Study Objectives: The present study aimed to analyze the differences in the perception of life satisfaction (LS) and healthy nutrition attitudes (HNA) of university students according to general practice physical activity results. Analyzing the effect of HNA on LS was another aim. Materials and Method: A cross-sectional questionnaire survey was administered to Hatay Mustafa Kemal University students, and randomly chosen 498 university students participated in the study. The data were analyzed with SPSS 23.0. In the analysis of the data, One Way ANOVA and Simple Linear Regression were used. Results: According to the analyzed results, 32.9% of the participants were found to be physically active and reported significantly higher life satisfaction than physically inactive and moderately inactive students. Physically inactive students reported lower healthy nutrition attitudes than moderately active and active students. Healthy nutrition attitudes significantly predict life satisfaction for all participants regardless of their physical activity index. Conclusion: To achieve substantive life satisfaction, healthy nutritional attitudes should be developed.
