If you are one of those people who simply cannot stop eating and never realize how much you have actually eaten, it ain't entirely your fault. Naturally, you have gained a lot of weight due to this, but you are unable to stop. What is going on? Well, rather that try to go on yet another diet or feel miserable for lacking self control or just giving up altogether, have you tried to find out if you could actually be sad or depressed? Scientists at the University of Wurzburg have found that when we are sad, we lose our ability to taste fat. So while normal, happy people can sense that a dish is fatty and heavy, and they stop eating when they feel full, unhappy people do not have that capacity, and never realize how much they have eaten. So stop feeling bad and work on your depression; the weight will take care of itself eventually.
