The second of these is ketones. Your body releases ketones when you are burning fat/muscle rather than available carbs in your bloodstream. The possibility of this happening was actually brought to my attention by Scott over at Scott’s Diabetes Journal, and I was so intrigued by it I had to test it out on myself! Sure enough, after an especially long and hard workout, I had quite a bit of ketones! I’m actually amazed that this isn’t something my doctor hasn’t brought up as it sure drives home what I try to enforce anyhow when working out: DRINK MORE WATER! The presence of ketones will make you resistant to insulin, helping to feed that high you may already be heading for because of unabsorbed carbs! Hopefully this will help to reduce those ketones in the blood stream. Do not let yourself get dehydrated during a workout; the highs are rough to recover from! |
Hi Paul,
Apparently the subject of ketosis, especially for diabetics, is somewhat controversial.
I'm going to continue to research the subject, but here's an article that's 180 degrees from the opinion that you quoted.
The Insulin-Smart Life Extension Program
Here's an excerpt:
Quote:
Dietary Ketosis Accelerates Results
Some life extension experts are taking the low glycemic approach to an extreme -- with excellent results. Very low carbohydrate diets such as the well-known Atkins diet produce a state of benign dietary ketosis (BDK), which has been found to have an exceptionally rejuvenating effect on the biological terrain. The consumption of about thirty or fewer carbohydrates a day may promote a myriad of advantages, including longevity and weight loss, and the reversal many of the conditions associated with aging. The BDK diet has all the benefits of the low glycemic diet, and also offsets cravings, discourages yeast infections (candida), balances mood disorders, and reverses heart disease. (4)
Being in ketosis is the quickest, safest, and healthiest way to control hyperinsulinism and burn off excess body fat. The key to its effectiveness is a shift in the body's fuel supply. Several studies have shown that as carbohydrate intake is sufficiently lowered, the metabolism shifts from a glucose-based energy supply to one that utilizes the body's own fat. This mechanism, called lipolysis, occurs during sleep, fasting, and when insulin levels are low. (6)
After two days without carbohydrates, the absence of glucose induces lower insulin levels which cause the desirable metabolic shift. As lipolysis begins, the body enters into ketosis. First, fats (triglycerides) are split into glycerol and free fatty acids. These are then broken down into simple compounds called ketone bodies, which in turn are used as fuel by the brain and muscle.
The degree of fat utilization can be inferred by measuring blood or urine levels of ketones. The level of ketones in the urine can be measured at home with Ketostix®, which are available over-the-counter (OTC) at any pharmacy. A slight state of ketosis is reflected by a light peach color. The more ketones that are released, the deeper the state of ketosis, and the darker the shade of the stick. Purple, which reflects the deepest state of ketosis, also indicates that maximum fat loss is occurring. However since insufficient water intake can cause concentrated urine (and the false impression of elevated ketones), it is important to drink plenty of water when following this diet.
The basis of the BDK diet is proteins, fats and very low carbohydrate-containing foods, with meals consisting of eggs, fish, fowl, meat, cheese, dairy cream, non-starchy vegetables, herbs, and spices. Breakfast might consist of an egg and cheese omelette with a side of bacon; lunch, a tuna salad with greens and creamy dressing; and for dinner, steak and lobster drenched with butter and a side of sauteed broccoli. It is surprisingly simple to follow, and is satisfying as well. (4)

The above article seems to be more in line with many, perhaps most, of the other Low-Carber forum members.

, but I walk a lot and if my BG would go up each time I walk, I would get extremely worried as to why, even if it is just a 10 point rise.
