After several days of fasting, all cells in the body begin to break down protein. This releases amino acids into the bloodstream, which can be converted into glucose by the liver. Since much of the human body's muscle mass is protein, this phenomenon is responsible for the wasting away of muscle mass seen in starvation.
Starvation ensues when the fat reserves are completely exhausted and protein is the only fuel source available to the body. Thus, after periods of starvation, the loss of body protein affects the function of important organs, and death results, even if there are still fat reserves left.
The syndrome can occur at the beginning of treatment for eating disorders when patients have an increase in calorie intake and can be fatal. It can also occur when someone does not eat for several days at a time usually beginning after 4–5 days with no food. [5] It can also occur after the onset of a severe illness or major surgery.

Catabolysis is the last metabolic resort for the body to keep itself — particularly the nervous system—functional. Protein stores, especially in muscle tissue, provide the amino acids needed for the process. Amino acids are released into the blood and converted in the liver to alpha keto acids.
“There is now a large body of evidence that shows the optimal range for an active healthy adult is anywhere between 1.6g and 2.5g of protein per kilogram of body mass each day,” says Mather.
You might need more protein if you’re pregnant, in which case you should be eating at least 1.1 grams per kilogram of body weight. Elderly people should aim for 1.2 grams per kilogram of body ...
Women between the ages of 20 and 49 were found, on average, to consume about 42 percent of their daily protein at dinner and just 17 percent at breakfast, per a survey conducted by the U.S ...
[3] [14] Stabilization of cardiac muscle cells is done by administering calcium intravenously. [3] Shift of potassium into the cells is done using both insulin and albuterol inhalers. [3] Excretion of potassium from the body is done using either hemodialysis, loop diuretics, or a resin that causes potassium to be excreted in the fecal matter. [3]
