The data were analyzed using Interpretative Phenomenological Analysis (IPA). The participants described their experiences in terms of six broad themes: their weight histories; the use of willpower to maintain weight loss; the factors that deplete willpower; the factors that increase willpower; how willpower had been strenghtened over the maintenance period; the differences when employing willpower during weight loss and maintenance. The results suggest that willpower has a major role to play in maintenance of weight loss and health professionals could increase the effectiveness of weight management interventions through willpower enhancement
