Fasting is one of the most common resolutions people make. But how exactly the temporary abstention from eating works and which method suits you, only very few fasting people know. dr Daniela Koppold, 39, is a co-founder of the Academy for Integrative Fasting at the Berlin Charité and works in research and teaching.

The doctor, who fasts herself and also works as a lecturer at the Immanuel Hospital in Berlin, explains in an interview with WELT which fasting method is best for you and why diets are harmful to the body.
