A Metabolic Syndrome Guide: Diet, Foods to Eat/Avoid + Tips

Publish date: 2024-08-30

Metabolic health is important for overall health and well-being. It is your body’s ability to properly digest, process, and utilize nutrients from the foods you eat and turn them into energy. When metabolism isn’t functioning properly, this can lead to an array of health problems that, when combined, are referred to as metabolic syndrome. 

What is Metabolic Syndrome?

Metabolic syndrome, sometimes called syndrome X or MetS, is a condition that increases the risk of heart attacks, stroke, and type 2 diabetes. 

According to the American Heart Association (AHA), metabolic syndrome is when you have three or more of the following conditions1:

Who is at Higher Risk for Metabolic Syndrome?

Some people have a higher risk of developing metabolic syndrome. Genetics may play a role in this, so your risk may be greater if you have family members who have it or meet any of its criteria. Insulin resistance and being overweight may also contribute to risk.2 

Other lifestyle factors like being physically inactive, eating a poor diet, not getting enough sleep, and chronic stress may also increase the risk of developing metabolic syndrome.

Metabolic Syndrome Common Symptoms and Treatment 

Metabolic syndrome is often called a "silent" condition because people often don’t have noticeable symptoms. However, other health conditions can indicate metabolic syndrome, including high blood pressure, high triglycerides, and being overweight. People with insulin resistance may have acanthosis nigricans, a darkening of the skin on the back of the neck, in the armpits, and under the breasts.2

Your doctor may diagnose you with metabolic syndrome if you have the following:

There are several things a doctor may recommend for the treatment of metabolic syndrome. These recommendations will be based on age, overall health, other comorbid conditions, how well medications and treatments can be tolerated, and most importantly, the preference and opinion of the patient. 

Some of these treatment options include:

When metabolic syndrome goes untreated, type 2 diabetes may occur. Almost everyone who has metabolic syndrome also has insulin resistance. The body produces insulin to transport sugar (glucose) into cells for energy. Having excess body weight interferes with the way cells respond to insulin. The body must then produce more insulin to try to overcome the resistance, and when the body cannot produce enough, the blood sugar level increases. 

Other possible complications of untreated metabolic syndrome include heart disease, stroke, polycystic ovarian syndrome (PCOS), fatty liver, cholesterol gallstones, asthma, sleep problems, and some forms of cancer.2

Is It Hard to Lose Weight with Metabolic Syndrome?

Weight loss is difficult for many people but can be even harder for those with metabolic syndrome. Insulin resistance interferes with the way the body processes glucose. Metabolic syndrome can also cause hormonal changes and altered metabolism, which can interfere with weight loss. 

Lifestyle changes, including better nutrition and frequent physical exercise, can help to improve metabolic health, increase insulin sensitivity, and promote weight loss. It may require more effort and maybe even some help from medication or surgery, but weight loss can be achieved even with metabolic syndrome.3 

Metabolic Syndrome Diet: 6 Foods You Should Eat

Making a few changes to your diet can help improve the symptoms of metabolic syndrome. Adding more of the following foods can help manage cholesterol, improve insulin sensitivity, and help with weight management.4 

1. Foods rich in fiber 

High-fiber foods help regulate blood sugar levels by slowing digestion and delaying the release of sugar into the bloodstream. 

Fiber also promotes healthy cholesterol levels, lowering LDL and increasing HDL cholesterol. Fiber increases feelings of fullness and satiety, which may help reduce overall caloric intake and promote weight loss.5

Foods high in fiber include:

2. Plenty of fruits and vegetables 

Fruits and vegetables are low in calories but high in fiber and nutrients, which can help with weight management. They are also high in vitamins, minerals, and antioxidants, which may help reduce inflammation, improve blood pressure, and increase insulin sensitivity. These nutritious foods are also low in fat, which can help reduce saturated fat intake and the risk of heart disease.4 

3. Whole grains

Whole grains are high in fiber, vitamins, and minerals, all of which promote heart health, lower cholesterol, and manage blood sugars.4,5 

Examples of whole grains:

4. Omega-3 Fatty acids 

Research shows that consuming omega-3s can lower triglyceride levels, reduce inflammation, and improve insulin sensitivity, which is important for controlling blood sugar levels.4

Foods containing omega-3 fatty acids include:

5. Potassium 

Potassium-rich foods help reduce blood pressure and control blood sugar. When potassium levels are too low, the body may make less insulin. That could lead to high blood sugar. 

Studies show that people with low potassium levels release less insulin, have higher blood sugar levels, and are more likely to get type 2 diabetes than those with normal potassium levels.6

Sources of potassium include:

6. Lean sources of protein 

Lean proteins can help regulate blood sugar levels, lower inflammation, and support weight loss.4

Sources of lean protein include:

Metabolic Syndrome Supplements

There are many supplements available that may help manage the symptoms of metabolic syndrome. Supplements should not be used to replace regular exercise, a balanced diet, and stress management techniques. Supplements should be used in conjunction with healthy lifestyle habits.7 

The following supplements could benefit metabolic syndrome: 

  • Omega-3 Fatty Acids: Omega-3 fatty acids can help improve blood lipid levels, reduce inflammation, and lower blood pressure. 
  • Magnesium: Magnesium plays a role in regulating blood sugar levels and blood pressure. 
  • Vitamin D: Low vitamin D levels have been associated with an increased risk of metabolic syndrome. Sunlight is the best source of vitamin D, but supplements are also available for those who are deficient.
  • Probiotics: Probiotics are beneficial bacteria that can help to improve gut health and reduce inflammation. Some studies have shown that probiotics may help to improve blood sugar levels and reduce blood pressure in people with metabolic syndrome.10
  • Fiber: Fiber can help to lower blood sugar levels, reduce cholesterol levels, and promote weight loss. 

