Reference for Yoma 160:3
מתקיף לה רבי זירא וכל העולם כולו בככותבת ועוג מלך הבשן בככותבת א"ל אביי קים להו לרבנן דבהכי מיתבא דעתיה בציר מהכי לא מיתבא דעתיה מיהו כולי עלמא טובא ועוג מלך הבשן פורתא
- R'Zera then asked another strong question: 'All the world' with a date and Og, the king of Bashan, also with a date? - Abaye replied: The Rabbis have ascertained that [touching food] the quantity [of a date] helps one to come to, but with a smaller quantity he will not come to; but, whereas all the world [can come to] more so, Og, king of Bashan, [only] somewhat so. R'Zera again asked another strong question: Fat meat in the quantity of one date and wine-branches also in the quantity of one date? - Abaye replied: The Rabbis have ascertained that one comes to with so much, but not with less; with [this quantity of] fat meat one becomes, however, more satisfied, whilst with the same quantity of wine-branches one becomes less so.
