Consequences of a diet with carbohidrates restriction, or a protein diet

When a deficiency of carbohydrate (which is the main source of energy) occurs in the body, there will certainly be a replacement. However, this substitution is not simple and much less without risks. One of the things that will happen is the use of stored fat as a source for energy.

Up to this point, it seems to make sense to remove carbohydrate from a diet, right? But what happens to the body and when it happens is not good.

Let’s understand. When we have a correct diet, ie, with the ideal amounts of carbohydrates, we use them mainly as a source of energy and also to make lipolysis, that’s right, fat breakdown. Yes, we are building and breaking our fat all the time.

If carbohydrates are removed from our diet we will not have the ideal energy source and, consequently, the body seeks to use the reserves we have and, yet, under these circumstances, now it will not have that substance that aids the breakdown of fat, carbohydrate. Here is the problem. Since there is no carbohydrate to be used, the body will use protein and a lot of muscle protein.

We found the problem. In addition to the protein breakdown and loss of lean body mass, the production of two substances resulting from protein breakdown will occur, and the two are toxic. One will overload the liver and kidneys to be eliminated and other will cause bad breath and behavioral change.

The individual will be extremely irritated. Another point to be noted is that with the increase of the use of fat, there will be more fat circulating in the blood stream.

So the results of this type of diet are: bad breath, irritation, decreased toughness of muscles, liver and kidney overload, and, yes, fat loss.
