July 2024 · 10 minute read

You may be trying to boost your metabolic health, but it can be hard to tell if things are truly improving. In this article, we will talk about four markers you should keep track of to make sure you’re headed in the right direction.

Your metabolic health refers to the different systems in your body that naturally keep you healthy. It includes your cardiovascular system, blood glucose management, metabolism, and kidney health. 

Different blood tests and body measurements can help assess your metabolic health status. In the article, you’ll learn what to look for and how to improve your results.  

1. Waist Circumference

Your waist circumference is measured with a classic tape measure. Some doctors will check and update your measurement at your annual check-up, but it varies per physician. You can easily do this assessment at home. 

Why Does Waist Circumference Matter For Metabolic Health?

A change in your waist circumference can be a precursor that your metabolic health could be changing. That is because the weight and visceral fatty tissues carried around the middle of your body can be hormonally active. 

Visceral fatty tissues lie deep under the skin and wrap around your organs.¹ Excess visceral fat exacerbates inflammatory responses and contributes to poor metabolic health. 

What Are The Target Numbers?

Different target ranges for ideal waist circumferences exist for different genders.²

What Are the Health Risks? 

A high waist circumference increases your risk of developing: 

What Can Make Your Waist Circumference Increase? 

The most common reason why your waist circumference would increase is excessive calorie intake, combined with low energy output (or physical activity).¹

Another factor to consider is the genetic disposition of how your body carries weight. If your relatives carry weight on their abdomen your body will likely do the same. Your hormones can also influence how you carry weight. Women tend to be more susceptible to changes in weight related to hormonal fluctuations across the lifespan.  

What Can You Do To Improve Waist Circumference?

The best approach to managing your waist is to follow a nutritious balanced diet. To do this: 

You can not control where your body will store fat. But, you can control your food choices throughout the day. 

2. Blood Glucose Levels

Your blood glucose levels can indicate how efficiently your body is able to clear sugars out of your bloodstream.  

What Are The Targets For Blood Glucose Levels? 

The current CDC guidelines for blood sugars indicate:⁴

What Are The Risks Of High Blood Sugars? 

High blood sugars can damage vessels that supply blood to vital organs.⁵ This can increase your risk of: 

What Makes Blood Glucose Levels Rise? 

A mix of lifestyle and genetic factors can contribute to high blood glucose levels: 

It is unlikely that one single factor will influence your blood sugars. All of these elements have compounding effects on your glucose levels.  

What Can You Do To Improve Blood Glucose Levels?

Start by focusing on your diet and physical activity: 

Lifestyle changes can have a great influence on your blood sugars. Eating less white sugar can be a helpful place to start, but following the other actionable steps can help you achieve even better results. 

3. Triglycerides

Your triglycerides are a type of blood cholesterol. Your triglyceride numbers can only be measured in a formal blood test completed at a lab. 

Why Do Triglycerides Matter For Metabolic Health? 

Your triglycerides are packaged envelopes of glucose that have been converted into fat. The energy-dense molecules float in your bloodstream and are readily available in case your body needs fuel. 

Exercise and movement will help you use the fuel. But, if you are sedentary and consume more calories than you need, your triglyceride levels can rise beyond healthy limits. 

Biology and genetics play a significant role in lipid metabolization, too. It is common for people who have a larger waist circumference to also have higher levels of triglycerides.⁶

What Are The Target Numbers For Triglycerides?

The target range for triglyceride levels are:⁷ 

Risk of elevated triglycerides 

Elevated triglyceride levels increase your risk of the following conditions:⁸

What Makes Triglycerides Increase?

A mixture of poor diet and lifestyle choices can raise your triglyceride levels. Some examples include:⁸ 

What Can You Do To Improve Triglyceride Levels?

If you drink alcohol, consider decreasing your intake. Long-term moderation is recommended to maintain healthy triglyceride levels. You can also: 

The Mediterranean diet is rich in vegetables, healthy unsaturated fats, and can help decrease your triglyceride levels. Learn more about how to follow this diet to support your triglyceride levels and other metabolic health markers.

