I feel like the serenity prayer, which is said in every AA meeting, perfectly addresses this : God, grant me the serenity to accept the things I cannot change,  Courage to change the things I can,  And wisdom to know the difference. Accepting yourself means accepting the aspects of you that you cant change (race, sexuality, etc) but also having the courage to change the things you can (i.e weight). If only these delusional hambeasts knew the difference.
