Before you start a water fasting regimen, you should first pay attention to your health. People with any health problems should do it under the guidance of a doctor. Fasting may be risky for some people, especially those with diabetes, heart disease or other chronic diseases. Here is a basic water fasting plan template: ### Preliminary preparation (3-7 days) 1. **Dietary adjustment**: Gradually reduce the intake of high-sugar, caffeine and processed foods. Increase the proportion of fruits, vegetables and whole grains. 2. **Water intake**: Start to increase your daily water intake to help your body adapt to the water needs during the fasting period. 3. **Physical adjustment**: If you don't exercise normally, arrange light activities every day, such as walking. ### During the fasting period (1-3 days) 1. **Water intake**: Drink at least 2-3 liters of water every day, in small amounts several times. 2. **Rest**: Get enough sleep, relax as much as possible, and avoid strenuous exercise. 3. **Physical reaction**: Pay attention to your body's reaction. If you feel dizzy, extremely tired or other discomfort, you need to stop fasting immediately and consult a doctor. 4. **Monitor your health**: measure basic physiological indicators such as weight and blood pressure. If conditions permit, you can do a basic health check at any time. ### End fasting (1-2 days) 1. **Gradually resume diet**: In the initial stage, you can eat liquid foods such as juice and broth, and then gradually transition to solid food. 2. **Dietary precautions**: Avoid greasy and excessive diets, and choose easily digestible foods such as porridge and well-cooked vegetables. 3. **Observe your body**: Pay attention to your body's reactions. If you feel uncomfortable, seek professional medical advice. ### Later adjustments 1. **Diet plan**: Develop a healthy and balanced diet plan and avoid excessive intake of high-sugar and high-fat foods. 2. **Stay hydrated**: Continue to maintain an appropriate amount of water intake. 3. **Regular life**: Add moderate exercise and other healthy lifestyle habits to maintain good health. In any case, if you feel uncomfortable or have other health concerns, please stop fasting immediately and consult a professional medical staff. Fasting is not a health strategy suitable for everyone, especially for those with special health needs.
