Fasting is not a new practice or of these times, there has been throughout history, but with other connotations related to religion and culture of many peoples, who implemented it as common practice.

Today, in many cases, the objective has changed fast. Many people do as a means to lose kilos and be thinner. Here is where we will focus, to perform an analysis on whether it is or not healthy, even if there are opinions in favor and against.

There are opinions for defending fasting as a means to lose weight as it would be a way to purify and detoxify the body, especially if you drink only water. These benefits would be achieved, not only because water helps burn fat and cleanse the body, but that fasting would cause the rest of the digestive system. On the other hand, proponents of fasting think that this would be beneficial to remove toxins that may impair the activity of the different cells of the body.

Likewise, there are also opinions against fasting as a means to lose weight, since this would not be the healthiest way of doing it. Why?

During fasting the body is deprived of incorporating foods whose nutrients are used for every cell, tissue and organ to function properly. During fasting are launched a series of adaptive mechanisms that allow each organ works, saving energy. This can be dangerous to health.

When the body does not get the needed nutrients for its operation, it lowers its metabolism, saving energy for the brain and heart function. It is important to have in mind that the brain is glucose dependent. Therefore, if there is little glucose circulating in the blood can cause fainting. This also brings feeling of listlessness, tiredness and fatigue because the glucose circulating in the blood should be used to maintain vital functions.

Also, many people who perform fasting for several hours (especially didn’t have breakfast and no lunch) do not fall below the expected weight or directly the balance does not move. This is because the body adapts to the shortage of food, by reducing the metabolism to a minimum. Thus when the body receives food, rather than increase metabolism, remains low. Why?, Because that energy accumulates for times of food scarcity. This process is called adaptive hyperphagia.

Finally, another of the great dangers of the fasts is incitement to anorexia. The limit is very thin and very subtle. Unfortunately people who suffer from anorexia implement tips or tricks to make a strict fast. These practices, may lead to death.

Fasting is useful for medical purposes and sometimes necessary, but it is controlled. Fasting based on religion and cultures are very personal matters, but the fast (all variants) as a means to lose weight can be dangerous.

So if you’re considering making a diet that includes fasting, do not be swayed by certain promises, consult your physician. Your life is worth more than a few extra kilos.
