Protein or hyperproteic diets are characterized by protein-rich foods, such as fermented dairy products, meat, fish, sausages and even nutritional supplements with a high protein content. Proteins are supposed to modulate metabolism so that the body needs a greater amount of energy to digest food, causing a rapid sensation of satiety and consequent decrease in appetite.
In addition, if carbohydrates (bread, pasta, sugars, potatoes, rice or other cereals) are eliminated, the body is forced to resort to fat accumulated in the body to obtain the energy required for digestion, Which causes you to lose weight. These diets also limit the consumption of vegetables, vegetables and fruit.
Protein diets that target rapid weight loss, including some very famous ones such as Atkins or Dukan, are a subject of continuing controversy and are generally considered to be miracle diets by nutrition experts and endocrinologists, Since although it can effectively lose weight quickly, they carry important health risks and once they are abandoned, the weight that has been lost is recovered.
Risks of Protein Diets
The consequences for the organism of the protein diets are multiple and some of them serious. Symptoms such as nausea, vomiting, loss of appetite, fatigue, constipation, malaise, etc. usually appear at the beginning. However, there are others that should be considered as worrying:
Loss of muscle mass: the absence of carbohydrates leads to the implementation of a series of mechanisms to obtain energy by sequestering the glucose present in muscle tissue.
Formation of ketone bodies (ketosis): the body must resort to the fats accumulated in the body to decompose and use them as a source of energy. In addition to all the aforementioned effects, ketosis has been shown to produce metabolic acidosis and, as a consequence, alterations of the nervous system and the contractibility of the fibers of the cardiac muscle can occur, favoring the appearance of arrhythmias. Cases of sudden death and ketone coma have been reported for this cause.
Alterations in blood analytics: given their high fat content, hyperproteins diets increase levels of uric acid, cholesterol and triglycerides.
Kidney and liver overload: the kidneys should make an extra effort to remove excess protein through the kidneys, and the liver to be able to metabolize nutrients, which may aggravate existing pathologies (renal failure) or The appearance of others.
Deficiency diseases: the alterations of the metabolism that cause this type of diets makes that the nutrients can not be assimilated correctly. Added to this is the fact that fruits, vegetables, legumes and cereals are hardly ingested, pathologies due to deficiency states of certain nutrients can occur.
Therefore, protein diets are only recommended for a few days and, in any case, always under medical supervision.
