Insulin resistance is a common condition that often has no clear symptoms at first, yet it can make weight loss harder and raise your risk of type 2 diabetes. In this guide, we explain what insulin resistance is, the signs to watch for, what causes it and practical ways to improve it.
What Is Insulin Resistance?
Insulin is a hormone made by the pancreas. After you eat, it helps move sugar (glucose) from your blood into your cells for energy. With insulin resistance, however, your muscle, fat and liver cells stop responding well to insulin. As a result, the pancreas has to make more and more insulin to keep blood sugar normal. Over time, it may not keep up, and blood sugar starts to rise.
Signs of Insulin Resistance
Many people have no symptoms for years. Still, some signs can point to a problem:
- Extra weight around the waist
- Dark, velvety patches of skin on the neck or armpits (acanthosis nigricans)
- Skin tags
- Strong cravings for sweets or carbs and energy crashes after meals
- High blood pressure, high triglycerides or low HDL (“good”) cholesterol
- Lab results in the prediabetes range, such as an A1C of 5.7% to 6.4% or fasting glucose of 100 to 125 mg/dL
Because signs can be subtle, lab work is the best way to know. For more detail, see this Cleveland Clinic overview of insulin resistance.
What Causes It?
Several factors work together. Excess belly (visceral) fat is one of the biggest drivers, because it releases substances that interfere with insulin. In addition, inactivity, poor sleep, chronic stress, certain medications, family history and conditions like PCOS all raise the risk. Age plays a role, too, since muscle mass tends to drop over time.
How to Improve Insulin Resistance
1. Move Your Muscles
Muscle is the largest user of blood sugar in the body. So, both strength training and regular walking help your cells respond better to insulin. Even a 10-minute walk after meals can lower blood sugar spikes.
2. Lose a Modest Amount of Weight
Losing just 5% to 7% of your body weight can significantly improve insulin sensitivity. For someone who weighs 200 pounds, that is 10 to 14 pounds.
3. Build Balanced Plates
Fill half your plate with non-starchy vegetables, a quarter with lean protein and a quarter with fiber-rich carbs. Our guide to the plate method for weight loss walks you through it step by step.
4. Sleep and Stress
Aim for seven to nine hours of sleep. Meanwhile, simple stress tools like walking, breathing exercises or time outdoors can help lower cortisol.
5. Consider Medical Support
For some people, lifestyle changes are not enough. In that case, a provider may suggest medication. For example, GLP-1 medications such as semaglutide and tirzepatide help lower blood sugar, reduce appetite and support weight loss in eligible patients.
