Blood Testing For Weight Loss


Blood testing for weight loss is an innovation in the field of weight loss and obesity management. It is a new method of measuring fat in human blood. A recent study shows it to be at least as effective as standard BMI calculation methodologies. This article will help you understand what blood tests for weight loss is, how it works and the health benefits of weight loss.

Your thyroid is a tiny gland located in the front of your neck that controls your metabolism and plays a substantial role in how much weight you lose. But many people have thyroid problems and don’t realize it. Fortunately, there are steps you can take to improve your metabolism, eat healthier, and lose weight. Here’s how to trick your thyroid to lose weight and give your body what it needs!

Blood Testing For Weight Loss

A blood test offers insight into biological processes and body functioning that can contribute to difficulty with weight management. Walk-in Labs offers a blood test for weight loss that assesses the functioning of many of the body’s mechanisms that control weight loss and weight gain.

Comprehensive Metabolic Panel (CMP-14)

The CMP-14 includes 14 different blood tests that all relate to the metabolic processes in the body. It includes a glucose test that can detect the presence of diabetes, a disease highly related to obesity. The panel also includes tests that measure both kidney and liver functioning. These vital organs filter out proteins and waste products that are produced during the metabolizing process. Fluids, electrolytes, and minerals in the blood are also measured. If the body is low on fluids or electrolytes the metabolic process slows down, leading to potential weight gain or trouble losing weight. You can order a Comprehensive Metabolic Panel (CMP) online without insurance or a doctor’s prescription.

Complete Blood Count (CBC)

A CBC blood test measures the balance and concentration of white and red blood cells and platelets in the blood. If the blood cells are not in balance the body cannot function optimally, which may cause weight gain. The CBC can also test for anemia, a condition caused by low levels of iron in the blood. This can lead to extreme fatigue and a decrease in amount of energy being burned by the body.

Lipid Profile

The lipid blood test is used to measure cholesterol types and levels. The levels of “good” versus “bad” cholesterols are important in determining risk of heart disease. Bad cholesterol can build in the arteries of the heart making it more likely for a blood clot to completely block off the artery causing a heart attack. Risk of heart disease can be decreased with diet and exercise. Lipid profile levels should change with weight loss.

Dehydroepiandrosterone (DHEA) Sulfate

DHEA Sulfate is present in both men and women and works as a male sex hormone. It is important in the development of male secondary sex characteristics. When DHEA is metabolized it can be transformed into testosterone, another male hormone, or estrogen, a female hormone. Hormones play an important part in maintaining weight; and if there is an excess of DHEA in the blood, there is most likely a problem with the metabolizing process.

Testosterone Total

A testosterone test can assess the level of masculinization in men and women. Obesity can negatively affect levels of testosterone in men. If women have too much testosterone in their blood, the hormone can affect their ability to lose weight.


Progesterone is a hormone that women produce during ovulation. The levels increase during this time to prepare the uterus for a fertilized egg. One can expect progesterone levels to be ten time higher in pregnant women than in non-pregnant women. However, high levels of progesterone in men or in women who are not pregnant can stall weight loss and also have more serious health implications, such as being at a higher risk for certain types of cancer.


An estradiol test is an important blood test for weight loss. Estradiol is a hormone produced in the ovary and helps in the development of female secondary sex characteristics. A lack of estradiol has been shown to increase food craving and overeating while reducing the body’s ability to burn fat.

C-Reactive Protein Cardiac

C-reactive is a type of protein found in the blood. The C-reactive protein cardiac blood test provides information on the overall level of inflammation in the body and is most often used to test for risk of heart disease. A high level of C-reactive protein in the blood is usually seen in conjunction with other heart disease risks, such as obesity and metabolic problems. Losing weight will usually lower C-reactive protein levels. Order a CRP Blood Test online.

