The Early Warning Signs of Insulin Resistance 

November 10, 2026

Your blood sugar came back normal. Still, you crave sweets every afternoon, your waistband feels tighter each year, and lunch leaves you ready for a nap. Sound familiar? These insulin resistance symptoms often show up years before a diabetes diagnosis, yet many people write them off as part of getting older. 

At Hotze Health & Wellness Center, we’ve helped more than 33,000 guests (we call our patients guests) over the past 35 years. Many of them come to us after seeing several doctors who said everything looked fine. We listen first. Then we dig deeper to find the root cause. 

What Is Insulin Resistance? 

Insulin is the hormone that moves sugar from your bloodstream into your cells for energy. With insulin resistance, your cells stop responding to that signal as well as they should. As a result, your pancreas pumps out more and more insulin to keep blood sugar in range. 

For a while, this extra effort works. Your glucose stays steady, so standard tests look fine. Behind the scenes, however, insulin levels keep climbing. Eventually, the pancreas can’t keep up, and blood sugar starts to rise. 

This problem is far more common than most people realize. About 98 million American adults have prediabetes, and more than 8 in 10 of them don’t know it.¹ In fact, one long-term study of British adults found that insulin sensitivity declined in the years before doctors diagnosed type 2 diabetes.² 

7 Early Insulin Resistance Symptoms to Watch 

Insulin resistance rarely announces itself. Instead, it sends quiet signals that are easy to overlook. Common signs of insulin resistance include: 

• Belly fat or a growing waistline 

• Strong cravings for sweets or carbs 

• Fatigue or brain fog after meals 

• Hunger soon after eating 

• Skin tags on the neck, underarms, or chest 

• Dark, velvety patches of skin 

• Weight that won’t budge despite your best efforts 

So why do these signs appear? Abdominal fat, especially the deep fat around your organs, is closely tied to insulin resistance.³ Similarly, sugary and refined meals can spike insulin and then drop your blood sugar. One study found that a high-glycemic meal led to lower blood sugar hours later and more eating afterward.⁴ 

Skin changes can supply clues, too. Researchers found that people with three or more skin tags had diabetes nearly three times as often as matched controls.⁵ Of course, none of these signs alone confirms insulin resistance. Together, though, they’re worth a closer look. 

Why Normal Blood Sugar Can Hide Insulin Resistance Symptoms 

Most routine checkups measure fasting glucose and sometimes A1c. Both tests track sugar, not insulin. Consequently, if your pancreas works overtime to hold glucose steady, your numbers can look perfectly normal. 

Decades ago, pathologist Dr. Joseph Kraft measured insulin during thousands of glucose tolerance tests. His work showed that many people with normal glucose already had abnormal insulin patterns.⁶ Standard lab ranges are also broad, so “normal” doesn’t always mean optimal. 

Insulin doesn’t work alone, either. High insulin also affects other hormones, including estrogen, leptin, and adiponectin.⁷ Over time, your body depletes hormones and nutrients. When that happens, the answer is to replenish them. Learn more about our approach to hormone balancing for women and men. 

How We Test for Early Insulin Resistance 

At Hotze Health & Wellness Center, we combine your clinical symptoms with comprehensive lab testing. That way, we build a complete picture of your health instead of relying on standard bloodwork alone. Our comprehensive lab testing may include markers like these: 

Marker	What It Shows
Fasting insulin	How hard your pancreas works to keep glucose steady
Fasting glucose	Your blood sugar after an overnight fast
Hemoglobin A1c	Your average blood sugar over about three months
Triglycerides and HDL	Blood fats that often shift with insulin resistance

Most importantly, we listen. Your symptoms tell us just as much as your numbers do. 

Turning Insulin Resistance Symptoms Around 

Here’s the encouraging part: insulin resistance often responds well to lifestyle changes. In the landmark Diabetes Prevention Program, a lifestyle program lowered the risk of developing type 2 diabetes by 58% in adults with prediabetes.⁸ Simple daily habits can support healthy insulin sensitivity: 

• Build meals around protein, healthy fats, and fiber. 

• Cut back on sugar and refined carbs. 

• Move every day, including strength training. 

• Get 7 or more hours of sleep. 

• Manage stress 

At Hotze Health & Wellness Center, we treat the whole body, not merely an isolated symptom. Your provider looks at nutrition, gut health, hormones, and nutrient status together. In this way, we not only get to the root cause of your symptoms, but we also focus on prevention and healthspan. As a population, we’re living longer, and we believe those longer years should be quality years.
