Investigating the importance of self‐acceptance and self‐efficacy on weight management in a developing country

The growing rates of obesity in both developed and developing countries are alarming. Most studies on obesity mainly focus on individuals in developed countries with ready access to food. Limited studies explore obesity in developing countries with limited access to healthier foods. In addition, studies show self‐acceptance and self‐efficacy are essential to healthier well‐being. The purpose of this study is (a) to explore the impact of self‐acceptance on individuals' self‐efficacy to weight management and (b) to investigate the impact of self‐efficacy on individuals' attitude and intention in regard to weight managements. Using data from Indonesia (N = 499), the respondents are divided based on their body mass index. The results show that self‐acceptance significantly influenced individuals' self‐efficacy, especially for individuals who are obese. Furthermore, self‐efficacy did not influence individual attitude toward weight management. Finally, attitude toward weight management only influenced people who are obese and not individuals who are overweight. The results of this study will have significant implications to government, social marketers, and not‐for‐profit organizations in fighting the epidemic in developing countries.
