Jay-Z and Beyonce's Three Week Vegan Diet

Famed couple commits to changing their eating habits for a set period of time.

One of Hollywood’s most famous para-couples is jumping on a trendy diet bandwagon; Jay-z and Beyoncé have started a 3 week plant-based diet.

You gotta wonder how committed they are to the vegan lifestyle with Beyoncé apparently spotted wearing fur and swayed the other day, which is a big no-no in the vegan world. ABCs’ Abby Budroll takes a closer look at the diet on everybody’s lips these days.

Super star couple Jay-z and Beyoncé are joining forces yet again, this time on a vegan cleanse, a plant based diet with no animal or dairy products. Holy grail, the holy grail artist who turned 44 on Wednesday posting on his personal website life and times, that he and B are embarking on a 22 day challenge to go completely vegan or as I prefer to call it, plant-based, Beyoncé even sharing photos on Instagram, chronicling the challenge.

Jay-Z and Beyoncé are notoriously private about their lives together, so it is unusual that they are being so public about what they are going to be eating.

Jay-Z says on his website, ”This all began a few months back when a good friend and vegan challenged me to embrace a plant-base breakfast every day.” That good friend is his trainer and nutritionist Marco Bergius, the mastermind behind this 22-day cleanse, who says that plant-based nutrition is better for the environment and your body. His website inviting readers to take the 22 day challenge with daily vegan menus. I met with nutritionist Rachel Guller who says going vegan can be tricky.

Some of my patients gain weight on a vegan diet.

Oh why is that?

Because you’re eating things that could be fried, could be sweet potato fries, still fattening.

She showed us two meals, one vegan, the other clearly not. But cautions when you go vegan, you need to get plenty of protein.

It’s about balance and knowledge. So you know, you just wanna make sure that you’re not getting the wrong foods.

Calling it a spiritual and physical cleanse, ending on Christmas day, Jay-Z promises to post his progress. But makes no promise about his plant-based future, posting we’ll see, best of luck and health. For good morning America, Abby Budroll, ABC News, Los Angeles.

Ok, if there was any doubt that this couple is probably the most famous couple in the world, the fact that we are intrigued by what they eat, I mean, you are famous, but I don’t really ask what you ate last night.

Yeah. Right and I can guarantee you it wasn’t interesting.

We’ll see if they hold up to this, it’s an interesting challenge for them.
