There is a back-up fuel that all of the tissues in our bodies can use, with two major exceptions. The fuel is a family of chemicals called ketones, and they are released by the breakdown of fat. The two tissues in our bodies that MUST have glucose as fuel are the brain and the heart muscle. All of the other tissues in our body can adapt to deriving their energy from using ketones as fuel. However, the process is a lot like trying to run your Italian sports car on regular gas. It will run, alright, but it won’t run the way Enzo had in mind. Endurance athletes know all about burning ketones for energy. They call the point at which their bodies shift from burning glucose for energy to burning ketones “THE WALL”. The rest of us have our own “WALL” that we encounter when we have a bout of the stomach flu or food poisoning. more

Ketones are fragments of fatty acids that occur in the blood due to the breakdown of the body's fatty acids because there isn't enough insulin in the body. When ketones are present a person MUST get treated for their diabetes immediately. more

Will drinking alcohol affect ketosis? What are ketones? Ketones are a normal and efficient source of fuel and energy for the human body. They are produced by the liver from fatty acids, which result from the breakdown of body fat in response to the absence of glucose/sugar. In a ketogenic diet, such as Atkins ... or diets used for treating epilepsy in children, the tiny amounts of glucose required for some select functions can be met by consuming a minimum amount of carbs - or can be manufactured in the liver from PROTEIN. When your body is producing ketones, and using them for fuel, this is called "ketosis". How will ketosis help me to lose weight? Most reducing diets ... more

Everyone needs fuel to turn into energy. Your body's first choice of fuel is glucose, but if for any reason your body can't use glucose it has an alternative - fat. To use fat as a fuel your body first has to break it down into small pieces; these small pieces are called ketones.

Ketones are produced when the body burns fat for energy or fuel. They are also produced when you lose weight or if there is not enough insulin to help your body use sugar for energy. Without enough insulin, glucose builds up in the blood. Since the body is unable to use glucose for energy, it breaks down fat instead. When this occurs, ketones form in the blood and spill into the urine. These ketones can make you very sick. more

" A: Ketones are a by-product/or waste product when your body burns stored fat for energy. Ketones can be measured in the urine with a visually read strip, and in the blood by using the Precision Xtra® meter. Before I describe various situations in which a person might have ketones, let me provide a simple review of how the body works: • The foods you eat break down into glucose (sugar). Glucose travels in the blood and into your cells. Insulin is a hormone (or "key") that "unlocks the doors of your cells" to allow glucose to enter your cells where it can be turned into energy. So without insulin, glucose wouldn't be able to get into the cells. • Your brain (and the rest of your body) requires glucose to function. When you haven't eaten for a while, or during the night when you're asleep, your liver releases stored glucose to keep you supplied with energy. • If you don't eat for several days, the stored glucose in the liver is depleted, and your body is in a starvation state. In this ...
