A dilemma was raised before the Sages: If there is among the members of a group one of them who has fine hands, a euphemism for one who always hastens to take a large quantity of food, what is the halakha concerning whether they can say to him: Take your allotted portion to eat and leave; and don’t take any more from the other’s members portions?
In our case, having “fine hands” means that he has the ability and reputation of taking more than his share.
This leads us to a review of gluttony and surfeit in antiquity down to modern neurobiology of food addiction.
