Diet is the behavior that’s been studied the most in terms of trying to affect thing like aging and longevity.
There really three components of diet that seem to be impacting aging :
So the first is. How much we eat , the second is what we eat , and the third is when we eat .
So in terms of how much we eat , a lot of science went into this idea of caloric restriction . Caloric restriction isn’t a starvation .it’s usually just about a 20 precent reduction in the overall caloric intake . The other thing , that has been study , is this concept of what we eat , a lot of research has gone into whether things like plant-based diet are actually beneficial to aging and longevity, there seems to be some evidence ,that eating less animal products , more fruit ,veggies , more wholefoods ,it’s going to be better overall .
But what scientists found , is actually fasting can (con mimic ) some of the benefits , that we’ve seen with (caloric restriction ) , so if people can perhaps minimize their eating to a small window , we think (that this can actually recapitulate ) a lot of benefits , that we are saying in the caloric restriction studies .
