5 Key Metabolic Markers: What They Mean for Your Health

Metabolic health is a hot topic in today’s healthcare arena, and for good reason—only 12 percent of Americans are considered metabolically healthy, even among people who are not overweight. Metabolic health doesn’t always have a clear definition, but it is generally accepted as including normal levels of five measurable characteristics known as metabolic markers.

Metabolic markers are used by health professionals to gauge someone’s overall health. These markers include blood pressure, blood sugar, triglycerides, high-density lipoprotein and low-density lipoprotein cholesterol, and waist measurement.

So what makes these specific metrics so important for overall health? Read on to learn all about metabolic health markers and how to keep them in check.

Metabolic Health and Metabolic Syndrome

When metabolic health is compromised, it can lead to a wide range of health concerns and conditions. One of these conditions is known as metabolic syndrome. Metabolic syndrome refers to a cluster of physical conditions that can lead to an increased risk of heart disease, stroke, diabetes, and other chronic diseases.

Metabolic health markers are often used to determine if a patient has metabolic syndrome. You may have metabolic syndrome if you have three or more of the following: 

  • High fasting glucose
  • High cholesterol
  • High triglycerides
  • High blood pressure
  • High waist circumference

Let’s take a look at each of the individual markers of metabolic health and how to know whether or not they’re in the normal range.

1) Blood Glucose Levels

Blood glucose is one of the most important metabolic markers. Having blood sugar levels that are chronically higher or lower than normal or having a high glycemic variability can put you at a greater risk of metabolic disease and a number of chronic health conditions.

Fasting blood glucose is measured during a fasting state—meaning you haven’t had anything to eat or drink for at least eight hours. A normal fasting blood glucose is generally considered to be less than 100 mg/dL, according to the ADA, while higher levels could be a sign of prediabetes or diabetes.

Blood sugar that is too high is called hyperglycemia, and over time, chronically high levels can lead to type 2 diabetes mellitus, heart disease, stroke, nerve damage, fatty liver disease, kidney damage, and vision loss. Over time, it can also cause insulin resistance, which may cause changes in how your pancreas produces insulin and how your cells respond to insulin.

Blood sugar that is low is called hypoglycemia. Having frequent episodes of hypoglycemia can cause symptoms like brain fog, fatigue, lightheadedness, anxiety, and heart palpitations.

2) Cholesterol Levels

Cholesterol by itself is present in all the cells in your body, and is a type of fat that is essential for normal bodily functioning. Cholesterol includes substances in your body such as:

  • High-density lipoprotein (HDL) 
  • Low-density lipoprotein (LDL) 
  • Triglycerides

It’s worth noting that there is some ongoing debate as to what optimal cholesterol levels may be. Additionally, recent research has even suggested that very high HDL-C levels are associated with an increased risk of all-cause death and cardiovascular death among men but not in women in the general population free of coronary artery disease. More research is needed to better understand these associations. 

Cholesterol in and of itself is not considered good or bad. It is needed to help digest food, and to make hormones and some vitamins. Your body makes all the cholesterol it needs, but some dietary factors like saturated fat have been shown to increase cholesterol levels. However, the link between saturated fat and heart disease is not so straightforward

Your liver makes most of the HDL and LDL that you need. In the body, HDL absorbs the cholesterol in your blood and takes it back to your liver.  LDL cholesterol is also needed to carry your cholesterol to our muscle, adrenal glands, gonads and adipose tissues. 

However, levels of HDL cholesterol that are too low and levels of LDL cholesterol that are too high can be considered cardiovascular risk factors and may lead to a higher risk of having a heart attack or stroke. Factors like a lack of exercise, high stress, and excessive smoking can lead to high cholesterol levels.

3) Triglycerides

Having elevated triglycerides is another factor linked to cardiovascular disease. Triglycerides may become elevated as a result of dietary factors such as high intake of sugar and fat. There are some chronic conditions that can also cause higher than normal triglycerides such as kidney disease, liver disease, diabetes, thyroid disease, and obesity.

A normal triglyceride level for adults is considered to be less than 150 mg/dL. Having higher than normal triglycerides can increase risk for heart disease and metabolic syndrome.

4) Blood Pressure

blood pressure ranges

Your blood pressure is a measurement of the force your arteries use to pump blood throughout your body. Your systolic number (top number) represents the force on the artery walls when your heart beats and pumps the blood into your arteries. The diastolic number (bottom number) represents the pressure in your arteries when your heart is at rest between heartbeats.

