The aim of this thesis is to analyse the body culture / physical culture of young people in the context of social media from a Christian-ethical perspective. It will start with describing how social media influence young people concerning social approval, entertainment, information, identity-finding and communication. Then, I will give a description of both the ideal of beauty portrayed on social media and its negative effects such as eating disorders, depression, self-objectification, heteronormativity, narcissm, anti-obesity bias and neoliberal ideologies.As beauty standards are often unrealistic nowadays, they are rather hard to meet, which leads to social pressure. To hold against this, the concept of self-acceptance (Romano Guardini) will be put forward. Possessing self-acceptance means accepting one's imperfections and being emphatic with oneself.In addition, in this thesis arguments will be brought forward that support the claim that from a Christian point of view joy, happiness and gratefulness for creation can help to overcome the pressure having to follow the ideal of slenderness, which is often associated with radical diet and extreme physical exercise.Finally, it will be discussed that from a Christian perspective, authenticity is a desirable value that helps to reduce pressure to conform to body standards. However, as shown in my analysis, risks still remain on social media as authenticity can only be realized there to a certain extent due to reasons of privacy. The beauty industry itself, on the other hand, could easily show more authenticity when making advertisements so that the audience will not be deceived.
