Obesity program. The hospital has a 6-month weight-loss program known as the obesity program (OB program). In this program, physicians, clinical psychologists, registered dietitians, and exercise trainers support obese patients. During the 6-month program, obese patients first consulted with a physician for blood and physical examinations. They then participated in intake interviews about their eating habits with a registered dietitian and about their current psychosocial condition with a clinical psychologist. At least once a month, the clinical psychologists met patients for individual face-to-face counseling. A meeting was held every month to discuss methods to support them and to improve their lifestyles.
