In my master's thesis, I examined the correlation of individuals’ eating behavior with his general life satisfaction and work-related outcomes, where I focused on self-perceived work efficiency, work engagement and absenteeism. The survey included 230 individuals that worked full-time. They completed Screening Questionnaire on Eating habits, General Life Satisfaction Scale (SWLS), Utrecht Work Engagement Questionnaire (UWES) and Short Form of the The World Health Organization Health and work performance questionnaire. The results of the study showed statistically significant correlation of eating behavior with work engagement, self-perceived work efficiency and general life satisfaction, but not with absenteeism. Linear regression showed that eating behavior is a statistically significant predictor of all of these variables, with the exception of absenteeism. Participants who were eating healthier reported greater life satisfaction, greater work engagement and higher work efficiency. The results are of primary importance for employees, as they confirm that nutrition is important for achieving good work results, and that healthy eating leads to greater work-related outcomes and greater life satisfaction. Findings also bring vast importance for employers since they confirm positive effects of health promotion at the workplace, which have beneficial consequences for both employees and employers. The results can thus represent an incentive for a healthier way of eating and can promote healthy nutrition. In the future, it would be suitable to repeat the study and to examine a potential correlation between eating behavior and other constructs.
