What is Insulin Resistance?
Insulin resistance is a common health problem that affects millions of people worldwide. It is a condition where the body becomes resistant to the hormone insulin, which is responsible for regulating blood sugar levels. Insulin resistance is a precursor to prediabetes, and eventually, type 2 diabetes, and it can lead to a range of health problems if left untreated.
The Prevalence of Prediabetes
In the United States alone, there are 70 to 80 million people with prediabetes, a condition where blood sugar levels are abnormal but not yet in diabetic ranges. Insulin resistance is a significant contributor to prediabetes. Insulin resistance can occur for 10 to 15 years before blood sugar levels become abnormal.
How Insulin Works in the Body
Insulin is released from the pancreas in response to meals that are high in sugar or carbohydrates. Its job is to bind receptors in every cell and open the gates so that sugar can enter the cells. Sugar, in the form of glucose, is essential for the body as it provides fuel for the muscles, brain, immune system, and gut. However, a diet that is high in sugar, processed foods, and refined carbohydrates like bread and pasta can lead to increased insulin production followed by a failure of the cells of the body to respond to the insulin being produced.
The Vicious Cycle of Insulin Resistance and Weight Gain
In this case, it takes more insulin to get sugar out of the bloodstream and into the cells. Over time, the cells stop listening to the insulin signal, and the body becomes adapted to the response. As insulin resistance worsens, the body starts to store fat, and weight gain becomes more prevalent. It takes more insulin to get sugar out of the cells, which leads to a vicious cycle of worsening insulin resistance and weight gain.
The Long-Term Consequences
Once the blood glucose and hemoglobin A1C levels (a blood marker that gives us an average of blood sugar levels over a 3 month period of time) start to rise, insulin resistance has already been present for 10 to 15 years. If nothing is done about it, people will go on to develop type 2 diabetes within the next 5 to 6 years. The good news is that insulin resistance is reversible with lifestyle changes, supplements, exercise, and medication.
The Role of Diet in Managing Insulin Resistance
Diet and nutrition are crucial in managing insulin resistance. Sugar is a drug that changes our brain, making us want more of it. Cutting out sugar and limiting processed foods, including pretzels, chips, bread, and pasta, can help manage insulin resistance. The diet should focus on 5 to 7 servings of vegetables a day, limiting fruit intake, and cutting added sugar down to no more than 20 to 25 grams per day. Choosing whole grains instead of refined grains can also help in managing insulin resistance.
Exercise and Insulin Sensitivity
Exercise can also help decrease insulin resistance. It is important to include a variety of types of exercise including stretching/yoga, aerobic activity, and weight/resistance training. Interval training with bursts of more intense activity is especially effective for this condition.
The Importance of Sleep
Getting adequate sleep is another critical factor in the management of insulin resistance. Anything less than 7 hours a night will raise fasting insulin and blood glucose levels the following morning.
Managing Stress to Control Insulin Resistance
Because of the effects of the stress hormone, cortisol, on blood sugar production in the liver, it is important to manage and mitigate the effects of life stressors on the body. In addition to exercise and sleep, deep breathing, meditation, and mindfulness can be extremely helpful to keep cortisol levels under control.
Supplements and Medications for Insulin Resistance
A range of nutraceuticals may help manage blood sugar but are much less effective if dietary changes are not made. If all of the above are being done and insulin resistance persists, metformin can be an effective medication at preventing the progression to type 2 diabetes.
Conclusion: Taking Control of Your Health
In conclusion, insulin resistance is a serious health problem that can lead to type 2 diabetes and other health problems. However, it is reversible with lifestyle changes, including diet and nutrition, supplements, exercise, and medication. Managing insulin resistance is crucial in preventing prediabetes and type 2 diabetes and leading a healthy life.
