First, the objects of worship are different.
Buddha statues such as Sakyamuni, Maitreya Buddha and Guanyin Bodhisattva enshrined in Buddhist temples are plump and round in face and figure, reflecting the aesthetics from the Northern Wei Dynasty to the Tang Dynasty. The chubby appearance is a natural psychological pursuit for monks to recite scriptures and seek to become Buddhas.
The appearance of Sanqing Tianzun and Zhenwu Emperor enshrined in Taoist temple is basically an old man with a sage style. Naturally, the ancestors worshipped by Taoists are similar in appearance, so they are generally thinner and have beards.
Second, the training concept is different.
Buddhism is a foreign religion, and the reason for its development in China is that it does not compete with the world. Monks pay attention to practice, meditate and recite scriptures all the year round, and naturally gain weight without exercise.
In addition, Buddhism believes that all body hair and skin are "smelly skin", which is useless after becoming a Buddha, so they seldom exercise. Taoism, a native religion, originated from Laozi's Taoist philosophy and pursued immortality. Therefore, Taoist priests pay attention to daily cultivation, practice qi and keep in good health, and the coordination of yin and yang in the body naturally becomes thin.
Third, different living habits.
The management system of Buddhism is more strict, and there are strict arrangements for doing everything in the morning, noon and evening. Moreover, monks generally live in temples and strictly control their words and deeds.
Taoist management is very loose. As long as you follow the instructions, you can decide where to practice. As a result, Taoist priests often live among the people, help the poor and help the chivalrous, and often help people exorcise evil spirits. In addition, most of the ancient Taoist priests knew martial arts, practiced Tai Ji Chuan and Taiji sword, and sometimes helped the country resist foreign enemies.

Personally, there is no difference between Buddhism and Taoism, and the fatness of Taoist and monk is not a problem. The fundamental reason why we believe in religion is to cultivate our minds. As long as we do more good deeds and help others, people will love and respect you whether you believe in Buddhism or not.
