Sumo wrestlers follow a highly structured diet to support their intense training and build large body mass. Their main traditional meal is called chanko-nabe, a protein-rich, calorie-dense Japanese hotpot stew made with various meats like chicken, pork, fish, or tofu, along with vegetables such as cabbage, mushrooms, and daikon radish. This stew is typically accompanied by large amounts of rice and sometimes noodles for additional carbohydrates. Sumo wrestlers eat two large meals a day—one after morning training, then a rest or nap to encourage weight gain, and another in the evening before bedtime. Breakfast is often skipped to increase appetite for the main meals. Besides chanko-nabe, they consume calorie-dense side dishes including fried foods (tonkatsu, tempura), grilled meats, pickled vegetables, and fermented soybeans (natto). Beer is also commonly consumed with meals to add extra calories. Overall, their diet is high in protein, fats, and carbohydrates, designed to replenish energy, support muscle recovery, and promote weight gain essential for sumo wrestling.
