Not much different with a car that burns gasoline in order to move, your body also burns calories in the form of food to produce energy.
Nutritional experts measure the amount of heat generated by the body metabolizes food in a unit called kilocalories (kcal). We take the example of calories contained in a banana. Banana contains 105 calories, meaning that the banana metabolize, the body will produce 105 calories that can be used to move.
You may be wondering what foods contain high calories. The answer depends on what kind of nutrients they contain. For example, in 1 gram of carbohydrate contains 4 calories, 1 gram of protein contains 4 calories and 1 gram of fat contains 9 calories.
In other words, one gram of protein or carbohydrate provides more than half the calories of one gram of fat. This is why high-fat foods such as fried foods, have more calories than low-fat foods such as vegetables and fruits.
However, it is not always as easy as counting calories, the foods usually contain a variety of nutrients. Take for example, if you eat skinless chicken breast with a burger, both contain high protein. 100 grams chicken breast has 140 calories while weighing the same burger has 270 calories.
All food producing calories. All calories are energy. But not all calories as well carry nutrients such as amino acids, fatty acids, fiber, vitamins, minerals and other nutrients. Some foods even contain empty calories. This term is given in calories with little or no nutritional benefit at all, such as sugar and ethanol (alcohol contained in the liquor). Sugar and ethanol provide energy but without any nutrients.
Be wise in choosing a healthy source of calories and right for your body. If you want to lose weight, calorie intake should amount not greater than the energy you put out, because if he had the body of excess calories are stored as fat. So, start counting your calories now!
