I need a quick answer: just how long did the energy from your last meal last? One hour, two hours? How long did it take until you got hungry just as before? The replies to these questions have got much to do with the macronutrient content of what that meal included. And you had better believe this has severe implications for the optimum survival foods for a disaster situation.
Forms of calories and energy
We all know, all calories were not created equal. Looking over any nutrition label, you are likely to see calories at the very top. Everything beneath can be classified into calories from one of three major sources, protein, carbohydrates, and fat. The calories from these three groups will always sum up to the entire amount of calories in a meal since they are the units of energy which will make up a food. All pathways result in the same end location: usable energy for your body.
Fat metabolism (ketones)
Earlier in human record, our ancestors and forefathers used to roam the lands following herds: buffalo, gazelle as well as mammoth. We were hunters, so we supplemented this diet with natural herbs and the roots of plants we could find. The meat we would eat from these animals comprised a lot of proteins, however, most of the usable calories came from fat, which is considerably denser in energy. Fat is converted into molecules named ketones in the blood stream that are used by cells as energy. This energy offers a maintained burn for constant energy; being in a state of using fat as energy is named ketosis. Whenever we had a large kill, or if we found fresh fruit to reap, our bodies could store these extra calories as fat.
Carbohydrate based metabolic process (sugar, starch and glucose)
In primitive periods, carbohydrates were scarce. Before civilization, whole grains were not cultivated or processed in an organized way. Crops were not grown as we were nomads. Carbs were available extremely rarely and would have to be stored as fat for the lean periods in advance if they were found. Carbohydrates break apart quickly in a sugar known as glucose which is carried in the blood, boosting blood sugar levels. The hormone insulin works as an essential within the gateways of the body cells allowing glucose to get in.
The issue with the modern diet plan
The issue is, fat as well as carbohydrate metabolism are mutually unique. Carbs, being unusual for millions of years of history, are preferentially used by our bodies. As modern people, we live in a state of constant harvest. The body respond to carbohydrates with the objective to store, insulin is released to shuttle them into our cells.
When you view the standard American diet, every meal has carbohydrates. From the bagel at breakfast time, to the sandwich at lunch time, to the steak and potatoes for dinner, we continuously consume carbohydrates. This makes us less able to utilize fat as a fuel source. Transforming into ketosis takes more than a week for lots of people, and until then the fat on the body can't be used for fuel.
If you turn off the faucet for carbs, you will have big problems from an energy perspective. How will you avoid this, and how will you prepare yourself from being segregated from food? More in the next article in this series.
