Brief summary

The present study aimed to investigate the effects of a single nutritional preventive session previous to a critical period linked to fat gain in university students with overweight and obesity, emulating a nutritional session of a public health system.

Interventions

OTHEREducational talk about physical activity and nutritional recommendations before a critical period of fat gain in university students

An intervention was performed emulating a traditional nutritional session from a primary healthcare center (public health system). Traditionally, this session lasts around 20 minutes and includes a body composition measurement, nutritional assessment, and a brief educational talk about healthy eating. Just the intervention group received a series of healthy recommendations specially focused on the National Holiday.
