In brief: Food is fuel

Different cars get different miles per gallon, and different people get more or less out of each calorie they eat.
If your engine burns more calories, it will take more food to fuel you. Sometimes this is just your particular metabolism, and sometimes something can be wrong, like an overactive thyroid, that burns the calories you eat faster. Check with your doc or a dietician.
