The rules of a high-protein diet
Given the wide range of dietary recommendations available for a high-protein diet, it is difficult to specify a single, universal definition of this type of diet, as recommended by the Institute of Food and Nutrition. Some sources consider high protein diets to be those where the percentage of energy derived from protein exceeds 25% or where the protein content per kilogram of lean body weight is greater than 1.6 g. However, according to the recommendations of the Institute, the recommended amount of protein consumed during the day by an adult is 0.9 g/kg of body weight.
A list of foods on a high-protein diet
The composition of the high-protein diet should therefore always be preceded by an appropriate nutritional and medical examination. This examination will allow us to assess the patient's health, possible indications or even counter-indications of the planned nutrition intervention. The cause is trivial. The table list on the high protein diet will be completely different for healthy people who are exercising, whose only goal is to reduce fat, maintain or expand fat, and for those who are not physically well fed. Here you can also find the level of high-energy intake of amino acids (which is the highest level of protein intake in the body.
The effects of a high-protein diet
Scientific studies almost unequivocally confirm that dietary protein can have a beneficial effect on weight loss at the same time as cholesterol synthesis (called hunger loss). In other words, it also affects the increase in satiety by increasing the secretion of saturated hormones (GIP glucose-dependent soyotropic peptide and GLP-1 glycagon-like peptide-1) in people who are also dietary dependent on dietary fat loss.
