Jessica worked with celebrity trainer Harley Pasternak to lose weight. In September 2019, he revealed that the singer was taking 12,000 steps a day, getting at least 7 hours of sleep every night and crushing circuit workouts. Her meals were full of “protein, fiber and healthy fat,” while snacks had “protein and fat or protein and fiber.”

“There is no magic diet that is the end all and be all,” the fitness expert added. “If you take enough steps per day, you don’t need to starve yourself food-wise, and if you eat properly, you don’t need to run a marathon.”
