The purpose of this study was two-fold: a) to explore the experience and meaning-making processes of individuals who have maintained a weight loss and b) to explore how this learning manifested in successful weight maintenance and improved self-identity despite cultural stressors. This study was grounded in three intersecting theoretical frameworks relating to adult education: Transtheorectical Model of Behavior Change Transformational Learning Theory and Critical Media Literacy as informed by Critical Public Pedagogy. Narrative inquiry was chosen to study the nine stories of adult participants who successfully maintained a weight loss that bring meaning to the weight loss maintenance experience. The collective analysis resulted in two categories and five themes. The first category centered on adult learning. The first theme was related to triggers that were grounded by health and life events. Secondly, learning processes were evident in the narratives and were either self-directed, largely instrumental knowledge and occurred in a non-formal environment. Thirdly, weight loss was seen primarily as a physical transformation motivated by increased self-concept and helping relationships. The second category centered on hegemony and resistance. The fourth theme focused on cultural stressors including the fashion and entertainment industries. The fifth theme focused on changes in obesity discourse post weight loss. The study ends with a consideration of the findings in light of the theory for adult learning and practical implications for strengthening subsequent intervention design. iv TABLE OF CONTENTS List of Tables…………………………………………………………………...…………x List of Figures………………………………………………………………...…………..xi CHAPTER 1.
