Feeling powerless around food is about avoiding to accept and deal with your emotions. It will lead you to eat to numb your feelings and fill a certain void. It can be triggered by anxiety, fear, uncertainty, boredom, disappointment, anger, and other emotions that are not very easy to deal with. Learning to know your triggers, accepting, understanding and comforting yourself is key to have a healthier relationship with food and feel better on all levels
