Understanding Calories
A calorie, known as a kilo calorie, is a unit of energy. This unit represents the energy required to heat a kilogram of water one degree Celsius. In fact, it is a unit of measurement applied to any substance with energy despite people understanding that it always connects to food. For instance, a normal quart of gasoline possesses 8200 calories.
Calories describe the potential energy in food to maintain bodily function, grow or repair tissue, and perform mechanical work for the body such as exercise. Food calories may take the form of fat, carbohydrate, or protein. Once consumed, through metabolic processes, enzymes act on these nutrients and break them into fatty acid, glucose, and amino acids, respectively. These molecules travel through the bloodstream to specific cells where they are absorbed for immediate use or sent on to the final stage of metabolism where they release their stored energy through the process of oxidation.
The number of calories burned during exercise depends on various factors including body weight and the type of exercise. For example, an individual weighing 59 kilograms (130 pounds) would use approximately 500 calories per hour running or playing football. However, the same person would burn an estimated 200 walking or playing table tennis. In order to maintain body weight, the average individual requires approximately 2000 to 2500 calories per day.
