AB  - OBJECTIVES: Behavioral weight loss (BWL) programs are the recommended treatment 
      for obesity, yet it is unknown whether these programs change one's ability to use 
      self-control in food choices and what specific mechanisms support such change. 
      Using experimental economics methods, we investigated whether changes in dietary 
      behavior in individuals with obesity following BWL are driven by one or more of 
      the following potential mechanisms: changes in the perception of the 1) health or 
      2) taste of food items, and/or 3) shifting decision weights for health versus 
      taste attributes. Therefore, we compared these mechanisms between obese 
      participants and lifetime normal weight controls (NW) both before and after BWL. 
      METHODS: Females with obesity (N = 37, mean BMI = 33.2) completed a food choice 
      task involving health ratings, taste ratings, and decision-making pre- and 
      post-standard BWL intervention. NW controls (N = 30, BMI = 22.4) completed the 
      same task. RESULTS: Individuals with obesity exhibited increased self-control 
      (selecting healthier, less tasty food choices) post-treatment. However, their 
      rates of self-control remained significantly lower than NW. We found no 
      differences in initial health perceptions across groups, and no changes with 
      treatment. In contrast, taste ratings and the relative value of taste versus 
      health decreased following treatment. Although, post-treatment participants 
      continued to perceive unhealthy foods as tastier and used less self-control than 
      NW controls, they showed significant improvements in these domains following a 
      BWL intervention. CONCLUSIONS: To help individuals improve dietary decisions, 
      additional research is needed to determine how to make greater changes in taste 
      preferences and/or the assignment of value to taste versus health attributes in 
      food choices.
