Food Sensitivities Testing

Food Allergies and Intolerances Can Block Your Weight Loss Efforts

It’s no mystery that certain foods affect our bodies differently. However, pinpointing which foods we eat are to blame for disrupting our weight loss goals can be hard. Biohackers should stay informed about the foods known to trigger sensitivities.

Four by six square of circular colored icons of healthy foods.

Millions of People Are Undiagnosed

If you’re having difficulties maintaining a healthy weight, certain foods in your diet may be playing a role. An estimated 20 million adults in America have a food allergy,1 and even more have food intolerances that haven’t yet been diagnosed. Understanding how certain foods impact your body can make it easier for you to maintain overall optimum health.

Food Allergies Can Impact Body Biohacking Plans

Food allergies affect your immune system, while food intolerances impact your digestive system.2 Allergies can cause hives or other severe — and sometimes life-threatening — responses almost immediately after eating. Intolerances usually produce milder effects, such as an upset stomach, sometimes hours after eating.

Both allergies and intolerances can lead to chronic inflammatory diseases and are connected to inflammation and obesity.3 A study on children4 found that obesity and food allergies were significantly linked, but only in girls and not boys.

The most common foods people are sensitive to are yeast, eggs, cranberry, cow’s milk, chicken, lentils, and parsley.5 You can test whether your body is sensitive to these or other foods with a blood test6 that measures the total immunoglobulin G antibody present for each food category. Skin pricks are also sometimes used before full blood work is ordered.7

Start With a Food Journal Before Your Tests

Doctors will normally recommend that patients keep a food diary during this discovery phase, accompanied by an elimination diet to confirm findings. Narrowing down what is causing your body troubles can be a long process, but understanding your body’s sensitivities to certain foods will help you stay healthy for the rest of your life.

“An elimination diet process is to discover which foods make you feel like a rockstar and which foods are holding you back.”

Vitamins & Minerals Testing

Vital Vitamins and Minerals Are Necessary When Biohacking for Fat Loss, Enhanced Energy, and Well-being

Are you getting enough vitamins and minerals in your current diet? If not, a test could help you determine the underlying causes of your fatigue, weight struggles, or poor macronutrient absorption. Talk to your physician.

Illustration of a skeleton and organ systems with color-coded dots indicating which vitamins and minerals benefit what.

Fast 12 Hours Before You Test

Despite the public health cries for balanced diets, modern plates are rarely filled with enough fresh fruits and vegetables to supply the body with adequate daily levels of vitamins and minerals. An estimated 2 billion people throughout the world suffer from micronutrient deficiencies,1 which are known to impact weight and health in general.

Getting tested for deficiencies can help you address problems underlying lack of energy, fat accumulation, and the non-absorption of vitamins in food. It’s a two-part process: First, you’ll need to schedule a blood test to see what, if anything, you’re deficient in. Next, you’ll need to uncover the cause, which could simply be that you’re not eating enough of a specific kind of food. The underlying cause could also be an undiagnosed disease.

While it’s recommended to get this type of bloodwork done every few years, most people don’t make it a priority. Look for common symptoms of deficiency, like brittle hair or mouth ulcers.2

Doctors will tell you to fast for at least 12 hours before undergoing testing and to avoid all supplements and products containing biotin, which can lead to inaccurate results. Be open and honest with your physician and make sure all vitamin and mineral deficiencies are addressed, as these are directly linked to struggles with maintaining a healthy weight.


If you’re feeling fatigued, have shortness of breath, or experience unintentional weight loss, you may not be eating enough foods rich in B-12 and folate. Alternatively, your body may have trouble absorbing these vitamins. If your doctor discovers this through blood work, you’ll be diagnosed with vitamin deficiency anemia.3 Sublingual B-12 supplements can help. It comes in tablet and liquid form.

Vitamin D

Low levels of vitamin D have been associated with excess fat,4 and blood work can show if you need to increase your levels. If this is the case, your doctor may prescribe a supplement or encourage you to spend more time in the sun. A 10- to 30-minute walk in the midday sun every other day should be enough for you to maintain healthy levels if you have light skin. People with darker skin may require longer periods of exposure.5


Another cause of fatigue is iron deficiency anemia, which can be verified through blood work. Specific tests check your complete blood count, hemoglobin levels, blood iron levels, and ferritin levels.6 You may require an iron supplement if your levels are low. However, some people have low iron levels because they drink too much caffeine. Studies show that coffee and teas inhibit iron absorption by up to 39%.7 If coffee is the underlying cause, it’s always better to remove something from your diet than add extra supplements.

“There are 37 billion chemical reactions happening within your body every second. And every single one of these reactions requires vitamins and minerals to make it work.”

Organ Function Testing

Organ Health Testing: How to Supercharge Your Weight Loss Biohacking Efforts

If an organ is compromised, biohacking weight management will be difficult — or maybe even impossible. Test important organs to ensure your body can metabolize fat and balance hormones.

