Today is Jay Z’s 44th birthday, and last night, he posted a note on his Life + Times website claiming that he and his wife Beyoncé are making a life change, at least temporarily: They’re going fully vegan for 22 days. It would be pretty amazing if they’d come to this change of heart because they’d been reading all the stuff Morrissey’s been writing lately, but no: the physiologist and Jay buddy Marco Borges has an initiative called the 22Days Project, based around the idea that 22 days are all you need to break a particular habit. Below, read Jay’s note and watch Jay rapping about what he’ll be missing.

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.

I will let my friend Marco explain the benefits of a plant based diet here.

Now let’s all anticipate the moment Jay jumps into the Grimes debate.
