Very few people realize that if you feel full, you've already eaten too much. For this reason, dieticians and nutritionists recommend slow, measured bites of food punctuated by long, full gulps of water. This guarantees that you never reach that extremely uncomfortable, bloated point that follows a hastily eaten and improperly enjoyed meal.
Increase your use of herbs and spices. Part of the reason "eating healthy" seems so unattractive is the perceived blandness of the food. The truth is, fat and salt are natural flavoring agents, so if you remove them you've got to start experimenting with herbs and spices until you've got healthy food that is full of flavor.
