Your Guide to Intolerance Testing for Greater Well-being

Do you often feel inexplicably tired, struggle with bloating or skin problems, even though you generally eat healthily? If so, an intolerance test could uncover the hidden causes. Often, it's not classic allergies, but rather delayed IgG reactions to foods that are behind such diffuse symptoms.

When the Body Suffers in Silence: Finding the Cause

You can imagine your body as a finely tuned orchestra. Every food you eat plays an instrument. But what happens when an instrument suddenly plays a wrong note? Sometimes this note is loud and shrill – an immediate bang. Much more often, however, it is quiet and barely audible, but still disturbs the harmony in the long run.

This is precisely why so many people suffer from symptoms without knowing the cause. They look for the loud bang, but overlook the quiet background noises that affect their well-being day after day.

Allergy or Intolerance? The Crucial Difference

The loud bang is the classic food allergy. Here, your immune system immediately and violently raises the alarm by releasing so-called IgE antibodies. Symptoms – from skin rashes and swelling to shortness of breath – usually appear within minutes. This reaction is clear and can be easily attributed to a specific trigger.

Much more common, however, are the quiet background noises: delayed food intolerances. Your body forms IgG antibodies in response to certain food components. The catch is: the symptoms only appear hours or even up to 72 hours later.

An IgG-mediated reaction is not an allergic emergency, but rather a sign that your immune system is overreacting to a food. This constant stress can lead to chronic, low-grade inflammation, which manifests itself in various symptoms.

This enormous time delay makes it almost impossible to identify the culprit without a targeted intolerance test. Who would have thought that Monday's dinner could be responsible for Wednesday's headache? You might be wondering how to distinguish between the different types of intolerances? In our article, you can learn more about the types of intolerances that exist.

Intolerance vs. Allergy at a Glance

This table summarizes the key differences so you can better categorize your symptoms.

Characteristic Food Intolerance (IgG-mediated) Food Allergy (IgE-mediated)
Type of Reaction Delayed immune response Immediate immune response
Timeline Hours up to 72 hours after consumption Within minutes to max. 2 hours
Symptoms Non-specific: Bloating, fatigue, headaches, skin problems Clear: Itching, swelling, rash, shortness of breath, circulatory problems
Antibodies Immunoglobulin G (IgG) Immunoglobulin E (IgE)
Severity Burdening and chronic, but rarely life-threatening Can be mild to life-threatening (anaphylactic shock)

As you can see, the differences are significant. While an allergy is immediately obvious, an intolerance often creeps into everyday life unnoticed.

A Widespread Problem Many Cannot Classify

If you recognize yourself in these descriptions, you are definitely not alone. Many people feel that something is wrong but cannot put their finger on it. Current data impressively confirm this feeling.

A representative YouGov study from 2021 shows that around 21% of adults in Germany are affected by allergies or intolerances to foods such as milk, gluten, or nuts. What is also interesting: women reported being affected significantly more often (62%) than men. If you would like to read the entire study, you can find more information about the study results on doc-ulm.de here.

A blood test that specifically measures IgG antibodies, such as the mybody®x Intolerance Test, can provide valuable clarity here. It analyzes your individual immune reaction to a variety of foods and helps you unmask the "silent troublemakers" in your diet. This finally gives you a concrete starting point to take your well-being into your own hands and restore harmony in your body.

What Test Procedures Exist and What They Really Say

The search for the right "intolerance test" can quickly feel like an impenetrable jungle. Everywhere you read about IgG tests, breath tests, or genetic tests. Don't worry, we'll shed some light on the matter and explain simply which procedure makes the most sense in which situation.

Imagine your immune system as your body's security team. A classic allergy test (IgE test) looks for the loud "alarm bells" - the IgE antibodies. They trigger an immediate, often violent reaction in the case of a real allergy. This is like an alarm system that screams when there's a break-in.

