My previous reply to you was stupid since I didn't remember the proper word for the process the body uses and there are video's all over the internet. It's NOT autogenesis it's Autophagy that the bodies cells use to recycle themselves to their pure form again, it requires a minimum of 4 to 5 days of fasting so like ketosis it needs to burn off all the usable sugar before the fat burning and cell regeneration is going at full speed. You can use this to kill cancer or lose a lot of weight without all the extra skin aka spare tire skin hanging at your waist like lyposuction or using drugs like meth to lose weight since the body eats the extra skin thus you don't have surgical scars or hanging skin to make you look nasty. Instead your skin tightens by excess being used for raw materials and food by the cells. Literally a built in repair system that everyone has but nobody knows about because if everyone did the medical industry would be unneeded except for physical damage like broken bones or deep cuts for the most part. We'd also be eating a lot less nationally and globally so the major food companies would take a huge hit in profits since demand would be dropped to much less and we could survive often on gardens so we would all have more money from less big bills like heart bypass and shit like that.
