This particular article of the series will identify the reasons why weight gain occurs. Doctors call it the physiological changes causing weight gain. The reason of weight gain or loss lies in the amount of energy intake or food consumption we do. The body uses this source to create energy, which it then uses to carry out different biological functions. When excess energy is created, it is reconverted into a physical form in the body stored in fat cells. The fat cells become deposited in different locations of the body, which in turn lead to gain of weight.
In technical terms any amount of weight gain or lost will have two major components. The first component evidently is the increase in fat cells of the body. The second is the increase or decrease of lean body mass, or the muscle tissues.
In some people, there is a parallel increase of both weight and food intake in the body. This is a type of balancing act where adjustment to the new intake levels leads to progressive increase in weight. In other people, the energy expenditure mechanisms may slow down with time. This particular slowing down occurs gradually, so that people report a gradual increase in weight, despite healthy and regular diets with no change in portions. In these particular cases, two situations may cause this weight gain to occur. Either the person reduces his or her physical activity, or there is a reduction in the lean body mass of the body which leads to fat tissue overcompensation, thus leading to weight gain.
The total energy that your body uses up is divided into three activities. The resting energy expenditure is the amount of energy that your body is using while you are in a resting state or a passive state. This takes up almost 70 percent of the total energy your body forms in a day. The active energy expenditure, 20 percent of the total energy expenditure is the energy used up when you do physical activities. Finally the remaining 10 percent is the energy consumed in making new energy. This includes eating, chewing digesting, and absorbing, transforming and storing food energy obtained.
This division clearly shows that while exercise does play an important part, there is an equal role of the body metabolism in its utilization.
The problem with many fad and crash diets is that they may only remove a certain percentage of the fat cells, but not entirely. The rest of the tissue lost is the lean tissue. The lean tissue, such as muscles, ligaments and bones lost take a very long time to heal and restore, which means that the person is likely to suffer from serious side effects of crash diets.
The exercise regime therefore, should include a necessary proportion of weight training exercises targeted towards creating muscle mass and preventing its loss. Some weight loss will occur, however the process can be slowed down.
You must first try to ascertain the kind of body weight changes undergoes. Every person responds differently to energy and weight challenges. There is no one diet solution which will benefit all, due to the fundamental difference in the body metabolism process. When the process of weight gain in a person is identified, personal advice and prescription plan for fitness can be carried out. The physician must surely be consulted if any medical condition exists.
