Dmitry Nuyanzin has sadly passed away.

The Russian fitness coach died at the age of 30 amid a binge-eating challenge to gain weight, according to a new report.

Dmitry reportedly suffered a fatal cardiac arrest in his sleep amid a challenge to eat 10,000 calories a day and gain 25 kilograms (over 50 pounds), then lose the weight with his new fitness program.

He had reportedly cancelled training sessions one day before his death as he felt unwell and planned to see a doctor according to messages sent in the Ostorozhno Novosti Telegram channel, via The Daily Mail .

Three days afterward, he was laid to rest in Orenburg, Russia.

He had been documenting his dramatic weight gain and loss efforts online, detailing his diet that included pastries, dumplings, burgers and pizza.