If your blood pressure is consistently higher than 120/80, you’re at risk of developing stiff arteries, leading to high blood pressure, or hypertension. Arteries can become stiff due to several reasons, including:

  • Genetics
  • Dietary factors 
  • Physical activity 
  • High stress levels

There are often no symptoms of high blood pressure so it’s important to monitor your blood pressure regularly. High blood pressure can increase your risk of developing heart disease, having a stroke, developing hardening of your arteries which leads to decreased blood flow, and even dementia.  

On the other hand, low blood pressure or hypotension does have symptoms and can indicate other health issues such as neuroendocrine conditions, heart problems, and even low blood sugar. Symptoms of hypotension can include dizziness, lightheadedness, fainting, nausea, and trouble concentrating. 

 5) Waist Circumference

normal waist circumference ranges

The last marker of metabolic health is your waist circumference. Your waist circumference is the measurement taken around your abdomen at the level of your belly button. Similar to the idea of a body mass index (BMI) test, this measurement can let you know if you may be generally at risk, though more individualized assessment may be needed to confirm.

Having excess fat around your abdominal area may be more dangerous to your health than having fat in other areas. This is because this “visceral fat” is metabolically active and increases your risk of heart disease, high blood pressure, diabetes, high cholesterol, and sleep apnea.

A normal waist circumference is 35 inches for non-pregnant women and 40 inches for men. If your waist circumference is higher than this, you’re at risk.  

Expert Tips for Managing and Monitoring Metabolic Markers

Your metabolic biomarkers have significant implications for your metabolic health, and these metabolic markers are connected, meaning that if one of your markers is abnormal, this may be a predictor of having other markers that are abnormal.

Luckily, it is possible to improve your markers and decrease your risk of metabolic syndrome and other health conditions with certain lifestyle changes and guidance from healthcare professionals and qualified nutritionists.

Choose Reliable Testing Methods

It’s important to choose reliable testing tools when you’re evaluating your metabolic markers. One common method to assess metabolic health involves blood tests that measure various biomarkers, such as glucose levels, lipid profiles, and insulin sensitivity

Another way to stay on top of your metabolic health is through a continuous glucose monitor. A CGM allows you to see how your blood glucose levels fluctuate in real-time throughout the day. This can provide valuable insight regarding what you eat, how exercise impacts your glucose and even how your glucose changes while you sleep.

With Nutrisense, you can gain access to CGM devices, an intuitive mobile app for tracking your data, and expert guidance from nutritionists to help you better understand your metabolic health and customize your diet and lifestyle approach. 

Eat a Balanced Diet

Eating a healthy diet is one factor that can help maintain healthy glucose levels and support weight loss or weight management for better metabolic health. While dietary needs can vary greatly from person to person, working to limit the amount of ultra-processed foods and high glycemic carbohydrates like sugar and refined carbs in your diet is a great way to get started. Focus on incorporating whole foods like fiber-rich fruits, vegetables, healthy fats, and lean proteins in your diet. 

Get Appropriate Levels of Exercise

Increasing your physical activity can also make a big difference for your metabolic health. Adequate exercise can lower all five of your metabolic markers, helping you to maintain a healthy, normal weight, regulate your glucose levels, and more. Aiming for at least 30 minutes of moderate-intensity exercise most days of the week may be a good goal for many, though individual tolerance and needs should always be assessed when building the ideal exercise program. 

Practice Good Sleep Hygiene

Practicing good sleep hygiene can also help optimize your blood pressure, blood sugar levels, and other metabolic markers. To obtain these benefits, avoid using devices that emit blue light at least an hour before bed, try to go to bed at the same time each night and avoid drinking caffeinated or alcoholic beverages before bed or more generally if you are especially sensitive to these.

Your diet may also impact your sleep in a number of ways worth considering. 

Manage Stress Effectively

Chronic stress can negatively affect all areas of your metabolic health. This type of stress can result in significant negative health effects that impact every aspect of health and function, including glucose regulation, lipid levels, blood pressure, and even weight. 

Chronic stress can come in many forms, including ongoing nutrient imbalances, improper fueling for workouts, high levels of psychosocial pressure, and lack of sleep. Practicing stress-reduction techniques like yoga, meditation, or deep breathing exercises can help manage certain types of stress more effectively.
