That should be an easy answer. We eat to fuel our body... or we should, anyway. With so much food readily available to us today, we eat for many more reasons.
This is one of the things you have to evaluate before weight loss surgery. A psychological evaluation is required by most insurance companies and/or doctors.
The common misconception is that once you have WLS, you are "fixed." Your issues with food go away. This is so far from the truth. Most people's reasons for being overweight has nothing to do with fueling their body. I still crave things I shouldn't have and I still get "the munchies."
I am an emotional eater - happy, sad, excited, depressed, nervous - you name it and I can eat my way through it. Since WLS, I've had to find other ways to deal with my emotions.
I also eat out of boredom. I have to find ways to keep my mind and hands busy or I will mindlessly eat. Rarely do I sit and watch tv. I'll watch tv while surfing the internet or playing a game on my phone. But just sitting - can't do it.
I also love to read. I can get caught up in the story line of a book and forget about what's going on around me. This keeps my mind busy and can be an outlet to soothe emotions.
Exercise is a great solution - if I exercised regularly. Still got to work on that one...
