There are several online brands that stock at-home metabolism tests. Below are some factors that people can consider before purchasing:

  • Sample collection: Most test kits require both a blood and saliva sample. Those uncomfortable using needles may prefer a product that only requires saliva samples.
  • Cost: At-home tests can be expensive, especially if individuals buy them for one-time use. Regular users may prefer a company that offers regular subscriptions at a reduced cost.
  • Consultations: Some companies offer free consultations so that customers can discuss their results with doctors or nurses.
  • Results: Product pages list the number of days that the laboratory takes to publish results. Most of the time, people receive them within a few days, and they can access them via email or through an online portal.

A metabolism test measures the rate at which the body uses oxygen or burns calories. It can estimate how many calories a person burns when at rest or during activity, which can help them with their fitness and weight goals.

Metabolism refers to the body’s process of converting food into energy. The body uses this energy for everyday tasks, including keeping warm, movement, and other activities.

Learn more about metabolism.

An individual can receive metabolic testing at some healthcare facilities and fitness centers. In addition, several companies offer home tests to help people determine their metabolic rate.

It is important to note that no home test can diagnose a health condition, so people should interpret their results with the help of a doctor.

Some metabolism tests look at key hormone levels that can affect a person’s metabolism. These test results could indicate a hormone issue that could be affecting an individual’s weight and other aspects of health. For example, many hormone metabolism tests look at cortisol levels, TSH, and free testosterone.


A hormone metabolism test may indicate a person has too much or too little cortisol. This hormone plays a role in regulating metabolism, the immune system, and how the body responds to stress.

Having too much cortisol for an extended period can lead to low libido. People with uteruses may have irregular periods or periods that stop altogether, which doctors call amenorrhea.

Having too much cortisol can also lead to Cushing’s syndrome. This condition can cause many symptoms, including high blood pressure, mood swings, and rapid weight gain around the face, chest, and abdomen.

In contrast, having too little cortisol may also be a sign of Addison’s disease, which can be life threatening without treatment. Some symptoms may include dizziness, fatigue, and unintentional weight loss.

Thyroid stimulating hormone

A hormone metabolism test may indicate whether a person has too much or too little TSH. This hormone plays a role in maintaining metabolism, muscle control, brain development, and heart and digestion functions.

Having too much TSH may indicate an underactive thyroid, or hypothyroidism. Some symptoms of this condition include feeling cold, fatigue, and experiencing unintentional weight gain.

In contrast, having too little TSH may indicate an overactive thyroid, or hyperthyroidism. Some symptoms of this condition include unintentional weight loss, feeling hot, and anxiety symptoms.

Learn more about TSH levels.

Free testosterone

Testosterone is a hormone that is present in both females and males.

Learn more about testosterone.

In females with too much testosterone, it can indicate polycystic ovary syndrome. Some symptoms of this condition include acne, more body and facial hair, and a deeper voice.

Males with too little testosterone may experience increased body fat, sleep disturbances, and erectile dysfunction.

There are four types of metabolic tests. The most common home test that screens certain possible health conditions are metabolic hormone tests.

Home metabolic testing often looks at hormone levels in the blood or saliva. In addition to screening for hormone levels that may suggest an underlying condition, these tests may also indicate causes of weight gain.

The following hormones may play a role in weight gain and loss:

  • Cortisol: Research has shown that higher cortisol levels could predict more weight gain.
  • TSH: Researchers are not sure how much of a role the thyroid and the TSH have on weight loss. However, a 2017 study indicates that a higher presence of free thyroid hormones predicts more weight loss in adults with obesity.
  • Free testosterone: Research indicates that testosterone therapy may help males with low testosterone and obesity lose weight. The researchers suggest that testosterone therapy may encourage sustained weight loss and maintenance of a person’s weight goal compared with other treatments.

However, people should always interpret their metabolic test results with the help of a doctor. If a person receives a test result that indicates hormone levels that are too low or too high, they should contact a healthcare professional for further tests.

At-home metabolism tests are not substitutes for medical advice. People should always contact a doctor to discuss their results.

An individual can speak with a doctor if they receive a metabolism test result that shows their hormone levels are too low or too high. Although the test cannot diagnose what is causing these uncharacteristic levels, a doctor can.

A person interested in using the home metabolic test for weight loss or maintenance should speak with a doctor, nutritionist, or fitness professional, who can help design a diet and exercise program that meets their requirements.

How do you test your metabolism?

At-home metabolism tests check hormone levels that may influence a person’s metabolic rate. By checking these levels, tests can estimate whether a person’s metabolism is average for their age.

What does a metabolic test show?

A metabolic test estimates how fast a person burns calories while not exercising. Metabolism tests can estimate whether a person’s metabolic rate is average or outside typical ranges.

Can a metabolism test help you lose weight?

A metabolism test, in itself, cannot help people lose weight. It can give people a more in-depth view into how fast their body burns calories, which people can then use to tailor diet and exercise regimes.

What is a good metabolism score?

Metabolism is a reaction that provides the body with energy. Food and drink provide energy, which the body metabolizes to keep it healthy. The body uses this fuel for movement, growth, reproduction, and development.

The rate at which a person metabolizes food and drink depends on several factors, including:

  • age
  • sex
  • race
  • exercise
  • diet

Home metabolic tests can indicate whether a person’s hormone levels are too high or too low. Having hormone levels that are too high or low can lead to symptoms such as fatigue, mood swings, and unintentional weight loss or gain.

People should contact a doctor once they receive their test results to determine the cause of these uncharacteristic hormone levels.
