Benefits of fasting

Strengthens the immune system

Fasting strengthens the immune system. Valter Longo, Director of the Longevity Institute of the University of Southern California, who wanted to analyze it scientifically proved it the effects of 4 days of assisted fasting on the immune system of a group of volunteers. As Dr. Longo underlined thanks to this practice: "the immune system gets rid of useless, unnecessary cells, while it is pushed to put into action in a natural way, as it happened in the moments of birth and growth, the stem cells capable of ensure regeneration ".

Fights inflammation

To confirm the benefits of fasting against inflammation are the American researchers of the Yale School of Medicine who in a study showed how, during the break from food, our body produces a substance capable of extinguishing chronic inflammation. This is β-hydroxybutyrate (BHB) capable of inhibiting NLRP3 which in turn is part of a complex set of proteins that guide the inflammatory response in many pathologies, including several autoimmune diseases. A good result that suggests that therapeutic fasting can be used in the early treatment of many inflammatory diseases in the future.


Extends life and prevents disease

Always Valter Longo has recently perfected his studies on fasting, actually on a fasting-mimicking diet for therapeutic purposes. This therapy does not propose a complete fast but a diet that provides for a certain restriction of food intake. Those who follow this diet do it in agreement with an expert for 5 days a month. The fasting-mimicking diet not only makes you lose weight but slows down the aging process that shorten the life e helps prevent disease cardiovascular, diabetes, obesity and cancer.


The body not engaged in the digestion of food can better dedicate itself to its purification by removing toxins through its excretory organs. These great internal cleaning obviously have positive repercussions on the health of organs and tissues.

Among other things, among the effects of fasting confirmed in this case there is also that of protecting lean muscle mass and metabolic balance.

Makes you lose weight

A day or two of fasting can help the body lose weight but as always it is important to emphasize that the best way to lose weight remains to follow a balanced and healthy diet in which portions are limited a little if necessary (under the advice of an expert) and keep one correct lifestyle that includes regular physical activity.

Helps the formation of new neurons

A 24 hour fast also helps the brain in the formation of new neurons and is therefore a natural ally of the brain. In fact, it seems that lucidity and memory also benefit from a short fast.

Strengthen the spirit

Just drinking unsweetened water or herbal tea for a day or two may not be a very simple undertaking, not so much for the body as for the mind. Among the positive effects of fasting, when it is successful, there is also that of strengthening the mind and willpower.
