Beyonce definitely turned heads at this year's Grammy Awards in Los Angeles, where the 32-year-old superstar appeared slimmer than ever in a figure-hugging Michael Costello dress -- which the designer estimated was a "tiny" size 2/4.
So how did Beyonce get her incredible body?
Through the help of her trainer and nutritionist Marco Borges, the exercise psychologist and author behind The 22 Day Nutrition that challenges people to go vegan for 22 days. He recently talked to Beth Stern about how Beyonce and Jay-Z agreed to try their much-publicized lifestyle change.
"They're incredible human beings and we've developed a really beautiful friendship over the last seven years, and we were just talking about the benefits of plant-based nutrition, and health, and life, and I thought, it would be cool if I challenged them to a plant-based breakfast just one meal a day," he recalls. " ... A couple of months later it was so easy that they decided on their own to come to me and say, 'Hey, you know, your company 22 Days Nutrition, it stands for something that's taking on a new habit over the course of 21 days, and on the 22nd day something new happens, so it would be really cool if we try that challenge ourselves. We want to go plant-based.' And Jay says, 'Yeah my birthday is coming up, and I think it would be really cool, if for my birthday I just did this, like, spiritual health cleanse and I tried something new. ... it was amazing."
Borges attributes Beyonce's headline-making incredible physique at the Grammys to her diet.
"Most people have that imbalance," he says about how difficult it is to burn calories through exercise versus how easy it is to consume calories. "And it's when they take control of their diet is when they truly take control of their health."
