Novak Djokovic's strangest food and drink comments, from 'magic potions' to swearing at water

Djokovic reportedly switched to a gluten-free diet after failing a strength test while holding a piece of bread.

Yes, you did just read that right.

In 2010, Djokovic met with Dr. Igor Cetojevic, a Bosnian Serb, who believed Djokovic's frequent physical breakdowns in matches was due to a wheat allergy.

Cetojevic told Djokovic to put one hand against his stomach while holding the other straight out with his palm up. Cetojevic pushed down on this hand and told Djokovic to resist the pressure, which he did easily.

Cetojevic then told Djokovic to do the same thing while holding a piece of bread against his stomach. This time, Cetojevic said he easily pushed Djokovic's hand down.

"He was clearly weaker," Cetojevic said. "It showed that his body was resisting the wheat."

In Djokovic's 2013 book "Serve to Win" – which details his strict gluten- and dairy-free diet – the 34-year-old wrote how he believes it is possible to turn pure water green by directing negative energy (swearing, anger, fear) at it.

"That test is proof that every single thing in the world shares the same kind of energy," he wrote.

Just as he believes it is possible to turn water green with negative emotions, Djokovic also thinks it is possible to purify water with positive ones.

Speaking during an Instagram live interview with wellness guru Chervin Jafarieh in May 2020, Djokovic said: "I know some people that through that energetical transformation, through the power of prayer, though the power of gratitude, they managed to turn the most toxic food or maybe most polluted water into the most healing water, because water reacts, molecules in the water react to our emotions."

At the time, Jafarieh was selling $50 bottles of Advanced Brain Nutrients, reported iNews.
