The 39-year-old comedian - who lost six stone before he moved across to the US - is planning to go completely vegetarian in the near future by phasing out fish.
He said: "I'm going to try to phase out fish next. It's going to be a gradual process."
However, since eliminating animal products from his diet, he's realised that he's become more reliant on bread to help curb his hunger during meal times.
Meanwhile, James recently invited Sir Paul McCartney on his show's 'Carpool Karaoke' segment so the pair no doubt had plenty to talk about in between takes as the 75-year-old musician is a long-time vegetarian and animal rights activist.
The Beatles legend has tried to encourage other people to follow a vegetarian diet over the years as he previously banned animal food products from his rider.
The meat-free demands were reportedly part of the terms and conditions of Paul playing in the province of Saskatchewan in Canada in 2013 - meaning he wouldn't perform unless show organisers confirmed no meat would be eaten backstage.
He also made a similar demand in 2002 when he was on his 'Driving' USA tour as he said he didn't want any furniture in his dressing room to be made of animals.
It reportedly said: "It is crucial you do not provide furniture made of any animal skin or print. Do not provide artificial versions of animal skin or print either. Only animal free materials are excepted. (cottons, denims, velour, etc.)"
