Calories are energy you derive from foods or drinks you consume and just like we have innumerable varieties of foods, drinks and beverages, there are many different types of calories.

That said you will be interested to know that some fats are healthier than others. Vegetable oils for example are said to be better for your heart than their saturated counterparts or solid fats. Thus substituting solid fats with liquid cooking fats in your diet will do you a lot of good.

Another good idea would be to substitute fat spreads on your bread or burgers with non-fat spreads. For example, think of using margarine instead of cream or butter and so on.

Some calorific foods contain more calories than others. For example, saturated fats such as solid fats contained in many animal products contain some of the highest amounts of calories you can ever consume. Unsaturated fats on the other hand, such as olive oil, sunflower oil, fish, soya beans and nuts have high amounts of calories. Trans fat or hydrogenated fats mainly contained in processed food substances such as snacks are also known to contain processed calories linked to notorious health ailments. The fatty substances contained in animal products such as fat meat, eggs (especially the yolk), butter and so on are very rich in cholesterol.

Sugary drinks and beverages like sodas, sport and energy drinks on the other hand consist of too many empty calories that will not add any nutritional value to your body. The thing is, high calorie substances, be they drinks or foods, give your body a lot more energy than their low calorie counterparts. So unless you know where to empty those excess calories your body does not need, you should be watching your diet closely.
