there is no data on this as yet. how long you fast (once a month three times a week) is an issue. as well what kind of fast are we talking about? scientists have been studying severe caloric restriction for years in animals. you might say they are kept in a state of semi-starvation. indeed these animals do have a lower incidence of some medical conditions but at what price? no one can ask the animals if they’re enjoying any of this. on the other hand keeping total calories under control with a healthy lifestyle that includes physical activity is a reasonable way to rein in calories and achieve an optimal life span.
can fasting help prolong your lifespan?
