Calories Per Pound -

A calorie is the unit of measurement of energy. Though, in most fields, it has been replaced by joule, it remains in common use for the amount of energy obtained from food. One calorie is the energy that is needed to increase the temperature of 1 g of water by 1 C. Thus one calorie is equivalent to about 4.185 J. On the other hand, a pound is the name of a measurement unit of mass or weight. The pound or international pound, abbreviation "lb", is the mass unit defined as exactly 0.45359237 kilograms or 453.59237 grams.
How many calories per pound?
In today's weight conscious world, the relation between calories and pound is very important. People today are very careful about the calories that they consume. It is important for all to know, how many pounds that is how much weight do they stand to gain while consuming a certain number of calories. To tell the exact calculation, calories per pound = 9.22414105 m2 / s2. That is about 3,500 calories will add up to about 1 pound. This can be applied in two cases. Firstly, one stands to gain one pound on consuming food containing 3,500 calories. On the other hand, one can lose one pound of weight if one was to burn 3,500 calories through exercise. Thus, if one eats 3,500 calories more than his/her body needs; one will put on about 1 pound. And if one uses up 3,500 calories more than one eats, one will lose about 1 pound in weight.
Losing weight by using the calories per pound calculations -
When the daily calorie intake is cut by 500 less than what the body requires, logically the fat stores supply the additional energy requirements. However the energy metabolism is complex and is different between individuals. The fuel used by the body depends on factors like fitness levels, present energy stores, and motivation levels, type of exercise chosen, genetic predisposition and nutritional state. Thus, during a calorie reduction some fuel from fat stores will be used. But the problem is that fat is not the best source of energy for the cells and muscle cells need a constant supply of oxygen for burning fat continuously. Thus though exercising obviously burns many more calories, due to low fitness levels, people fail to supply enough oxygen to enable millions of working cells to continue burning fat for energy. Thus to actually burn one pound of fat, the number of calories to be reduced have to be much more that 3,500.
