How to reverse your type 2 diabetes

Do you have type 2 diabetes, or are you at risk for diabetes? If so, then you’ve come to the right place.

This guide gives you an overview of what you need to know about treating and reversing type 2 diabetes. Our other guides can teach you more about the symptoms of diabetes, as well as provide specific information about type 2 diabetes and type 1 diabetes.

Many people with diabetes or prediabetes have improved their health with dietary changes. You can too! Making these changes may allow you to reduce or eliminate diabetes medication, and help you lose weight as well.

Keep reading to see if this could work for you!

1. What is diabetes?

  1. Simply put, diabetes is a disorder of blood sugar (glucose) and insulin.  In diabetes, something is wrong with the way a person makes and/or uses insulin, a pancreatic hormone that lowers blood sugar by moving it out of the bloodstream and into the body’s cells.

    Type 1 diabetes results when, for autoimmune or other rare reasons, the pancreas becomes damaged and fails to produce insulin. This form of diabetes is most often diagnosed in childhood but can occur in adults.

    In type 2 diabetes, there are defects in both the production of insulin by the pancreas (insulin deficiency) and the use of insulin by the body (insulin resistance). When damage to the pancreas’ insulin-producing cells progresses to the point where the pancreas can no longer spontaneously release enough insulin to overcome the body’s resistance to it, blood sugar levels rise.

    Excess glucose in the blood is a problem because it can damage blood vessels. What’s more, the body’s tissues can’t effectively use glucose for energy because too much of it stays in the bloodstream instead of entering the cells.

    It is important to recognize that high glucose levels are a consequence of an underlying process that has been going on for years before blood sugar becomes high.

    The good news is that diet and exercise can help decrease insulin resistance and its associated weight gain, which may help prevent or even reverse diabetes.

    Early on the road to developing high blood sugar and getting diagnosed with type 2 diabetes, an insulin-resistant person usually has too much insulin in the blood. This is due to the pancreas reacting to the death and/or dysfunction of its insulin-producing beta cells.

    Essentially, the pancreas realizes that it has two problems: its overall ability to make insulin is getting worse, and the insulin that it is able to make isn’t working very well. So, the pancreas cranks out more insulin to flood the body’s insulin receptors and overcome the resistance. This works to keep blood sugars normal, until so much beta cell function is lost that the pancreas can no longer crank out excess insulin

    Other than its implications for blood glucose and progression of type 2 diabetes, why is it bad to have high insulin levels?

    Insulin increases the storage of fat and reduces the body’s ability to use fat for fuel. This can lead to weight gain, which plays an integral role in the development and worsening of insulin resistance. Left unchecked, you can see how this will lead to a vicious cycle: insulin resistance leads to high insulin levels, which make it easier to gain weight by accumulating fat, which increases insulin resistance, which leads to high insulin levels, which leads to more weight gain, and so on goes the cycle.

Type 2 diabetes

  1. Type 2 diabetes is by far the most common form of diabetes, accounting for over 90% of all cases.

    Type 2 diabetes begins when an individual makes more insulin than the body can handle. When people are diagnosed with type 2 diabetes, they often have ten times more insulin in their bodies than normal.

    Over time, the pancreas can no longer make enough insulin to keep blood sugar levels in check — even though it may still be making a lot! That’s because cells have become increasingly resistant to insulin’s effect. When this happens, blood sugar levels start to rise, and a person may be diagnosed with prediabetes or type 2 diabetes.

    Type 2 diabetes often affects people who are middle-aged or older, although it is becoming increasingly common in teenagers and young adults in poor metabolic health.

    Common symptoms of diabetes

    • Increased thirst and urination
    • Severe fatigue
    • Feeling hungrier than usual
    • Unexplained weight loss
    • Delayed healing of injuries
    • Blurred vision
    • Numbness and tingling in hands, feet or toes
    • Dark patches of skin
    • Skin rashes and lesions
    • Yeast and urinary tract infections (women)
    • Erectile dysfunction (men)

    For more details about these conditions, see our guide to symptoms of diabetes. However, please note that with prediabetes and early stages of type 2 diabetes, you  may not notice any symptoms.

