One phrase that seems to be fashionable amongst the overweight is "emotional eater".I suppose they are stating that they eat when the experience an emotion. I am curious to know if there is any moments when they are experiencing the void of any emotion. Being human, I too , experience a wide range of emotions. However, I don't necessarily equate eating a cup cake as a way to negate the negative feeling.
Feelings can alter from one experience to the next. There are going to be times in our life when things happen that we may not be too happy about—but can recognize that emotions are temporary. And when they go you will still be here. Ready to experience the next one.
What you are feeling should not dictate what we are going to eat, or how we feel about ourselves, health etc.
Eating a bag of chips or cookies will not make the "feeling" go away. It may change your focus for ten minutes, but you can change your focus by engaging in any activity. The truth is covering your feelings by eating something unhealthy will only make you feel worse. You are causing yourself to be trapped in a cycle. Whatever is troubling you WILL change. But the consequences of what you choose to do about it may linger for much longer.
