Dietary fasting, a practice derived from Daoism, is becoming increasingly popular for promoting health. When done correctly, fasting can yield significant benefits. But what constitutes the correct way to fast?
Length of Fasting
Fasting can be categorized into short-term, medium-term, and long-term durations. Short-term fasting typically lasts 3-7 days, medium-term fasting lasts 8-14 days, and long-term fasting lasts 15 days or more. Advanced fasting involves complete abstinence from both food and water, while intermediate fasting allows for water consumption. In contrast, low-level fasting permits a small amount of fruit intake, and those undergoing long-term fasting can supplement their diet with dried fruits such as dates and walnuts. Beginners are advised to start with short-term fasting and gradually progress to longer durations. It is also recommended to undergo specialized training under the guidance of an experienced teacher.
Semi-Fasting
Semi-fasting allows for the consumption of water and honey, as well as small amounts of melons, peanuts, walnuts, dates, hazelnuts, almonds, and other medicinal foods. The goal is to avoid feeling hungry. This type of fasting is suitable for first-time fasters or individuals with weak constitutions and multiple illnesses.
Near Semi-Fasting
In this approach, cooked food is largely avoided, while fruits, vegetables, and other miscellaneous foods can be consumed freely. Porridge, noodles, and vegetarian dishes can also be included in the diet. This method is particularly suitable for individuals with psychological barriers or extremely weak constitutions.
Complete Fasting
During this stage, it is best to abstain completely from both food and water, allowing the body to exchange energy and information with the external environment while fully mobilizing its potential to carry out various metabolic processes. However, this type of fasting is rarely practiced and should only be undertaken under the supervision of a well-trained practitioner. Safety precautions should be prioritized, and it is important to avoid excessive hunger. Blindly pursuing the duration of fasting is strongly discouraged.
Near Complete Fasting
In this approach, small amounts of water and honey can be consumed, and limited fruit intake is allowed. However, pills and grains should be avoided. Near complete fasting can be practiced by individuals with varying constitutions and generally offers a higher level of safety.
Post-Fasting Reintroduction of Food
To prevent rebound effects after fasting, it is advisable to avoid overeating and aim for a feeling of satiety at each meal. During the first two to three days of reintroducing food, easily digestible liquid foods are recommended. Once the digestive system has adapted, solid foods can be gradually reintroduced. It is best to avoid excessively salty or spicy foods and prioritize a vegetarian diet while minimizing the consumption of meat and seafood.
