The plan begins with the calculation of protein needs of a person - determined, 0.6 grams of protein per pound of lean body mass for a moderately active person (more for persons who are more active and less for those who are less active). Then it is followed by the calculation of lean body mass with standardized tables, height, waist and abdomen measurements with women and weight, wrist and waist measurements in men.
Dieters are recommended to the minimal amounts of proteins on the basis of the above calculations, but said that they eat more when they are hungry. Carbohydrates are limited to 30 or 50 grams daily, which is the whole day.
Scientific analysis
The main objection to the Protein Power diet plan is the calculation of protein needs. In research on the protein requirements, there is no valid evidence found, the activity as a basis for protein intake. In the absence of glucose, the muscles use fat for energy, and do not need more or less protein for the activity. If protein is "broken" to stir up, the actual molecules, while the connections between them are broken. To the protein molecules only energy required to reform the chemical bonds.
Another consideration is that a person's protein requirements depend on what other nutrients are consumed as energy sources. If carbohydrates are included in the diet, more protein is needed to be converted to glucose as fuel for the brain.
On the basis of scientific studies, the carbohydrate-protein-Power of 30 or 50 grams a day are not high enough to prevent ongoing ketosis for most people, especially those who are to lose weight, or on a maintenance diet .
90 grams of carbohydrates per day is sufficient to inhibit ketosis in patients on a low carbohydrate diet. It is a legitimate concern that the ongoing ketosis can take some risks in the long run. With the help of Protein Power diet for a limited time for the weight loss should not cause any major problems, but the design is not sufficient for long-term use.
