KSI Hires Conor McGregor's Chef For Logan Paul Fight Prep

KSI is eating like the Notorious leading up to his rematch with Logan Paul ... hiring Conor McGregor's personal chef to cook his meals leading up to the fight!!

The 26-year-old British internet superstar gave an inside look into his insane training program for the Nov. 9 bout ... revealing he hired combat sports superchef Eric Triliegi to help him get in fighting shape.

"When it comes to cooking, we needed to upgrade the nutrition," KSI said on DAZN's "40 Days: Behind-The-Scenes With KSI" docuseries.

"We needed something more performance-based and that's why we decided to get Eric in."

As we previously reported, KSI says he's spent $300k of his own money on boxing training and other fight preparation expenses ... dude's taking this extremely seriously.

Chef Eric -- who's worked with pro fighters like McGregor, Anthony Pettis and Miesha Tate -- gave a breakdown on the diet he's cookin' up for KSI ... and it doesn't hurt that the food looks BOMB.

"Our main goal is to give fighters food that enhances performance. If we're not doing that, then why are we even here feeding them?"

Logan also kept the cameras rolling for his 'Countdown to Fight Night' docuseries with DAZN ... which shows the intense training he's been putting into the rematch. There's a cool moment where he puts on the 10 oz. gloves for the first time.

"This shouldn't be allowed. I swear to God, this shouldn't be allowed," Logan said ... saying the 2 oz. glove difference from the 12 oz. gloves they rocked in the first fight will give him a huge advantage.

Logan also had Elvis Grant Phillips -- founder of Grant Boxing Worldwide -- over to his mansion to try on a sick pair of silk-lined gloves, which Elvis says is a first of its kind.

"I feel like I am holding a gun in my hand."
