Ketone bodies that commonly appear in the urine when fats are burned for energy are acetoacetate and beta-hydroxybutyric acid. Acetone is also produced and is expired by the lungs. [1] Normally, the urine should not contain a noticeable concentration of ketones to give a positive reading.
Physiological ketosis is the non-pathological (normal functioning) elevation of ketone bodies that can result from any state of increased fatty acid oxidation including fasting, prolonged exercise, or very low-carbohydrate diets such as the ketogenic diet. [5] In physiological ketosis, serum ketone levels generally remain below 3 mM. [1]
The ketogenic diet results in adaptive changes to brain energy metabolism that increase the energy reserves; ketone bodies are a more efficient fuel than glucose, and the number of mitochondria is increased. This may help the neurons to remain stable in the face of increased energy demand during a seizure, and may confer a neuroprotective ...
The result is a rate of ketone production higher than the rate of ketone disposal, and a decrease in blood pH. [12] In extreme cases the resulting acetone can be detected in the patient's breath as a faint, sweet odor. There are some health benefits to ketone bodies and ketogenesis as well.
Their excretion in urine is very low and undetectable by routine urine tests (Rothera's test). [18] When the rate of synthesis of ketone bodies exceeds the rate of utilization, their concentration in blood increases; this is known as ketonemia. This is followed by ketonuria – excretion of ketone bodies in urine. The overall picture of ...
Suzanne Ryan weighed nearly 300 pounds when she decided to make a change. Ryan, a mom from the San Francisco area, started following the ketogenic diet, a diet focused on foods high in fat and low ...
Positive result on a Ketostix test strip, which is specialized for measuring ketones. Ketone bodies are products of fat breakdown. When the body relies on fats, rather than carbohydrates, as its main energy source, increased levels of ketones occur in the blood and urine. The presence of detectable levels of ketones in the urine is called ...
