Help me please, biology?

I will post an article, then below a paraghaph written based on the article and information it provided. I need you to see if I got the science on my paragraph correct, and yes I know the grammar is bad, its mu rough draft. The liver stores glucose by converting it to glycogen. It holds perhaps a 12-hour supply of glucose in its glycogen. Once you finish digesting all of the carbohydrates that you last ate, the liver starts converting its stored glycogen back into glucose and releases it to maintain glucose in the blood. Lipolysis also starts breaking down fat in the fat cells and releasing fatty acids into the bloodstream. Tissues that do not need to use glucose for energy (for example, muscle cells) start burning the fatty acids. This reduces the glucose demand so that nerve cells get the glucose. Once the liver runs out of glycogen, the liver converts to a process called gluconeogenesis. Gluconeogenesis turns amino acids into glucose. The liver then begins producing ketone bodies from fatty acids being made available in the blood by lipolysis. Brain and nerve cells convert over from being pure consumers of glucose to partial consumers of ketone bodies for energy. This process is called ketosis -- which is why the Atkins plan is also known as a ketogenic diet. The theory that the Atkins diet is flawed and it has unpleasant side affects. Science behind the theory is as such; when someone consumes carbohydrates, it is broken done into simple sugars called glucose. The liver absorbs these simple sugars, and regulates some to be released in to the blood stream to “maintain glucose in the blood” (health.howstuffworks.com). Fat is then broken down into fatty acids and released “into the bloodstream”( health.howstuffworks.com). Muscle tissue then proceeds to burn the fatty acids. This is the point when the Atkins diet theory steps in. If more carbohydrates are not consumed and the liver runs out of glucose to burn, it instead turns amino acid (the building blocks of muscle) “into glucose” (health.howstuffworks.com). This allows the liver to begin turning fatty acids, the broken down version of fat, into “ketone bodies” (health.howstuffworks.com). blood stream to “maintain glucose in the blood” (health.howstuffworks.com). Fat is then broken down into fatty acids and released “into the bloodstream”( health.howstuffworks.com). Muscle tissue then proceeds to burn the fatty acids. This is the point when the Atkins diet theory steps in. If more carbohydrates are not consumed and the liver runs out of glucose to burn, it instead turns amino acid (the building blocks of muscle) “into glucose” (health.howstuffworks.com). This allows the liver to begin turning fatty acids, the broken down version of fat, into “ketone bodies” (health.howstuffworks.com). The brain, which before was only able to use the energy from gluclose is then able to use the “ketone bodies for energy” (health.howstuffworks.com). However, there are several undesirable effects of this process that is not mentioned. For one, amino acids are not available to build muscle once they are converted to glucose. As a result, he growth of, and performance of muscles is hinderd, which is not only unpleasant but hindering for weight loss as the greater amount of muscle one has the more fat they can burn.

1. Maybe. Your reasoning is sound, but you did not consider what the person is eating. So the body shifts to consumption of fats and protein. Does that mean his body is eventually going to run out of protein?
