Protein diet to whom? The weight loss pill

I hear a lot about protein diets, how to do well and lose weight quickly.
Just today I read on one of the most famous female forum something like that, but such diets are now so widespread, so much so that it is almost impossible to escape their charm: Scarsdale, Atkins and Zone thrive around by creating a million euro!


We want to take stock of the situation?


These protein diets are based on the principle that, as a nutritious protein plastic (that serve the building of lean body mass and there are a tot a day to replace those parts of the body such as skin, hair and blood cells that are destroyed every day) and having a high satiating power, a power that cuts much carbohydrate and fat, but keeps intact the protein levels or increase them (in some cases even doubling them) will lead to rapid weight loss resulting from the cutting calories while maintaining lean body mass.


All this is healthy?


The RDAs (recommended nutrient intake levels for the Italian population) tell us that the right amount of protein is to be taken to a gram per kilogram of ideal body weight. And in this has already included a safety threshold, which is a quantity more than what it takes the average person, to be sure to include the recommendation also needs higher bands. The average requirement, in fact, is 0.75 g per kg.
This is the amount it takes for the body to replace the whole lean mass that changes every day, not more. A larger quantity of protein, in fact overload the kidney and in the long run, it might even bring it to lose its efficiency.
Another possible negative consequence of some of the most drastic protein diets is the amount, really ridiculous, carbohydrates introduced.
I remind you that our central nervous system, and brain and spinal cord, both our red blood cells, function to glucose, or sugar to.
In case of insufficient intake of sugars, simple or complex they are, the body enters the system in "emergency" and produced from fatty molecules called ketone bodies, which can serve as an alternative fuel for these cells, but in the long run, both systems suffer from a lack of their original nutrients. To have a proper functioning of the two systems the minimum varies from 180 to 200 g of carbohydrates per day!


Another myth food of which I understand is the source "proteins do not make you fat."


AND 'FALSE. Whatever makes you fat nutrient in sufficient numbers!
If my energy expenditure is, say, 2000 kcal and 2500 kcal of meat I swallow, my body turns into fat remaining 500 kcal for the total of 55.55 grams of fat.
not much? Well! is exactly the same amount that would result with 500 kcal of pasta!


In summary: protein diets do lose weight because they are restricted, not because they are protein. On the other hand, for someone that had any kind of renal damage and do not know, could be risky. Pay attention to the proportion of carbohydrates: the minimum is 180 to 200 grams!
