As a person ages, autophagy decreases, which can lead to a build-up of cellular junk parts and, in turn, cells that arent functioning at their best. During this process, aged and damaged organelles are recycled, providing energy for the cell and cleaning them of cellular debris. Research has linked autophagy with several health effects, but this cellular process is complex, so it can be challenging to draw conclusions. "When you strain the system in a good way, like with fasting, suddenly the cell senses that it doesn't have a ton of nutrients and that it shouldn't be wasting what it does have.".
