The Benefits of Intermittent Fasting
By Dr. Mercola
It’s long been known that calorie restriction can increase the lifespan of certain animals. More recent studies suggest that intermittent fasting can provide the same health benefits as constant calorie restriction, which may be helpful for those who cannot successfully reduce their everyday calorie intake. “Undernutrition without malnutrition” is the only experimental approach that consistently improves survival in animals with cancer, and extends overall lifespan by about 30 percent.
Both intermittent fasting and continuous calorie restriction have been shown to produce weight loss and improve metabolic disease risk markers. However, intermittent fasting tends to be slightly more effective for reversing insulin resistance. Besides turning you into an efficient fat burner, intermittent fasting can boost your human growth hormone production (aka HGH, the “fitness hormone”) by as much as 1,200 percent for women and 2,000 percent for men.
Intermittent fasting can also improve your brain function by boosting your production of a protein called brain-derived neurotrophic factor (BDNF), which protects your brain from the changes associated with Alzheimer’s and Parkinson’s disease, and helps prevent neuromuscular degradation.
