Introduction
Insulin resistance is a condition where the body’s cells become less sensitive to insulin, a hormone that regulates blood sugar. According to the American Diabetes Association, about 88 million American adults have insulin resistance, with risk factors including a family history of diabetes, obesity, physical inactivity, PCOS, and certain other medical conditions.

Causes of Insulin Resistance
Insulin resistance can be caused by a variety of factors, let’s delve int to these a bit deeper:
Genetics: Insulin resistance can be inherited genetically. Some people may be more susceptible to developing insulin resistance due to their genetic makeup. Individuals with a strong family history of a parent and grandparent (or both) with diabetes can have a genetic risk to develop insulin resistance.
Sedentary Lifestyle: A sedentary lifestyle with little physical activity can lead to insulin resistance. Exercise helps improve insulin sensitivity and glucose metabolism, reducing the risk of insulin resistance. You should make moving a priority throughout life especially if you do have a family history of diabetes.
Obesity: Obesity is a significant risk factor for insulin resistance, as excess fat can interfere with insulin signaling and increase inflammation in the body. If you are carrying around an extra 30 or more pounds of belly fat, chances are you fit this category and our officially obese.
Poor Diet: Consuming a diet high in processed and sugary foods can lead to insulin resistance. These types of foods can cause spikes in blood sugar levels, leading to insulin resistance over time.
Sleep Deprivation: Lack of sleep or poor sleep quality can interfere with insulin sensitivity and glucose metabolism, leading to insulin resistance.
Aging: As we age, our bodies become less efficient at using insulin, leading to a higher risk of developing insulin resistance. also, as we age most of our hormones decrease allowing hormone imbalance to be an aggravating factor to poor insulin quality.
Medications: Certain medications, such as corticosteroids and antipsychotics, can interfere with insulin signaling and lead to insulin resistance.
Medical Conditions: Certain medical conditions, such as polycystic ovary syndrome (PCOS), metabolic syndrome, and Cushing’s syndrome, can increase the risk of insulin resistance.
Understanding the causes of insulin resistance is important in preventing its development and managing its effects.
Symptoms of Insulin Resistance
Insulin resistance can cause a range of symptoms, including:
- High Blood Sugar: Insulin resistance can cause high blood sugar levels, as the body’s cells become less responsive to insulin, which helps to regulate blood sugar.
- Weight Gain: Insulin resistance can cause weight gain, particularly around the abdomen, as the body stores excess glucose as fat.
- Fatigue: Insulin resistance can cause feelings of fatigue or lethargy, as the body struggles to use glucose effectively for energy.
- Increased Hunger: Insulin resistance can increase feelings of hunger, as the body’s cells are not getting the glucose they need for energy.
- Brain Fog: Insulin resistance can cause brain fog, difficulty concentrating, or memory problems, as the brain is not getting the glucose it needs for optimal function.
- Skin Changes: Insulin resistance can cause changes in the skin, including dark patches on the skin (acanthosis nigricans) and skin tags.
It’s important to note that some people with insulin resistance may not experience any noticeable symptoms, particularly in the early stages of the condition.
This is why having blood tests to check for the condition is so important. Having your fasting glucose checked repeatedly is an inefficient way to determine if you have insulin resistance.
Diagnosis and Treatment
Insulin resistance is diagnosed through blood tests that measure insulin and glucose levels, as well as through physical exams to check for signs of the condition. Treatment for insulin resistance often involves lifestyle changes like healthy eating and regular exercise, which can help to improve insulin sensitivity and regulate blood sugar levels. Medications like metformin may also be prescribed to help manage the condition. Working with a healthcare provider is essential in developing a treatment plan that works best for you.
Getting the Diagnosis
There are several tests that can help diagnose insulin resistance. These include:
- Fasting Insulin Test: This blood test measures the level of insulin in the bloodstream after an overnight fast. High levels of insulin can indicate insulin resistance.
- Fasting Glucose Test: This blood test measures the level of glucose in the bloodstream after an overnight fast. High levels of glucose can indicate insulin resistance.
- Oral Glucose Tolerance Test (OGTT): This test involves drinking a sweetened beverage, and then having blood drawn at various intervals to measure blood sugar and insulin levels. The results can help diagnose insulin resistance.
- Hemoglobin A1C Test: This blood test measures the average level of blood sugar over the past two to three months. Elevated levels of hemoglobin A1C can indicate insulin resistance.
- Homeostatic Model Assessment of Insulin Resistance (HOMA-IR): This is a calculation that uses fasting blood sugar and insulin levels to estimate insulin resistance.
These tests are your best chance of getting a definitive diagnosis of insulin resistance. All of these tests are not usually necessary since some are more sensitive and specific but it is important to take into account other factors, such as your medical history, family history, and other symptoms to help determine which testing is best for you.
Prevention
Preventing insulin resistance starts with making healthy lifestyle choices. Maintaining a healthy weight, eating a balanced diet that is low in processed and sugary foods, and staying physically active are all key to preventing insulin resistance. Additionally, avoiding smoking and excessive alcohol consumption can help reduce the risk of developing the condition. Small changes to your lifestyle can have a big impact on your overall health.
