What the Science Says About Intermittent Fasting

Story at-a-glance


  • It’s long been known that calorie restriction can increase the lifespan of certain animals. More recent research suggests 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 reducing insulin resistance
  • Besides turning you into an efficient fat burner, intermittent fasting can also boost your level of human growth hormone (aka the “fitness hormone”) production by as much as 1,200 percent for women and 2,000 percent for men
  • Intermittent fasting can improve brain function by boosting production of the protein BDNF, which activates brain stem cells to convert into new neurons and triggers other chemicals that promote neural health. This protein also protects your brain cells from changes associated with Alzheimer’s and Parkinson’s disease, and helps protect your neuro-muscular system from degradation


No human being has ever filled a container worse than his own stomach. The son of Adam needs no more than a few morsels of food to keep up his strength, doing so he should consider that a third of his stomach is for food, a third for drink and a third for breathing’– Ibn Maja

  1. An article claiming scientific facts must be accompanied by references. Otherwise it is completely questionable. Even more care should be taken when Islamic teachings or beliefs are being claimed to be supported by science

  2. Apologies for the previous comment. The link saying ‘more’ was not visible (or I missed it) when I first saw the article. Yes indeed you have a link to a site where someone is attempting to scientifically justify the claims made here.

  3. It’s interesting to note that Japanese people consume less food than the average person. Japan is the country that has the highest life expectancy in the world. It’s also noteworthy that Walter Breuning (one of longest living men who died this century) used to practice fasting and ate less.
