Is it possible some of the area it uses protein from is old cells? I'm thinking parts of digestive system, immune system, old cells it scrubs and reclaims some protein from when fasting. Still catabolic but useful catabolic?

It is called autophagy and happens regularly in our body, but in very small amount. Do experiece greater results, you need prolonged fasting (3-5 days)
