Shevet HaKehosi: Seudah Shlishis, When Enough Is Enough
Seudah Shlishis while being one of the three meals you are required to eat on Shabbos still has some leniencies in the way you can be Yotzei your chiyuv to eat this Seudah.  Kiddush is not required according to most Rishonim, some say bread is not required, and some even say you can be Yotzei with fruits.  Although the Shulchan Aruch says one should wash and eat Lechem Mishneh nevertheless if one is exceedingly full he may be Meikil and eat fruits without washing.

Based on the opinion of Tosfos, the Shevet HaKehosi (2:121) says that the Shulchan Aruch would distinguish between someone who is nauseous to the point where he cannot look at food and someone who is simply extremely satiated and has no appetite for more food.  In the first instance he says you should not wash on bread.  This would be considered "Achilah Gassa" gorging and not eating, which is not considered eating at all (even on Yom Kippur).  So even if you ate you wouldn't get the mitzva.  Moreover he quotes the Pri Megadim who brings from the Shela HaKadosh that you are oveir on three aveiros for gorging yourself with food.  However if you can manage to eat fruit under these circumstances you can be Yotzei your mitzva.

If you are just very satiated he says, then you should wash and eat bread.  In any event says the Shulchan Aruch (OC 291:1) a wise man has enough foresight to control himself during the morning meal in order to leave enough room for Seudah Shlishis.  This way you can be Mikayem the Mitzva of Oneg Shabbos Kihilchoso, L'Sheim Shamayim and not L'Sheim your belly!
