Prepare Your Body for Yom Kippur Fasting: Expert Dietary Advice

As Yom Kippur approaches, experts advise on how to prepare the body for the 25-hour fast to make the experience more manageable. Proper hydration and balanced meals in the days leading up to the fast are crucial, not just the final meal before it begins.

Throughout the day before Yom Kippur, it is recommended to drink water gradually rather than attempting to consume large amounts just before the fast starts. Meals preceding the final one should include filling foods like rice, potatoes, bread, or whole grains, complemented by a protein source. While vegetables add volume and fiber, it's advised to avoid experimental diets. For coffee drinkers, a gradual reduction in caffeine intake is suggested to prevent headaches, rather than an abrupt stop.

The final meal, known as the "se'ah מפסקת" (se'ah mafseket), should focus on satiety rather than sheer volume. A balanced combination of carbohydrates, protein, and healthy fats, such as rice or potatoes with chicken, fish, eggs, or legumes, along with vegetables and a source of fat like tahini, avocado, or olive oil, is recommended. Eating slowly is also advised to prevent discomfort and heaviness.

Foods to avoid before the fast include very salty items like processed snacks, sauces, and high-sodium foods, which can increase thirst. Spicy or excessively heavy foods may also cause heartburn or discomfort. Sugary sweets and drinks are not recommended as they do not provide lasting fullness.

Breaking the fast should also be done gradually. Starting with water and easily digestible items like soup, bread, yogurt, or fruit is advised. A larger, heavier meal immediately after the fast can lead to bloating, nausea, and stomach pain. If still hungry, one can eat more later. Similarly, rehydrating should be gradual, starting with water and continuing throughout the evening.

Ultimately, a successful Yom Kippur fast involves consistent hydration, a balanced pre-fast meal, and a gentle return to eating afterward. The article also notes that if significant symptoms like confusion, fainting, or unusual weakness occur during the fast, it should be broken and medical help sought.
