The heaviest ever sumo wrestler gave some health advice. Orora weighed 292kg when he retired in 2018. He has warned wrestlers to take better care of themselves. Orora told a newspaper that Japan's sumo wrestlers should eat less. Sumo wrestlers have big appetites. Orora said wrestlers should think about their diet. He said they should reduce their calories. He said: "It's never easy to stay healthy as long as you're living the life of a sumo wrestler."

Orora said a sumo wrestler's lifestyle can be unhealthy. He put on weight by eating two big meals a day that contained over 7,000 calories. He ate 200 pieces of sushi with lots of beer. He also ate extra bowls of rice. This gave him hypertension. He said: "I would lie down and nap right after eating, which wasn't good. Just walking or moving was really troublesome." Japan's sumo association said wrestlers should eat more fish and vegetables and avoid snacks.
