Background: This study was conducted to evaluate the effect of a weight loss method in individuals who successfully lost weight and determine the mental health problems that might have occurred while losing weight.
Methods: Data were obtained from the Seventh Korea National Health and Nutrition Examination Survey in 2016. First, an independent sample t-test was used with continuous data to identify the relationship between successful weight loss and the general characteristics of all participants, and the chi-square test was applied to categorical data. Second, a logistic regression analysis was performed to determine the relevance of eight successful weight loss methods based on the variables that can affect weight change such as age and sex. Similarly, a multivariate logistic regression analysis aimed to determine the correlation between mental health problems and successful weight loss.
Results: The results showed that adhering to an appropriate dietary regime and taking oriental medicines significantly influenced weight reduction. Other methods such as skipping a meal, taking prescribed medicines or health supplements, and following a mono-diet have no noticeable effect on weight loss. Moreover, the analysis of factors affecting mental health that could influence the environment and lifestyle of the dieter has indicated that there is no positive association between these factors and actual weight loss.
Conclusion: A controlled diet is recommended as an effective treatment for weight loss rather than skipping a meal or fasting and taking oriental medicine. The factors associated with weight loss may not cause mental health problems.
