Fasting as a means to lose kilos has always been controversial, and no wonder as there are opinions for and against. The lack of food intake throughout the day, results in changes in the body. So if you’re planning to implement as a means to lose weight, it is important to know whether or not healthy.
Fasting is not a novel or practice these times, there has been throughout history, but with other connotations related to religion and culture of many peoples, that implemented it as standard practice.
Today, in many cases, the objective has changed fast. Many people carry as a means to lose kilos and be thinner. Here it is where I will focus, to perform an analysis of whether or not healthy, even if there are opinions for and against.
There are opinions for defending fasting as a means to lose weight, because 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 cause the rest of the digestive tract. On the other hand, proponents of fasting think that this would be beneficial to remove toxins that impair the activity of different cells of the body.
In addition, there are also opinions against making fasting as a means to lose weight, as this would not be the healthiest way to do 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 coping mechanisms, which allow each organ to function, saving energy. This can be dangerous to health.
When the body does not get the nutrients necessary for its operation, low metabolism, saving energy for the brain and heart function. It is important to have in mind that the brain is dependent on glucose. Therefore, if there is little glucose circulating in blood can cause fainting. This also brings about feeling of listlessness, tiredness and fatigue; since the glucose circulating in the blood should be used to maintain vital functions.
Moreover, if fasting is prolonged ketosis (metabolic decompensation caused by the lack of carbohydrates for use as fuel) occurs. While this is a common feature of ketogenic and protein diets, if sustained over time can be dangerous.
Also, many people who perform fasting for several hours (especially not skip breakfast and lunch) not lower the expected weight or directly the balance does not move. This is because the body adapts to food shortages, reducing metabolism to a minimum. Thus when the body receives food, rather than increase metabolism, remains low. Why ?, because it accumulates that energy for times of food scarcity. This process is called adaptive hyperphagia.
Finally, another of the great dangers of fasting is incitement to anorexia. The limit is very fine and very subtle. Unfortunately people who suffer from anorexia implement tips or tricks to make a strict fast. These practices, can lead to death.
Fasting for medical purposes is useful and sometimes necessary, but it is controlled. Fasting based on religion and culture are very personal matters and is not the subject of analysis of this paper; but fasting (in all its variants) as a means to lose weight can be dangerous.
So if you are thinking of 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.
