A video posted on YouTube by Guinness World Records shows Mr Reddy smashing 212 walnuts with his hand as the 60-second deadline looms and a hopeful crowd looks on.
Rows and rows of walnuts were placed neatly on a long wooden table and, according to Guinness World Records, inspected by independent witnesses beforehand to ensure all the walnuts were raw and undamaged.
In order to count towards the final tally, the shells of the walnuts had to be smashed into a minimum of two pieces.
The 35-year-old martial arts pro told Guinness World Records that he practised every day before the attempt.
Mr Reddy successfully broke the previous record of 210, which was achieved by Pakistan's serial record-breaker Muhammad Rashid.
Guinness World Records admits that while challengers for the title are allowed to wear a fabric glove on their crushing hand, the attempt is likely to be painful "even for the most experienced of martial artists."
"Wonder how his hand felt after smashing all of the nuts," asked one person on YouTube. "Wow! This is nuts," joked another. "Forget about the record, look how organized the nuts were," laughed a third. Click for more trending news
