Sumo wrestlers only eat two meals a day, both at noon and at night, which are hot pots. This kind of hot pot is called ちゃんこ hot pot (Lux hot pot). ちゃんこ originally refers to all kinds of diets specially prepared for sumo, and later it is gradually considered as hot pot. This is a typical nutritious meal, in which beef, fish, bean products and vegetables are stewed in a large pot. Because it is cooked, easy to digest and absorb, and rich in nutrition, it can be said that this is a very healthy diet.

Sumo has become so fat mainly because they drink hot pot soup as water.

Moreover, a big sumo wrestlers can eat the equivalent of 5.6 people. Some sumo wrestlers will eat a lot of desserts such as cream cakes when they are full, and go to bed immediately after eating. In this way, it is difficult to get fat.

But this alone is not resistant to fighting. Sumo wrestlers train for more than five hours every day, do some very intense fitness exercises, and practice very intensely. Fitness exercise is basically to destroy and tear tendons and meat, and then let them grow up. Moreover, after a long-term collision, sumo's forehead is relatively flat and particularly hard. So "big fat people" are all fat and fat, with thick muscles.
