Beyonce Knowles on plant-based diet

Pop star Beyonce Knowles has kept herself on a plant-based diet ever since she embarked on a 22-day vegan challenge, according to her personal trainer, Marco Borges.

The 32-year-old singer, who tried to become vegetarian for 22 days with her husband Jay Z until Christmas last year, is sticking to a plant-based food, reported E!Online.

"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," Borges said.
