Eating small meals on Shabbos

Hi,

We are instructed to create pleasure on Shabbat; this is the mitzvah of oneg Shabbat. Where an action would bring pleasure to the body but disturb one's psyche, or vice versa, psychological/emotional pleasure trumps physical pleasure.

Therefore, one who would derive physical pleasure from eating, but who does not want to eat, may eat the minimum for the three meals of Shabbat and stop with that.

(Rivivot Ephraim 1:223:5)

Have a great day,
Mordechai
