Nowadays, working conditions have a negative impact on employees’ eating habits, as well as on their health status and ability. The main objective of this study was to investigate whether Dr. Sears’s diet affects employees’ physical manifestations. Data were collected from a sample of 100 employees who were employed by different companies in the broader area of Attica, once a week, for a period of three weeks. Of those who participated in the study 44% were female. The results showed that Dr. Sears’s diet had a beneficial effect on the participants’ physical symptoms. This diet normalized the physical symptoms from the stomach and musculoskeletal system, the fainting tendencies, shortness of breath, low energy levels and difficulties in sleep. Future research should include personal (e.g. Big 5 Personality Traits ) and environmental (e.g. working conditions) factors for the best possible improvement in occupational health.
