To present results from a two year prospective study on diet, 6 months before and 18 months after retirement. The studied population exhibited an increase in social and physical activities over time after retirement. A significant decrease in weight was found in men 18 months after retirement. Retired individuals reported taking more time for breakfast. 45.5% of retired individuals, compared to 25.5% before retirement, took more than 30 minutes for lunch than before retirement. The amount of dietary nutrients consumed remained the same before and after retirement. However, retired individuals ate out more often, and had guests more frequently. Nutrients' distribution is similar before and after retirement. Given a life expectancy of more than 20 years after retirement, it is necessary to initiate nutritional intervention.
