One 20-minute talk before a holiday may keep the pounds off — a trial puts it to the test

This trial tests whether a single preventive nutrition and physical activity session, given just before a national holiday, can help university students with overweight or obesity avoid gaining fat during the break. The session mimics a typical public-health consultation and focuses on healthy eating and exercise recommendations tailored to the holiday period. Participants' body composition, eating habits, and activity levels are measured before and after the holiday to see if the brief intervention makes a difference.