An IgG blood test, like the mybody®x Intolerance Test, works differently. It doesn't listen for the loud alarm, but rather detects the "silent observers": the IgG antibodies. An elevated level of these antibodies is a sign that your immune system is excessively dealing with a specific food. So it's not a sudden alarm, but rather an indication of chronic overload, which can lead to the typical, delayed symptoms.

The IgG Blood Test for Delayed Reactions

The IgG blood test is the right tool when you suffer from diffuse, chronic symptoms that appear hours or even days after eating.

  • What is measured? The concentration of IgG antibodies against a large selection of foods.
  • How does it work? A few drops of blood from your fingertip are enough. The laboratory then analyzes which foods your immune system reacts most strongly to.
  • When is it useful? For non-specific symptoms such as constant fatigue, bloating, skin problems, or headaches that you simply cannot attribute to a trigger.

An elevated IgG level is not an allergy diagnosis. Rather, see it as your personal guide. It shows you which foods are currently stressing your system and where a break might be useful to regain balance.

Breath Tests for Sugar Intolerances

A completely different matter are intolerances to certain types of sugar that your body cannot digest properly. This is where breath tests come into play.

  • What is measured? The concentration of hydrogen (H2) in your exhaled breath after you have drunk a test solution (for example, with lactose or fructose).
  • How does it work? If the sugar is not broken down in the small intestine, it moves on to the large intestine. There, bacteria feast on it and produce hydrogen, which you then exhale through your lungs.
  • When is it useful? If lactose intolerance (milk sugar) or fructose malabsorption (fruit sugar) is suspected. These typically manifest as acute gastrointestinal complaints shortly after consumption.

While breath tests therefore detect very specific digestive problems, an IgG test such as the mybody®x Intolerance Test gives you a much broader view of your immune system's reactions.

In fact, such complaints are more widespread than many assume. According to a Statista survey, only 82% of Germans state that they have no food intolerances. This means, conversely, that up to 18% of the population struggles with them. And although the Food Information Regulation (LMIV) now requires 14 main allergens to be clearly declared, tests remain a crucial key to unmasking hidden culprits. You can read the figures yourself in the survey on food intolerances on Statista.de.

How to Interpret Your mybody®x Report Correctly

Finally, it's here: Your personal results report from your intolerance test. Before you lies an insightful list of foods, each with its own value. But what do you do with all these numbers and graphics now? Don't worry, you're in the right place.

We'll translate the jargon for you and show you what the results really mean for your daily life. Let's decipher together what your body is trying to tell you and what first steps you can take from it.

What a High IgG Value Really Means

First things first: a high IgG value for a particular food is not an allergy verdict. It also doesn't mean that you have to ban this food from your diet forever. Rather, see it as valuable information from your immune system, signaling to you: "Hey, I'm pretty busy with this food right now!"

Imagine it like an overflowing email inbox. Most emails (foods) are processed quickly and unnoticed. But from some senders (certain foods), there's such a flood of messages that your inbox overflows and your whole system is stressed. A high IgG value is a sign of just such a "message flood" that keeps your immune system busy.

Understanding the Reaction Classes

In your mybody®x report, we have clearly categorized the results into different levels. This gives you a quick overview of where you can start.

  • No or weak reaction: For these foods, everything is in the green zone. Your body copes perfectly with them.
  • Moderate reaction: There's more going on here. It might be worth taking a closer look at your consumption of these foods and perhaps eating them a little less often.
  • Strong reaction: These foods are currently challenging your immune system the most. They are the top candidates for a conscious dietary change to give your body a well-deserved break.

This classification is your personal compass. It shows you where you can start to relieve your system and get symptoms like bloating, constant fatigue, or skin problems under control. If you want to delve deeper into the science behind IgG reactions, feel free to read our more detailed article on blood intolerance testing.

Your report is not a final judgment, but the starting point of an exciting journey of discovery to your own body. It gives you the tools to take action and specifically improve your well-being.

Context is Key

Sometimes, a high IgG value simply arises from eating a certain food very often. As a result, your immune system is constantly dealing with it and proactively produces more antibodies. This does not mean that this food is "bad" for you, but simply that a break or more variety on your plate would be a good idea.

