The path to a healthier life may take you to Duke Diet & Fitness Center in Durham, North Carolina. Our medically supervised, residential-style weight-loss program gets results—and the numbers tell the story. Participants in our program lose an average of five percent of their initial body weight—often more. And that’s just while they’re here. Because our clients leave with the tools to continue living healthier lifestyles, studies show that 80 percent have maintained their results or continued to lose weight one year later.
