Well, there are plenty of occasions when you might feel the urge to eat. Oftentimes, we even do not think why it is now and here we want to eat anything within the perimeter of our eyes (or in the fridge). It can be the stress. It can be that we are tired after a long work day and walk into the kitchen, ready to indulge. It can be that we are at a wrong place at a wrong time: the so-called situational eating or indulging.
It was found that chewing gum for an hour a day before eating reduces the appetite to eat the equivalent of about 68 calories in each meal, without feeling hungry overload, without the need for compensatory intake of food throughout the day.
