How much food does a human being really need?
This question I saw being asked in connection with how much food Noach had to supply to every animal in the ark. It seems that a hundred arks would not be enough to carry all the food
.

This week the Tora reading is about Noach and the ark.
From the Talmud it is derived that the consumption of an egg-bulk should be enough to be satisfied [ an egg bulk should be equal to the amount that each animal could swallow at one time—-[Rav Chaim Kanievsky]!

And Rabbi Yehuda [in the Talmud] holds: โ€œAnd you shall eat and be satisfied,โ€ refers to eating that includes satisfaction. And what is considered eating with satisfaction? The consumption of an egg-bulk.
I think that most of us will get nervous if we were told so by a doctorโ€ฆwe got used to eat far beyond this strict necessary.

Berachot 49b how much eating makes satisfaction, say blessings together as a collective on ๐Ÿ“– Iraโ€™s Talmud Daf Yomi | Trello
