Many people hear terms like insulin resistance, prediabetes, and insulin dependence but may not fully understand what they mean or how they’re connected. By understanding how insulin functions in your body, you can take steps to protect your long-term health and prevent chronic conditions like type 2 diabetes.
What Is Insulin and What Does It Do?
Insulin is a hormone made by your pancreas that helps manage blood sugar levels. After you eat, your blood sugar rises—and insulin’s job is to move that sugar out of your bloodstream and into your cells. Your body uses the sugar for immediate energy. But when energy needs are already met, insulin helps store the extra sugar as fat, particularly in fat cells and the liver.
This process is essential for survival, but when insulin levels stay high for long periods—mainly due to a poor diet, and also from lack of physical activity or chronic stress—it can lead to weight gain and metabolic problems.
What Is Insulin Dependence?
Insulin dependence refers to a condition where a person must rely on insulin injections to manage their blood sugar. This can occur in both type 1 and type 2 diabetes, but for different reasons:
In type 1 diabetes, the immune system mistakenly attacks insulin-producing cells in the pancreas. The body stops making insulin altogether, and insulin must be taken daily from the start.
In type 2 diabetes, insulin resistance develops gradually. The body still produces insulin, but the cells don’t respond to it properly. Over time, the pancreas can wear out from overworking, and insulin injections may eventually become necessary.
How Insulin Resistance Leads to Prediabetes and Diabetes
Many people first go through a stage of insulin resistance—where the body still makes insulin, but the cells no longer respond to it effectively. This causes the pancreas to work overtime and insulin levels to stay high. Over time, this leads to prediabetes, where blood sugar levels become unhealthy, but not yet technically in the diabetic range.
This is a critical time for intervention. Without lifestyle changes, prediabetes often progresses to type 2 diabetes, where blood sugar levels remain chronically elevated and may require medication or insulin therapy.
What You Can Do to Support Healthy Insulin Function
The good news is that insulin resistance and prediabetes can often be reversed through lifestyle changes, especially in the early stages. Here are some key steps:
Move your body regularly—exercise helps your cells respond better to insulin
Choose whole, unprocessed foods with plenty of fiber and lean protein
Reduce added sugars and refined carbs
Manage stress and prioritize quality sleep
Maintain a healthy weight
If you’re worried about your metabolic health or insulin sensitivity, a great first step is to test your fasting insulin levels. This simple blood test can reveal early signs of insulin resistance—often before blood sugar levels rise. Elevated fasting insulin is an early marker that your body is struggling to keep glucose in check, even if your blood sugar still appears normal.
