Calories are a unit of measure for energy from food, and thus, if your calorie expense for eating the item is higher than your calorie gain from the item it would be considered a “negative calorie food”.  Each food has a certain energy contant (remember portion size is also a factor here).  Additionally, any unused energy will be stored in the body (and often turned into fat).  People use a fair number of calories (or amount og energy) just for their basic bodily functions throughout the day. Then additional calories are burned based on metabolism, health, and activity level.  To maintain the same weight you would need to consumer roughly the same number of calories that you burn in a day.  Minor fluctuations that average out both ways over a short period of time are generally not noticed.  However, if you are always eating a calorie defecit, or surpluss you will notice changes in your weight.
