Medical students report a significant decline in healthy dietary, exercise, and sleep habits compared to their pre-matriculation status.

A cross-sectional survey of 401 medical students found that 70% did not eat as healthy and 79% did not exercise as much as they would like, with 48% and 57% perceiving their diet and exercise habits as healthier before medical school. Time constraints (88%), fatigue (73%), and cost (62%) were the most commonly cited barriers.
