The goal of both organizations taking part in the project is to support 26 people aged between 13 and 20 in achieving their mutual desire - to meet in order to promote an active and healthy lifestyle in outdoor and sports fields. Polish and Greek youth group made contact through interest groups on Facebook. Initially, they contacted virtually, using Skype and other instant messengers, but after the winter holidays, they decided to lead to a joint meeting enabling the exchange of skills and knowledge in their needs and interests. Young people struggling with problems of obesity, overweight, low awareness of a healthy diet decided to conduct anonymous surveys and interviews among Polish and Greek teenagers, in the group of youth aged 13-20, attending schools of people involved in this project. The number of respondents was 262, 157 (59.9%) girls, and 105 (40.1%) boys. Participation of students in the study was voluntary. The study showed that up to 40% of students never eat meals on a regular basis and only 11.5% declared their regular consumption. Less than half (46.9%) of respondents declared daily consumption of breakfast. The most commonly eaten meal was dinner (n = 217, 82.8%) and supper (n = 143, 54.6%). Most students (77.5%) did not know the correct classification of the pyramid of nutrition floors. This study showed abnormal nutritional behaviors of Polish and Greek youth. Young people from partner countries conducted interviews and on-line discussions and got acquainted with numerous publications on physical activity from adolescence to adulthood and ways of spending free time. They admitted that most of them limited their physical efforts in everyday life, including locomotor activities. The development of new and more and more attractive technologies causes immobilization of teenagers for many hours a day, from the youngest age of life. Travelling to school and less and less outdoor activities with peers causes a decline in physical activity and healthy eating habits among young people, many health problems. That is why, it is highly justified to think about ways to implement appropriate measures in the field of health prevention, aimed at improving youth eating habits and developing habits of an active, sporting lifestyle. The youth agreed that during the week of a joint meeting in Poland, they would increase their awareness of the importance of sport, healthy food, ecological awareness, in accordance with the objectives of the Erasmus + program and the 2020 horizon. The goals and needs of young people and want to solve thanks to the implemented project are in addition to promoting a healthy, sporting and sustainable lifestyle at the European level: - learning from each other, among others good attitudes, cooperation in a group, communication, overcoming barriers, setting goals and ways to implement them, accepting failures, searching for new solutions, - sharing experiences, - developing responsibility for performing assigned tasks (eg. a person responsible for the team), - shaping the sense of equality of all members in the group, overcoming shyness, insecurity, - development of creativity and entrepreneurship, development of openness attitudes and communication skills, - improving the skills of building social relations, - improving English skills, - mastering basic knowledge of new foreign languages (Poles - Greek, and Greek - Polish), - getting to know the culture, customs of the youth of a European Union country (Greece and Poland), - the development of a sense of European citizenship and identity, - care for good physical condition, fitness, outdoor activity, health and well-being, - the importance of healthy eating in everyday life, - developing the ability to use various media (internet, press, meetings), - creating awareness about the Erasmus + program and increasing the participation of young people in it.
