Awareness IS an important part of the solution, but an incomplete one. There are lots of people who are ALREADY AWARE of their emotional eating problems, but they feel unable to stop them. The first step towards freedom from emotional eating is to develop conscious awareness. Your ability to change inappropriate eating behaviors (eating for the wrong reasons), starts with your understanding that you have been unconsciously eating without even realizing it.
Emotional eating is nothing but comfort eating. If you're at the point where you can't resolve the issue, you need to find ways of nurturing yourself and pampering yourself that are not food related. Find a substitute for food and distract yourself with playing an sport, painting or sketching, solve puzzles or play video games, etc.
It is important to understand that this not physical hunger craving but an emotional one.
