This study had an aim to investigate the students' lifestyle and their knowledge of what a healthy lifestyle means. The research was made by 135 students from the "Ştefan cel Mare" University of Suceava, from economics faculties, 114 women and 21 men aged 18 to 32. The evaluation was based on an investigation, and as a research tool we used the questionnaire, which contained 20 questions. In this article, we will be concerned only with some components of lifestyle, namely eating and practicing the physical exercise of students. Research results have been awaited, especially with regard to the role of physical exercise in young people's lives. It has been discovered that most of the respondents do not practice physical exercise but only weekly or monthly, less than 10 minutes, the main activity being walking, few of them opting for sports games, working on fitness machines or walking bicycle. Physical inactivity, unorganized and high fat diet, makes this issue a national and global interest of the 21st century.
