ABSTRACT
Time-restricted eating (TRE) has gained popularity in recent years as a weight loss option. Although many studies have explored the effectiveness of fasting, few have investigated the successful implementation of this method. Therefore, the purpose of this study is to examine the successful and failed experiences of overweight adults who have implemented TRE for weight loss, in order to identify strategies for maintaining a favorable weight over time. The study utilized semi-structured interviews and followed Constructivist Grounded Theory to collect and analyze data. Data saturation was achieved through purposive and theoretical sampling of 30 overweight adults. The research confirms four stages in the process of weight loss using a TRE strategy, namely, preparation, adaptation, challenge, and maintenance. The findings revealed that the successful implementation of TRE and its maintenance over time require viewing TRE as a lifestyle rather than a tool for short-term weight loss, the development of specific action plans to overcome obstacles, and a positive attitude and self-belief as important sources of support. Based on the study's results, a guide has been provided for those who wish to use TRE as a dietary control method.
