Reducing Calorie Intake

Calorie is the amount of heat needed to raise the temperature of one liter of water by one degree Celsius. It is not a physical thing or object that is present in foods but a measure or a unit of energy that it contains. In foods, the use of calorie did not exactly mean this amount but 1000 times this. We can easily recognize which quantity they mean by looking at the “c” in calorie.

A normal calorie uses lower case while calorie with upper case “c” means kilocalorie.Another unit of energy is joule and in terms of calories, 4. 18 joule is equal to one calorie (Stern, 2005). Calories in food are always associated to fats.

The more calorie you take, the fatter or the heavier your will get. But calorie is the needed to do everything we need to do. It is our fuel. But our body does not used up all the calories that we get from the food that we eat. This excess calorie is stored in the body in the form of fats. An amount of 3500 calories will be stored as 1 lb of fat (Scott, 2007).We can reduce this excess energy by reducing intake of mare calories or by performing actions that would burn these calories.

In every food that we eat, calorie is always present. For example, a regular cheeseburger without mayonnaise has 320 calories (Collins, 2000). This is enough for a 50 kg man to climb a height of approximately 3 m. Not eating a cheeseburger would save you from this much calories and this kind of work. Now lets say that we want though exercise like jogging.

For a 154 lb man walking at a rate of 3.5 mph could lose 54 calorie after a distance of a mile. At this rate, he has to walk 6 miles to burn 320 cal. But by just sitting, our body can still burn this amount of calorie though metabolic processes (Brody, 2006). And so it can be seen that reducing the amount of calorie intake have greater effect on weight loss. Reducing calorie intake is the most important factor for losing weight. References Brody, J.
