Compared to the many precautions of the Purgatory, light fasting seems to be more casual. In fact, it is not advisable to blindly try either Purgatory or Light Fasting. Instead of light fasting, I think it is better to stick to a moderate light diet of daily meals. How to understand? First of all, it means more intake of grains and vegetables, especially grains and cereals, such as rice kernel. This is a good ingredient of medicine and food, which has the effect of strengthening the spleen and dispelling dampness. It is an open secret that National Medical Master He Ren has been eating rice kernel for years to fight cancer. Rice kernels can be cooked in porridge, soy milk, burned into rice, cheap, easy to buy, cooking is not difficult. With this type of ingredients to replace the high-fat, high-cholesterol food, the same can play a role in maintaining the body. Secondly, do not overeat, eat eight points full, belly stay two points hungry, this word we must have heard, but not many people can really do. We all go out to eat together, encounter delicious dishes certainly can not help but eat more, if it is a buffet, the evening is inevitably eaten full. From the health point of view, it is obviously not good. Another point is to cut out other unnecessary eating. For example, snacks, especially fried potato chips, dried fruit, etc.; and then such as late night snacks, especially barbecue and beer. If these light eating requirements can often be achieved, then light fasting is also superfluous.
