    Abstract

    Objective: An effective program for preventing metabolic diseases through lifestyle modification is urgently needed. We investigated the effects of the Life Style Modification Program for Physical Activity and Nutrition program (LiSM10!®) on metabolic parameters in middle-aged male Japanese white-collar workers. Methods: One hundred and one male office workers, 30 to 59. years of age, with metabolic syndrome risk factors, were randomly allocated into no-treatment control (n=49) and LiSM intervention (n=52) groups. The LiSM group attended individualized assessment and collaborative goal setting sessions based on food group intake and physical activity, followed by two individual counseling sessions with a registered dietitian and physical trainer, and received monthly website advice during the 4-month period from December 2006 to May 2007, in Tokyo, Japan. They were encouraged to enter current targeted food intakes and pedometer data on self-monitoring websites during the entire study period. Results: Habitual food group intakes changed significantly in the LiSM group, showing improvements in 14 anthropometric and biochemical parameters contributing to inter-group differences in body weight, body mass index, fasting plasma glucose, insulin and homeostasis model assessment of insulin resistance changes (p<0.01). Conclusion: The LiSM10!® program effectively improved insulin resistance-related metabolic parameters in middle-aged male white-collar workers.
