The human body is capable of surviving without food for quite a long time.
This is due to evolutionary adaptation developed over thousands of years.
Scientists have conducted a study aimed at studying the changes in the human body if you completely exclude food intake for seven days, reports the journal Nature Metabolism .
Fasting is often used to lose weight. However, the exact mechanisms that occur in the body during fasting are still not fully understood.
An international group of researchers, in an experiment on volunteers, discovered that during fasting, the body switches to absorbing calories from its own fat reserves instead of glucose.
At the same time, the volunteers' bodies show distinct changes in protein levels. This is how the body begins to respond to stress.
It is noteworthy that fasting promoted significant modifications of a brain-specific protein.
Scientists claim that fasting done correctly is actually beneficial. Positive effects are achieved after just three days of restricting any calories from entering the body.
Previously, scientists discovered what prevents the immune system from fighting tumors.
