When Dmitry Nuyanzin, a 30‑year‑old fitness trainer from Orenburg, Russia, posted his plan to consume roughly 10,000 calories a day, his 43,000 Instagram followers cheered. The goal was to bulk up by about 25 kg before shedding the weight alongside participants in his upcoming weight‑loss course. Within a month, the experiment turned tragic: Nuyanzin collapsed, suffered cardiac arrest and died in his sleep.
The Rise of Extreme Fitness Challenges
Social media has turned personal training into a spectacle. Influencers often promise rapid transformations, using shock‑value diets or workouts to attract clicks. In South Africa, similar trends coexist with everyday hardships; commuters are simultaneously coping with disruptions from crime and antisocial behaviour on public transport. The lure of dramatic before‑and‑after stories can eclipse the real health risks behind such stunts.
Inside the 10,000‑Calorie Diet
According to Nuyanzin’s own posts, his daily menu resembled a fast‑food marathon. Breakfast consisted of a plate of pastries and half a cake; lunch featured 800 g of dumplings drenched in mayonnaise; snacks were limited to crisps; and dinner was a burger accompanied by two small pizzas, either ordered in or eaten at a café. In total, the intake was almost four times the recommended daily calories for an adult male (about 2,500 kcal). Over roughly 30 days, his weight rose from 92 kg (202 lb) to 105 kg (231 lb), a gain of 13 kg (29 lb).
Health Risks of Overeating and Rapid Weight Change
Consuming excess calories, especially from saturated fats and refined sugars, can overwhelm the cardiovascular system. The British Heart Foundation notes that even modest weight gain raises blood pressure, cholesterol and the risk of type 2 diabetes, all of which are precursors to heart disease. When the body is forced to store large amounts of fat quickly, the heart must work harder, potentially leading to arrhythmias or cardiac arrest. Moreover, rapid weight fluctuations can destabilise electrolyte balances, impair kidney function and trigger inflammation.
Aftermath and Lessons for Influencers
Friends reported that Nuyanzin cancelled gym sessions and sought medical help shortly before his death, but he never made it to a clinic. His final Instagram story, posted on 18 November, showed him holding a packet of crisps with the caption, “I wanted it and I was able to!” The post quickly went viral, prompting other platforms to highlight the dangers of extreme dieting. The incident mirrors another recent case where an influencer died after a massive food binge, a story covered in the viral story of an influencer who died after a massive food binge. Both cases underline the responsibility that content creators have to their audiences.
Broader Context: Social Media, Health and Regulation
Fitness influencers often hold qualifications—from Nuyanzin’s graduation at the Orenburg Olympic Reserve School and the National Fitness University in St Petersburg—to lend credibility. Yet, without oversight, they can promote unsafe practices. South African regulators have begun examining how health advice is marketed online, echoing global calls for stricter guidelines. Public health experts suggest that platforms should flag content that encourages extreme caloric intake or rapid weight change, and that influencers should disclose medical supervision when undertaking such challenges.
In the wake of Nuyanzin’s death, his followers posted tributes praising his positivity and professional background. While his ambition to motivate others was clear, the tragedy serves as a stark reminder that extreme calorie surpluses are not a harmless shortcut to fame. Sustainable fitness relies on balanced nutrition, gradual progress and professional medical oversight—principles that no viral challenge should override.
