Dmitry Nuyanzin, 30, decided to eat 10,000 calories a day – nearly four times the recommended 2,500 daily intake for men – all to try to promote his weight-loss programme, but tragically died, with his official cause of death yet to be confirmed

A 30-year-old influencer tragically died following a shocking challenge in which he attempted to gain 55lbs by consuming 10,000 calories daily, before shedding the weight as part of an extreme fitness experiment.
Dmitry Nuyanzin started a campaign that saw him consume 10,000 calories each day — nearly four times the recommended daily intake of 2,500 calories for men — in a bid to promote his weight-loss programme.
The fitness personality, who had built up a following of more than 43,000 Instagram subscribers, aimed to showcase the effectiveness of his programme by offering $100 to anyone weighing over 220lbs who successfully shed 10 per cent of their body weight by New Year’s Eve, according to Perth Now.
Feasting on burgers, pizza, chips, pastries, and dumplings smothered in mayonnaise, Dmitry managed to pile on at least 28lbs in just one month, ballooning from 202lbs to 231lbs in that time.
He dubbed it his junk food ‘marathon’. Launching the challenge towards the end of last year, Dmitry told his followers: “Friends! My WEIGHT LOSS COURSE is starting very soon, where you can win awesome prizes and, most importantly, build a beautiful body, learn how to eat well, and enjoy working out! I’ll be losing weight with my students, so it’ll be doubly exciting!”, reports the Daily Star.

Throughout the challenge, Dmitry kept his followers regularly updated, posting images of himself consuming high-fat meals. Describing his dietary regime in one post, Dmitry, who lived in the Russian city of Orenburg, said: “I am currently gaining weight for my weight-loss course, and this is my 10,000-calorie diet.
“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, either at a café or delivered.”
In his final Instagram post, uploaded on November 18, the social media influencer was shown clutching a packet of crisps while rubbing his stomach, alongside the message: “I wanted it, and I got it!”

Tragically, according to accounts from the Ostorozhno Novosti channel, Dmitry experienced cardiac arrest during sleep and passed away.
This happened just one day after Dmitry called off his gym appointments, informing friends he was experiencing ill health and planned to consult a doctor. He has since been laid to rest in Orenburg, with heartfelt tributes flooding in for “an amazing person”, described as “bright” and “positive”.
One social media commenter posted: “It is better to prove such theories not in practice. Rest in peace.”

Another said: “It’s true. If you’re not used to junky fries, fast food, it will indeed make you sick” A third individual observed: “Well, if ever there was a cautionary tale, then this has to be it.”
The British Heart Foundation cautions that carrying additional weight can present serious risks to your heart. According to their website: “It can lead to fatty material building up in your arteries (atherosclerosis), increase your risk of high blood pressure, high cholesterol and type 2 diabetes. These are also risk factors for heart disease.

“If the arteries supplying blood to your heart become damaged and blocked, it could result in a heart attack. If this occurs in the arteries supplying blood to your brain, it could lead to a stroke or vascular dementia.”
Dmitry graduated from the Orenburg Olympic Reserve School and the National Fitness University in St Petersburg, according to Mail Online. Throughout his career, he reportedly trained members of the Russian elite and motivated his substantial online following.
It’s understood that Dmitry was married and had no children. His official cause of death remains undisclosed at present.
