Goal of this work is to promote via on-line applications the knowledge of the Italian Weekly Pyramid, which is based on the concept of WI (Well Being Index) as a unit for a correct lifestyle. On the website the user can verify his/her weekly lifestyle by participating in a "game" based on the introduction, for seven consecutive days, of food and beverages consumption and time assigned to physical activity. At the end of the seven days it is possible to access the page with an evaluation of dietary habits together with the possible suggestions for a correct lifestyle. On the basis of the data collected through this web game, a statistical analysis has been developed to evaluate the food habits and the level of physical activity. In the period between September 2005-January 2010 16,546 participants have completed the game. The data collected compare actual WI consumption for each food group with the one suggested by the Pyramid. The sample eating pattern appears almost varied; all the food groups were consumed daily, albeit in much lower quantities with regard to the suggested portions. It is pointed out that some differences in the nutritional habits are related to differences in age groups and in the school degree of the sample analyzed. This work highlights the importance of web-based tailored interventions on population food habits: many people can be reached to promote the knowledge of the guidelines leading to a healthy lifestyle.
