Three square meals a day used to be the definition of healthy eating. But no more. New research shows that skipping meals here and there turns on longevity genes and can lead to a longer and healthier life.
Studies in animals have shown that drastically restricting calories or fasting extends lifespan and improves age-related diseases. But it wasn’t clear whether people could achieve the same results.
After all, fasting on a long-term basis or restricting calories over a period of years would be a difficult lifestyle for most people to maintain. (more…)
Scientific research is finally validating the ancient health and healing practice of fasting. The Telegraph recently reported that scientists at the University of Southern California (USC) have discovered that fasting “for as little as three days can regenerate the entire immune system,
even in the elderly, scientists have found in a breakthrough described as ‘remarkable.'”
Researchers suggest that the mechanism behind this phenomenon is that “starving the body kick-starts stem cells into producing new white blood cells, which fight off infection.” And fasting “‘flips a regenerative switch’ which prompts stem cells to create brand new white blood cells, essentially regenerating the entire immune system.” (more…)
The health benefits of fasting should be taught to every oncologist in the world. You can actually kill cancer cells with many different types of fasting techniques. Obviously, cancer patients should work closely with a trusted, qualified healthcare professional before attempting a fast of any kind.
Although not widely-known, studies have found that fasting slowed the growth and spread of tumors and even eliminated the threat of cancer in some patients.
How does fasting help cancer patients? (more…)

Fibroblast growth factor-21 (FGF21) is a hormone secreted by the liver during fasting that elicits diverse aspects of the adaptive starvation response. Among its effects, FGF21 induces hepatic fatty acid oxidation and ketogenesis, increases insulin sensitivity, blocks somatic growth and causes bone loss. Here we show that transgenic overexpression of FGF21 markedly extends lifespan in mice without reducing food intake or affecting markers of NAD+ metabolism or AMP kinase and mTOR signaling. Transcriptomic analysis suggests that FGF21 acts primarily by blunting the growth hormone/insulin-like growth factor-1 signaling pathway in liver. These findings raise the possibility that FGF21 can be used to extend lifespan in other species.DOI:http://dx.doi.org/10.7554/eLife.00065.001.
Despite the luxuries of the modern world and the perceived abundance of food, the human body is much the same as it was 10,000 generations ago. During that time, known as the Paleolithic Period, humans did not have welfare, food stamps or discount grocers. As a result, men and women did not eat nearly as regularly as we do now, and on average about one day per week they would go without any food at all. Obesity was unheard of as anyone who managed to become overweight was quickly devoured by wild predators due to their sluggishness. During this period (which covers Pliocene and the Pleistocene epochs) our bodies developed powerful detoxification methods that were triggered by the rhythm of food consumption of the era. Nearly 99% of human existence so far was during this period. The last two centuries of the Industrial Revolution are a mere instant compared to our entire history on Earth, which is not nearly enough time to evolve or even adjust to our modern diets of processed food.

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. (more…)
Fasting has been a popular practice among health conscious individuals for centuries. In general, doctors have discouraged the practice of fasting deeming it a dangerous fad among ignorant health seekers. Recent research has proven that regular fasting is not merely a fad, but a health promoting practice. Research conducted at Intermountain Medical Center’s Heart Institute identified several health benefits offered through periodic fasting.
One of three North Americans will become diabetic because
they eat a high-calorie, high-fat diet that *blocks insulin
receptors *to prevent cells from responding to insulin (insulin
resistance) *to cause high insulin levels *that constrict coronary
arteries *to cause heart attacks. Failure to respond to insulin
causes *high blood sugar levels *that cause sugar to stick to cell
membranes *to permanently damage the affected cell *to cause