That's why it's so important to always consider the results in conjunction with your personal eating habits. And that's exactly where we're going now. It's not about strict deprivation, but about smartly adjusting your diet.

Instead of banning foods forever, you'll next learn the principles of an elimination and rotation diet. This is the first, but crucial step to transforming the insights from your test into noticeable well-being.

Your Action Plan After the Test for Tangible Results

You have your test results in hand – a great first step! But knowing is only half the battle. The real change begins now, when you put your mybody®x report into action. See this guide as your personal roadmap to turn the results of your intolerance test into an effective plan for greater well-being.

Based on your individual mybody®x result, we will now show you how to specifically adapt your diet. Don't worry, it's not about giving up everything forever. Rather, you'll give your body a conscious break so it can regenerate and rebalance.

Phase 1: The Elimination Diet as a Reset for Your Body

The most important and effective step directly after the test is the so-called elimination diet. This sounds strict at first, but it isn't at all. Rather, imagine it as a kind of "reset button" for your gut and immune system.

The principle is very simple: For a manageable period of about four to six weeks, you specifically refrain from the foods for which your test showed a moderate to strong IgG reaction. By removing these potential troublemakers from your diet, you give your overwhelmed immune system a chance to finally calm down. Chronic inflammation can subside, and your gut can recover.

Many of our customers notice a real difference after just a few days: the tormenting bloating subsides, energy returns, and even the skin often visibly improves.

Important to understand: The elimination phase is not a lifelong sentence. It is a temporary, therapeutic measure. Your goal is to restore balance in your body and lay a healthy foundation for your future diet.

Get Creative in the Kitchen: Discover Alternatives

Giving up certain foods doesn't mean your meals will be boring now – quite the opposite! See it as your chance to try new things and expand your culinary horizons.

  • Reacting to cow's milk? There are fantastic plant-based drinks made from oats, almonds, or coconut. Cheese alternatives based on nuts or seeds are also an exciting discovery.
  • Reacting to wheat? Dive into the world of pseudocereals like quinoa, buckwheat, or amaranth. Pasta made from lentils or chickpeas is not only delicious but also rich in protein.
  • Reacting to chicken eggs? When baking, applesauce, ground flaxseed (as "flax egg"), or a ripe banana are great substitutes. A hearty "scrambled egg" can be wonderfully conjured up from chickpea flour or silken tofu.

You'll be amazed how many delicious and healthy options there are once you start looking. Your mybody®x report also gives you a list of all the foods you don't react to – use it as inspiration for your next shopping list!

One intolerance that many only notice in adulthood is to dairy products. A study by the Kaufmännische Krankenkasse (KKH) shows that the diagnosis of lactose intolerance has increased sharply in Germany in recent years. According to KKH, three times more women than men are affected, typically complaining of gastrointestinal problems because they lack the enzyme lactase. If you want to know more about the background, you can find further insights into the study on lactose intolerance on deutschlandfunk.de.

Phase 2: Targeted Reintroduction

After the four to six weeks of the elimination phase comes the most exciting part: provocation or reintroduction. Now you play detective and find out which foods actually trigger your symptoms and, above all, in what quantities you might still tolerate them.

The plan: Reintroduce the avoided foods individually and with an interval of two to three days. On the test day, eat a normal portion of the food and observe your body very closely over the next 48 to 72 hours.

It's best to keep a small symptom diary. Note how you feel. Do your old symptoms return? Then you've probably unmasked the culprit. If everything remains calm, you can move on to the next food. This way, you gradually create your very own, tolerable diet plan.

Professional Support for Sustainable Success

The path to greater well-being is a personal journey, but you don't have to walk it alone. The results of an intolerance test are an invaluable tool, but the correct interpretation and implementation determine long-term success.

This is precisely why your mybody®x test always includes free coaching with our experienced team of experts. Our coaches help you read your findings correctly, develop a feasible action plan with you, and provide practical tips for everyday life. A conversation with your doctor or a nutritionist is always a good next step to holistically shape your path to greater health and quality of life.