Illustration of an organ system with pop-outs showing the individual organs along either side.

Check Liver, Kidneys, and Thyroid Regularly

Certain organs are specifically tasked with functions associated with maintaining a healthy weight. Before you take steps toward biohacking your weight, a smart biohack is making sure your organs are functioning properly.

The organs associated with weight maintenance are primarily within the digestive and endocrine systems. Adipose tissue, or body fat, is actually considered an interactive organ within the endocrine system.1 If you address the underlying conditions of stressed organs, you can more easily maintain healthy homeostasis. When that’s achieved, you can more easily maintain a healthy weight.


Among other responsibilities in the body, the liver is responsible for metabolizing fat2 by making sure the body has enough energy in both fed and fasted states. When you have a fatty liver, which is often a result of obesity, diabetes, or high triglycerides,3 you can develop metabolic syndrome and symptoms of hormonal imbalance.4 Testing your liver function by measuring certain enzymes and proteins in your blood can alert you before serious disease develops.5 If tests confirm abnormal function, you can generally reverse the condition with weight loss and exercise.6


Kidney function is directly related to weight gain,7 as damaged kidneys cannot properly balance the salt and fluid levels within the body. Although an electrolyte imbalance can be associated with weight gain, people with chronic kidney disease tend to have the opposite experience.8 Testing your kidney function may involve a blood test and/or a 24-hour urine sample.9


A compromised thyroid is a common cause of unmanageable weight. An underactive thyroid, or hypothyroidism, is associated with weight gain10 while an overactive thyroid is connected to unintended weight loss. Even minor thyroid dysfunction can result in an extra five kilograms in body weight.11 The thyroid regulates metabolism, so measuring your TSH levels12 can determine its functioning. When preparing for your blood work, avoid estrogens from birth control pills and biotin supplements for accurate tests.

Hormone Testing

Biohacking Weight Is Impossible Without Balanced Hormones

Weight biohacking starts with understanding the vital role hormones play in regulating appetite, metabolism, and body fat distribution. Tests can shine a light on how your body can achieve hormonal balance and optimal weight.

A well-balanced rock stack with several smooth gray stones.

Urine Tests for Thyroid Stimulating, Cortisol, and Sex Hormones

Within the body’s endocrine system are special glands responsible for creating and releasing hormones into the bloodstream. Many of these hormones are directly responsible for our appetite levels, metabolism, and body fat distribution. When your hormones are balanced,1 you have a solid internal foundation for biohacking lifestyle changes. Sex hormones, thyroid-stimulating hormones, and cortisol levels are worth testing.

Thyroid Stimulating Hormone

There is a direct connection between obesity and too little thyroid hormone, just as there is a direct connection between being underweight and producing too much thyroid hormone.4 Thyroid disease impacts your insulin levels, which regulate blood sugar. When imbalanced, you can develop insulin resistance, which leads to diabetes.5 Testing the levels of thyroid stimulating hormone (TSH) in your blood will inform you of how well your thyroid is working.6


Produced in your adrenal glands, the cortisol hormone is your body’s way of regulating stress. Cortisol sends important signals within your body to regulate metabolism, blood sugar, inflammation, and fat storage.7 Multiple studies have linked cortisol with excessive abdominal fat.8 Checking your cortisol levels through blood, urine, or saliva tests9 is a first step toward stress reduction, along with developing habits such as mindfulness10 and other coping strategies.11

Sex Hormones

Both men and women need healthy levels of testosterone, estrogen, progesterone, and DHEAS for a variety of reasons, including maintaining an appropriate body mass index. Hormonal fluctuations in women resulting from menopause have been shown to increase the risk of obesity.2 Obese men, meanwhile, increase their testosterone levels when they lose weight.3 These hormones can be tested through blood testing, although sometimes doctors will order a 24-hour urine sample as well.

“Understanding your own hormonal dance and its effects is vital to taking charge of your health and well-being.”

Diabetes Testing

Undiagnosed Diabetes Makes Weight Loss Nearly Impossible for Biohackers

More than 37 million American adults have diabetes. The good news is that symptoms can often be prevented and even reversed with the right lifestyle interventions. To biohack weight loss and improve your overall health make sure you catch it early with simple tests.

