I used to always eat enough to feel full and never experience hunger!
Then one day my friend was dieting and he called me up in a panic, worried that he had an ulcer. He described his symptoms: a weird feeling in his stomach, hearing lots of funny noises, inability to concentrate on other things.... I told him what he was experiencing was probably hunger!
He was amazed. He said that he hadn't experienced hunger in years, possibly decades. I was amazed!! Since then, I've made a big effort to be more in touch with my body and its signals!
How often do you experience hunger?
