Brief Summary:
The pilot study will be a one group treatment program and will be utilized to refine the M+BWL program.

Condition or disease Intervention/treatment Phase
Overweight Obesity Behavioral: Memory + Behavioral Weight Loss Not Applicable

Detailed Description:
The investigators have developed a new model for the treatment of obesity, which emphasizes the role of memory on food consumption in an overweight population.The pilot study will be an open label trial of a memory+behavioral weight loss (M+BWL) group treatment. The treatment will be administered in 14 group sessions over 16 weeks. The investigators will recruit adults with overweight and obesity and will assess them at baseline (prior to treatment), during treatment, post-treatment (immediately following treatment), and follow-up (3 months after treatment). Assessments will include body mass index (BMI), body composition, and binge eating over the course of treatment and follow-up. This study will contribute to the study of basic behavioral mechanisms and food intake, could provide a novel model for the treatment of obesity, and could inform clinical decision making regarding obesity treatment.

Arm Intervention/treatment
Experimental: Memory + Behavioral Weight Loss (M+BWL)
The M+BWL program will integrate memory interventions to the BWL program. The BWL program will include dietary recommendations, physical activity recommendations, and behavioral change recommendations.
Behavioral: Memory + Behavioral Weight Loss
BWL and memory enhancement (M+BWL) will be integrated to capitalize on the strengths of both treatments. All participants will be taught general behavioral weight loss skills including to decrease caloric intake and increase physical activity, self-monitoring, goal setting, managing high-risk situations, meal planning, slowing eating, problem solving, social support, cognitive restructuring, lapse and relapse prevention skills, and maintaining weight loss. The proposed M+BWL program provides memory interventions based on the literature, including eating attentively, memory of previous meal, memory skills for planning, effects of diet on memory and the relationship between memory and satiety. The M+BWL program will also utilize experiential learning during the group program such as practicing memory enhanced skills during eating.
Other Name: M+BWL

Primary Outcome Measures :
  1. body mass index as measured by height and weight [ Time Frame: Change from baseline at an average of 4 months and 7 months ]
