"How do you stop eating?" a woman asked me the other day. Interesting question. She admitted that she had nothing but work in her life and she was lonely. Food was her one pleasure and comfort. She binges and makes herself feel unwell or orders far too much because she wants to taste everything and she thinks about food and what she can have more than is necessary.
Food is pleasure and then you move on to other things. I've told her before - "Get busy! Find things that interest you. You won't know until your try them and start meeting new people, making friends, having more life in your life." One of the best tools I use is that you simply learn to be your own parent. No one can do this for you. You get to jump in and start building that muscle just the same as physical muscles. At first it won't feel comfortable to tell yourself "No more." At first it might not be easy to push the plate away or stop eating. You do it because you get committed to having your life be different. If something is hurting you, walk away from the source of the pain.
You can hire a coach to keep you accountable but you still must do this for yourself. If you never learned how to stop eating. Now is the perfect time to begin. Stop giving yourself excuses. Stop creating problems for yourself and don't let old habits dictate how you live your life now. Remember that quote "The chains of a habit are too weak to be felt until they are too strong to be broken." Make good habits strong and let go of things that don't serve you. You can do it, you just have to begin and keep going.