4. LDL/HDL Cholesterol Levels

Your blood cholesterol levels are called serum lipids. Triglycerides are part of your lipids, and so are high-density lipoproteins (HDL) and low-density lipoproteins (LDL).

Why Do LDL And HDL Matter To Metabolic Health?

For a long time, your blood cholesterol levels were measured and used to assess your risk of cardiovascular disease. 

Helping people move towards a lower LDL score was a priority because LDL cholesterol contributes to the hardening of your arteries and plaque build-up, also known as atherosclerosis.¹⁰ Hardened arteries increase your risk of blockages, stroke, and decreased blood flow to vital organs. 

HDL was believed to be the healthy form of blood cholesterol that might have heart-protecting benefits, but research teams are questioning if cholesterol levels are a reliable indicator of cardiovascular health.¹¹

The current leading organizations in the field stand by the recommendation that LDL should remain low, while HDL should be high.¹² 

What Are The Target Numbers for LDL and HDL cholesterol?

The ranges for cholesterol will change across your lifetime:¹³

Your cholesterol can give your doctor a snapshot of your health. They should use your blood test information to complete a cardiovascular disease risk calculator to better interpret your numbers. 

The risk formula is more comprehensive because it captures your family history, smoking habits, age, gender, other diagnoses, and blood pressure.¹⁴  

What Makes Cholesterol Levels Unhealthy? 

According to the American Heart Association, several elements within your lifestyle can lead to rising cholesterol numbers: 

What Can You Do To Improve Cholesterol Levels?

Similar to the other markers, you should prioritize lifestyle changes first: 

Any changes or trends in your numbers over time can provide deeper insight into how your health is evolving. 

5. Blood Pressure

Your blood pressure measures the force and effort your heart exerts to pump blood into your arteries.

Why Does Blood Pressure Matter For Metabolic Health?

It is normal for your blood pressure to fluctuate throughout the day. However, when blood pressure elevates and stays high, it puts strain on your vessels and your heart. 

High blood pressure, known as hypertension, can increase your risk of heart disease and stroke. The CDC estimates that as of 2020, 47% of Americans have hypertension.¹⁷

What Are The Target Numbers For Blood Pressure? 

A blood pressure reading is presented as a fraction.¹⁸ The top number is systolic and should be below 120mmHg. It captures the pressure in your arteries as your heart beats. 

The bottom number is diastolic and should be below 80mmHg. It refers to the pressure in the heart as it rests between beats. During this time the atriums will fill back up with blood. At the next beat, blood is pushed into the arteries and the cycle continues. 

What Makes Blood Pressure Rise To Unhealthy Levels? 

Many people don’t realize they have high blood pressure until they check their numbers. Factors that can contribute to high blood pressure include: 

What Can You Do To Improve Blood Pressure? 

To improve blood pressure you could:¹⁹

Caffeinated products can temporarily raise your blood pressure. If you are checking your numbers at home, try to measure your levels before drinking your daily cup of coffee. 

What Explains the Low Rates of Metabolic Health in Americans?

Compared to other parts of the world, the low metabolic health rates persist across America. There are several reasons that contribute to these low rates: 

A study published In 2019 indicated that only 19.9% of Americans were Metabolically healthy²⁰. High blood pressure plagues half the population and needs to be prioritized.Unmanaged hypertension can lead to heart disease and stroke, which both have high mortality rates in the US.¹⁶ 

How to Begin Improving Your Markers of Metabolic Health

There is a ton of information in this post and your brain may be swimming trying to figure out where to start. The good news is that the changes you make to target one area of your health will benefit many others too. 

More physical activity helps to lower blood sugars, blood pressure, and cholesterol. If you are not already active, start by focusing on this area of your health. 

If you are already active, focus on increasing your intake of fiber-rich foods. Include whole grains, vegetables, fruits, nuts, and legumes throughout your week.

Quitting smoking is one of the best choices you can make for your metabolic health. If you need support consider reaching out to your health care team. 

Although it can be tempting to go on a ‘health-kick’ overnight and change everything about your life, try to pursue a more sustainable approach. Your healthy habits should be repeatable and fit in easily with your lifestyle.
