A great post from our friend Canuck.

This is a great post made on the forum diabetes.co.uk over the weekend. It was deleted by the mods, why ?

Ketosis occurs when your intake of carbs drops below the point where there is enough glucose coming in to fuel your brain. Your brain cannot burn fuels other than glucose or ketones. When your carb intake drops below that point your liver starts to make ketones from fat. Your brain can get 75% of its energy from ketones. The remaining 25% can come from glucose which is also produced in the liver (from protein). The muscles will burn fat or ketones. There are actually very few tissues that must have glucose. These include the renal cortex, red blood cells and lens of the eye. All their needs can be supplied by the liver. This is why there is actually a zero requirement for dietary carbohydrates. Most people need to get below 100 gm of carbs per day to achieve ketosis. For people with severe insulin resistance, the carbs would need to be much lower to achieve normal blood sugars and to get off the meds. I avoid meds by eating less than 50 gms and usually well below that.

Unlike low fat diets, low-carb is very effective at burning off the fat around the middle. Properly done it will also spare muscle loss and may even cause muscle growth along with fat loss. For type 2 diabetics, I recommend the most recent Atkins book which was authored by three scientists who do research on ketogenic diets (Westman, Phinney and Volek). I get the best results by staying on the induction phase of the diet indefinitely. I have done this for over 8 years. I asked the authors why they didn't recommend this in the book. They said that they actually had written a chapter on this but that the publisher removed it for fear it might confuse people. Phinney and Volek have recently written a guide for physicians on how to properly administer a low-carb diet. It will be published as an e-book and will be available soon via Amazon.

Thank you very much Dr Jay. That explains why I need to be on a virtually zero-carb diet to lose weight. Being on 'zero' carb is actually helping a long-standing issue my body is struggling with too (most other things have already healed on low-carb). It's only been a week so far, but the signs are good. Barry Groves has a good article on proteolytic bacteria and how too many carbs in the diet can upset the balance in the gut and create inflammation. Yup. Been there.
