month and 18 month between the two treatment groups were significantly different. Weight loss in high physical activity group reported in Jeffery (2003) is greater et al.’s than the results of trials reviewed in Catenacci and Wyatt’s (2007) study (0.1 kg to 5.2 kg in the exercise groups) and the result from previous review (Wing, 1999). It seems that a higher prescribed level of physical activity contributes to more weight loss. High of physical activity is a predictor of long-term weight loss maintenance (Wing & Phelan, 2005; Baak 2003). Losing body-weight is not the end of et al., combatting obesity epidemic; on the contrary, long-term weight regulation is also important to reversing the prevalence of obesity, especially for the people who were obese and have lost substantial body-weight lately. To learn how to successfully maintain long-term weight loss, Wing and Hill (Klem 1997) established the National Weight et al., Control Registry in 1994. The registry included more than 4,000 adults (aged 18 or above) who had lost at least13.6 kg and kept it off for at least one year. Wing and Phelan (2005) documented registered members’ behaviors related to long-term maintenance of weight loss. Engaging in high levels of physical activity was one of the most commonly reported strategies to maintain weight loss (The other strategies were low-calorie and low-fat diet, regular breakfast, regular self-monitoring of weight, maintaining a consistent eating pattern, and catching signs of weight regain before it gets out of control). Women in the registry reported an average of 2,545 kcal/week in physical activity, and men reported an average of 3,293 kcal/week. According to Wing and Phelan (2005), those levels of physical activity equal to about 1 hour/day of moderate-intensity activity, such as brisk walking. Other reported activities included weight lifting, cycling, and aerobics.
