Fast, living for some time without food or with limited amount of food has a long belief in almost every great religion on earth. Not so long ago people fast even if they don't desire to. They produced food for themselves, but sometimes, for example at early spring, they had to wait for crops. They had to fast. But how fasting effects health? And how fasting effects brain health?

When animal fast, it lives much longer in compare to an animal of the same species, which takes as much food, as it desire. Rats with short food for example live even 50% longer. Some closely related to us monkeys, rhesus, live much longer too, only if they are in need of food for most of their lives (Kostevski, 2012).

There is a long-lived group of persons in Japanese island, Okinawa. The oldest and most healthy of them still have in mind the second world war, and long time of no food. They not overeating even now. One of their customs is to take only 80% food they need and never eat to your heart's content (Buettner, 2015). First works in science confirm that limited food may make better our health, what Okinawa's people have known for hundreds of years.

Any kind of fast may lower the chance of diseases like cancer, diabetes or overweight (Barnosky eat al., 2014). You may fast every second day – limit your normal amount of food by 50% one day, and eat whatever you desire second day. You may fast only when your religion requests it. But keep in mind that when you fast, you have to take a high quality food, to keep yourself from vitamin deficiency. In short: put somewhat plants protein before animals' one, take your greens (Levine at al., 2014). Be careful with fasting, it may cause damage to your body. But if you use it with care, it may make not only your health but in addition your mind better. Some proofs show the brain feels better after fast and memory may boot up (Witte et al., 2009). If have any doubts, put a question to your doctor.