There are several ways to prevent insulin resistance, including:
- Healthy Diet: A healthy insulin resistance diet can help prevent insulin resistance. Focus on eating a balanced diet that is rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Avoid consuming large amounts of sugary or processed foods, which can contribute to insulin resistance.
- Regular Exercise: Regular exercise can help prevent insulin resistance by improving insulin sensitivity. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Weight Management: Maintaining a healthy weight can help prevent insulin resistance, as excess weight can interfere with insulin signaling.
- Stress Management: Stress can contribute to insulin resistance, so finding ways to manage stress, such as through meditation, deep breathing, or yoga, can be helpful.
- Quality Sleep: Getting enough sleep and maintaining good sleep habits can help prevent insulin resistance.
- Supplementation: Some supplements, such as magnesium, chromium, and alpha-lipoic acid, may help prevent or manage insulin resistance.
Lifestyle Specifics
When it comes to managing insulin resistance, certain eating plans and natural supplements can be beneficial. Here are some options to consider:
Insulin Resistance Diets and Eating Plans:
a) Low Glycemic Index (GI) Diet: Focus on consuming foods with a low glycemic index, which means they have a slower and steadier impact on blood sugar levels. This includes whole grains, legumes, non-starchy vegetables, and lean proteins.
b) Mediterranean Diet: Emphasizes whole foods, healthy fats (such as olive oil), lean proteins, fruits, vegetables, and whole grains. It also limits processed foods, red meats, and sugary treats.
c) DASH Diet: The Dietary Approaches to Stop Hypertension (DASH) diet promotes a well-rounded approach with an emphasis on fruits, vegetables, whole grains, lean proteins, and low-fat dairy products.
Natural Supplements:
- Chromium: This mineral plays a role in regulating blood sugar levels. It may help improve insulin sensitivity and glucose metabolism.
- Magnesium: Adequate magnesium levels are important for insulin sensitivity. Consider adding magnesium-rich foods to your diet or consult with a healthcare professional regarding supplements.
- Alpha-Lipoic Acid (ALA): ALA is an antioxidant that may improve insulin sensitivity and reduce oxidative stress associated with insulin resistance.
- Cinnamon: Some studies suggest that cinnamon may help improve insulin sensitivity and glucose metabolism. However, it’s essential to use it as a supplement under professional guidance.
Additional Supplements to Consider
N-acetylcysteine (NAC) is a dietary supplement that has gained attention for its potential benefits in various health conditions. While research suggests that NAC may have some positive effects on insulin resistance, it’s important to note that the evidence is limited, and further studies are needed to establish its efficacy.
NAC is known for its antioxidant properties and its ability to replenish glutathione, an important antioxidant in the body. Some studies have shown that NAC may improve insulin sensitivity and reduce markers of insulin resistance in certain populations, such as individuals with polycystic ovary syndrome (PCOS) or those with non-alcoholic fatty liver disease (NAFLD).
Berberine is a natural compound extracted from various plants, including the roots of the barberry shrub. It has been studied for its potential benefits in managing insulin resistance and related conditions.
Research suggests that berberine may help improve insulin sensitivity, reduce blood sugar levels, and regulate glucose metabolism. It appears to work by activating an enzyme called AMP-activated protein kinase (AMPK), which plays a crucial role in regulating cellular energy metabolism. Additionally, berberine may help decrease inflammation and improve lipid metabolism.
Several clinical studies have demonstrated the positive effects of berberine in people with insulin resistance and type 2 diabetes. It has been shown to reduce fasting blood sugar levels, improve glucose tolerance, and enhance insulin sensitivity.
While NAC and berberine show promise in relation to insulin resistance, they should not replace lifestyle changes, such as a healthy diet, regular exercise, and weight management, which are fundamental for managing insulin resistance effectively.
Common Medications for Insulin Resistance
There are several medications that can be used to treat insulin resistance. These include:
- Metformin: This is a commonly prescribed medication for insulin resistance and type 2 diabetes. It works by reducing glucose production in the liver and improving insulin sensitivity in the body’s cells.
- Thiazolidinediones (TZDs): TZDs work by improving insulin sensitivity in the body’s cells and reducing glucose production in the liver.
- Alpha-glucosidase inhibitors: These medications work by slowing the breakdown of carbohydrates in the digestive tract, which helps to prevent spikes in blood sugar levels.
- DPP-4 inhibitors: DPP-4 inhibitors work by increasing the level of a hormone called GLP-1, which helps to regulate blood sugar levels.
- GLP-1 receptor agonists: These medications work by mimicking the effects of GLP-1, which helps to regulate blood sugar levels and improve insulin sensitivity.
- Insulin: In some cases, insulin therapy may be necessary to treat insulin resistance. Insulin is a hormone that helps to regulate blood sugar levels and can be given by injection or via an insulin pump.
It’s important to note that these medications should only be used under the guidance of a healthcare provider and still should be combined with lifestyle changes, such as diet and exercise, for optimal results. Additionally, some medications may have side effects, so it’s important to discuss any concerns with your healthcare provider.
Living with Insulin Resistance
Living with insulin resistance can be challenging, but there are many self-care modalities for you to be actively involved.
Self-care is an important aspect of managing insulin resistance, and there are several steps that someone with insulin resistance can take to care for themselves. These include:
