In August 2017 Dzhambulat weighed 230 kg and decided to lose weight. His goal was to lose up to 120 kg. By his 18th birthday he had lost 54 kg and weighed 176 kg, achieving this together with the trainer Yusif Nurullaev. He said: "The trainer literally kept track of every portion of food I was about to eat. I photographed my plate with my phone before eating and sent it to Yusif. If I forgot to do this, it means that he believed that I ate more than allowed, and loaded me more during training session. This disciplined me a lot."
