Methods: In this study, demographic and anthropometric data along with the results from medical examination were extracted from the employees’ health records. Weight and height measurements were obtained using a weighbridge scale for determining body mass index (BMI). A frequency food questionnaire (FFQ) was used to measure the employees’ dietary intake. Chi-square and Kruskal-Wallis non-parametric tests were also employed to investigate the relationship between the indices. Results: The results showed that 71.8% of employees were overweight and obese. Furthermore, 25.60% were shift workers, and 34.60% had performed jobs involving static work. According to the LDL, triglyceride and cholesterol levels, 37.2%, 51.3%, and 39.8% of employees were respectively at risk of developing serious illnesses. Based on the Chi-square test, there was a significant correlation between the BMI and the employees’ job (static or dynamic) (P value 0.05). Likewise, there was a significant correlation between the level of triglyceride and BMI (P value 0.05). There was also a notable relationship between employees’ BMI and consumption of fast food, soft drinks, fat and oil, sugar, and pastries and cakes (P value 0.05). Conclusions: It is evident that implementation of integrated programs, such as educational, motivational, and physical strategies along with promotion of healthy eating, will prevent BMI increase and incidence of fatty liver among employees.
