People often make a connection between the metabolism and theirweight shifts. Those people who find it a very difficult to gain weight no matterhow much they eat or what type of food they consume are considered to have avery fast metabolism, and the other way around. And although it is true thatthere is a connection between these two things, it does not really function theway the general public usually thinks it does.

What is the metabolism and its functions?

Metabolism includes a number of biochemical processes whichhappen inside the organism, but it is best known to transform food into energy.Every single body process, whether it happens inside the body, such as bloodcirculation, or it happens outside, such as running, and even breathing,requires energy. This energy is gained from the calories that are obtained bythe intake of food and once they are inside the body, they are mixed togetherwith the oxygen, which leads to their conversion to energy.

But of course, notall calories that enter the body are put to such good use. There is aparticular amount of them which is required for this process and it depends onevery person individually, and it is called the basal metabolic rate, or themetabolism. The rest of the calories that enter the body are simply excessiveand may cause weight gain.

Which factors are included in determining the basalmetabolic rate?

First of all, the basal metabolic rate is defined by theperson’s build and body size. The bigger the body, the more calories itrequires to burn, it’s as simple as that. Another important factor is the sex.It is a well-known fact that the weight of men includes more muscles, whilethat of a woman includes more fats. Therefore, men require more calories toburn. The final factor of basal metabolic rate is age. The muscle weight dropssignificantly in older people, and a great deal of it is replaced with fat,which means that the calories are burned considerably slower.

In addition to these factors, calories are also spent ondigestive processes, as well as physical activity.

What is the connection between the metabolism and weightgain?

The metabolism is a completely natural body process and itdoes not cause weight gain, no matter how slow it may function in some people.The excessive weight is gained because the amount of calories which enter theorganism is much above the necessary. For some people it might be somewhatdifficult to set a limit between the calories that the body actually requiresand those that are consumed out of sheer desire or craving. That’s why the bestsolution for those who feel that they need a considerable amount of calories aday is to exercise as regularly as possible, so that they can burn all thatextra fat.
