Almost 95 % students agree that obesity causes systemic diseases such as diabetes and hypertension which will ultimately lead to cardiovascular problems.Chi square test was done between gender and people who are following a healthy diet and exercising daily where p<0.05 which is statistically significant.Our study showed that almost all students were aware about sedentary lifestyle and its complications, but the females in the study have shown that they do not follow a healthy diet and do not exercise regularly which makes them prone to obesity and ultimately cardiovascular problems. To avoid these problems, awareness has to be spread in colleges about the seriousness of obesity and its harmful effects and how to prevent it.
