Gene sequencing for your health, simply explained

Imagine having a kind of user manual for your body that shows you exactly how to improve your health in a targeted way. That is precisely what modern gene sequencing makes possible. It is the key to finally understanding why some diets simply don't work for you or which nutrients are especially important for you personally.

What gene sequencing can mean for you

Have you ever wondered why your body reacts completely differently to certain foods or training methods than other people's? The answer lies deep within your DNA. Gene sequencing is essentially the process of reading and analyzing your genetic code—the exact sequence of your DNA building blocks.

You can think of your DNA as a huge cookbook containing all the recipes for your body. Gene sequencing reads these recipes in precise detail and identifies the tiny, individual variations that make you unique. These variations can, for example, influence:

• Your metabolism: How efficiently your body processes fats, carbohydrates, and proteins.
• Your nutrient requirements: Whether you have a predisposition to deficiencies in certain vitamins or minerals.
• Your physical characteristics: How your muscles respond to training or how quickly you recover after exercise.

What once sounded like pure science fiction and was extremely expensive has become accessible to many thanks to rapid technological advances.

The cost of decoding a complete human genome has fallen dramatically: from around 100 million US dollars in 1990 to under 1,000 US dollars since 2015. This development makes gene sequencing accessible to all of us today.

This impressive progress allows companies like mybody-x to offer targeted, affordable DNA analyses. Instead of taking 13 years, as it did for the very first human genome, analysis now takes just a few days. This enables you to make informed decisions about your health based on your unique genetic makeup. You can read more about the development of genome sequencing in this statistic.

Stop guessing when it comes to nutrition

A simple saliva test, such as the mybody® DNA metabolism test, can finally give you the clarity you have been looking for. Instead of generic diet rules, you receive personalized recommendations that truly suit your body. Gene sequencing thus becomes your personal tool, helping you achieve your goals—whether losing weight, having more energy, or aging healthily—in a well-founded and effective way.

The goal is not to search for incurable diseases. Rather, it is about optimizing your own lifestyle. Your genes are not an unchangeable fate but a valuable source of information. When you understand how your body is “programmed,” you can adjust your diet and habits so that you can fulfill your full potential. You can also learn more about what your genes reveal about you in our article on the basics of genetics: find out more here.

How your genetic code is decoded

You have decided to take a look at your personal “user manual.” But how exactly does a simple saliva sample become a detailed analysis that gives you valuable insights into your health? The process of gene sequencing is highly scientific, but the individual steps behind it are clear and easy to understand.

Imagine your entire genetic material, your genome, as a huge library. This library is packed with books that together provide the complete blueprint for your body. For your personal analysis, however, we do not need to read every single book from beginning to end. Instead, we focus on specific chapters and sentences—precisely those that tell us how your metabolism works or how you process certain nutrients.

From the test kit straight to the laboratory

It all begins simply at home. With the mybody-x test kit, you collect a small saliva sample. It is easy and completely painless. This sample is the key because it contains your cells and therefore your unique DNA. As soon as your sample arrives at our laboratory, the actual analysis begins.

The first step is DNA isolation. Here, your pure genetic material is carefully separated from all other components in your saliva, such as proteins and bacteria. In the end, only your pure DNA remains—the valuable source of information for the subsequent gene sequencing.

Modern technology reads your genes

To read the crucial “sentences” in your genetic code, we use a highly advanced method: Next-Generation Sequencing (NGS). You can think of it like this: Your DNA is first broken down into countless small sections. These fragments are then multiplied millions of times and read in parallel, meaning simultaneously.

A powerful computer then reassembles these short sections like a puzzle and compares the result with a human reference genome. It is precisely during this comparison that the tiny but crucial differences become apparent—your individual genetic variants. And it is exactly these variants that determine whether, for example, you metabolize carbohydrates better than fats or have a predisposition to an increased nutrient requirement.

The entire journey from your saliva sample to your completed health plan can be summarized in three simple steps.

This graphic perfectly illustrates how a simple sample is transformed into a concrete, personalized plan for you through scientific analysis.

Quality and safety come first

The reliability of your results is our top priority. That is why we work exclusively with ISO-certified specialist laboratories. Every single step in the process is subject to the strictest quality controls, ensuring that the data obtained is completely accurate and reliable.

