Jennifer said she followed a 100% vegan diet for five weeks and felt incredible. "It was a real change," she said. "I felt better and individuals were like, 'Your energy's better.'"

'Vegan Diet Will Change Your Life'

Lopez has since begun incorporating some protein into her diet, but sticks to a mostly vegan diet because it has motivated her to consume more fresh vegetables.

"The the fact is, even if you're 70-80 percent vegan, it is so much better having those vegetables, greens, and plant-based stuff," said Jennifer. "It's going to change your life and health."

Lopez was so excited about going vegan that they put her whole family around the 100% plant-based diet, including her twins, Max and Emme, and her sister, Linda. Lopez substituted almond milk or rice milk for cow milk and ate vegan cheese instead of dairy cheese. Her diet also featured plenty of greens, seeds, and nuts.

"Jennifer does the Tracy Anderson Method, including muscular structure work and between nine and 13 different exercises that change every Ten days, and dance aerobics too," said Anderson. "I keep [her butt] toned as well as in position. We all do planks, moving the legs and butt at different angles."

Tracy has sculpted some of Hollywood's fittest bodies, including Gwyneth Paltrow, Victoria Beckham, and Kim Kardashian. Anderson shared her weight loss tactics in her own book, Tracy Anderson's 30-Day Method.

Lopez's foray into veganism was inspired by the 22-day vegan diet challenge Beyonce and Jay-Z undertook in December 2013. The 22-day vegan cleanse was designed by Beyonce's trainer, exercise physiologist Marco Borges, creator of the 22 Days vegan protein bars, which Beyonce is a huge fan of.