    • Always talk to your healthcare provider before starting any new supplements, especially if you are taking medication or have a pre-existing medical condition.

    6 Foods to Avoid if You Have Metabolic Syndrome

    1. Foods with added sugar

    The Dietary Guidelines for Americans recommend limiting added sugar intake to less than 10 percent of daily calorie intake. Excessive consumption of added sugars can increase the risk of insulin resistance, diabetes, heart disease, and other metabolic disorders.8

    Limit these sugar-containing foods:

    2. Saturated fat

    Too much saturated can lead to elevated cholesterol and triglycerides. Elevated cholesterol levels are one of the hallmarks of metabolic syndrome. If you have metabolic syndrome, you may want to limit or avoid foods high in saturated fats. 

    Foods high in saturated fats include: 

    3. Trans fats

    Trans fats have been shown to increase LDL cholesterol and decrease HDL cholesterol, which can increase the risk of developing heart disease. Whether you have metabolic syndrome or want to prevent it, avoid trans fats and choose healthier alternatives. 

    Food labels may not list trans fats directly, so it's important to read the ingredient list and look for partially hydrogenated oils, a source of trans fats.

    Sources of trans fats include:

    4. Alcohol

    Excessive alcohol intake can have a negative impact on anyone’s health, but people with metabolic syndrome should be especially mindful of their alcohol intake. Excessive alcohol consumption can lead to unwanted weight gain, high blood pressure, increased insulin resistance, fatty liver disease, and abnormal lipid levels. 

    5. High-sodium foods 

    People with metabolic syndrome should limit their sodium intake because consuming too much sodium may increase blood pressure and the risk of heart disease. 

    When you have metabolic syndrome and consume too much sodium, your body holds onto more water to maintain the right balance of electrolytes in the blood. This extra water increases blood volume, which then increases blood pressure. High blood pressure often damages the arterial walls, leading to a higher risk of heart disease and stroke. It can also harm the kidneys.

    The American Heart Association recommends that people with metabolic syndrome limit their sodium intake to no more than 1,500 milligrams per day, which is about 2/3 of a teaspoon of salt.1

    Many processed foods, such as canned soups, frozen dinners, and packaged snacks, are high in sodium. Pay attention to labels and opt for “no salt added” or low-sodium varieties. 

    6. Sugar-sweetened beverages

    Excessive consumption of added sugars can increase insulin resistance and the risk of diabetes, heart disease, and other metabolic disorders. If you have metabolic syndrome, avoid sugar-sweetened beverages like soda, sports drinks, juice, and sugary coffee drinks.

    Dietary Recommendations for Metabolic Syndrome 

    A comprehensive review of scientific evidence suggests that the Mediterranean diet or the DASH diet (Dietary Approaches to Stop Hypertension) are the best eating patterns for the management and prevention of metabolic syndrome.9

    The Mediterranean diet is a plant-based diet characterized by a high intake of vegetables, including leafy green vegetables, fruits, whole-grain cereals, pulses, legumes, nuts, and extra virgin (cold pressed) olive oil (EVOO) as the main source of fat. This diet also includes moderate consumption of fish and poultry and low consumption of red meat, butter, sweets, pastries, and soft drinks. The Mediterranean diet provides 35 to 45 percent of total daily energy intake from fat, about 15 percent from protein, and 40 to 45 percent energy from carbohydrates.9

    The DASH diet promotes a high intake of vegetables, fruits, whole grains, low- or fat-free dairy products, legumes, and nuts while limiting the intake of red meat and sugar-sweetened beverages. 

    The DASH diet is relatively low-fat and especially low in saturated fats and dietary cholesterol (approximately 150 mg/d). Sodium intake is limited to 1500 to 2300 mg/day. The DASH diet recommends high intakes of fiber (more than 30g per day), potassium, magnesium, and calcium.9

    Similarities between the Mediterranean and DASH diets include an emphasis on plant-based foods such as fruits, vegetables, whole grains, legumes, and nuts. They both limit the intake of red meat and saturated fat. 

    Tips to Incorporate a Metabolic Syndrome Diet

    Small changes have a big impact over time and tend to be more sustainable long term. Start by incorporating one or two of these tips into your daily routine and gradually add more as you feel more confident.

    How to Prevent Metabolic Syndrome

    Some risk factors for metabolic syndrome, like age or genetics, cannot be changed. However, you can modify lifestyle behaviors. Maintaining a weight that is appropriate for you, exercising regularly, eating a healthy diet, managing stress, getting enough sleep, not smoking, and limiting alcohol intake can all help to prevent metabolic syndrome.2
