Did you know that one of the most common health problems in America is also one of the most preventable? Insulin resistance affects millions of people and is a leading cause of type 2 diabetes and other serious health problems. The good news is that simple lifestyle choices can help you avoid insulin resistance before problems begin.
What exactly is insulin resistance?
Insulin is a hormone that helps control your blood sugar. When you eat, much of your food is turned into glucose, also called blood sugar. This sugar enters your bloodstream and tells your pancreas to release insulin. The insulin acts like a key, helping glucose move from your bloodstream into your body’s cells, where it is used for energy. Insulin also helps the liver store extra glucose so it can be used later.
In a healthy body, this system works smoothly. But problems can start when too much sugar enters the bloodstream too often. When this happens, the pancreas must release more and more insulin to keep blood sugar levels under control. Over time, the body’s cells stop responding to insulin properly. This is called insulin resistance.
Be alert for the symptoms of insulin resistance
As insulin resistance gets worse, blood sugar levels can start to rise. This can lead first to prediabetes and later to type 2 diabetes. High blood sugar over long periods of time can damage the body and increase the risk of heart disease, stroke, kidney disease and other very serious conditions.
Many people with insulin resistance are unaware they have it. Others may notice symptoms like weight gain (especially around the belly), low energy, hunger and cravings, frequent thirst or urination, or dark patches of skin. Some people have no symptoms at all until blood sugar levels become too high. That’s why regular blood tests, such as at an annual checkup, are so important. It’s also important to know that you do not have to be overweight to have insulin resistance – it can happen to people with a normal body weight, too.
Eating right makes a difference
The good news is that insulin resistance can often be prevented or greatly improved with proper lifestyle changes. One of the most important steps is to cut back on sugary foods and foods containing added sugars. Processed and ultra processed foods often contain hidden sugars, as do drinks like soda and fruit juice. These should be avoided.
Instead, focus on eating whole, natural foods. These include vegetables, leafy greens, eggs, fish, meat, hard cheeses, and whole fruits. Foods high in fiber are especially helpful because they slow down how fast sugar enters the bloodstream. Be mindful of starchy foods like bread, rice, and pasta, since they can raise blood sugar quickly. Physical activity also plays a big role. Even a short walk after meals helps your muscles use extra glucose, which lowers blood sugar levels. You don’t have to start with intense workouts—small, consistent movement makes a difference too.
Prevention is key
If you think you might have insulin resistance, talk with your primary care provider. They can test your blood sugar levels to find out. Most importantly, if you have insulin resistance, be sure to take action. With a healthier diet, regular exercise, and medication when needed, you can avoid the many serious health problems caused by insulin resistance. A little prevention today can make a big difference for your health tomorrow!
