1, the two degrees are different.
At the beginning, China paid more attention to monks, and his attitude towards Taoist priests was more inclined to myths and legends. In addition, in ancient times, there was a dynasty whose beauty was fat. Therefore, after that, there were many fat people in Buddhism, and monks began to attack the thin Taoist priests, which led to the poor life of Taoist priests at that time and no food, which led to the lack of popularity of monks, so they became thinner.
2. Worship in different ways.
Everyone knows that monks worship meditation. Sometimes they sit all day and often don't move. Sitting after a meal is easy to gain weight, not to mention monks do it every day. Taoist priests are different. Taoist priests prefer to be immortals, and immortals don't have to eat. Therefore, Taoist priests often skip meals and mostly eat pickles and steamed bread. In addition, Taoist priests pay attention to health and will not make themselves too fat. Therefore, most Taoist priests are thinner.
There are different reasons for becoming a vegetarian.
For monks, they are vegetarians who don't kill animals. Therefore, in their view, vegetarianism is a kind of cultivation. As long as it is done, there are no other conditions. But for Taoist priests, meat will form turbid qi in the human body, which will affect the function of meridians, so it supports vegetarianism. Even if you eat vegetarian dishes, you should pay attention to the digestion of this dish, so Taoists do exercise so that Taoists will definitely not get fat.
To sum up, most Taoist priests are thin and monks are fat, which are mainly the above three reasons, but this can only be said to be in line with the majority. A person's physical quality is not necessarily related to the above three points. After all, everyone's physique is different. We can't generalize from point to point, but we can only say that these three points are the influencing factors according to our own actual situation.