Prediabetes Tests Encouraged for Everyone

When a person is diagnosed with diabetes, their body is either not producing adequate insulin (type 1), or it is no longer able to use it effectively to regulate the glucose levels in the bloodstream (type 2). Of the more than 37 million American adults with the disease, approximately 95% have type 2 diabetes.1 With this type of diabetes, patients develop insulin resistance as the pancreas produces more insulin in an effort to get cells to respond. Testing for diabetes early on increases your chances of being able to reverse your symptoms.2

Weight Loss Is Even More Important for Diabetics

Diabetes is directly linked to weight gain,3 as the excess blood sugar is stored as fat. Not only are people with diabetes more likely to be overweight, but they also have an increased risk of high blood pressure, unhealthy cholesterol levels, and strokes. Losing weight is more challenging with the onset of the disease, but the effort is worth it: When you lose even just 10 pounds, you dramatically reduce your risk for more serious symptoms.4 Plus, maintaining weight loss enhances insulin sensitivity, helping you reverse the disease.5

Talk to Your Doctor to Schedule a Test

Whether or not you have symptoms of prediabetes6, consider getting tested. There are a few ways to move forward with blood testing. You can order an A1C test, which measures your average blood sugar over the past few months. You can also fast overnight for a fasting blood sugar test, or you can complete a glucose tolerance test.7 Results usually come back quickly, allowing you to develop a biohacking strategy that can include lifestyle changes such as intermittent fasting and increased exercise.

“Type 2 Diabetes is not always a chronic and progressive disease. We need to stop treating it as such.”

Lipid Panel

Testing Heart Health Offers Biohacking Metrics for Weight Loss Success

Schedule a lipid test at the start of your weight loss journey to identify how diet and exercise routines impact your cholesterol and triglycerides. Keep checking before, during, and even after you’ve achieved your initial goals.

Lifestyle Changes Proven Effective if Elevated

In many ways, biohacking involves using science to improve your overall health. To accomplish this, you must create a plan (hypothesis) and measure it in a controlled way to allow you to determine if your plan is successful. A powerful way to monitor your fitness level as you focus on weight management is by completing a lipid panel in the earliest possible stages of your journey.

A Healthy Heart Is Necessary for All Biohacks

A lipid panel is a test that screens for cardiovascular health by measuring your cholesterol levels and triglycerides.1 Cholesterol is a waxy substance in the body used to build cells as well as make vitamins and hormones. The liver produces enough cholesterol for the entire body in itself, but we also introduce supplemental cholesterol through certain foods. Too much meat, dairy, and tropical oils can result in abnormally high levels of cholesterol, disrupting your system by clogging arteries.2 Triglycerides are energy stored in fat cells for future use. If you eat more calories than you burn, you may have elevated levels, which can contribute to arteriosclerosis and heart disease.3

Lipid Tests Usually Require Fasting Beforehand

If you’re over 45 for men or 50 for women, it’s a good idea to get a lipid test. This is especially important if you smoke cigarettes, are obese, don’t get enough exercise, have high blood pressure, or have a close family member with diabetes.1 To prepare for this blood test, you’ll likely have to fast for nine to 12 hours beforehand.4 If your lipid levels are elevated, lifestyle biohacks such as integrating a whole foods diet and regular exercise can help reverse the condition.5 Follow-up tests can help you keep track of your progress and celebrate victories that can’t be measured by a scale.6

“Be sure to ask your doctor to do a particle size test. This will check both your particle size and particle number.”

    Hemoglobin A1c (HbA1c) and fasting blood glucose tests are commonly used to assess blood sugar control and diagnose diabetes. Continuous glucose monitoring (CGM) provides real-time data on blood sugar fluctuations, helping individuals understand how different foods and activities impact their glucose levels.

  • What is the significance of lipid panel tests in biohacking?

    Lipid panel tests evaluate cholesterol levels, including LDL, HDL, and triglycerides. By monitoring lipid profiles, you can assess cardiovascular health and make targeted interventions, such as dietary adjustments, exercise, and supplementation, to optimize lipid balance and reduce the risk of heart disease.

  • Can lab tests reveal nutrient deficiencies that impact biohacking goals?

    Absolutely. Nutrient deficiency tests, such as vitamin B12, vitamin D, or magnesium, can uncover imbalances that may contribute to fatigue, poor cognitive function, or compromised performance. Addressing these deficiencies through supplementation or dietary changes can enhance overall biohacking outcomes.

  • Can biohacking lab tests be done without a healthcare provider?

    While certain lab tests can be done independently, it is advisable to consult with a functional medicine doctor or healthcare provider who specializes in biohacking. They can help interpret the results, provide personalized recommendations, and guide you in developing an effective biohacking plan based on your unique needs.

  • Which specific foods should I get tested for sensitivity to?

    When it comes to determining which specific foods to get tested for sensitivity, it depends on your individual health concerns and symptoms. However, there are some common food groups that are often included in food sensitivity testing. These typically encompass dairy products, gluten-containing grains (such as wheat, barley, and rye), eggs, soy, shellfish, tree nuts, peanuts, and certain fruits and vegetables.

    It’s important to consider your personal dietary habits and potential triggers for sensitivity. If you suspect a specific food or group of foods is causing adverse reactions, you may want to include those in your testing panel. Additionally, discussing your concerns and symptoms with a functional medicine doctor or healthcare professional who specializes in food sensitivities can provide further guidance on which foods to prioritize in your testing.
