NEW YORK: Beyonce has a ‘’mostly plant-based diet’’.  The ‘Drunk in Love’ singer tried out becoming vegan for 22 days with her husband Jay Z in the lead up to Christmas and has since mostly kept to it, according to Marco Borges, her personal trainer.  He told E! news: ‘’She is all about health and wellness. She just wants to feel good. The transition [from vegan] was fairly easy because [now] she’s sticking to a mostly plant-based diet with some fish here and there.’’  Although Jay, 44, is thought to have gone back to eating meat, he does like to support Beyonce by hitting the gym with her whenever possible.–EN
