Fast food consumption is one of the factors which have been reported as a cause of obesity. Body mass index (BMI) is used to assess obesity and overweight, which can be calculated by using the formula, weight in kg, divided by square of height in metres. AIM: This study focused on the relationship of body mass index with fast food consumption, associated soft drink consumption and physical activity. METHODS: Descriptive cross-sectional study was conducted in Department of Biochemistry, SBKS MI and RC, and Sumandeep Vidyapeeth. This study was approved by the ethical review board .One hundred and forty seven medical students from 1(st) year MBBS course were included in this study. Self-structured questionnaire was used, which contained several data like information on age, height, weight, education level. The formula used for calculating BMI was, weight in kg, divided by square of height in metres (Kg/m(2)). RESULTS: In our study, out of 147 students, a total of 138 students (more than 90%) used to have fast food. Among these, a total of 47 students (34.05%) were pre-obese and obese. Out of 147 students, 87 students (59.18%) were in normal weight range, while 13 (8.84%) students were underweight. STATISTICAL ANALYSIS: Data was compiled in an Excel worksheet and it was analyzed for percentages and proportions. Chi-square and Pearson's correlation test were also applied wherever they were applicable and Alpha error was set at a 5% level. CONCLUSION: In our study, a significant relationship was found between BMI and fast food consumption, less physical activity, and intake of soft drinks.
