A cross-sectional study was done on 1st-year MBBS students aged 19–21 year at SSMC, Tumkur with the approval of Institutional Ethics Committee. A modified questionnaire was circulated among 150 1st year MBBS students aged 19–21 years at SSMC, Tumkur through Google forms.

Around 46% of participants preferred weekend to consume junk foods. More than 50% of the participants consume junk foods when they are residing in hostel rather than home. More than 70% of the participants prefer junk food consumption during screen time.

Conclusion: Factors that have led to consumption of junk food are affordability and cravings. Preference of consumption of carbonated drinks with junk food is also high. The study also shows a strong association of junk food consumption with stress and screen time behavior. Due to its low nutritional value, junk food should be discouraged. Hence, awareness program should be included in to the curriculum of all medical students and in other professions also.
