Could This Simple Restriction Be An Ancient Secret To Longevity?
"Humans live on one-quarter of what they eat; on the other three-quarters lives their doctor."
Egyptian pyramid inscription, 3,800 B.C.
Here is the secret to longevity and health backed up by research that the pharmaceutical companies and food industries don't want you to know; the secret is out: it is fasting. Through different methods of fasting we can delay the onset of aging and disease. Studies on mammals have shown an increase life span up to 30-40%. Fasting has effects similar to calorie restriction, which its self has been shown to increase longevity in humans, though it can in the opinion of some be harder to implement due to the psychological constraints of constant restriction. Fasting does improves cholesterol levels and also has been shown to delay the onset of heart disease. Fasting in a sense takes the body and puts it into a repair-like state and raises the level of human growth hormone, thus keeping the body in a youthful state.
People also have been shown to eat less food after a fast due to the shrinking of the stomach; for example, on the alternate day fast, the feast day of the fast, we no longer have the space to make up for lost calories; so while it's expected that someone would eat up to 175% of their normal intake, they actually only end up eating 110%, which at the end of the week really doesn't add up to much. This life style of alternating one day of eating and one day of fasting finds its validity amongst scientists because it seems to make some evolutionary sense. The idea is that nature built the human body in such a way that it could survive and thrive through periods of drought and famine. Consider this: during the great depression life expectancy rose by seven years in the United State; it seems kind of counter intuitive, but its true.
Fasting is a great way to keep the body lean and strong, especially for anybody struggling with their weight that has not been able to find an answer, though has tried many things. It could be that their body is very efficient at surviving a famine, and with the stress of our daily lives, believe it or not, that can also put the body into a state of feeling like it is in a famine. A lot of people find it easier to lose weight this way because they know the next day they can eat what they want, that is, within reason of course. With any diet it is very important to get all your fruits and vegetables and to stay hydrated on days when fasting. This diet also shows that everything is okay in moderation. On fasting days some people eat a small meal under 500 calories while others go with out; the only other thing to have on fasting days is zero-calorie beverages, like tea and black coffee. Starting out you may be hungry; that's perfectly normal; over time your body with adapt. If you look around the internet you can find people that have lived this life style for over 5 years that are very happy, healthy, and rarely get sick. The reason they are healthy is because their body does not have to fight of the same amount of free radicals taken in with their food. Another thing you will find is that the days you are fasting you are super productive.
Fasting is great for reducing inflammation and oxidative stress throughout the body. When the body is in a fast another interesting thing that happens is that the body stops burning sugar and starts burn fat for fuel, which is what causes the weight-loss; after about 8 hours of fasting your glycogen stores are depleted and it starts to burn the fat you have stored up for this occasion; an effect similar to high intensity exercise, this is called a shift in energy metabolism. Worth stating is that because fasting has its own psychological challenge it has been shown to activate something called an adaptive stress response pathways to over come famine. In doing this you end up with better cognitive performance as well as more activity in the nerve circuits; probably due to the idea that the body knows it needs to find food and has to be creative. Fasting has also shown to promote the growth of new neurons and strengthen the synapses. These effects have been compared to exercising because the mitochondria in the muscles are increased; in fasting the the mitochondria are also increased but not in the muscles, in the brain. Fasting also creates an atmosphere in the body where nerve cells are better able to repair DNA.
While fasting it is very important to stay hydrated and drink anywhere from one half a gallon of water to a gallon. When feasting it is important to eat nutrient dense foods; there are tons of tools out their on the internet to assist you and educate you in that matter.
