Beyoncé and Jay Z Are Going Vegan for 22 Days

Beyoncé and Jay Z are going vegan for 22 days, E! News reported Wednesday.

The rap mogul took to his Life + Times blog on Tuesday, Dec. 3 to share this development in the lives of the superstar couple. The move was inspired by Jay Z's 44^th birthday which is Wednesday, Dec. 4. He explained his reasoning for changing his dietary habits.

"Psychologists have said it takes 21 days to make or break a habit. On the 22nd day, you've found the way," Jay Z wrote. "On December 3, 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' every day. It was surprisingly easier on me than I thought."

The Watch the Throne rapper also explained why he waited so long to make this change, albeit temporary one. His reasoning was spiritual.

"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," he wrote.

At the end of the note, he added that his wife of five years, Beyoncé, would be joining him in becoming vegan for nearly a month.