Thyroid-Stimulating Hormone (TSH), Thyroxine (T4) Free Serum, Tri-Iodothyronine (T3) Free Serum

These three blood tests are for thyroid function assessment. The thyroid is a gland that that regulates the metabolic system. When people are having weight problems, one of the medical steps is to order a thyroid panel. Hyperthyroidism, where the gland produces too much of the thyroid hormone, can cause weight loss or an inability to gain weight. Hypothyroidism, where the thyroid gland is less active, can cause weight gain or an inability to lose weight.


This blood test is used to measure risk of heart attack and other heart related problems. Homocysteine, an amino acid, is metabolized by folic acid and vitamin B6 and B12. If the amino acid is not metabolized and stays in the blood, then the body is at a higher risk of heart problems. Eating a healthy and well balanced diet can help the body have the nutrients it needs for the metabolizing process

Blood Tests For Weight Loss

We bring to you these proven blood tests that will help you determine the root cause of your weight gain which will further aid you in fighting the cause in order to fight the weight,

1. Complete Liver Profile

The blood tests that come under the liver profile or liver function tests are ALT, AST, and GGT.

Why request these blood tests is because the liver is one of the major organs in the body which takes care of detoxification.

Detoxification is nothing but getting rid of the toxins, which also include excess fat, from the body. The liver helps in fat metabolism.

An overworked liver or a dysfunctional one can mean a buildup of toxins in the blood, inflammation as seen in obesity, and a fat accumulation around the belly.

All of us know how stubborn belly fat is to lose! So if you are looking at long-term weight loss, pay attention to your liver health.  That may hold a clue to your weighty issues!

2. Lipid Profile

The test which comes next in line is the lipid or the fat profile test. The blood test that comes under a lipid profile test is HDL cholesterol levels, LDL cholesterol levels, total cholesterol, and triglycerides.

As you may know, high levels of LDL and total cholesterol sound an alarm bell for your overall health; not just weight loss.

On the other hand,  a high or optimum level of HDL or good cholesterol is definitely a good sign. Get this report to a nutritionist for a diet-related solution.

3. Thyroid Hormone Test or a Thyroid Blood Test

A thyroid hormone blood test involves measuring T3, T4, and TSH levels. Do you know, the thyroid hormone works on every cell of the body controlling it. This also means our metabolism.

A thyroid-stimulating hormone high level can cause a reduction in your metabolic rate (the amount of energy always burnt for heart beating, thinking, breathing, etc).

Not good news if you’re looking for weight loss. Read more about how thyroid hormones affect your weight.

4. Diabetes or Insulin Profile Test

A fasting and postprandial blood glucose test, same for the insulin levels can be done. Insulin is known to be a fat-building hormone. So excess levels are sure to guarantee the accumulation of fat in the body.

Not only does insulin result in fat storage, but it also prevents the breakdown of fat as an energy source.

Diabetes is a condition signified by an increase in circulating insulin levels, leading to insulin resistance. Hence it is common sense to get your blood sugar and insulin levels tested.

5. Iron Tests

The blood tests that you can request at serum iron, hemoglobin, ferritin, transferrin, total iron-binding capacity.

This will help you understand your iron status. Now, weight loss is dependent on the availability of many nutrients, iron being one of them. If you are iron deficient, then you may experience fatigue and tiredness.

In this scenario, even your metabolism slows down. Exercise may also seem like a difficult task when deficient in iron.

Your dietician can help you out with ways to prevent iron deficiency by altering your diet. And studies have shown that correcting iron deficiency induces weight loss. 

6. Vitamin D and Vitamin B12 Tests

Vitamins and weight loss? Let us tell you the results of a study. Researchers have found that our body has a switch to control weight.

The minute it reaches a set mark, it tries to maintain our body weight at that mark.

The entire problem starts when this set mark increases which happens during winters. Winters are also when vitamin D, the sunshine vitamin, is not available.

So when you are deficient in this vitamin, your body thinks it is winter and starts piling on fat! [4] Similarly, B-complex vitamins are important for the digestion and utilization of carbohydrates in the diet.

