I know people who do 1 day water fast and 1 day dry (no food OR water) near every week - incredible what the body can do and we were misled about by the mainstream!
hunger is mostly mental cravings; or any bad physical feeling is withdraw and body cleaning.
Hear often that hunger is GONE 2 or 3 days into a fast and won't return for a week or never - I haven't been reguarly hungry (daily) in a year or so
