Mahlzeiten zum Abnehmen auslassen: Ist es eine Sünde?

Christianity's dieting ethics works the middle of a vice-sandwich: gluttony on one side (a classical deadly sin, defined more by appetite's disorder than by weight), and self-harm/neglect on the other (the body is a temple, 1 Corinthians 6:19-20 — a text written for sexual ethics but applied to every bodily practice since). Between them sits a broad valley of freedom: sensible eating, portion discipline, even intermittent fasting — which the tradition invented, in both mandatory (Lent) and voluntary forms. The meal-skipping analysis therefore asks medical rather than merely moral questions: does the pattern improve or damage the body God entrusted? Contemporary Christian writers add a third rail the ancient texts did not name: body-image idolatry — weight-control pursued from shame or vanity rather than health, which the tradition files under neighbor-love's failure to extend to self, and under the 'fear of man' (Proverbs 29:25). The tradition's clearest modern teaching concerns eating disorders: anorexia and bulimia are treated as illnesses that diminish or remove moral culpability — the response is medical and pastoral care, not discipline — and churches are explicitly counseled to drop both the gluttony-shaming and the thinness-idolizing that feed them.