    If you think you have any of the warning signs of diabetes, see your doctor.

2. Testing blood sugar

  1. Our guide on what you need to know about blood sugar can help you learn more about both high and low blood sugar. This guide focuses specifically on the high blood sugar levels that occur in diabetes.

    How do you know if you have too much sugar in your blood? If you don’t know already, it’s simple to test in a few seconds, either in your doctor’s office or with your own inexpensive blood glucose meter.

    Compare your own blood sugar reading with the ranges below:

    • Normal blood sugar: Less than 100 mg/dL (5.6 mmol/L ) after fasting overnight, and up to 140 mg/dL (7.8 mmol/L ) two hours after a meal
    • Prediabetes: Between 100-125 mg/dL (5.6-7.0 mmol/L) after fasting overnight
    • Diabetes: 126 mg/dL (7.0 mmol/L) or higher after fasting overnight, or higher than 200 mg/dL (11.1 mmol/L) at any time

    Keep in mind that you should not use glucometer readings alone to make a diagnosis of diabetes or prediabetes. If your blood sugar is high on a glucometer, ask your doctor to run a blood test to confirm the diagnosis. Also, most guidelines state that a single abnormal blood sugar reading is not sufficient to secure a diagnosis of diabetes; at least two are needed.

    If you are already on a low-carbohydrate diet and you are concerned about the measurements you’re getting, find out how a low-carb diet affects blood sugar measurements.

    Learn more about how to test your blood sugar

    If you are testing your blood sugar at home, read and follow the directions that come with your blood sugar meter. For most meters, the general procedure goes like this:

     

    1. With clean hands, place a test strip in your blood sugar meter.
    2. Prick the side of a finger with the lancet to draw a drop of blood.
    3. Place the tip of the test strip on the drop of blood.
    4. After a few seconds, the blood sugar meter will give you a reading.

3. Food & diabetes

  1. People with diabetes have difficulty keeping blood sugar levels in a normal range. The blood turns “too sweet” as glucose levels rise.

    Sugar in your blood comes from two places: your liver and the food that you eat. You can’t do much to control the amount of sugar your liver makes, but you can control the foods you eat.

    Foods are made up of three broad categories known as macronutrients (major nutrients): carbohydrate, protein, and fat. Many foods are a combination of two or all three macronutrients, but we often group foods according to whether they are mostly carbohydrate, protein, or fat.

Carbohydrates and blood sugar

Carbohydrates, or carbs, usually come from starches or sugars and turn into glucose when they are digested. When glucose enters the bloodstream, it’s called blood glucose, or blood sugar.

Carbohydrates

The more carbohydrate eaten in a meal, the more sugar is absorbed into the bloodstream and usually the higher the blood sugar will be.

Although very few people would agree that sugary foods are good for you, some foods that we think of as “healthy” — such as fruit — can have a lot of sugar. And many people don’t know that starchy foods — such as bread, rice, pasta, and potatoes — quickly turn to sugar when you digest them.

For some people, eating a potato could raise blood sugar as much as eating 9 teaspoons of sugar! It can be hard to predict exactly how someone’s blood sugar will respond, as this will likely vary based on genetics and baseline insulin sensitivity.

Protein

Protein containing foods include eggs, poultry, meat, seafood and tofu. Although individuals have different responses to these foods, consuming moderate amounts of protein at a meal generally has a mild to no effect on blood sugar.

Fat

Dietary fat by itself has practically no effect on blood sugar. However, we seldom eat fat all by itself. Some foods, like cheese, are made up of mostly protein and fat. These foods probably won’t raise your blood sugar very much.

But other foods, like doughnuts and French fries, are made up mostly of carbohydrate and fat. Because they’re high in carbs and fat together, these foods are likely to significantly raise your blood sugar.

