W8MD Weight Loss, Sleep and MedSpa physicians help patients identify and treat insulin resistance through evidence-based medical weight management, nutrition counseling, medications, and sleep medicine.
Acanthosis nigricans may be a visible skin sign of insulin resistance.
Acanthosis nigricans is more common in people with obesity, insulin resistance, prediabetes, PCOS, and type 2 diabetes risk.
Insulin resistance is a common but under-recognized driver of weight gain, abdominal obesity, cravings, prediabetes, PCOS, and type 2 diabetes.
A low-glycemic, protein-forward, lower-carbohydrate dietary pattern may help reduce insulin demand and support weight loss in insulin-resistant patients.
Structured meal replacements may help selected W8MD patients reduce glycemic load, improve protein intake, and support medically supervised weight loss.
Sleep apnea can worsen insulin resistance, fatigue, hunger, cravings, and weight gain; W8MD integrates sleep medicine with medical weight management.
Weight loss and long-term maintenance can improve insulin resistance and reduce future diabetes risk.
Insulin resistance is a major pathway leading to prediabetes, type 2 diabetes, gestational diabetes, and cardiometabolic disease.

Insulin resistance is a metabolic condition in which the body's cells do not respond normally to insulin. Insulin is a hormone produced by the pancreas that helps regulate blood glucose by allowing the body's cells to use glucose for energy. In people with insulin resistance, muscle, liver, and fat cells do not respond to insulin as effectively. As a result, the pancreas must produce more insulin to keep blood sugar levels normal.

Insulin resistance can exist for years before blood sugar becomes high enough to diagnose prediabetes or type 2 diabetes. During this earlier stage, many patients may already have weight gain, abdominal obesity, sugar cravings, fatigue after high-carbohydrate meals, high triglycerides, low HDL cholesterol, irregular periods, PCOS, fatty liver disease, or metabolic syndrome. For this reason, insulin resistance is one of the most common but under-recognized causes of weight gain and metabolic disease.

W8MD Weight Loss, Sleep and MedSpa physicians have over 16 years of experience helping patients with insulin resistance-related weight gain, prediabetes, type 2 diabetes risk, PCOS, metabolic syndrome, history of gestational diabetes, sleep apnea, and long-term weight management. W8MD can help patients identify insulin resistance early and create a personalized plan using evidence-based medical weight management, low-glycemic nutrition, low-carbohydrate or ketogenic diet plans when appropriate, culturally customized meal planning, structured meal replacements, GLP-1 medications when appropriate, traditional weight-loss medications when appropriate, exercise counseling, and sleep apnea evaluation.

Overview

Insulin resistance is one of the central metabolic problems behind many common chronic conditions. It may be present even when routine glucose tests are still normal.

Insulin resistance is strongly associated with:

The National Institute of Diabetes and Digestive and Kidney Diseases describes insulin resistance as a condition in which the body does not respond to insulin as it should, which can lead to increased blood glucose and weight gain.Insulin Resistance and Prediabetes(link). National Institute of Diabetes and Digestive and Kidney Diseases.

What insulin does

Insulin is an anabolic hormone that helps the body store and use energy. It is released by the beta cells of the pancreas, especially after meals containing carbohydrates and protein.

Insulin helps:

  • Move glucose from the bloodstream into muscle cells
  • Store glucose as glycogen in the liver and muscles
  • Reduce glucose production by the liver
  • Promote fat storage when energy intake is high
  • Reduce fat breakdown when insulin levels are elevated
  • Regulate protein and lipid metabolism
  • Maintain blood glucose within a healthy range

When insulin signaling works normally, the body can keep glucose in a healthy range with normal insulin levels. In insulin resistance, the body requires higher insulin levels to produce the same effect.

What is insulin resistance?

Insulin resistance means that the body's cells are resistant to the action of insulin. The pancreas compensates by producing more insulin. This compensatory high-insulin state is called hyperinsulinemia.

Over time, insulin resistance can progress through several stages:

  1. Normal glucose with high insulin levels.
  2. Impaired fasting glucose or impaired glucose tolerance.
  3. Prediabetes.
  4. Type 2 diabetes when the pancreas can no longer produce enough insulin to overcome resistance.

Many patients are in the first stage for years and do not realize they are insulin resistant.

Why insulin resistance is under-recognized

Insulin resistance is often missed because common screening tests focus on glucose rather than insulin. Fasting glucose and HbA1c may remain normal while insulin levels are already elevated.

