The Science Behind Intermittent Fasting

While a three square meals a day routine is normal for most people, others have sought alternatives touted to be healthier and life prolonging. In particular there is the dieting style referred to as intermittent fasting. It involves periods of low calorie or no calorie consumption with periods of normal calorie intake. But what is the science behind this relatively new popular form of dietary lifestyle?

Improved body response to damage and stress

During periods of fasting, researchers have observed the body to be better at responding to physical stress resulting in less damage. For instance, tumors get starved and inflammation is notably lower. The removal of toxins and damaged cells is also observed to be improved during intermittent fasting. Any damage to the body such as that of a wound is healed at a faster rate.

Gives the body time for rejuvenation and repair

Eating and processing food is a lot of work for the body. A lot of resources are directed to the digestive and nutrients absorption process. But during fasting, the body gets to rest and focus more on rejuvenating itself and repairing any tissue damage. This is why people undertaking this lifestyle tend to have higher energy levels.

Eating times and metabolism

Another scientific principle behind intermittent fasting is that of certain meal times being the best for the body. Research has shown that eating during the day, especially earlier in the day promotes increased metabolism and thus better health. This is thus a benefit enjoyed by those who engage in intermittent fasting consisting of regular eating during the day and restricted or no eating at night.

Human growth hormone (HGH)

Most of the science behind intermittent fasting is driven by increased levels of human growth hormone which occurs during fasting. Better muscle repair, faster tissue healing and higher energy levels are all brought about by higher HGH levels. In addition, this increase in HGH during intermittent fasting has been proven to slow down aging and increase physical endurance.
