A fast metabolism is something we all desire. Traditionally, it has been known to be achieved through methods such as HIIT training, consuming specific metabolism-foods (hello chilli), getting a sufficient amount of sleep, and drinking more cold water. But the most effective by far is intermittent fasting.

Although numerous studies have already proven the popular diet is beneficial for losing weight, new research published in the Scientific Reports revealed its benefits go way beyond the general ‘weight loss’ aspect of a fast metabolism – in fact, it’s also a good way to promote long-term health and longevity.

A group of scientists from the Okinawa Institute of Science and Technology Graduate University and Kyoto University identified a series of metabolic markers that normally decrease with age. They discovered that fasting increases these markers, which has the potential to protect our health in a myriad of ways.

The specifics of the study do get quite complex, but in layman’s terms, when we deprive ourselves of food for a certain period of time, metabolites like butyrates – which had anti-inflammatory properties – are released. This also occurs for chemicals like purine and pyrimidine, which are crucial for gene expression and protein synthesis (molecules that prevent age-related diseases and decline).

“These are very important metabolites for maintenance of muscle and antioxidant activity, respectively,” said the study’s lead author Dr Takayuki. “This result suggests the possibility of a rejuvenating effect by fasting, which was not known until now.”

The new research proves that intermittent fasting is not only beneficial for helping with weight loss and maintaining healthy muscles, but it also positively affects the more intricate metabolic processes that occur within the body – especially the ones that promote long-term health and longevity.