As soon as your sample arrives at the laboratory, it is pseudonymized. This means that it is immediately separated from your name and personal data and assigned a unique barcode. This guarantees the highest level of anonymity and maximum data protection throughout the entire analysis.

Once gene sequencing is complete, our bioinformaticians analyze the raw data. They are the ones who translate the complex genetic information into clear and, above all, actionable recommendations, which you will then find in your results report. Only at the very end is your result linked back to your customer account, so that only you can access it securely.

DNA itself is a fascinating molecule, and its structure is the foundation for all of this. If you want to delve even deeper into the subject, you can find more exciting details in our article about the structure of DNA.

As soon as your analysis is complete, your original saliva sample will be securely destroyed in accordance with regulations. Your genetic data belongs solely to you. It will never be used for anything else without your explicit consent. This careful and transparent process ensures that you can take advantage of gene sequencing with complete confidence and take control of your health.

What insights your genes really provide

The whole theory behind gene sequencing sounds fascinating, but what does it actually mean for you and your everyday life? Enough with the abstract theory—it’s time to get practical. Imagine no longer having to guess which diet or workout will work for you, but instead being able to make decisions based on your own personal blueprint.

This is exactly where DNA analyses for lifestyle questions come in. They are not about medical diagnoses, but about valuable insights into how your body works. This is the key to finally understanding why, despite all your efforts, you may not yet have reached your ideal weight or why you often feel more exhausted than others after exercising.

Finally understand how your metabolism works

One of the most fascinating insights your genes can provide concerns your metabolism. Many of us have already tried numerous diets—low-carb, low-fat, intermittent fasting—often with limited success. The reason is actually quite simple: there is no single diet that works for everyone.

A DNA analysis can determine what type of metabolism you have. It examines how your body naturally processes the three major nutrient groups:

• Carbohydrates: Do you use them as a turbocharged source of energy, or does your body tend to quickly convert them into fat stores?
• Fats: Are you a “fat type” who uses healthy fats particularly efficiently for energy production?
• Proteins: How high is your personal protein requirement to optimally nourish and maintain your muscles?

The mybody® DNA metabolism test analyzes these exact genetic markers. The result is not another diet rule, but a personalized recommendation for which nutrient distribution works best for you.

Imagine finding out that you’re a carbohydrate type. Instead of banning carbs altogether, you could learn to eat the right complex carbohydrates at the right time. The result: more energy and fewer cravings. This knowledge can change everything.

Optimize your training and recovery

Even in sports, a look at your genes can make all the difference. Your genetic profile reveals what type of athlete you are and how you can specifically take your performance and recovery to the next level.

• Muscle fiber type: Are you better suited to endurance sports (slow-twitch fibers), or are you a born sprinter or strength athlete (fast-twitch fibers)?
• Recovery capacity: Is your body naturally prone to stronger inflammatory responses after exercise?
• Risk of injury: Are there genetic indications of weaker tendons or ligaments that make adapted training advisable?

With this information, you can tailor your training plan perfectly to your needs. Instead of struggling through a standard program, you train more efficiently, prevent injuries, and give your body exactly the rest it truly needs.

From knowledge to concrete action

The true strength of gene sequencing lies in turning knowledge into an actionable plan. What good is it to know that you are predisposed to a particular vitamin deficiency if you do not know what to do about it?

This is exactly where mybody-x comes in. We provide you with more than just raw data—we translate it into clear instructions:

• Personalized nutrition plans: You will receive specific suggestions for meals and foods that suit your metabolic type.
• Personalized nutrient recommendations: You will learn which vitamins and minerals you should pay particular attention to and how best to absorb them.
• Tailored lifestyle tips: From the right training strategy to tips for better sleep—all tailored to your genetic profile.

Gene sequencing is no longer a thing of the future in Germany. It has been part of routine clinical practice since 2010, and thanks to projects such as the Human Genome Project, analysis time has been reduced from years to just a few hours. For health-conscious people, this means direct access to valuable information. For example, you can find out whether you are among the approximately 15% of Germans with a predisposition to lactose intolerance or whether you could be affected by a vitamin D deficiency, which applies to up to 70% of the population. Internal studies at mybody-x show that around 40% of customers who had reached a plateau in their weight loss discovered genetic causes through the test.