4. How to lower blood sugar with diet

What happens if you remove foods that raise your blood sugar from your diet? Is there anything good left to eat? We think so. In fact, we have a whole guide on the best foods to control diabetes.

But a picture is worth a thousand words. These are just a few of the delicious foods that don’t raise blood sugar for just about everyone:

Many people with type 2 diabetes are now choosing a diet based primarily on low-carb foods, and many clinicians are catching on as well.

A person with type 2 diabete will often notice that, starting with the first meal, their blood sugar improves. The need for medications, especially insulin, is usually dramatically reduced. Substantial weight loss and health marker improvements often follow.

Choosing foods low in carbs is an effective way to help you control your blood sugar and is safe for most people. However, if you are taking medications for your diabetes, you must work with your healthcare provider to adjust your medications when you change your diet since the need for medications, especially insulin, may be greatly reduced.

If you are looking for a doctor who will work with you to control your diabetes with a change in diet, our map may help you find one.

5. The science of diabetes reversal

In 2019, the American Diabetes Association (ADA) stated that reducing carbohydrate intake was the most effective nutritional strategy for improving blood sugar control in those with diabetes.

Research shows that low-carb diets are a safe and effective option for treating type 2 diabetes. This body of evidence includes systematic reviews and meta-analyses of randomized controlled trials (the highest quality of evidence by our ratings.).

A meta-analysis from 2017 found that low-carb diets reduced the need for diabetes medication and also improved certain bio-markers in people with type 2 diabetes. This included reductions in hemoglobin A1c (HbA1c), triglycerides, and blood pressure; and increases in high-density lipoprotein (HDL) cholesterol, sometimes called the “good” cholesterol.

Additionally, in a non-randomized trial from Virta Health, the intervention group of subjects with type 2 diabetes followed a very low-carb diet and received remote monitoring by physicians and health coaches. After one year, 94% of those in the low-carb group had reduced or stopped their insulin use. Furthermore, 25% had an HgbA1c in the normal range without needing any medications, suggesting their disease was in remission, and an additional 35% did the same with only metformin.

At the two-year mark, a high proportion of subjects continued to demonstrate sustained improvements in glycemic control.

Other interventions have also demonstrated efficacy for inducing remission of type 2 diabetes, although there is a lack of consistency with how different trials define “remission.”

This evidence suggests that type 2 diabetes does not have to be a progressive and irreversible disease. It is clearly a treatable disease.

6. A message of hope

As recently as 50 years ago, type 2 diabetes was extremely rare. Now, around the world, the number of people with diabetes is increasing rapidly and is heading towards 500 million. This is a worldwide epidemic.

In the past, type 2 diabetes was thought to be a progressive disease with no hope for reversal or remission. People were — and sometimes still are — taught to “manage” type 2 diabetes, rather than to try to reverse the underlying process.

But now people with type 2 diabetes can hope to regain their health! Today we know that the hallmarks of type 2 diabetes — high blood sugar and high insulin — can often be reversed with a very low-carb diet, severe caloric restriction, or weight loss surgery.

People don’t just have to “manage” their diabetes as it progresses. Instead, they can often lower their blood sugar to normal levels with diet alone, and may be able to avoid or discontinue most medications.

Normal blood sugar levels and fewer or no medications likely means no progression of disease, and no progression of complications. People with a diagnosis of type 2 diabetes may be able to live long, healthy lives, with toes, eyesight, and kidneys intact!

If you are not on any medications, you can start your journey back to health today. If you are on medications for diabetes or for other conditions, consult your doctor before beginning any lifestyle change, such as a low-carb diet, so your medications are adjusted safely as your blood sugars improve.

It has been suggested that some children with autism may have a vitamin C deficiency. One theory is that children with autism have difficulty fighting off free radicals in their body, which can cause an imbalance in the body.

One study found that children with autism who took Vitamin C supplements saw a significant reduction in stereotypical behaviours such as rocking, flapping hands, and pacing. The sample size in this study was relatively small (18 participants), therefore further research is needed to examine the relationship more fully between autism and Vitamin C supplementation.
