Assess your metabolic syndrome risk using the NCEP ATP III criteria. Enter your waist circumference, triglycerides, HDL cholesterol, blood pressure, and fasting glucose to see how many of the five diagnostic criteria you meet.
Measure at the narrowest point, usually just above the navel
Systolic (top)
Diastolic (bottom)
Measured after at least 8 hours of fasting
Metabolic syndrome is diagnosed when 3 or more of 5 criteria are met: elevated waist circumference, elevated triglycerides, low HDL cholesterol, elevated blood pressure, and elevated fasting glucose. These values are typically found on routine blood work.

Metabolic syndrome is not a single disease but rather a cluster of five interconnected metabolic abnormalities that dramatically increase your risk of cardiovascular disease, type 2 diabetes, and stroke. According to the National Cholesterol Education Program's Adult Treatment Panel III (NCEP ATP III), a person is diagnosed with metabolic syndrome when they meet 3 or more of the following five criteria.
The condition affects approximately one-third of adults in the United States and its prevalence is rising globally. The good news is that metabolic syndrome is largely driven by lifestyle factors and can often be reversed through diet, exercise, and weight management.
Each criterion targets a different aspect of metabolic health. Meeting any single criterion indicates a risk factor worth addressing, but the combination of three or more creates a compounding effect on disease risk.
Greater than 102 cm (40 inches) for men or 88 cm (35 inches) for women. Abdominal obesity is the most visible marker of metabolic syndrome and is strongly correlated with visceral fat that surrounds internal organs.
150 mg/dL (1.7 mmol/L) or higher. Triglycerides are a type of fat in the blood. High levels are often linked to diets high in refined carbohydrates and sugars, excessive alcohol intake, and physical inactivity.
Less than 40 mg/dL (1.03 mmol/L) for men or 50 mg/dL (1.29 mmol/L) for women. HDL is the “good” cholesterol that helps remove other forms of cholesterol from the bloodstream. Low HDL is a strong independent risk factor for heart disease.
130/85 mmHg or higher (systolic or diastolic). Elevated blood pressure forces the heart to work harder and damages arterial walls over time, contributing to atherosclerosis and increasing the risk of heart attack and stroke.
100 mg/dL (5.6 mmol/L) or higher. This indicates impaired fasting glucose or insulin resistance, meaning your body is struggling to regulate blood sugar effectively. This is often a precursor to type 2 diabetes.
Having metabolic syndrome significantly increases your risk for several serious health conditions. The combined effect of the five criteria is greater than the sum of its parts — each additional criterion met amplifies overall risk.
People with metabolic syndrome have a 2x higher risk of developing cardiovascular disease. The combination of high blood pressure, dyslipidemia, and insulin resistance accelerates atherosclerosis.
Metabolic syndrome increases diabetes risk by 5x. Insulin resistance and elevated fasting glucose are early warning signs that can progress to full type 2 diabetes without intervention.
The elevated blood pressure and arterial damage associated with metabolic syndrome significantly increase stroke risk. Managing blood pressure is one of the most impactful steps you can take.
Metabolic syndrome is closely linked to non-alcoholic fatty liver disease (NAFLD), where excess fat accumulates in the liver. This can progress to inflammation and liver damage.
The most effective approach targets multiple risk factors simultaneously through lifestyle changes. Research shows that even modest improvements can move you from a metabolic syndrome diagnosis to a healthier metabolic profile.
Aim for at least 150 minutes of moderate-intensity exercise per week. Both aerobic exercise and resistance training improve insulin sensitivity, lower blood pressure, raise HDL, and reduce waist circumference.
Focus on whole foods, vegetables, lean proteins, and healthy fats. The Mediterranean and DASH diets have strong evidence for improving metabolic syndrome markers. Limit added sugars and refined carbohydrates.
Losing just 5–10% of body weight can significantly improve all five metabolic syndrome criteria. Focus on sustainable calorie reduction rather than extreme diets for lasting results.
Poor sleep and chronic stress elevate cortisol, promote insulin resistance, and increase abdominal fat storage. Aim for 7–9 hours of quality sleep and incorporate stress management practices.
Metabolic syndrome is a cluster of five interconnected conditions — elevated waist circumference, high triglycerides, low HDL cholesterol, high blood pressure, and elevated fasting glucose — that together significantly increase the risk of heart disease, stroke, and type 2 diabetes. It is diagnosed when 3 or more criteria are met.
The NCEP ATP III criteria are: (1) Waist circumference >102 cm (40 in) for men or >88 cm (35 in) for women; (2) Triglycerides ≥150 mg/dL; (3) HDL cholesterol <40 mg/dL for men or <50 mg/dL for women; (4) Blood pressure ≥130/85 mmHg; and (5) Fasting glucose ≥100 mg/dL.
Metabolic syndrome affects roughly one-third of adults in the United States. Prevalence increases with age, affecting nearly 50% of adults over age 60. Rates are rising globally due to increasing obesity and sedentary lifestyles.
Yes, metabolic syndrome can often be reversed through lifestyle changes. Regular physical activity (150+ minutes per week), weight loss of 5–10% of body weight, a diet rich in whole foods and healthy fats, stress management, and adequate sleep can all improve or normalize the individual risk factors.
You need a fasting lipid panel (which measures triglycerides and HDL cholesterol) and a fasting blood glucose test. Blood pressure is measured with a standard cuff, and waist circumference is measured with a tape measure. These are all part of routine health check-ups.
Insulin resistance is one component of metabolic syndrome, specifically related to elevated fasting glucose. Metabolic syndrome is a broader diagnosis that includes insulin resistance along with abdominal obesity, dyslipidemia (high triglycerides and low HDL), and hypertension.