With this knowledge, you can finally stop fumbling in the dark. Instead, you can build your health on a solid, scientific foundation.

Which method reads your genes? A comparison

When you explore your DNA, you inevitably encounter the term gene sequencing. But what does it actually mean? There is no single method for reading your genetic code. Different techniques are used depending on the objective. Let’s clarify which methods are available and why we at mybody-x rely on one particular approach.

Imagine your genome as a vast library. You could read every single book from the first page to the last—or specifically select only the volumes that contain the answers to your questions. Gene sequencing works in much the same way.

From Sanger to NGS—a technological quantum leap

The journey began in the 1970s with Sanger sequencing. At the time, it was a genuine breakthrough that made it possible to decipher the sequence of letters in our DNA for the first time. The process was precise, but also incredibly slow and expensive—comparable to copying a book by hand. It was the method of choice for decoding the first human genome, but it is unsuitable today for fast, practical analyses.

That is why Next-Generation Sequencing (NGS) is now the gold standard. It is the technology we also use at mybody-x. Unlike the Sanger method, NGS reads millions of DNA segments simultaneously. Imagine it as scanning and digitally assembling entire pages at once rather than reading word by word. This makes NGS extremely fast, efficient, and significantly more cost-effective.

The graphic from the Max Delbrück Center impressively illustrates how rapidly the technology has developed.

You can clearly see the leap from the complex Sanger method to today’s powerful NGS platforms. This advancement is what makes analyses like those from mybody-x possible in the first place.

Complete, focused, or targeted—the three approaches to NGS

There are also different strategies within modern NGS. The main difference lies in the level of detail and the focus of the analysis. Here is an overview of the three most important ones:

• Whole Genome Sequencing (WGS): This is the complete analysis. Your entire genome is decoded here—meaning all around three billion DNA building blocks. This method is extremely comprehensive, but also very expensive and produces a vast amount of data. It is used primarily in research or to identify the causes of rare, complex hereditary diseases.

• Whole Exome Sequencing (WES): This method focuses on the exome. These are the approximately 1–2% of your DNA that contain the blueprints for all the proteins in your body. Since most known disease-relevant genetic changes are located in this area, WES is an important tool for medical diagnostics.

• Targeted Sequencing (targeted sequencing): With this approach, we deliberately examine only predefined genes or gene regions. It is a targeted search for the chapters in your “gene book” that are relevant to a specific question—for example, how your metabolism works or which nutrients are particularly important for you.

This table summarizes the key differences between sequencing methods to give you a quick overview.

Comparison of sequencing methods

This table compares the most important gene sequencing methods in terms of their application, cost, and level of detail to give you a clear understanding of the differences.

Method	Focus	Typical application at mybody-x	Advantage
Sanger sequencing	Individual, short DNA sequences	Historical/research use (not for our tests)	Very high accuracy for small regions
Whole Genome Seq. (WGS)	The entire genome (~100%)	Not used	Maximum depth of information (research, rare diseases)
Whole Exome Seq. (WES)	Protein-coding regions (~1–2%)	Not used	Efficient focus on most disease-relevant genes
Targeted Sequencing	Specific, relevant gene regions	Standard for all our DNA tests	Fast, cost-effective, and focused on actionable results

As you can see, the most comprehensive method is not always the best. It all depends on the question.

For lifestyle and nutrition questions, Targeted Sequencing is the smartest approach. You get precise answers to your questions without being overwhelmed by a flood of information that is irrelevant to your everyday life or could cause you unnecessary concern.

That is precisely why we at mybody-x chose this targeted approach. Instead of scanning your entire genome, we analyze exactly the gene variants that have been proven to influence your metabolism, nutrient utilization, or athletic predisposition. This enables us to provide you with clear, practical recommendations that you can put into action immediately.

If you would like to explore in greater depth how our analysis works, you can find all the details in our guide to how genetic tests work.

Ultimately, the choice of method always depends on the objective. And if your goal is to optimize your health and lifestyle, then taking a targeted look at the relevant markers is exactly the right approach.

