The project “Healthy outside starts from the inside” was implemented to increase our awareness of how to lead a healthy lifestyle. Its aim was to develop solutions concerning regular physical activity, taking care of proper nutrition, accepting one’s own body, harmfulness of stimulants and the connection between diseases of civilization and an improper lifestyle. In it, we tried to instill healthy eating habits, counteract obesity and serious diseases resulting from neglect of the body and increase the frequency of physical activity. The project was based on activities, actions, simulations, discussions and meetings prepared by individual groups, partly in cooperation with experts in the field close to the subject of our project. During the exchange, we tried to exchange observations, experiences, work on greater independence and a good future and encourage the wider community to get involved in the subject of our project and spread knowledge about leading a healthy lifestyle. In our project, we focused on both the physical and mental condition of the body and raised the issue of lack of acceptance of one's body, which is becoming increasingly popular among young people and turns out to be fatal in its consequences for the psyche of a young person. By implementing social campaigns and local events, we wanted to motivate each other and other people to fight for their health and promote self-acceptance among young people.
