On Yom Kippur, traditionally, one does not eat or drink at all during the fast, which lasts about 25 hours from before sunset the evening before Yom Kippur until after sunset on Yom Kippur itself. The fast includes abstaining from all food and drink. Exceptions exist for those with health conditions or other medical concerns, who may need to eat or drink in very limited quantities or follow a doctor's advice. Before the fast begins, people typically eat a pre-fast meal (Seudat Mafseket) that may include light, easy- to-digest foods such as chicken, fish, dumplings (kreplach), and round challah dipped in honey. After the fast ends, people break it with various foods depending on their cultural background—commonly bagels, fish platters, chicken, soups like Moroccan harira or Yemenite zom, and sweets like honey cake or cookies. If eating on Yom Kippur is medically necessary, one should eat minimal amounts (about the size of a small matchbox or 30cc) at intervals to sustain health while still attempting to observe the fast as much as possible. Therefore, the core practice is to abstain from food and drink completely during Yom Kippur, with eating only before and after the fast, and exceptions made for health reasons with very limited intake if required.
