Nowadays the word "metabolism" is so wide-spread and we can hear it very often, in a wide variety of contexts. Often, a slow metabolism is ‘accused’ that a person cannot lose extra kilos and continues to gain weight, despite attempts to get rid of it. Therefore, there is a rather widespread idea that fast metabolism is preferable to slow metabolism. However, the fact that a person has a fast metabolism does not always mean that he or she has good health. In fact, it can even speed up aging process.
In a nutshell, it is generally accepted that a fast metabolism is very good for health and fit appearance, and a slow metabolism is bad and can lead to overweight. However, in fact, such opinion is fundamentally wrong. Let’s see why.
According to the definition, ”metabolism” is a set of chemical reactions that take place in the body and supports life in it. Metabolism impacts all cellular functions and plays a fundamental role in biology. Life is maintained in a human body through energy supply of muscles mechanical work, production of heat, digestion of food, synthesis of necessary substances and so on. All these, and hundreds of thousands of other chemical reactions in the body, should be carried out exactly as it is provided by nature. No faster and no slower than the set speed.
When a doctor or a scientist says that metabolism is ‘bad’, it does not mean a slow rate of chemical reactions (as we are supposed to think), but only shows that some reactions go wrong. For example, under certain conditions, cells lose sensitivity to insulin and, as a consequence, the ability to take glucose from the blood (that can be a symptom of diabetes mellitus). As a result, instead of glucose, fat begins to split. However, during this process, the synthesis of fat is much faster than its oxidation. This mechanism can lead to various negative and serious health problems – from obesity to cancer.
Thus, in fact, when we mean a health disorder, it’s not because of “slow metabolism”, but of “bad or pathometabolism”, some of such health disorders can be treated by proper diet and exercise.
Fast and slow types of metabolism are processes that have nothing to do with the situation described above. Speaking about the metabolic rate, we can only talk about the rate of use of those substances that enter the body. And nothing more. It is obvious that the faster the certain substances in the body are consumed, the faster the body will need to replete them. From this perspective, it seems strange that some people want to boost the metabolism. Their logic sounds like this: “I spend 3000 calories every day and consume 3000 calories. If I speed up my metabolism up to 4000 calories, I can eat 1000 calories more!” But it is nonsense. Isn’t it easier just to eat less?
Forget about slow or fast metabolism and attempts to boost it (as we are accustomed to by numerous publications in magazines and Internet). Remember that the metabolism should be neither fast nor slow, but normal, that means healthy, without any disorders.
For example, if the body, instead of oxidizing glucose, has restructured to use fats, and sends glucose into the liver to process, then the situation needs to be changed urgently. But not in order to speed up your metabolism and consume more food, but to avoid serious pathological changes in the body – obesity, atherosclerosis, impotence and heart attack.
And as for the desire to lose weight, our advice is simple – just eat less…
