(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.
