Why do we always tense up when we hear the word “calorie”? Definitively, a calorie is just a unit of heat that we use to describe how much energy our bodies get from eating or drinking it. We spend so much time counting them, reading about them and thinking about them, that sometimes we forget about the food itself and just plain eating healthy. Typically, most people think that the fewer calories they consume, the more weight they will lose. Then, they focus on killing those calories at any cost. However, the real cost could be the damage it could do to your metabolism and overall ability to lose weight – thereby defeating the real goal.
