently. I live in Florida, and I recommend sealing 1 lbs to 5 lbs in mylar bags and storing those in sealed 5 gallon buckets. It creates a double barrier and smaller bag sizes if you have to open them in an emergency. It might seem more expensive, but it is better than losing everything to water or humidity. It also makes great barter material in a shtf situation.
Still, as I sat at my desk one afternoon, eyeing the colorful salads my coworkers were having for lunch, I realized the absurdity of my experiment: I live in a city with 24/7 access to fresh food and work a job that affords me the privilege of eating healthfully most of the time. Even quibbling over the nutritional content of these freeze-dried meals was something of a luxury, because I wasn’t in a position where I actually needed to eat them. Then again, you never know what’s going to happen.
