Metabolic and metabolism testing are ways to check if your metabolism works as it should. This can help you optimize your fitness, nutrition, and weight loss goals.

Whether you’re an athlete aiming to optimize performance, a fitness enthusiast on a weight loss journey, or someone seeking to improve overall health and well-being, metabolic testing is a game-changer that can take your progress to new heights.

So, fasten your seat belts, and let’s deep dive into the world of metabolic testing, enabling you to understand your body like never before.

Metabolic testing is an assessment that delves into the way your body burns energy and processes nutrients. It provides valuable insights into your metabolism, helping you understand how many calories your body burns at rest (Resting Metabolic Rate or RMR) and during physical activity.

It involves measuring your body’s oxygen consumption and carbon dioxide production, often through advanced techniques like indirect calorimetry.

By understanding your body’s energy expenditure and preferred fuel sources, you can tailor your diet and exercise routine to match your body’s specific needs, allowing you to optimize your nutrition, fitness, and weight management objectives.

An at-home metabolism test measures specific metabolic hormones that play a significant role in influencing your body’s metabolism. These hormones include:


Often referred to as the “stress hormone,” cortisol plays a crucial role in responding to stress and regulating various metabolic processes. Fluctuations in cortisol levels can impact how your body handles glucose, fat storage, and energy utilization. A metabolism test may be used to identify abnormal cortisol levels, which can indicate underlying health issues such as adrenal gland disorders or chronic stress.

Free Testosterone

Testosterone is a key hormone influencing metabolism, muscle mass, and fat distribution in males and fertility and bone health in females. Free testosterone refers to the unbound, biologically active form of this hormone in the bloodstream. Abnormalities in free testosterone levels can contribute to metabolic disturbances, affect energy levels, and influence body composition.

Thyroid-Stimulating Hormone (TSH)

TSH is produced by the pituitary gland and stimulates the thyroid to produce thyroid hormones that regulate metabolism. Elevated or reduced TSH levels may indicate thyroid dysfunction, affecting your body’s metabolism, energy levels, and overall well-being.

While these tests can help assess your endocrine system and overall health, they don’t directly measure your metabolic rate or explore how your body uses calories. But they can help you understand if your metabolism is properly supported with the right hormone levels, which may help guide potential weight loss or gain strategies.

There are several types of metabolic testing, each providing distinct insights into your body’s metabolic processes:

  • Resting Metabolic Rate (RMR) test. This test measures the number of calories your body burns at rest, helping tailor your daily calorie intake for weight management or performance goals.
  • Maximum volume of oxygen (VO2 max). This test evaluates your body’s response to physical exertion, determining your aerobic and anaerobic thresholds and your maximum oxygen consumption (VO2 max). It’s especially valuable for athletes and fitness enthusiasts seeking to optimize their training programs.
  • Lactate threshold test. Your muscles produce lactic acid when you’re physically active. This acid creates the “burn” when you workout and the eventual muscle fatigue. The lactate threshold is the point when there’s too much lactic acid in your muscles, showing how much work you can withstand before becoming fatigued. It’s a test usually reserved for professional athletes and involves using a treadmill or exercise bike and having blood drawn at different points as activity increases.

Other tests

There are also tests that don’t directly evaluate your metabolism like the other tests do. Instead, these tests provide information that can potentially indicate metabolic issues. These include:

  • Body composition analysis. While not strictly a metabolic test, this assessment provides insight into your body’s muscle mass, body fat percentage, and overall body composition. Understanding these factors is essential for tailoring nutrition and exercise plans to achieve your specific fitness goals.
  • Comprehensive metabolic panel (CMP). A blood test that provides info on the body’s fluid balance, levels of electrolytes like sodium and potassium, and kidney and liver function.
  • At-home metabolic testing. You can test hormones at home with kits like the EverlyWell Metabolism Test and EverlyWell Perimenopause Test. Buy the kit, take finger-prick blood and saliva samples, and return them to get your results. They’re a convenient and low-cost option.

When it comes to exploring your body’s metabolism and gaining insights into hormone levels, you’ve got two primary options: professional metabolic testing and at-home metabolism kits that require a finger prick blood test.

These options differ significantly in what they cover, the depth of analysis, and the setting where they occur.

Professional metabolic testing is typically carried out in a clinic or fitness center. It involves a series of physical tests that evaluate your body’s energy expenditure and fuel utilization using specialized equipment. The tests are administered by trained healthcare professionals or qualified experts and offer precise and personalized results. You may also have a comprehensive metabolic panel blood test to gain a 360-degree picture of your metabolic health.

In contrast, at-home metabolism kits are designed for convenience and don’t involve professional supervision. These kits allow you to collect a small finger prick blood sample and a saliva sample and then mail them to a laboratory for analysis.

The kits focus on measuring specific metabolic hormones through the collected blood sample. However, the accuracy and reliability of your results may vary due to factors like your ability to follow instructions, sample handling, and transportation.

While these kits are usually at an accessible price point and offer a convenient way to obtain hormone measurements, they may lack the in-depth analysis and interpretation provided by healthcare professionals. As a result, you may face challenges in fully understanding and interpreting your hormone levels and metabolic health without expert guidance.

When considering metabolic testing options, it’s essential to consider your specific goals, the level of accuracy required, and the guidance you prefer. At-home metabolism kits can provide some general insights into hormone levels, but they may not replace the comprehensive evaluations and expert interpretation provided by professional testing.


At-home metabolic tests measure hormones that can affect metabolism. But, these tests don’t directly measure how much energy your body uses, like the professional tests do.

The cost of a metabolic test can vary depending on the type of testing performed, the location of the facility, and the expertise of the healthcare provider or fitness expert conducting the assessment.

On average, the cost of a Resting Metabolic Rate (RMR) test can range from $100 to $300, while more comprehensive tests like Indirect Calorimetry may cost between $200 to $500 or more. Prices may also be influenced by additional factors, like hormone analysis or body composition assessments.

In some cases, metabolic testing may be covered by health insurance plans. However, coverage varies widely among different insurance providers and policies. Some insurance plans may cover metabolic testing when it’s deemed medically necessary because you have specific health conditions or weight management issues. Insurance coverage may also depend on the recommendations of healthcare providers and the specific codes used for billing the tests.

Before scheduling a metabolic test, check with your insurance provider to see if it’s covered and to understand any associated co-pays, deductibles, or out-of-pocket expenses.

Also, if you’re interested in at-home metabolism test kits, many accept health savings account (HSA) or flexible spending account (FSA) payments. But again, do your homework and check before parting with your money.

Metabolic testing is a valuable tool for gaining a deeper understanding of your body’s energy expenditure, fuel utilization, and hormone levels. It involves scientifically analyzing your metabolism to provide precise data on your resting metabolic rate (RMR) and how your body uses energy during exercise.

At-home metabolism testing is another option that provides insights into hormone levels and identifies potential imbalances that could affect your metabolism.

Armed with this knowledge, you’ll be well-equipped to make targeted lifestyle changes, maximize your energy efficiency, and pave the way for a healthier, fitter, and more balanced you.
