In the world of metabolic health, few conditions are as prevalent—yet as misunderstood—as insulin resistance. This underlying issue is at the core of prediabetes and type 2 diabetes, affecting millions of people, often without noticeable symptoms. Understanding insulin resistance and taking proactive steps to manage it can be the key to preventing long-term complications.
What is Insulin Resistance?
Insulin is a hormone produced by the pancreas that helps regulate blood sugar (glucose) levels. When you eat, carbohydrates break down into glucose, which enters your bloodstream. In response, your pancreas releases insulin, which helps shuttle glucose into your cells to be used for energy.
However, in insulin resistance, your cells become less responsive to insulin’s signals. This forces your pancreas to work harder, releasing more insulin to keep blood sugar levels in check. Over time, this chronic overproduction of insulin leads to high blood sugar levels, prediabetes, and eventually type 2 diabetes if left unchecked.
Signs and Symptoms of Insulin Resistance
Most people with insulin resistance do not experience symptoms until blood sugar levels start to rise significantly. However, some subtle signs can indicate an underlying issue, including:
Increased belly fat – Especially visceral fat around the abdomen
Cravings for sugar and refined carbs
Fatigue after meals
Skin darkening (acanthosis nigricans) – Common in the neck, armpits, or groin
Difficulty losing weight despite diet and exercise
High blood pressure or cholesterol imbalances
If left unchecked, insulin resistance can progress to prediabetes, characterized by slightly elevated blood sugar levels, and then to type 2 diabetes, where blood sugar control is lost.
How Insulin Resistance Leads to Prediabetes and Diabetes
Increased insulin demand: As insulin resistance worsens, the pancreas produces more insulin to compensate.
Pancreatic burnout: Over time, the pancreas struggles to keep up, leading to insufficient insulin production.
Elevated blood sugar: With less insulin available and increased resistance, blood glucose levels begin to rise.
Progression to diabetes: When fasting blood sugar reaches 126 mg/dL or higher (or HbA1c is 6.5% or more), a diabetes diagnosis is made.
How to Help Reverse Insulin Resistance
The good news? Insulin resistance is reversible, especially in its early stages. Here’s how:
1. Prioritize Strength Training & Movement
Exercise is one of the most powerful tools for reversing insulin resistance. Strength training increases muscle mass, which improves insulin sensitivity. Aim for at least 3-4 days of resistance training per week and daily movement, such as walking after meals.
2. Optimize Your Diet
Focus on:
Protein-rich meals (lean meats, eggs, fish, Greek yogurt)
Healthy fats (avocados, nuts, olive oil)
High-fiber, non-starchy vegetables (leafy greens, broccoli, asparagus)
Low-glycemic carbs (quinoa, lentils, berries in moderation)
Eliminate processed foods, added sugars, and refined carbs like white bread and sodas.
3. Improve Sleep Quality
Poor sleep directly contributes to insulin resistance by increasing cortisol (stress hormone) and reducing insulin sensitivity. Prioritize 7-9 hours of high-quality sleep per night.
4. Manage Stress & Cortisol
Chronic stress raises blood sugar and insulin resistance. Try:
Daily breathwork or meditation
Prioritizing recovery time
Limiting excessive caffeine intake
5. Consider Targeted Supplements (Under Medical Supervision)
Berberine – Mimics metformin in improving insulin sensitivity
Magnesium – Supports glucose metabolism
Omega-3s – Reduces inflammation linked to insulin resistance
Inositol – Beneficial for insulin sensitivity, especially in women with PCOS
When to Get Tested for Insulin Resistance
If you experience weight gain, sugar cravings, energy crashes, or have a family history of diabetes, you may want to have your labs checked.
Reversing insulin resistance is possible with early intervention and lifestyle adjustments. At Vitality, you have the unique advantage of personalized guidance, continuous monitoring, and advanced testing to optimize your metabolic health.
