RETURN TO BLOG 29th December 2019 By the LiMe Program Medical Research Team Why Low Carb/High Fat and Keto Diets Only Make Type 2 Diabetes Worse Long Term….. But Still Have Some Use. These days, people living with type 2 diabetes are bombarded with an array of diet options claiming to reverse diabetes or put it into remission. The common theme is to minimise or avoid all carbs. Carbohydrates are wrongly demonised as the enemy of diabetics and even blamed for causing diabetes. While it is true that refined and processed carbs such as sugary soft drinks, white bread, cakes and junk foods like doughnuts, pastries and most breakfast cereals, should be avoided, to generalise and include healthy, complex carbohydrates is a huge mistake. Complex carbs such as whole grains, fruits and vegetables should be the long-term mainstay of a healthy diet for everyone; whether living with diabetes or not. The Health Canada food plate shows ¾ of the plate being carbohydrate rich foods. These low carb diets mistakenly focus on virtually eliminating carbs and relying mainly on fat and protein as the macro- nutrients. They range from unsustainable very low calorie diets to the ‘craze’ diets such as Paleo and Ketogenic (Keto). Mostly promoted by celebrity chefs with no understanding of nutrition or medical doctors with no training in nutrition, who think the title ‘doctor’ carries unquestionable authority, these diets become well marketed fads that don’t get nearly enough scrutiny and cause long term harm. The Keto diet is probably the most popular diet going around when it comes to diabetes reversal diets. Does it work? The answer is ‘yes’ and ‘no’. In the short term, the keto diet has some value - it often brings blood glucose numbers back into the normal range, if measured by a fasting blood sugar test or HbA1c test, so it appears to work. However, in the long term it does not and is potentially a life-threatening disaster. A simple pathology test, known as the Oral Glucose Tolerance Test (OGTT), which is the gold standard for diagnosing diabetes, will confirm how ineffective it really is both in the long and short term. Very simplistically, the reason it seems to work in the short term is to do with how the body responds to eating carbs. By avoiding carbs, which the body converts into blood glucose, blood glucose levels stay lower and may even seem normal. Protein rich and high fat foods don’t cause the same blood glucose elevation as carbs. Avoiding or severely restricting healthy, complex carbs will eventually worsen diabetes and cause many other health problems. The false logic of keto diets Type 2 diabetes is not a condition caused by excess carbohydrates or carbohydrate intolerance, as is claimed by keto diet marketers. Their false logic is that because carbohydrates break down into sugars in the blood and because diabetes is a condition of high blood sugars, avoiding carbs reduces blood sugars and fixes diabetes. It appears logical at first glance. The only problem is, that although it is not immediately obvious or generally known, diabetes is mainly caused by excess fat, not excess carbs or sugars. Most cases of type 2 diabetes are a condition of insulin resistance, where there is more than enough insulin being produced but it is ineffective. Insulin resistance is caused by a build up of fats inside the cells. The medical term is intramyocellular lipids. These fats ‘clog up’ the cells’ insulin receptors and when that happens, insulin signalling is disrupted, insulin can’t do its job of opening the ‘doors’ to the cells and the glucose in the blood can’t enter the cells, where it is needed for energy. The glucose remains in the blood, causing high glucose levels, which is known as diabetes. Reversing insulin resistance and restoring insulin sensitivity is the key to reversing type 2 diabetes permanently. The best way to do that is to clear out the fats inside the cells so that when carbs are eaten, the glucose can quickly enter the cells and blood glucose levels remain normal because insulin is doing its job in an environment of high insulin sensitivity Over time, low carb/high fat, keto style diets gradually worsen diabetes by worsening insulin resistance. Their high fat content increases the levels of fats inside the cells and the insulin resistance increases as insulin effectiveness decreases. Eating healthy complex carbs becomes more and more difficult the longer this unhealthy state continues. Healthy, complex carbs, which are recommended as the mainstay of a long term way of eating are essential for long term good health. The longer healthy carbs are avoided, the more the risks of chronic diseases like cardio vascular disease, vascular dementia, arthritis, cancers and auto-immune diseases increases. Credible, science based agencies such as Health Canada specifically say to include plenty of healthy, complex carbohydrates for long term health reasons. Proof that high fat/low carb, keto diets fail A simple way to show how ineffective high fat/keto style diets really are at reversing insulin resistance and in turn reversing diabetes, is to do an Oral Glucose Tolerance Test (OGTT). The OGTT is like a stress test for insulin effectiveness. It places the insulin process under a load and shows how it is performing. It is the gold standard for diagnosing diabetes. Usually done over 2 or 4 hours at a pathology centre, it involves drinking 75grams of a glucose solution and taking insulin and blood glucose readings at regular intervals. If insulin resistance is high, which it will be by following a high fat, keto style diet, blood glucose levels will remain high for a longer period and if pancreatic function is still high, a large amount of insulin will be produced as the body attempts to reduce the blood glucose to normal levels. Keto based programs never use this test to measure their effectiveness because they will show insulin resistance is high and diabetes has not been reversed. ‘Normal’ blood glucose levels are not the same as being non-diabetic. A keto style diet can make other pathology test numbers look good while hiding the underlying and worsening problem of insulin resistance. HbA1c and other tests that measure blood glucose can be misleading and not detect insulin resistance if following a keto style diet. The OGTT is a very valuable test because it shows how effective insulin is, which is the key to reversing diabetes long term. On the other hand, a low fat, high complex carbohydrate eating style has been shown to clear the fats inside the cells, which in turn restores insulin function and lowers blood glucose levels because the glucose can now enter the cells instead of remaining in the bloodstream and causing diabetes. It forms the basis of long term eating guides such as those promoted by Health Canada. No credible agency suggests eating a keto style diet. The only drawback of a low fat, high complex carb diet is that it can cause blood glucose levels to spike when there is a state of insulin resistance, which is nearly always the case with type 2 diabetes. How to get the short term benefits of keto AND the long term benefits of high complex carbs In another blog article, we introduce the LiMe Program’s solution to this problem using the Karbeto protocol.

Refund Policy We will refund all coaching fees if a client does not achieve improvement in their type 2 diabetes as measured by the 3 diabetes blood tests, provided the agreed coaching program is followed and is verified.
Disclaimer & Results To meet our definition of genuine type 2 diabetes reversal, a number of criteria must be met to achieve non- diabetic range blood sugar levels. These include; (a) not requiring any diabetes medications or insulin to be taken. (b) achieving normal range blood sugar levels as measured by 3 blood tests; HbA1c test, the 2 hour glucose tolerance test (GTT) and a fasting blood sugar test. It is only possible to reverse type 2 diabetes. Type 1 diabetes and type 1.5 (LADA) diabetes cannot be reversed and will always require insulin. A small proportion of type 2 diabetes cannot be reversed when insulin production has become insufficient. Results achieved can vary between individuals and depend on many factors, such as degree of compliance with a coaching program, pre-existing conditions, severity of existing conditions and the rate a coaching program is implemented.
