When it comes to assessing heart health risk, waist circumference is a simple yet often overlooked tool. 

Unlike body mass index (BMI), which provides a general measurement of your body weight compared to your height, waist circumference specifically evaluates abdominal (visceral) fat that surrounds your vital organs. 

Research consistently shows that a larger waistline increases the risk of heart disease, high blood pressure, and type 2 diabetes, making it an essential factor in evaluating overall cardiovascular health.

Waist Circumference: What is it and Why Does it Matter?

Having extra visceral fat matters because this is the type of fat most closely linked to cardiovascular risk. Carrying extra fat around your midsection is called central obesity and contributes to inflammation, insulin resistance, and metabolic disorders.

Optimal Measurements

Because men and women tend to store fat differently, the high-risk waist circumference cutoffs differ. The optimal waist circumference measurements are:

• Men: Less than 40 inches (102 cm)
• Women: Less than 35 inches (88 cm)

Exceeding these measurements is associated with a higher risk of heart disease, type 2 diabetes, and metabolic syndrome. 

Note that these measurements aren’t necessarily a one-size-fits-all for every man and woman. There are unique differences among all of us, such as how ethnicity can influence waist measurements—which we’ll discuss more below.

How to Measure Waist Circumference Correctly

Measuring your waist circumference is a simple thing you can do in the comfort of your own home. However, it’s important to measure it correctly by following these steps: 

1. Stand fully upright and relax your abdomen.
2. Place a flexible measuring tape straight around your bare waist, just above your hip bones (belly button level). Make sure it’s not higher up on your back than front.
3. Ensure that your measuring tape is snug but isn’t compressing your skin (and that you’re not “sucking in” or holding your breath).
4. Take the measurement after a normal exhalation. 

To get the most accurate measurement, it’s best to take it in the morning before eating or drinking and after using the restroom. It can also be helpful to measure without clothing on so these layers don’t get in the way of the tape.

Finally, if your waist circumference measurement is higher than standard, I recommend measuring it every week to track changes.

Waist Circumference and Cardiovascular Disease

Unlike subcutaneous fat, which sits just beneath your skin, visceral fat (indicated by your waist circumference) is metabolically active and contributes to chronic inflammation, insulin resistance, and an increased risk of high blood pressure, dyslipidemia, and type 2 diabetes. These factors collectively raise your likelihood of developing heart disease and stroke.

Studies show that larger waists are strongly linked to cardiovascular disease risk, independent of BMI. 

For example, a 2017 study found that even among individuals with a “normal” BMI, those with excess abdominal fat had a significantly higher risk of heart attacks and premature death. 

Research by the American Heart Association concurs—experts recommend that waist measurements and BMI should be taken during regular wellness visits to help assess a higher risk of heart disease even in healthy-weight individuals. 

Differences Among Gender and Ethnicities, Explained

Men are more likely to store fat in the abdominal region, making them particularly prone to visceral fat accumulation and its associated metabolic risks. Women, especially before menopause, tend to store more fat in the hips and thighs due to the protective effects of estrogen. 

However, postmenopausal women often experience a shift in fat distribution toward the abdomen, increasing their cardiovascular risk. I am on the medical advisory board of the Menopause Foundation and this is something that comes up frequently. 

Waist circumference cutoffs for cardiovascular risk can also vary by ethnicity due to differences in body fat distribution and metabolic risk. 

For example, research shows that Asians, South Asians, and Hispanics tend to accumulate visceral fat at lower BMI levels, making them more prone to metabolic disorders like type 2 diabetes and heart disease even with a smaller waist. 

As a result, organizations like the International Diabetes Federation (IDF) recommend lower waist circumference thresholds for certain populations, such as <35 inches (90 cm) for Asian men and <31.5 inches (80 cm) for Asian women. 

Similarly, Black individuals may have a lower proportion of visceral fat compared to other groups at the same waist circumference but may be more likely to be obese, potentially altering relative cardiovascular risk. 

These differences highlight the importance of considering gender and ethnicity when assessing abdominal fat and heart health.

Strategies to Reduce Waist Circumference for Better Heart Health

Reducing waist measurements isn’t just about losing weight—it’s about targeting visceral fat, improving metabolic health, and lowering your cardiovascular risk. 

A combination of science-based nutrition, regular exercise, and other lifestyle adjustments can help reduce abdominal fat and improve your heart health.

Nutrition Modifications

Instead of focusing solely on cutting calories, prioritizing nutrient quality helps address the underlying inflammation and insulin resistance associated with central obesity. Here are some simple ways to improve your nutrition: 

• Emphasize fiber, healthy fats, and lean proteins to regulate blood sugar, promote satiety, and help maintain lean muscle mass. 
• Limit refined carbs, saturated fats, and added sugars found in ultra-processed foods and sugary drinks, as these can contribute to abdominal fat storage and worsen insulin resistance.
• Avoid extreme calorie restriction, as this may promote initial weight loss but doesn’t address metabolic drivers of visceral fat.

Regular Exercise

Physical activity is essential for reducing waist size and improving heart health. A combination of aerobic and resistance training is the most effective approach:

• Resistance exercises like weightlifting, bodyweight exercises, and bands help build muscle, which increases resting metabolism and fat burning.
• Engage in aerobic exercise, as activities like brisk walking, cycling, swimming, or high-intensity interval training (HIIT) burn visceral fat and improve insulin sensitivity.
• Prioritize consistency over intensity, as even getting moderate activity for 30 minutes a day can significantly reduce waist size and improve cardiovascular markers.

Other Lifestyle Factors

Beyond diet and exercise, your other everyday habits can either help or hurt your efforts to lower abdominal fat. Here are some things to consider:

• Chronic stress leads to elevated cortisol levels and promotes fat storage around the midsection, so implementing regular practices like meditation and deep breathing can help regulate your stress responses.
• Get 7-9 hours of sleep per night as poor sleep disrupts appetite-regulating hormones and can make healthy weight management challenging. 
• Reduce intake of alcohol, which is high in empty calories and can contribute to visceral fat.

Client Success Story

A 34-year-old woman with a history of polycystic ovary syndrome (PCOS) came to see me due to resistant hypertension—her blood pressure was high and unresponsive to three different medications. She was following a ketogenic diet to manage insulin resistance, but it wasn’t improving her blood sugar, weight, or blood pressure levels.

We worked closely together in my VIP program, where over 4 months, she lost 10 inches and 24 lbs. In just 3 weeks, her blood pressure normalized to an average of 115/75mmHg—and she was able to stop all of her blood pressure medications.

When you approach dieting with a deprivation mindset, it can hinder your ability to achieve long-term health goals. By focusing on a well-balanced, nutrient-rich diet, we addressed the entire picture of her health—improving everything from waist circumference to blood pressure, cholesterol, and blood sugar levels.

Your Waist is a Simple Marker of Heart Health

Maintaining a healthy waist circumference is a crucial step in reducing your cardiovascular risk and improving overall health. If your waist size is higher than standard, focus on things you can control, including nutritional quality, exercise, stress, and sleep. 

Small, sustainable changes can lead to significant improvements, making waist circumference a valuable metric for assessing and maintaining cardiovascular well-being.
