Autophagy is how a cell naturally clears away dead or unhealthy cells in your body. You can do that 2 ways and both of those ways require stressing the cell.
Way number 1 – exercise
If you exercise you can stimulate autophagy.
Way number 2 – fast or deplete your body of nutrients
Fasting and caloric restriction has been shown to increase autophagy.
Why you want to do that
Autophagy clears away the dead and unhealthy cells in your body. The older you get the more of these cells you get in your body.
So autophagy promotes health and healing in your body by clearing away dead and unhealthy cells.
If you are not doing these things then you are essentially speeding up your own destruction.
- Reduce inflammation
- Speed healing