Insulin resistance may be under-recognized because:

  • Fasting glucose may be normal for years
  • HbA1c may not detect early insulin overproduction
  • Fasting insulin is not routinely checked
  • Patients may be told their labs are “normal”
  • Weight gain may be blamed only on willpower
  • PCOS may be treated without addressing metabolic drivers
  • Gestational diabetes may be treated as a temporary pregnancy issue
  • Sleep apnea may be missed
  • High triglycerides and low HDL may not be linked back to insulin resistance

Mechanism

The exact mechanisms of insulin resistance are complex and involve genetics, body fat distribution, diet, physical activity, inflammation, sleep, stress, hormones, and cellular energy metabolism.

Major mechanisms include:

  • Abdominal and visceral fat accumulation
  • Chronic low-grade inflammation
  • Excess calorie intake
  • High-glycemic dietary patterns
  • Ectopic fat in liver and muscle
  • Mitochondrial dysfunction
  • Oxidative stress
  • Physical inactivity
  • Sleep deprivation
  • Untreated sleep apnea
  • Hormonal changes during pregnancy
  • PCOS-related androgen and insulin interactions

Visceral fat is especially important because it is metabolically active and can release inflammatory signals and fatty acids that worsen insulin signaling.

How insulin resistance causes weight gain

Insulin resistance can contribute to weight gain through several overlapping pathways.

Mechanism Effect
Higher insulin levels High insulin promotes energy storage and can make it harder to access stored fat
Fat storage tendency Insulin encourages storage of excess energy in fat cells
Sugar and starch cravings Blood sugar and insulin fluctuations can increase hunger and cravings
Abdominal obesity Visceral fat worsens insulin resistance and inflammation
Fatigue after meals Post-meal glucose and insulin swings may reduce activity and increase snacking
Metabolic syndrome High triglycerides, low HDL, high blood pressure, and abdominal obesity cluster together

Insulin resistance does not mean weight gain is the patient's fault. It means the body is operating in a metabolic environment that favors hunger, fat storage, and difficulty losing weight.

Metabolic starvation and food cravings

Some insulin-resistant patients experience a pattern sometimes described as metabolic starvation. In this state, high insulin levels keep fat stores relatively locked away, while blood sugar fluctuations and hunger signals make the patient feel driven to eat, especially starchy or sugary foods.

Patients may report:

  • Cravings for bread, rice, pasta, potatoes, sweets, or snacks
  • Hunger soon after eating carbohydrates
  • Fatigue after meals
  • Difficulty fasting
  • Irritability when meals are delayed
  • Night eating or late snacking
  • Weight gain despite attempts to restrict calories

This is one reason why many insulin-resistant patients do better with protein-first, lower-glycemic, lower-carbohydrate meal plans rather than traditional high-carbohydrate, low-fat diets.

Symptoms and signs

Insulin resistance is often silent. Some patients have no symptoms until prediabetes or type 2 diabetes develops.

Possible signs include:

  • Weight gain
  • Upper-body or abdominal weight gain
  • Large waist circumference
  • Sugar cravings
  • Starchy food cravings
  • Fatigue after carbohydrate-rich meals
  • Frequent hunger
  • Skin tags
  • Acanthosis nigricans
  • High triglycerides
  • Low HDL cholesterol
  • Elevated blood pressure
  • Irregular periods
  • PCOS symptoms
  • History of gestational diabetes
  • Snoring or suspected sleep apnea

Acanthosis nigricans

Acanthosis nigricans is a dark, thickened, velvety skin change that may appear on the neck, underarms, groin, elbows, or other body folds. It is commonly associated with high insulin levels and insulin resistance.

Acanthosis nigricans should prompt evaluation for:

  • Insulin resistance
  • Prediabetes
  • Type 2 diabetes
  • PCOS
  • Obesity
  • Metabolic syndrome

Skin tags

Skin tags are small, soft skin growths that may be associated with insulin resistance, obesity, and metabolic syndrome. They are not diagnostic by themselves but can be a clue when combined with weight gain, acanthosis nigricans, high triglycerides, or family history of diabetes.

Conditions linked to insulin resistance

Prediabetes

Prediabetes occurs when blood glucose is higher than normal but not high enough for type 2 diabetes. It is often a sign of underlying insulin resistance and beta-cell stress.

Prediabetes is a warning stage. Weight loss, nutrition change, physical activity, and medical management can reduce progression to type 2 diabetes.

Type 2 diabetes

Type 2 diabetes develops when insulin resistance combines with progressive beta-cell dysfunction. At first, the pancreas may produce extra insulin. Later, insulin production may not keep up with demand, causing chronic hyperglycemia.

Metabolic syndrome

Metabolic syndrome is a cluster of risk factors strongly linked to insulin resistance.

