Ketosis

Not to be confused with Ketoacidosis. Ketosis is a metabolic state in which some of the body's energy supply comes from ketone bodies in the blood, in contrast to a state of glycolysis in which blood glucose provides energy. Ketosis is a result of metabolizing fat to provide energy. Ketosis is a nutritional process characterised by serum concentrations of ketone bodies over 0.5 mM, with low and stable levels of insulin and blood glucose.[1][2] It is almost always generalized with hyperketonemia, that is, an elevated level of ketone bodies in the blood throughout the body. Ketone bodies are formed by ketogenesis when liver glycogen stores are depleted (or from metabolising medium-chain triglycerides[3]). The main ketone bodies used for energy are acetoacetate and β-hydroxybutyrate,[4] and the levels of ketone bodies are regulated mainly by insulin and glucagon.[5] Most cells in the body can use both glucose and ketone bodies for fuel, and during ketosis, free fatty acids and glucose synthesis (gluconeogenesis) fuel the remainder. Longer-term ketosis may result from fasting or staying on a low-carbohydrate diet (ketogenic diet), and deliberately induced ketosis serves as a medical i Continue reading >>

    Whilst at my clinic visit today, they took a urine sample to test for ketones. There were none and I was pronounced 'Normal'.
    The consultant was very pleased by this - explaining that if they'd found ketones it would be a problem - not good at all.
    Isn't Ketosis a good way of reducing weight? or is it very very bad (as was suggested today).

    Ketones can be a sign of ketoacidosis, which is very, very bad.
    They can also be a sign of ketosis, which is very, very, good for weight loss, and not at all harmful.
    Consultants that confuse ketosis and ketoacidosis are very, very, bad, and IMHO are not fit to practice medicine.

    My Endo has always insisted both are harmful.

    The ketogenic diet is a popular, effective way to lose weight and improve health. When followed correctly, this low-carb, high-fat diet will raise blood ketone levels. These provide a new fuel source for your cells, and cause most of the unique health benefits of this diet (1, 2, 3). On a ketogenic diet, your body undergoes many biological adaptions, including a reduction in insulin and increased fat breakdown. When this happens, your liver start ...

    Print Overview Diabetic ketoacidosis is a serious complication of diabetes that occurs when your body produces high levels of blood acids called ketones. The condition develops when your body can't produce enough insulin. Insulin normally plays a key role in helping sugar (glucose) — a major source of energy for your muscles and other tissues — enter your cells. Without enough insulin, your body begins to break down fat as fuel. This process ...

    Diabetic ketoacidosis (DKA) often gives plenty of warning before it happens, but it can also occur with little warning. If you regularly check your blood glucose several times during the day, you won’t miss the most important warning signs: high blood glucose and ketones in your urine. Test your urine for ketones whenever your blood glucose is over 300 mg/dl or you feel ill. Signs of DKA include the following: High blood glucose above 240 mg/dl ...

    I kid you not. I was a junior doctor at a busy London A&E department, where queues were piling up of people waiting to be seen. There was an array of the usual presentations, including the breathless asthmatic, a couple of chest pains, renal colics, nausea and vomiting and so on as expected. What I never expected, was this young woman who had waited almost 3 hours to be seen, who presented with what was essentially a papercut. She was wearing sma ...

    Diabetes can be hard to manage, but not properly controlling the disease can have dangerous and potentially deadly consequences. Ketoacidosis is one of them. This condition happens in people who don’t have enough insulin in their body, perhaps because they have not taken some of their insulin shots. The U.S. National Library of Medicine explains that when insulin is lacking, and the body cannot use ingested sugar as a fuel source, it starts to ...
