Novak Djokovic
Views on diet, medicine and science

Since 2010, he has been connected with the nutritionist Igor Četojević who additionally focuses on Chinese medicine and performs acupuncture. He allegedly discovered that Djokovic suffers from gluten intolerance, using applied kinesiology, and that he should not eat gluten, removing it from his diet. He eventually settled on a vegan diet, while later sometimes eating fish. He also claims this vegan, plant-based diet cured his persistent allergies and mild asthma. The gluten-free diet has been credited for improving his endurance on the court and playing a role in his subsequent success.

Following his elbow surgery in 2018, he stated that he "cried for three days" after it, feeling guilty, because he was "not a fan of surgeries or medications" and wanted "to be as natural as possible". He further stated his belief that human "bodies are self-healing mechanisms".

In his 2013 autobiography, Serve to Win, he wrote of a "researcher" who directed "anger, fear, hostility" at a glass of water, which turned "slightly green" after a few days, while also directing "love, joy" at another glass of water, which remained "bright and crystal clear" in the same period. In 2020, Djokovic spoke of his belief that "some people" used "prayer" and "gratitude" to "turn the most toxic food, or maybe most polluted water into the most healing water." He also stated that "scientists proven" that "molecules in the water react to our emotions" and speech. Such claims are scientifically dubious, and generally regarded as superstitious beliefs.
