(NaturalNews) Our ancient ancestors grew up in a world of stress and scarcity. Food was often not available and intermittent fasting was common. This form of life left a genetic blueprint with key information pertaining to our health and wellbeing. Intermittent fasting reduces oxidative stress, enhances cellular repair processes and appears to be a key strategy for anti-aging and longevity.
Thousands of years of food scarcity led our bodies to develop a protective mechanism to adapt to alternating phases of food abundance and scarcity. During times of food scarcity, our cell membranes become more sensitive to insulin. This is especially important when food is scarce because it ensures that every bit of food be efficiently used or stored.
During times of food abundance the body desensitizes the cells to insulin in an effort to avoid the stress of a heavy calorie intake. This results in elevated insulin levels, increased fat storage and increased oxidative stress and inflammatory conditions in the body. Insulin also enhances cellular division, which is a risk factor for cancer formation.
Today, we have a massive abundance of food sources. We can virtually eat anytime we would like. In fact, many health coaches recommend eating 5-6 small meals throughout the day. This process, however, sends the body the signal of surplus that inhibits key tissue repair hormones, which have powerful anti-aging effects.
Turning on Genetic Repair Mechanisms
Intermittent fasting acts to turn on certain genetic repair mechanisms that enhance cellular rejuvenation. This adaptation appears to allow certain cells to have a longer lifespan during times of famine. It is energetically less expensive to repair a cell than it is to divide and create new cells. This has a positive effect at shutting down cancer cell formation and proliferation.
These genetic repair mechanisms are turned on through the release of human growth hormone (HGH). HGH is known to create physiological changes in metabolism to favor fat burning and protein sparing. The proteins and amino acids are utilized to repair tissue collagen which improves the functionality and strength of muscles, tendons, ligaments, and bones. HGH also improves skin function, reduces wrinkles & heals cuts and burns faster.
HGH and insulin are opposites in function. HGH is focused on tissue repair, efficient fuel usage and anti-inflammatory immune activity. Insulin is designed for energy storage, cellular division and pro-inflammatory immune activity. Insulin is the dominant player in this game. When conditions demand an insulin release (carbohydrate intake), HGH is inhibited.
Fasting is a Powerful Healing Modality
Intermittent fasting is one of the most powerful modalities for reducing inflammation, boosting immunity and enhancing tissue healing. This is one of the reasons why many people feel nauseated when they have infections. This innate mechanism is the body’s way of influencing us to fast so it can produce the right environment to boost natural immunity.
Researchers at the Intermountain Medical Center Heart Institute found that men, who had fasted for 24 hours, had a 2000% increase in circulating HGH. Women who were tested had a 1300% increase in HGH. The researchers found that the fasting individuals had significantly reduced their triglycerides, boosted their HDL cholesterol and stabilized their blood sugar.
The best way to begin fasting is by giving your body 12 hours between dinner and breakfast every single day. This allows 4 hours to complete digestion and 8 hours for the liver to complete its detoxification cycle. After this is a standard part of lifestyle, try taking one day a week and extending the fast to 16-18 hours. Eventually, you may choose to do a full 24 hour fast each week.

(NaturalNews) The human body was designed very efficiently for times of scarcity and stress. Food scarcity was a common reality and the body has developed specific pathways to be very efficient in times of fasting. In times of stress, for survival purposes we adapted a fight or flight mode that forces us to work our bodies at a very high-intensity for a relatively short period of time. The combination of intermittent fasting and high intensity exercise promotes hormones that improve tissue healing and metabolic processes.
Our long-ago ancestors had to struggle daily for adequate food sources. They most often grazed on wild berries, herbs, raw nuts and seeds as they foraged through the woods during the day. At night, they would relax with the latest kill eating most-often a high protein, high fat meal. This sort of diet was dependent upon the success of their hunting endeavors. Fasting was a regular way of life for our ancestors. This is evident with the positive adaptations the body goes through during the fasting periods.
Fasting allows our body to go into a catabolic (tissue breakdown) period without promoting inflammatory conditions. This enables the bodily resources to eliminate older, damaged cells and replace them with stronger cellular components.
High intensity movement is a way of life
High intensity exercise was a necessity of life for our ancestors as they chased down and killed animals for food. Many cultures battled with other cultures regularly. The fight or flight lifestyle was quite evident and it was almost always at 90-100% of maximal intensity. Anything less than this could quite often lead to death or starvation.
This way of life led to a lean and incredibly strong body. Most men had body fat under 10% while women typically ranged between 10-20%. They were also able to produce incredible muscular forces to overcome obstacles with their battle-trained bodies.
To have high-quality of life in the 21st century, we must understand and work in harmony with our bodies’ primitive past. Intermittent fasting and high-intensity, short durational exercise are genetic requirements that help our bodies thrive, adapt and evolve with better survival characteristics. This includes a strong fit muscular system, a titanium immune system and an efficient digestive tract.
Fasting and fitness boost human growth hormone
Intermittent fasting for periods ranging from 12-24 hours along with high intensity exercise has a positive effect on boosting human growth hormone (HGH). HGH is a very important protein-based hormone that is produced by the pituitary gland. HGH enhances the cellular repair processes that allow us to age with grace. HGH regulates metabolism to burn fat, build muscle, and slow down the negative effects of stress.
Researchers at the Intermountain Medical Center Heart Institute found that men who had fasted for 24 hours had a 2000% increase in circulating HGH. Women who were tested had a 1300% increase in HGH.
A 2009 study in the British Journal of Sports Medicine showed that lactic acid accumulation helps to trigger HGH. Lactic acid is only produced in response to intense anaerobic training. Aerobic training is not intense enough to produce the kind of lactate triggering of HGH.
Low-intensity, long duration aerobic training is catabolic in nature. This means that it produces lots of free radicals without promoting significant amounts of repair peptides, enzymes and hormones. The net effect is a wearing down of bodily resources.
High-intensity training also produces free radicals but it triggers an abundance of repair peptides, enzymes and hormones to be released. The net effect of this is healthy tissue repair and favorable effects on body composition and anti-aging qualities.
