Many people today are interested in finding ways to manage their weight, with a significant portion of the American population struggling with obesity. This has led to an increased awareness that weight management involves more than just balancing calories consumed and expended. Weight Management Lab Tests are emerging as a valuable tool in understanding the complexities of weight loss.
Understanding Obesity and Weight Management
The Centers for Disease Control and Prevention (CDC) defines obesity using the Adult Body Mass Index (BMI). A BMI between 25.0 and 30.0 indicates overweight, while a BMI exceeding 30.0 signifies obesity. However, relying solely on BMI may not provide a complete picture of one's health. A high waist circumference, for example, can also be a cause for concern.
Many factors can contribute to weight gain, including:
- Excess calorie consumption: Particularly from foods high in sugar, fat, or both.
- Stress: Elevated cortisol levels due to stress can cause the body to retain fat.
- Lack of sleep: Insufficient sleep can disrupt hormone balance and contribute to weight gain.
- Age: As people age, they may start to gain weight due to various factors.
- Lifestyle: An unhealthy lifestyle can significantly impact weight.
- Genetics: Genes can also play a role in weight management.
It's important to note that there aren't any specific symptoms directly linked to obesity.
The Role of Blood Tests in Weight Loss
Weight Loss Lab Tests can provide insights into how your body functions and what it needs to perform optimally. These tests, along with your doctor's advice, can facilitate the creation of a personalized weight loss plan that suits your specific needs. For example, a CMP (comprehensive metabolic test) examines your metabolism and the functioning of your kidneys and liver. It can also detect abnormalities in your blood sugar levels.

A set of comprehensive baseline-biomarker tests is usually the initial step. These tests involve more than just looking better and losing weight.
Common Blood Tests for Weight Loss
Several blood tests can be helpful in assessing factors that affect weight management:
- Comprehensive Metabolic Panel (CMP): This test assesses your metabolism and the functioning of your kidneys and liver. It can also detect abnormalities in blood sugar levels.
- Hormone Levels: Hormones related to stress, thyroid function, and sex can significantly impact weight management. Lower than normal or elevated levels might indicate underlying conditions. Doctors might recommend lifestyle changes or treatments to help balance these hormones.
- Thyroid Hormones: These hormones control your metabolism, or the number of calories your body needs to function.
- Sex Hormones: Sex hormone production naturally declines with age, including the female sex hormones estrogen and progesterone and the male sex hormone testosterone.
- Cortisol: Stress increases cortisol levels, and this can cause your body to retain fat.
- Insulin Resistance Test: Early tests can diagnose the start of insulin resistance. When caught early enough, lifestyle changes can keep this condition under control.
Understanding Your Blood Test Results
Once your CMP results are available, your healthcare provider will share them with you, or they might appear in your electronic health record. The results may appear as a list or a table. In general, comprehensive metabolic panel results usually provide:
- The name of the blood test or what was measured in your blood (like BUN, calcium or ALT).
- The number or measurement of your blood test result.
- The unit of measure for that test, for instance, mg/dL (milligrams per deciliter). This indicates the amount of the substance in a certain volume of blood.
- The normal range for that test. These can differ slightly by lab, so be sure to only compare your number to the one given on your results for that specific test.
- A flag or note if your result is higher or lower than the expected range. Sometimes, your result will appear in red if it’s out of the expected range. It may also note if it’s in the normal range.
In most cases, you should have your CMP test results within one to two business days, though it could take longer.
Interpreting Abnormal Results
If any of the CMP results are outside the normal range provided by the lab, it could indicate:

- Liver disease
- Kidney disease
- Diabetes. Elevated fasting blood glucose is often a sign of Type 2 diabetes. Very high glucose levels, whether fasting or not, usually indicate Type 1 diabetes.
- High blood pressure (hypertension)
Keep in mind that an abnormal result doesn't necessarily mean you have a medical condition. Other factors, such as diet, certain medications, and health conditions, can affect your test results. If you have an abnormal result, your healthcare provider might order additional tests to confirm or rule out a specific diagnosis.
Hormonal Balance and Weight Loss
Since hunger, cravings, stress, and energy are all sensations that are managed by our hormones - balancing them should be the first step in everyone's weight loss regimen. Life Extension® offers a blood test to help get the hormonal balance part of your weight loss equation right.
Hormones are chemical messengers that tell your body what to do. They affect your mood, hunger, and metabolism.
Considerations for Hormone Testing
- Timing: Hormones are best drawn between 8-10 AM.
- Fasting: The test may be done fasting or 2-6 hours after eating. Both ways provide valuable information, though 2-6 hours after a meal provides a more realistic assessment of the state of your blood in everyday life.
- Hydration: Stay hydrated before the test.
- Medications: Take your medications as prescribed. If you are supplementing with any hormones, we suggest taking them approximately 2 hours prior to having your blood drawn to see peak levels.
- Hormonal Contraceptives: Hormonal contraceptives can interfere with progesterone and estrogen results.
- Menstrual Cycle: Pre-menopausal women: For a 28 day cycle, blood should be drawn on day 21 (day 1 is the day that bleeding begins).
Obtaining Weight Management Lab Tests
A weight management lab test is ordered online and involves having the test drawn at one of authorized patient service centers. Ulta Lab Tests provides highly reliable and accurate tests. These tests can help you make more informed decisions when it comes to your health.
Personalized Weight Loss Plans
Many people are also becoming more aware that managing their weight involves more than just calories out and calories in. That’s the difference between a commercial weight-loss program and a medical weight-loss program . A medical weight-loss program conduct a thorough physical exam, do bloodwork, and take a complete diet and weight history.

Once all the factors that affect your weight are fully understood, a personalized plan that can best help you can be created. HRT is only prescribed if hormone levels are low and affect energy, weight, and quality of life.
