Milk is fine, too?

Yamamotoyama relegated to chanko-nabe chef

Former Makuuchi rikishi, Yamamotoyama, has gone from sekitori status to head chanko chef at the Onoe-beya in the span of two basho. Yamamotoyama sprained the anterior cruciate ligament in his left knee during the Nagoya basho
causing him to withdraw from that tournament and miss the Aki basho altogether. The result is his current rank of Makushita 13 and obligation to help with the menial duties around the stable handled by non-sekitori. Yamamotoyama has stepped in as the stable's chief chanko-nabe chef although he claims to be on a diet where he doesn't eat any rice and only consumes light meals throughout the day. His keiko also consists of walks around the neighborhood, but Yamamotoyama's goal now is to lose a bit of weight and make it back into the Juryo ranks. He holds the record for fattest rikishi all time at 266 kilograms.
