This study aims to investigate the prevalence of weight control attempts along with their strategies and motivations. This study used a retrospective observational qualitative method, and adults who had body mass index (BMI) of at least 25 kg/m² were included. The qualitative data were analyzed using a descriptive phenomenological approach. The summaries and emergence of major concepts identified by the participants were analyzed in-depth using a systematized retrieval and review of the data. NVivo was used to establish interrater reliability and percent agreement and analyze and manage the data. 91.7% of participants had tried to lose weight, and 72% were successful at least in one of their attempts. Health, appearance, and sports training were salient motivating factors. Their attempts to lose weight ranged from 2 to 30 times (median 4 times). Different dietary strategies and physical exercises were often tried. Among the most notable strategies were diet methods, following weight management programs, and consulting with dietitians. A number of barriers were reported, including ineffective weight loss, non-sustainability, demotivation, and unaffordability. For advancing evidence-based long-term weight control, it is vital to evaluate the quality and nature of weight management strategies and services from the perspective of users.
