Music mogul JAY-Z and Beyoncé are all about those vegan goals. The duo have challenged fans to consider adopting a more plant-friendly lifestyle in 2019.

According to reports, the couple push for the non-meat and non-dairy agenda in a new book by Bey’s fitness trainer.

In an introduction for the new book The Greenprint: Plant-Based Diet, Best Body, Better World, by Marco Borges, Beyoncé’s trainer, the couple open up about how parenthood changed their outlook on life — including the food they eat. “Having children has changed our lives more than anything else,” they wrote. “We used to think of health as a diet – some worked for us, some didn’t. Once we looked at health as the truth, instead of a diet, it became a mission for us to share that truth and lifestyle with as many people as possible.” (People)

JAY and Bey encourage fans to consider adding more vegan options to their consumption habits over the next 12 months.

Stressing the fact that it takes more than just a few people to make a big change, the couples added that they “want to challenge you, as we challenge ourselves” to help make a difference. “We all have a responsibility to stand up for our health and the health of the planet. Let’s take this stand together. Let’s spread the truth. Let’s make this mission a movement. Let’s become “the Greenprint,” they concluded. (People)

Last year, Bey promoted her vegan lifestyle ahead of a jam-packed Coachella music festival performance.
