Yom Kippur Fast: Expert Tips to Avoid Discomfort During and After

As Yom Kippur approaches, Israelis are advised to avoid common mistakes that can make the 25-hour fast more difficult. Naturopath Lilach Serzo highlights that over-consuming water or food just before the fast begins is counterproductive. Drinking large amounts of water right before the fast does not create a reserve, as healthy kidneys will simply excrete the excess. Similarly, a very large final meal can lead to discomfort, bloating, and heaviness before the fast even starts. Instead, a balanced, regular meal with complex carbohydrates, protein, vegetables, and moderate fats is recommended.

Sudden caffeine withdrawal can cause headaches, drowsiness, and irritability. Serzo suggests gradually reducing caffeine intake from coffee, strong tea, and energy drinks in the days leading up to Yom Kippur. Taking large doses of vitamins is also ineffective for creating reserves and should be avoided unless medically indicated. Individuals on regular medication should consult a doctor before altering their dosage or stopping treatment for the fast.

Post-fast recovery is another critical period. Immediately consuming a large meal after the fast can lead to stomach pain and bloating. Serzo advises a gradual return to eating, starting with fluids, then light foods, before a full meal. Special caution is urged for individuals with chronic illnesses, those taking medication, pregnant or breastfeeding women, and the elderly, who should consult a physician about fasting and medication schedules.

In 2026, Yom Kippur begins on the evening of Sunday, September 20, and concludes on the evening of September 21.
