Three-day light diet should be based on personal situation, physical condition, as prescribed by the doctor. Before fasting for three days, it is recommended to consult a doctor to confirm whether the body is suitable for fasting, and to understand your physical condition and limitations to avoid physical discomfort or health problems. Here are some recipes to consider: Day 1: Breakfast: oatmeal or brown rice with a cup of juice or black tea. Lunch: Steamed or roasted chicken breast or cod, with mixed vegetable salad and fresh fruit. Dinner: scrambled eggs with vegetables, steamed or grilled salmon, mushroom soup. The next day: breakfast: strawberry blueberry jam with whole wheat toast, a cup of low-fat milk or soybean milk. Lunch: steamed or boiled prawns with vegetable salad and a cup of yogurt. Dinner: lean beef, steamed or boiled fish and braised dishes rich in vegetables. Day 3: Breakfast: an egg sandwich (including whole wheat bread, lettuce, tomatoes and eggs) with a glass of juice. Lunch: Roasted chicken breast, cauliflower and mashed potatoes. Dinner: Braised chicken wings and stew rich in vegetables. The above is for reference only, and the specific diet should be based on personal circumstances and doctor's advice. When eating on an empty stomach and light diet, you should also drink plenty of water, pay attention to maintaining a balanced nutrition and reduce the intake of calories and fat. If you feel unwell or have any health problems, you should consult your doctor in time.
