Macronutrients levels (hydrates, fats and proteins) are proportionally reduced compared to a typical balanced diet. This lowers the amount of calories consumed daily, resulting in weight loss.
Protein intake in this case is insufficient to maintain muscle mass. Weight is lost, including excess fat, but a high percentage of muscle mass is also lost.
Loss of muscle mass will cause the Basal Metabolism to descend after finishing the diet; with the consequence that our body will need less energy (calories) than when we started the diet. Once we return to our usual diet – and especially if we have not changed our eating habits in favor of a balanced diet – this can cause an increase in lost weight, due to this decrease in Basal Metabolism.
*Notes: Basal metabolism is the minimum value of energy necessary for our body to survive. This minimum energy is used to carry out essential metabolic functions, such as breathing. The metabolic rate decreases with age and with the loss of muscle mass. Increasing muscle mass is the only thing that can increase this rate.
The KETO PROTEIN diet is not a high-protein diet, nor is it a low-carb diet.
High protein diets excessively increase protein intake; they can overload your metabolism. Low-calorie diets reduce the intake of fats, sugars, and proteins, which makes it difficult for the body to maintain its vital functions and causes loss of muscle mass.
The KETO Protein Diet reduces fat and sugar intake, while providing the protein necessary for the functioning of the body; allowing weight loss to take place at the expense of fat mass, all the while maintaining muscle mass.
Carb consumption (bread, pasta, rice, potatoes, etc.) is reduced in favor of foods rich in proteins, but the consumption of fats is not reduced.
In addition, typical protein-rich foods are rich in saturated fat. This causes an increase in cholesterol and triglycerides (with the consequent cardiovascular risk). In this type of diet there is also an increase in uric acid (with the consequent risk of problems such as kidney stones and gout [uric acid crystals in the joints])
In short, it is a totally inadvisable diet.
