Can i jist sleep the whole day to help fasting?

I want to attempt a 3 day fast to get rid of old cells and regenerate new ones. However i know that if im working and not even training ill be hungry, when I sleep in or lie in or nap I seem to get over these urges. If I was to have 3 days off holiday. Fast for those 3 days but largely slept in would that still work/ help? via /r/intermittentfasting https://ift.tt/86JbyWS https://ift.tt/RgrdMSV
