I am not sure I am a compulsive eater, but I did use food for comfort and I am a chronic snacker, especially in the evenings.
The band is not a magic wand that will make that go away. The band is designed to reduce the amount of food you eat, but in order to lose weight, you need to follow the guidelines and eat protein, veggies, grains and fruit, in that order. Not to say that you can never have the foods you love in moderation or for a treat, but when you are striving to lose weight, I keep the treats to a minimum.
If you have compulsive eating issues, counselling may be available to help you overcome this or to distract yourself from eating by doing something else, like exercise, a walk or a bottle of water.
I made the decision to do this and was fully committed to change my lifestyle. I do have a treat once in awhile, but try to stay on track 99% of the time.
If you have any quesions at all, we are all here for you!!
Good Luck!
