Biological facts about fasting




Fasting is the refraining from eating and drinking from 8 to 12 hours. It has religious and spiritual meanings in different cultures. However, some people practice it for health reasons, mostly, for losing weight and delaying aging.

Also, it increases numbers of red blood cells, white blood cells, which fights diseases and inflammations, and platelets. Removing toxins and lowering fats from the body are other benefits for your immune system. Free radicals, which are waste products from various chemical reactions, including metabolism. Although these substances can damage the cell’s DNA and case series disease, for example cancer, many of them are essential for life. They can be found in food and medicine. Thus, fasting can reduce the occurrence of free radicals.




  • Delays aging

Muscle loss due to aging, or sarcopenia, is associated with low metabolism. In order to increase your metabolism, fasting is one option, helps in the degradation of muscle tissues. Cells are dividing and growing every 24 hours; however, aging makes the cells older and lower their performances. Autophagy, is a natural, regulated mechanism degrades and recycles cellular components; fasting activates this process, leading to delayed aging. Also, it increases immunity and activates anti-aging hormones, meaning less wrinkles and more youthfulness. Drinking plenty of water because of the dryness keeps the skin and the body moisturized, secreting collagen and elastin.


  • Boosts metabolism

Leptin, is a hormone that regulates energy balance by inhibiting hunger. A decreased sensitivity to this hormone results in inability to detect satiety. Whereas, improved leptin sensitivity increases the rate of your metabolism. Fasting reprograms liver proteins; the liver’s enzymes are prompted to break cholesterol and fats, converting them into bile acid, which in turn is converted to heat, stimulating faster metabolism.

Fasting lows one’s appetite, encouraging him to follow healthy diet especially water and fruits diet. The long hours refraining from eating, help controlling bad habits and regulate the right sense of hunger by sending correct messages to start eating. Additional result is helping addicted patients, such as food addicted and caffeine addicted.


  • Improves brain function

Fasting increases the production of brain-derived neurotrophic factor, or BDNF, which is a vital protein, active in the vital areas to memory and higher thinking. Release of BDNF activates stem cells within the brain and converts them into neurons. Stem cells can self-renew and differentiate into any cell types in the body, from heart cells to brain cells to muscle cells. Increased production of BDNF protects the brain cells from the degenerative changes that are associated with conditions, such as Parkinson’s disease and Alzheimer’s, while low levels of BDNF associated with depression and several other brain problems.



Unfortunately, some cases had to consult the doctor before starts fasting, for example, pregnancy, breast-feeding, or gastric ulcer. Stay safe.

The main reason behind inventing the soap was cleaning dishes and using it in medicine, as Galen mentioned. Babylonians around 2800 BC were the first, who manufactured soap-like materials, using plants and animal fats boiled with ashes and water.  Whereas, the ancient Egyptians in 1550 BC made a product similar to soap through mixing animal and vegetable oils with alkaline salts, and women used it for washing their hairs.
