Harley's clients, like everyone else, worry if they step on the scale and notice they've gained a pound, even if they're doing everything right. To avoid this problem, Pasternak doesn't weigh his clients until the end of the program. "Your weight fluctuates due to your hormone cycle, hydration, electrolytes and sodium intake," he said. "Don't feel defeated if your weight doesn't go down immediately. Be more concerned with the process. Did I do the exercise? Did I eat the things I was supposed to? If so, you're successful."
