The superstar rapper made the decision to switch up his eating habits ahead of his 44th birthday, which is today (4 December), and claimed that the "plant based" challenge is particularly significant because of the number of days involved.
Writing on his Life+Times website yesterday (3 December), Jay explained: "Psychologists have said it takes 21 days to make or break a habit. On the 22nd day, you've found the way.
"On December 3rd, one day before my 44th birthday, I will embark on a 22 Days challenge to go completely vegan, or as I prefer to call it, plant-based!! This all began a few months back when a good friend and vegan challenged me to embrace a 'plant-based breakfast' everyday. It was surprisingly easier on me than I thought…
"Why now? There's something spiritual to me about it being my 44th birthday and the serendipity behind the number of days in this challenge; 22 (2+2=4) coupled with the fact that the challenge ends on Christmas day…It just feels right!
"So you can call it a spiritual and physical cleanse. I will post my progress… Any professional vegans out there that have any great food spots please help out! Please ha. I don't know what happens after Christmas. A semi-vegan, a full plant-based diet? Or just a spiritual and physical challenge? We'll see…
"Best of luck and health! P.S. B is also joining me."
The '99 Problems' hit maker then shared a link for others who may wish to read up on the benefits of going vegan.
So we guess that means he won't be indulging in any birthday cake today? Gutted!
Meanwhile, Jay and Beyoncé were spotted grabbing a bite to eat yesterday at a restaurant in Los Angeles.
Bey looked effortlessly cool (as always), as she flaunted her killer legs in a tiny pair of leather shorts and donned a patterned leather jacket with white sleeves.
She also left her light blonde hair down in loose, messy waves and sported some chunky black boots with cute leopard print socks.
The mother-of-one is currently in LA on her 'Mrs. Carter Show' world tour.
