Beyoncé Knowles has partnered with leading fitness trainer and exercise physiologist Marco Borges to launch vegan meal delivery service 22 Days Nutrition.

Knowles took the 22 Days Nutrition challenge in 2013 along with husband Jay Z, during which time the pair ate plant-based meals for 22 days, based on the philosophy that it takes 21 days to make or break a habit. She commented 'I am so grateful that I took the challenge and credit Marco with leading by example. He is the most energetic person I know and it's all because of his decision to live a healthy lifestyle. He came up with a great program to get people motivated to make better nutritional choices. All you have to do is try. If I can do it, anyone can. I am excited to partner with him'.
