Have you ever heard of autophagy? This lemma comes from the Greek and means “to eat oneself”. Although the concept may make you think of something nefarious, know that it is not anything dangerous in and of itself.
Fasting is the most effective method to activate autophagy, the natural process that our body uses to regenerate and maintain health. But let's go into more detail.

What is autophagy?
Autophagy is a mechanism by which cells they cannibalize its damaged or no longer useful parts for get new energy from it. All this allows the body:
- di eliminate waste;
- to promote the cell regeneration.
Autophagy is not activated randomly, but under specific conditions, such as during a lack of nutrients. And this is where the intermittent fasting.