Features include:

  • Abdominal obesity
  • High triglycerides
  • Low HDL cholesterol
  • Elevated blood pressure
  • Elevated fasting glucose

Metabolic syndrome increases risk for type 2 diabetes, cardiovascular disease, fatty liver disease, and stroke.

PCOS

PCOS or polycystic ovary syndrome is closely linked to insulin resistance. Insulin resistance may worsen weight gain, androgen excess, irregular periods, acne, facial hair growth, infertility, and lifetime diabetes risk.

A 2025 review reported that insulin resistance is highly prevalent in women and adolescents with PCOS, with estimates ranging from 35% to 80%, and noted that PCOS is associated with increased diabetes risk."Insulin resistance, metabolic syndrome and polycystic ovaries".Frontiers in Endocrinology.2025;PMC:12520869.

Fatty liver disease

Fatty liver disease is commonly associated with insulin resistance, abdominal obesity, high triglycerides, and type 2 diabetes risk. Reducing weight, improving insulin sensitivity, lowering refined carbohydrates, and increasing physical activity may help reduce liver fat in many patients.

Sleep apnea

Sleep apnea is common in obesity and may worsen insulin resistance through sleep fragmentation, intermittent oxygen drops, stress-hormone activation, fatigue, and increased hunger.

Gestational diabetes

Gestational diabetes is diabetes that develops during pregnancy. Pregnancy normally increases insulin resistance, especially in the second and third trimesters. Placental hormones help support fetal growth but can make the mother's body less sensitive to insulin.

The CDC explains that all pregnant women have some insulin resistance during late pregnancy, but some women have insulin resistance even before pregnancy, start pregnancy with a higher need for insulin, and are more likely to develop gestational diabetes.Gestational Diabetes(link). Centers for Disease Control and Prevention.May 15, 2024.

Pregnancy as a metabolic stress test

Pregnancy can be understood as a metabolic stress test. In a metabolically healthy person, the pancreas can produce enough additional insulin to overcome pregnancy-related insulin resistance. In someone with underlying subclinical insulin resistance, pregnancy may reveal the problem as gestational diabetes.

The American Diabetes Association Standards of Care in Diabetes—2026 notes that pregnancy is characterized by progressive insulin resistance in the second and third trimesters due to diabetogenic placental factors."15. Management of Diabetes in Pregnancy: Standards of Care in Diabetes—2026".Diabetes Care.2026;49(Supplement_1)

S321-S335.doi:10.2337/dc26-S015.

A history of gestational diabetes should therefore be treated as a warning sign for future insulin resistance, prediabetes, and type 2 diabetes risk.

Diagnosis

The diagnosis of insulin resistance may be clinical, laboratory-based, or both. There is no single routine test used universally in everyday clinical practice, but several markers can help.

Test or finding Why it matters
Waist circumference Abdominal obesity is strongly linked to insulin resistance
Fasting glucose Detects impaired fasting glucose and diabetes
HbA1c Estimates average blood glucose over about 3 months
Fasting insulin May reveal compensatory hyperinsulinemia before glucose becomes abnormal
HOMA-IR Uses fasting glucose and fasting insulin to estimate insulin resistance
Oral glucose tolerance test Detects impaired glucose tolerance and is used in pregnancy screening
Lipid panel High triglycerides and low HDL suggest insulin resistance
Blood pressure Hypertension is part of metabolic syndrome
Liver enzymes May suggest fatty liver disease
Skin exam Acanthosis nigricans and skin tags may suggest hyperinsulinemia

HOMA-IR

HOMA-IR, or homeostatic model assessment of insulin resistance, is a calculated estimate of insulin resistance using fasting glucose and fasting insulin. It is not perfect but may be useful in selected patients.

Insulin resistance calculator

Patients who want to estimate their risk may use an educational insulin resistance calculator. Online calculators are not a substitute for medical care, but they may help patients recognize risk factors and seek evaluation.

Treatment

Treatment for insulin resistance typically involves long-term lifestyle and medical strategies. The goal is to improve insulin sensitivity, reduce excess insulin demand, promote healthy weight loss, prevent progression to diabetes, and reduce cardiometabolic risk.

Treatment may include:

Lifestyle changes

Lifestyle changes that may improve insulin sensitivity include nutrition change, physical activity, weight loss, better sleep, and stress management.

Physical activity

Exercise improves insulin sensitivity because active muscles take up glucose more effectively. Both aerobic activity and resistance training are useful.

