Social pressures. Yes, being hungry is uncomfortable and even can hurt, but if you ignore it long enough, it can sometimes become a bit more like background noise. I have always been a healthy weight, but my entire life I have had the paranoia of becoming fat. And so I am very accustomed to feeling hungry. When they started me a psych med that people can easily gain weight on, I started monitoring my weight more closely. Often, I go to bed with hunger pangs.