In their absence, this process gets disrupted leading to fat deposition. Hence it is important to have a diet that is replete with these nutrients.

How to Trick Your Thyroid to Lose Weight

A: The T3, T4, and TSH levels are evaluated during a blood test for thyroid hormones. Do you know that the thyroid hormone affects and regulates every cell in the body?: Thyroid hormones stimulate multiple metabolic processes, mainly regulating basal metabolic rate, fat mobilisation-increasing concentrations of fatty acids in plasma, etc., carbohydrate metabolism-regulation of gluconeogenesis and glycolysis. Thyroid hormones have been used as a weight loss tool in the past. Many studies have shown that excess thyroid hormone treatment can help with the increase in the rate of weight loss than can be achieved by dieting alone. However, once the excessive thyroid hormone supply is stopped, the weight is usually regained and turns into a medical condition where the thyroid gland becomes underactive to produce thyroid hormones to keep the body running normally. Low thyroid hormone levels cause the body’s functions to slow down, leading to general symptoms like dry skin, fatigue, loss of energy, and memory problems. A high dose of the thyroid-stimulating hormone might lower your metabolic rate

Health Benefits of Weight Loss

1. Helps regulate blood sugar and diabetes

Losing weight improves insulin sensitivity in people with type 2 diabetes, says Preeti Pusalkar, a certified clinical nutritionist with Hudson Medical Center, a primary care provider in New York City. 

Excess body fat leads to an increase in adipose tissue, which causes inflammation and interferes with the function of insulin — the hormone that helps regulate blood sugar levels. 

Weight loss reduces adipose tissue, which allows the body to manage blood sugar more effectively. Plus, you don’t have to lose that much weight to see results. Research has found that just a 5% reduction in body weight improved blood sugar levels in adults. 

2. Improved heart health 

Losing weight can also improve heart health by reducing pressure on arteries, meaning the heart doesn’t have to work as hard to pump blood through the body. The result is lower blood pressure and low-density lipoprotein (LDL) cholesterol levels — the “bad” kind of cholesterol that can increase your risk of heart disease, Pusalkar says. 

And it doesn’t matter if you lose weight through diet and exercise or weight-loss surgery like metabolic surgery — you’ll reap benefits regardless, according to a large 2020 study.  

Researchers examined the effects of weight loss surgery on obese patients who either had weight loss surgery or who lost weight through lifestyle changes. The risk of heart disease for the surgical group decreased after a 5% to 10% loss of body weight while the nonsurgical group saw a decrease after losing about 20% of body weight. 

3. Decreased risk of stroke 

Excess weight can increase blood pressure, and therefore your risk of stroke. This is because high blood pressure puts a strain on your blood vessels, making them stiffer and more likely to cause blood to clot. 

“Losing weight helps improve the efficiency of the heart due to less constricted blood vessels,” Pusalkar says. 

4. Better sleep 

Overweight people are more likely to suffer from sleep apnea — a disorder characterized by disrupted breathing while sleeping. Excess weight can increase fat deposits in your neck, which can obstruct your airways. 

If you suffer from sleep apnea, losing weight likely won’t entirely cure the condition. However, losing just 10% to 15% of your body weight can improve sleep quality and reduce the severity of sleep apnea in moderately obese patients, according to the National Sleep Foundation. 

5. Improved mobility 

Losing weight alleviates pressure on knees and joints, which can improve mobility, Pusalkar says. A large 2012 study of obese adults with type 2 diabetes found as little as a 1% drop in weight cut mobility limitations, such as difficulty walking or climbing stairs, by more than 7%. 

6. Higher self-esteem 

While there is no direct correlation between weight loss and self-esteem, some studies show that weight loss can improve mood and self-confidence. 

A 2014 review examined 36 studies to determine the psychological benefits of weight loss. Researchers found consistent improvements in body image, self-worth, and general well-being among subjects who lost weight.