Helpful strategies include:

  • Walking
  • Post-meal walking
  • Resistance training
  • Strength training
  • Chair exercises
  • Low-impact exercise
  • Step goals
  • Reducing prolonged sitting

The CDC recommends at least 150 minutes of moderate-intensity aerobic activity weekly plus 2 days of muscle-strengthening activity for adults.Adult Activity: An Overview(link). Centers for Disease Control and Prevention.December 20, 2023.

Weight loss

Weight loss can improve insulin resistance, prediabetes, metabolic syndrome, PCOS-related metabolic risk, fatty liver disease, and sleep apnea risk.

The CDC describes the Diabetes Prevention Program lifestyle intervention as focusing on calorie reduction and increasing physical activity to at least 150 minutes weekly, and reports that losing 5% to 7% of body weight reduced type 2 diabetes incidence by 58% in the original study.Prevent Type 2 Diabetes: Talking to Your Patients About Lifestyle Change(link). Centers for Disease Control and Prevention.May 15, 2024.

Healthy diet

A diet for insulin resistance should reduce glycemic load, increase satiety, and fit the patient's real life. Many insulin-resistant patients do better with a lower-glycemic or lower-carbohydrate plan than with a high-carbohydrate, low-fat pattern.

Helpful dietary patterns may include:

A 2021 BMJ systematic review and meta-analysis of randomized trials found that low-glycemic-index or low-glycemic-load dietary patterns improved HbA1c and several cardiometabolic risk factors in people with diabetes."Effect of low glycaemic index or load dietary patterns on glycaemic control and cardiometabolic risk factors in diabetes: systematic review and meta-analysis of randomised controlled trials".BMJ.2021;374

n1651.PMID:34301841.PMC:8336013.

Stress management

Chronic stress can worsen eating patterns, sleep, cravings, and glucose regulation. Stress management may include:

  • Sleep routine improvement
  • Walking
  • Meditation
  • Deep breathing
  • Counseling when appropriate
  • Time-restricted work boundaries
  • Reduced late-night eating
  • Social support

Foods that may worsen insulin resistance

Foods that may worsen insulin resistance when eaten frequently or in large portions include:

  • Sugar-sweetened beverages
  • Fruit juice
  • Candy
  • Desserts
  • White bread
  • White rice
  • Sweet cereals
  • Pastries
  • Chips
  • Crackers
  • Large portions of pasta
  • Fried starches
  • Ultra-processed snack foods
  • High-sugar coffee drinks

Foods that may help

Foods that may help insulin-resistant patients feel full and reduce glycemic load include:

  • Eggs
  • Fish
  • Chicken
  • Turkey
  • Lean meat
  • Tofu
  • Tempeh
  • Paneer in measured portions
  • Greek yogurt without added sugar
  • Non-starchy vegetables
  • Leafy greens
  • Broccoli
  • Cauliflower
  • Cabbage
  • Zucchini
  • Mushrooms
  • Avocado
  • Olives
  • Nuts
  • Seeds
  • Olive oil

Low-carbohydrate and ketogenic diets

Low-carbohydrate diet and ketogenic diet approaches may help selected insulin-resistant patients by reducing glucose load, lowering insulin demand, improving appetite control, and supporting weight loss.

These diets should be medically supervised in patients with:

  • Diabetes medications
  • Pregnancy
  • Breastfeeding
  • Eating disorder history
  • Kidney disease
  • Liver disease
  • SGLT2 inhibitor use
  • Complex medical conditions

Medications

Medications may be used when lifestyle measures alone are not enough or when obesity-related disease is present.

Medication options may include:

Medication choice depends on medical history, pregnancy status, diabetes status, blood pressure, heart disease risk, psychiatric history, medication interactions, insurance coverage, and clinician judgment.

GLP-1 and Tirzepatide for insulin-resistant weight gain

GLP-1 weight loss injections and incretin-based medications can be useful for selected patients with obesity and insulin resistance because they may reduce hunger, improve satiety, lower food noise, improve weight loss, and improve metabolic risk markers.

Options may include:

The FDA approved Tirzepatide or Zepbound for chronic weight management in adults with obesity or overweight with at least one weight-related condition, in addition to reduced-calorie diet and increased physical activity.FDA Approves New Medication for Chronic Weight Management(link). U.S. Food and Drug Administration.November 8, 2023.

The FDA approved Semaglutide or Wegovy to reduce the risk of major adverse cardiovascular events in adults with established cardiovascular disease and either obesity or overweight.FDA Approves First Treatment to Reduce Risk of Serious Heart Problems Specifically in Adults with Obesity or Overweight(link). U.S. Food and Drug Administration.March 8, 2024.

