A tragic story has emerged from the fitness world after the death of Dmitry Nuyanzin, a trainer and influencer who reportedly consumed 10,000 calories per day as part of an extreme challenge. The news was shared by Dexerto, stating that the challenge was intended to demonstrate rapid weight-loss potential to his clients.
Nuyanzin, known for his upbeat personality and dedication to transforming people’s lives through training, began the experiment to document how quickly he could gain and then shed weight. His goal was to inspire those struggling with their fitness journeys by showing discipline, structure and the realities of drastic dieting. However, the extreme intake took a severe toll on his body.

The risks of extreme dieting challenges
The case highlights the dangers of pushing the human body beyond safe limits, especially for the sake of content or motivation. Excessive calorie consumption—particularly in the range of 10,000 calories per day—can strain the heart, liver and digestive system, and can rapidly spike cholesterol and blood pressure. Even well-conditioned athletes are not immune to the consequences of such severe experiments.
In the wider fitness community, Nuyanzin’s death has sparked conversations about the pressures influencers face to deliver dramatic content. Social media often rewards extreme challenges, rapid transformations and shocking numbers, encouraging individuals to take risks that may not align with long-term health.

As the story continues to circulate, it raises an important lesson: responsible guidance and sustainable habits must always outweigh extreme methods, no matter how motivational they may appear.