Frequently Asked Questions About Intolerance Testing

You've already read a lot about the intolerance test, the different methods, and the right steps after the result. Nevertheless, there are always uncertainties and questions surrounding IgG tests. In this last section, we will clear up the most common doubts.

We want to give you a clear and honest picture so you can make a confident decision for your health.

Why is the validity of IgG tests debated?

Perhaps you have heard that IgG tests are controversial in science. That's true - and the reason is actually quite simple: an elevated IgG level alone is not proof of an intolerance. It primarily indicates that your immune system has been in contact with a food and has formed antibodies. This is a completely normal process.

Don't view the IgG test as a sole diagnosis, but as an important puzzle piece in your investigation. It's a strong indicator of which foods are currently keeping your immune system particularly busy.

And that's precisely where its invaluable worth lies: The test gives you a personal "wanted list" of the main suspects. If you then combine this list with an elimination and provocation diet, as described in the previous chapter, it becomes an incredibly powerful tool. It allows you to specifically find out whether you feel better when you avoid these foods. For thousands of people, precisely this practical approach has been the decisive breakthrough.

Do I have to avoid positively tested foods forever?

No, absolutely not! That's one of the biggest myths surrounding the intolerance test. The goal is never lifelong, strict abstinence. It's much more about giving your body a strategic break for a manageable period of time.

Imagine it like a traffic jam in your gut. The elimination diet acts like a temporary road closure so that the jam can clear. Once the road is clear again, traffic (i.e., the reintroduction of foods) is slowly and controllably allowed back in.

  • Temporary avoidance: You avoid foods with a strong reaction for about 4-6 weeks. This gives your immune system time to calm down.
  • Targeted reintroduction: Afterwards, you reintroduce each food individually and thus test your very personal tolerance limit.
  • Rotation principle: In the long term, a rotation helps you, in which you only eat certain foods every few days. This prevents your immune system from being overloaded again.

You'll see: Often you can enjoy many of the foods again in moderation later without the old complaints returning. It's about a clever balance, not permanent abstinence.

Why doesn't health insurance cover the test?

IgG tests like the mybody®x test are generally a self-pay service, often referred to as an IGeL service (Individual Health Service). The reason is that their predictive power – as explained above – is not yet sufficiently proven from a scientific perspective to be included in the statutory health insurance catalog of services. Health insurance companies usually focus on diagnosing acute, IgE-mediated allergies.

However, the decision to invest in one's own health is often one of the best one can make. Many people suffer for years from diffuse complaints, while conventional examinations find no cause.

The cost of an IgG test is an investment in your quality of life. It can save you years of guesswork and show you a direct path to greater well-being, because you take control of your diet yourself.

For many of our customers, the clarity gained and the noticeable improvement in their symptoms make this investment more than worthwhile.

Does the home test replace medical consultation?

No, and this is a very important point. A self-test like the mybody®x Intolerance Test is not a substitute for a medical diagnosis or treatment. Especially in cases of severe or prolonged complaints, you should always consult a doctor first to rule out serious illnesses.

See the test as a first, simple, and discreet step on your journey. It is the perfect complement to medical advice, as it provides you with concrete, personal data that you can discuss with your doctor or therapist.

  • You gain clarity: The test gives you initial clues and a clear direction in which you can investigate further.
  • You become an equal partner: With your report, you can ask more targeted questions and develop a plan together with your doctor.
  • You take responsibility: You no longer wait passively, but become active yourself. You start your own journey of discovery and learn to better understand your body's signals.

The mybody®x test gives you back the power. You go from being affected to being the creator of your own health and receive the tools to make targeted changes and sustainably bring more well-being into your life.


Are you ready to stop guessing and take the first step towards greater clarity and well-being? At mybody®x, you'll find the right test to take your health into your own hands – scientifically sound and with personal support.

Discover your mybody®x blood test now and start your journey to a better body feeling.
