Diet itself can produce normal urine ketosis, in some cases. (2) Vomiting can't stay in the stomach because of what you eat, because usually when the total amount of fatty acids exceeds the total amount of glucose by more than one and a half times, too many ketone bodies will be produced and excreted from the urine. (3) In this case, overwork and manual labor consume too much glucose. (4) When you have a high fever, the consumption of glucose in the body increases, that is, the source of glucose decreases, and ketone bodies can also appear in urine, which reduces the source of glucose in the body, so the decomposition of fat is accelerated and excessive ketone bodies are produced, while foods containing carbohydrates are reduced and the decomposition of fat is accelerated. (5) Eating foods with too much fat Because of eating foods with too much fat, the supply of glucose is temporarily lacking, so the decomposition of fat is accelerated, so the decomposition of fat is accelerated, and ketone bodies appear in urine. (1) When people are hungry, they lack glucose sources, and sometimes ketone bodies appear.
