Fitness influencer, 30, dies of heart failure after binge-eating 10,000 calories to gain 25 kg

A Russian fitness trainer and influencer died in his sleep after forcing himself to consume extreme quantities of junk food in a controversial bid to prove the effectiveness of his weight-loss programme.

Dmitry Nuyanzin, 30, from Orenburg, reportedly ate up to 10,000 kilocalories a day for weeks as part of a self-imposed “marathon” challenge. His goal was to gain at least 25 kg before demonstrating how quickly he could shed the weight — a stunt he hoped would inspire his clients. But his heart failed as he slept, according to Russian outlet Ostorozhno Novosti.

Nuyanzin shared his daily meals with thousands of followers on a Russian social media platform, revealing a diet heavy on processed foods. “For breakfast, I have a plate of pastries and half a cake. For lunch, I usually eat 800 grams of dumplings with mayonnaise. During the day, I may snack on crisps, and for dinner, I have a burger and two small pizzas,” he wrote earlier this month, as per the Daily Mail.

By November 18, he announced his weight had reached 105 kg — a gain of at least 13 kg in one month. His challenge rules promised that anyone weighing over 100 kg who lost 10 percent of their body weight by the New Year would win 10,000 rubles (about Rs 11,500), paid directly by him.
