Arms	Assigned Interventions
Active Comparator: 1 A 24-week intervention in which individuals will meet weekly to be instructed on behavioral change associated with weight loss, including modifying dietary intake, self-monitoring weight and eating behaviors, and increasing physical activity.	Behavioral: Standard behavioral treatment for weight loss A 24-week intervention in which individuals will meet weekly to be instructed on behavioral change associated with weight loss, including modifying dietary intake, self-monitoring weight and eating behaviors, and increasing physical activity.
Experimental: 2 A 24-week intervention in which individuals will meet weekly to be instructed on behavioral change associated with weight loss, including modifying dietary intake, self-monitoring weight and eating behaviors, and increasing physical activity.
