Proteins and Carbohydrates

their staple meal, as if they were the fundamental macronutrient of the diet.


In reality, proteins play a fundamental role in the reconstruction of tissues, while the real main fuel of our body always remains the carbohydrate.

to a car, we could imagine proteins as spare parts or worn parts of the car (for example the tires to be replaced, the filter to be changed, etc.) while carbohydrates as a kind of gasoline. We know very well that a "car without petrol could not move, fortunately for the human body it does not work in the same way, without carbohydrates, it is able to continue to carry out its cellular functions using proteins; this will, however, lead to a hypoglucidic or low diet. carb (Low Carbohydrate Content) which will lead to the appearance of ketosis, a "metabolic alteration characterized by" the accumulation of ketone bodies, secondary to the reduction of blood sugar which, in prolonged cases, will lead to unpleasant complications.

So why do different athletes or simple fitness enthusiasts resort to these high-protein diets more and more often?

The answer would seem to fall on endocrinological principles (Hormonal Factors), in fact a high-protein and drastically hypoglucidal diet would allow, in combination with an adequate physical training plan, to obtain a fast and consistent increase in muscle mass, the theoretical assumption is represented by a true and own axiom: the accumulation of proteins in the muscles in the form of myofilaments is due more to the high-protein diet than to the stimulus produced by physical exercise. This axiom would find confirmation in two of these points:

  • Unassailable evidence: the functions performed by proteins and the eight essential amino acids have a critical value for the organism; it is therefore unthinkable that the organism wastes these macromolecules without providing for the formation of an adequate deposit. Filiform muscles would be sufficient to support normal vital functions, the existence of such an evident surplus cannot but be interpreted in the sense of a reserve deposit
  • Hormonal factors: protein caloric hypernutrition minimizes testosterone production and also increases urinary excretion; high-protein meals increased protein storage synthesis, especially if most of the protein content is taken in a single meal; furthermore, the anabolic effect of growth hormone (GH) seems to be given to the suppression of catabolism rather than to the true increase in protein synthesis. Insulin plays an important role in ensuring a high level of protein deposition in the muscle which it performs more effectively at moderate levels. Hence the need to limit the intake of carbohydrates (or carbohydrates) that are harmful for the purpose of deposition protein.

Therefore, an "almost totally protein and high calorie diet creates hormonal situations favorable to the deposition of proteins in the muscles in the form of myofilaments, making them substantially larger (hypertrophic). But what are the possible consequences of such a diet?

- even if, in healthy subjects, it is difficult to demonstrate real measurable damage. Another important element appears the risk of alteration of the intestinal microflora whose correct development is closely related to the presence in the diet of carbohydrates, fiber, vitamins and mineral salts, nutrients eliminated in high-protein diets. The last but not least important aspect is the consequence of extracellular dehydration always induced by too many proteins.

Body Building

Many add to this already dire situation periods of 5-6 days of high-gloss diet during intense workouts, followed by about 10 days of high-protein diet during muscle recovery and light workouts. In fact, as previously mentioned, small amounts of insulin (High Protein Diets) guarantee a higher protein synthesis than that promoted by an excess of the hormone (Hyperglucidic Diets). Do not forget that the rapid recovery of muscle mass after a period of food shortage is a mechanism defense biological (Emergency) selected over millennia of evolution not a physiological system to be tapped into in an unlimited way.

Note: for those who really do not want to raise the calorie intake of carbohydrates and decrease the protein intake, it is recommended to drink a lot of water, in doing so it is possible to slightly reduce kidney stress.
