Calories and Kilojoules

Understanding caloric needs is an integral part of weight loss. Research over the years has proven — whether diets focus on fat or carbs — that calories still count. Why? Regardless of what diet you’re following, if you take in more calories than you need … you gain weight. The daily recommended caloric intake for the average American maintaining their weight is 2,000 calories, give or take a few: Men can eat a little more, women, less. Your specific, individual calorie needs depend on several factors such as your activity level and metabolism. Calories are found in four components of foods. They are: fat, carbohydrates, protein and alcohol (i.e., sugar). Fat contains twice the calories of carbohydrates or protein.

We eat food to fuel our bodies for energy, growth and repair. Carbohydrates, proteins and fats are broken down by the digestive system into their simplest components: simple sugars, amino acids and fatty acids. Carbohydrates are the body’s preferred fuel, although proteins and fats can also be converted into energy. Food energy is measured in kilojoules (kJ). The common term for this used to be ‘Calorie’, but ‘kilojoule’ is the term now accepted internationally. This unit of measurement allows us to talk about how much energy a food contains and how much energy is burned up during exercise.
