reversing type 2 diabetes

Yes, diabetes can be reversed!

Because type 2 diabetes is diagnosed based on elevated blood sugar, if your blood sugar remains normal without the use of diabetes-specific medication and you no longer meet the diagnostic criteria, you have successfully reversed your type 2 diabetes.

There are three forms of treatment for type 2 diabetes that have been demonstrated to reverse this disease. Bariatric surgery can sometimes reverse type 2 diabetes, but it is expensive, can have major side effects including death, and often loses its effectiveness after a few years. Very low calorie diets (also called semi-starvation diets) can lead to rapid weight loss and diabetes reversal, but can only be followed for a few months, after which weight maintenance and continued diabetes control are difficult. 

The third treatment is a well-formulated ketogenic diet, which is nutritionally complete and can be followed for years. Forever, really.

The terms “reversed” and “cured” mean very different things. Type 2 diabetes can be “reversed” but not “cured” because the disease will come back if long-term behavior change is not successfully maintained. There are still several points of debate around the term “reversal” -- in particular, how long HbA1c and medication reduction success have to last for the diabetes to be considered reversed. Since diabetes reversal is a relatively new term, there is no universally accepted definition by the scientific community or agencies like the American Diabetes Association or American Medical Association. Thus many medical professionals are still unaware that reversal is even possible.


The definition of reversal

Maintaining an HbA1c below 6.5%, with the elimination of all diabetic medications removed.

Nutritional Ketosis

Nutritional ketosis is a natural metabolic state in which your body adapts to burning fat rather than carbohydrates as its primary fuel.

Ketones are made from fat in the liver, and provide energy to fuel important organs like the brain, heart, and muscles. Ketones also play a newly discovered role to reduce oxidative stress (aka free radicals) and inflammation, both of which are key underlying causes of type 2 diabetes.

Given this dual role of ketones as fuel and metabolic regulator, nutritional ketosis is now understood to be the most effective treatment option for sustainably reversing type 2 diabetes. It is clinically proven to directly reduce blood sugar (as measured by HbA1c), improve insulin sensitivity (as measured by HOMA-IR) and reduce inflammation (as measured by white blood cell count and CRP). Since type 2 diabetes is a disease of high blood sugar, insulin resistance, and inflammation, nutritional ketosis is an effective diabetes reversal tool because it can improve all three.

Entering a state of nutritional ketosis requires changing what you eat. Every food is made up of different components. The major components are carbohydrate, protein, and fat.

Fat is a source of energy that does not raise your blood sugar

Unlike carbs or protein, fat cannot be broken down or converted into glucose efficiently. Furthermore, fat does not require insulin to get into cells to be used for energy, thereby bypassing the problem of insulin resistance. In fact, high insulin levels impair the body’s ability to use fat for fuel, driving it instead into fat cells for storage.

To adapt your metabolism to using fat as your main source of energy, dietary carbohydrates must be reduced to below your unique tolerance level. When you do this, your blood insulin level will come down, giving your body increased ability to burn both the fats you eat and those which you have in storage. For most people, this means switching from the standard recommended high carb, moderate protein, and low fat diet to a high fat, moderate protein, and low carb diet. Fat adaptation does not happen overnight - it can take anywhere from 3 to 6 weeks for most of its benefits to occur, and possibly longer for the full benefits to occur.

Carbohydrates are not essential

You may have heard in the past that you “need” carbs for energy - but basic biochemistry and decades of clinical studies demonstrate otherwise. Carbohydrates are actually the only dietary macronutrient not required by the human body. There are certain essential amino acids that we need from dietary protein and essential fatty acids that we must consume from dietary fats, but no one has yet discovered a carbohydrate molecule that we can’t make within our own bodies. Furthermore, fat is not inferior to glucose as a fuel - your heart and brain actually prefer ketones as a primary fuel source.2

The exception where dietary carbs are necessary is if a person is currently taking diabetes medications associated with the risk for hypoglycemia such as insulin or a sulfonylurea. In this case, dietary carbohydrate reduction has to be closely coordinated with the reduction or withdrawal of these drugs under expert medical supervision.

Protein in moderation

Moderate protein is a key component of nutritional ketosis. While protein is a critical component of any diet to provide the amino acid building blocks required for cellular growth and repair, protein is unable to efficiently provide energy, as the amino acids have to be converted into glucose first. This also means that chronic excessive consumption of protein can raise blood sugar and raise blood insulin levels, which reduces ketone production and impairs weight loss.

Fat is safe in the context of nutritional ketosis

A common concern about following a carbohydrate restricted diet long-term is the eventual need to increase dietary fat intake. For decades now, Americans have been told to restrict fat as a way of not only decreasing the risk for obesity, but also decreasing the risk for cardiovascular disease. This theory has been refuted.3 Consuming high amounts of dietary fat is clinically demonstrated to be safe as long as carbohydrates are restricted. The theory that fat is responsible for heart disease and cholesterol problems has largely been disproven.

Reversing type 2 diabetes with nutritional ketosis

Nutritional ketosis can sustainably reverse type 2 diabetes by directly reducing blood sugar (as measured by HbA1c), improving insulin sensitivity (as measured by HOMA-IR) and reducing inflammation (as measured by white blood cell count and CRP). If you are able to consistently and safely maintain nutritional ketosis (which can be measured with a simple at-home blood test), diabetes reversal becomes much more likely.

Because nutritional ketosis can lead to rapid decreases in blood sugar and blood pressure, The Longevity Formula ensures safety through an outpatient protocol providing intensive nutrition and behavioral counseling, a digital coaching and education platform, and medical provider-guided medication management.

Reductions in average blood sugar

Diabetes is diagnosed by a fasting blood sugar over 126 mg/dL, or an HbA1c greater than or equal to 6.5%. Maintaining nutritional ketosis leads to lower average blood sugars, since eating fewer carbs means less overall sugar entering your bloodstream. Fasting and meal-time blood sugars can rapidly decrease in just the first few days or weeks of carbohydrate restriction. After 2-3 months, you are also likely to see reductions in your HbA1c, which is a measure of your blood sugar control over a 3-month period.
