Starvation is a severe deficiency in caloric energy intake, below the level needed to maintain an organism's life. It is the most extreme form of malnutrition. In humans, prolonged starvation can cause permanent organ damage [1] and eventually, death. The term inanition [2] refers to the symptoms and effects of starvation.
Starvation response in animals (including humans) is a set of adaptive biochemical and physiological changes, triggered by lack of food or extreme weight loss, in which the body seeks to conserve energy by reducing metabolic rate and/or non-resting energy expenditure to prolong survival and preserve body fat and lean mass.
Protein toxicity is the effect of the buildup of protein metabolic waste compounds, like urea, uric acid, ammonia, and creatinine.Protein toxicity has many causes, including urea cycle disorders, genetic mutations, excessive protein intake, and insufficient kidney function, such as chronic kidney disease and acute kidney injury.

This timing of protein use is contested: that at first the body practices autophagy to source amino acids rather than being simultaneously used with ...
One can still stay alive while the body breaks down the fatty tissue (hence people wasting away from starvation). The person may, during catabolysis, have large amounts of lipids , proteins , and amino acids in the bloodstream, due to the muscle fibers and adipose tissues being broken down and sent to the nervous system and brain .
