Jay Z and Beyonce announced Tuesday they will cut meat and other animal products from their diet for the next 22 days, in search of “a spiritual and a physical cleanse.”

“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!!” the Brooklyn rapper wrote on his Life and Times website.

The vegan lifestyle entails eating absolutely nothing from animals, including dairy products.

The married couple will embark on this 22-day journey that ends on Christmas. Their reasoning behind the number 22? The number four is important to the Carters, as both of their birthdays fall on that particular date, hence the reasoning behind 22 days “2 + 2=4.”

For those who are interested in the vegan lifestyle and aren’t as educated on the eating habits (as Hov himself has admitted) can follow Jay Z’s updates on his website.

“I will post my progress… Any professional vegans out there that have any great food spots please help out! Please ha,” Jay wrote. “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…”

Can you go without animal products for 22 days?
