"Jessica did a vegan diet for about two weeks leading up to the wedding," said a source. To boost her weight loss from her plant-based cleanse, she also worked out with celebrity trainer Harley Pasternak.
Famed for her toned legs, Jessica performed lunges regularly as well as upper-body work. She also wore a pedometer and aimed for 12,000 steps per day, which Harley recommends for all his clients.
Jessica isn't the only celebrity to choose a vegan diet for weight loss. Beyonce and Jay Z went on a vegan diet for 22 days, according to E News. In addition, Jennifer Lopez chose a vegan diet to shed extra pounds.
And while all these celebrity dieters also exercised, Jennifer's trainer Jay Cardiello disagrees with the latest studies that say it doesn't matter if you eat breakfast when it comes to weight loss. While doing cardio in the morning without eating might help you shed pounds temporarily, "it’s not sustainable," he said in an Aug. 22 interview with the Daily Beast.
Researchers have discovered that eating carbohydrates before you work out actually boosts your post-exercise "after-burn" more than fasting. That benefit means that you continue burning more calories during the day even after you've finished exercising.
If you do want to try the trend known as fasted cardio, Cardiello cautions that the method "shouldn't be used unless you are being looked after by a nutritionist, professional strength training coach and a medical professional." One of his clients, 50 Cent, used it but the trainer worked closely with the rapper to make sure he stayed healthy.
Jessica's trainer Harley feels that breakfast is essential. "Contrary to popular belief (and maybe counterintuitively) eating breakfast actually helps you lose weight," he said in a blog for People magazine.
Moreover, says Harley, studies show that eating breakfast helps prevent type 2 diabetes. That first meal also helps your metabolism function more effectively.