Important pregnancy medication warning

Pregnant patients, patients trying to conceive, and breastfeeding patients should not start weight-loss medications without specialist guidance. GLP-1 medications and most prescription weight-loss medications are generally not used during pregnancy. Gestational diabetes should be managed by obstetrics, maternal-fetal medicine, endocrinology, diabetes education, or other qualified clinicians as appropriate.

Fantastic program. Truly a life changer.

“FANTASTIC program! Truly a life changer! The first several months I lost on average 3 pounds a week. I have now lost 87 pounds in 10 months and I'm still losing! I can say it feels almost effortless, for with the elimination of most carbs plus the medication I have ZERO cravings and minimal hunger. My cholesterol, blood pressure, and blood sugar have all returned to normal having previously been considerably elevated. I look and feel twenty years younger (I am 57.) Staff is friendly and supportive, and the science works. I did not think that I would be able to achieve such results, and certainly not in less than a year. I am amazed at my success, and I could not have done it without Dr. Tumpati and W8MD.”

Frequently asked questions

Can insulin resistance lead to gestational diabetes?

Yes. Insulin resistance can worsen during pregnancy, and pregnancy can reveal underlying subclinical insulin resistance as gestational diabetes.

Can insulin resistance lead to type 2 diabetes?

Yes. If insulin resistance is not addressed, the pancreas may eventually fail to produce enough insulin to keep blood glucose normal, leading to prediabetes and type 2 diabetes.

What does insulin do?

Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels and allows cells to use or store glucose.

How does insulin resistance present?

Some people have no symptoms. Others may have weight gain, abdominal obesity, sugar cravings, skin tags, acanthosis nigricans, PCOS symptoms, high triglycerides, or prediabetes.

What are the symptoms and signs of insulin resistance?

Common signs may include weight gain, upper-body or abdominal weight gain, sugar cravings, fatigue after meals, acanthosis nigricans, skin tags, high triglycerides, low HDL cholesterol, and irregular periods.

How do you know if you are insulin resistant?

A medical evaluation may include waist circumference, fasting glucose, HbA1c, fasting insulin, lipid panel, blood pressure, oral glucose tolerance testing, and an insulin resistance calculator such as HOMA-IR.

Can insulin resistance explain cravings for starchy foods?

Yes. Insulin resistance and high insulin levels can contribute to blood sugar fluctuations, hunger, and cravings for starchy or sugary foods.

Can insulin resistance be reversed?

Insulin resistance can often be improved and sometimes substantially reversed with weight loss, low-glycemic nutrition, physical activity, improved sleep, treatment of sleep apnea, and medications when appropriate.

Can insulin resistance lead to weight gain?

Yes. Insulin is an anabolic hormone, and high insulin levels can promote fat storage and make it harder for some patients to access stored fat between meals.

How common is insulin resistance?

Insulin resistance is very common, especially among people with obesity, abdominal weight gain, prediabetes, type 2 diabetes risk, PCOS, metabolic syndrome, and sleep apnea.

Did the old Food Guide Pyramid contribute to insulin resistance?

The former Food Guide Pyramid emphasized grains and low-fat eating, and many people interpreted it as permission to eat large amounts of starches and low-fat processed foods. This high-glycemic eating pattern may have worsened insulin resistance in susceptible individuals, especially when combined with sugar, refined flour, sedentary behavior, and excess calories.

What is metabolic starvation?

Metabolic starvation is an explanatory term used when high insulin levels make it difficult for the body to access stored fat, leading to hunger, cravings, fatigue, and difficulty losing weight despite having excess stored energy.

Can W8MD help with insulin resistance?

Yes. W8MD physicians have over 16 years of experience helping patients with insulin resistance-related weight gain, prediabetes, PCOS, metabolic syndrome, sleep apnea, and long-term weight management.

Conclusion

Insulin resistance is a common but under-recognized metabolic condition in which the body's cells do not respond normally to insulin. It can cause high insulin levels, weight gain, abdominal obesity, cravings, metabolic syndrome, PCOS, gestational diabetes, prediabetes, and type 2 diabetes. Because insulin resistance may exist for years before blood sugar becomes abnormal, early recognition is important. W8MD Weight Loss, Sleep and MedSpa physicians, with over 16 years of experience, can help patients identify and manage insulin resistance through evidence-based medical weight management, low-glycemic and low-carbohydrate nutrition, culturally customized meal planning, meal replacements, GLP-1 medications when appropriate, traditional weight-loss medications when appropriate, sleep apnea evaluation, exercise counseling, and long-term weight-loss maintenance.