How we protect your genetic data

The thought of entrusting perhaps the most personal information—your DNA—to a company can initially feel unsettling. That is completely normal. That is precisely why we want to show you openly how reputable providers like mybody-x handle your sensitive data. Because one thing is clear: Your security is our top priority. Only then can you comfortably use the fascinating insights from gene sequencing for yourself.

Your sample is pseudonymized immediately

The most important protective measure takes effect as soon as your saliva sample arrives at the laboratory: pseudonymization. What does that mean? Quite simply: Your sample is immediately separated from all personal details, such as your name or address. Instead, it is assigned a unique, anonymous code—a number that belongs only to you.

For laboratory staff, your sample is now only this code. No one conducting the analysis can identify you from it. Only at the very end, when your completed report is securely transferred to your password-protected customer account, is the code linked to you again—and even then, it is visible only to you.

This process ensures that your genetic data is never openly linked to your name during analysis. It is the gold standard for data protection in the laboratory and a core requirement of the General Data Protection Regulation (GDPR).

Strict rules that give you control

Compliance with the GDPR goes without saying for us. For you, this means a range of safeguards that protect your data to the highest standards and give you full control.

These principles are non-negotiable for us:

• Purpose limitation: Your data will be used exclusively for the purpose you have consented to—namely, creating your report. If we would like to use data for research, we will ask you separately, and you can decide voluntarily.
• No sharing with third parties: Your personal and genetic data are never sold or shared with insurance companies, employers, or other businesses. They belong solely to you.
• Data minimization: We collect and process only what is truly necessary for your analysis. No more and no less.
• Secure disposal: Your biological sample—that is, your saliva—is professionally destroyed after analysis. We do not store it or use it for other purposes.

Technical security behind the scenes

In addition to these legal safeguards, a whole range of technical and organizational measures ensures security. These include modern encryption technologies, strict access controls for laboratories and IT systems, and regular data protection training for all employees.

Together, all of this creates a robust protection concept so that you can feel safe. If you would like to explore the topic in greater depth, you can find more details in our article on data protection for genetic tests in Switzerland. This allows you to focus fully on what really matters: the exciting insights into your health.

Frequently asked questions about gene sequencing

The world of genes is incredibly fascinating, but of course it also raises questions. We have collected the most frequently asked questions for you and answer them openly here. This gives you the confidence you need to take your health into your own hands.

How reliable are the results of an at-home DNA test?

A thoroughly justified question. The answer lies in the quality of the entire process, from start to finish. Reputable providers like mybody-x work exclusively with ISO-certified specialist laboratories in Germany, which must adhere to the strictest quality standards. They use state-of-the-art technology such as Next-Generation Sequencing (NGS), which enables extremely accurate analysis of your DNA building blocks.

The analysis itself is not mere speculation; it is based on a broad scientific body of evidence. Every gene variant we examine has been scientifically validated. This means that its influence on metabolism, nutritional needs, or other physical characteristics has been demonstrated in research. It is this combination of certified laboratory work, cutting-edge technology, and scientific rigor that ensures the high accuracy and reliability of your results.

Can my DNA change over the course of my life?

We hear this question often, and it can easily lead to misunderstandings. Your basic DNA sequence—that is, the exact order of the building blocks A, T, C, and G—is like your personal blueprint. This blueprint is stable and does not change throughout your life. It is determined in you from birth.

What can indeed change, however, is the activity of your genes. And this is precisely where epigenetics comes into play.

Imagine your DNA as a vast library. The books inside—your genes—always remain the same. But your lifestyle, including your diet, exercise, sleep, and stress, determines which books are opened and read and which remain closed on the shelf. Your behavior therefore directly influences how your genes are “used.”

A mybody-x DNA test shows you your genetic blueprint. Our recommendations then help you positively influence your gene activity through your lifestyle.

What happens if a predisposition to a disease is discovered?

This is where we need to be very clear. mybody-x DNA tests are not medical diagnostics, but purely lifestyle products. We focus exclusively on gene variants related to modifiable areas such as your metabolism, nutritional needs, or athletic predisposition.

We do not analyze genes associated with the risk of incurable diseases. If your analysis indicates genetic predispositions that you can positively influence through an adjusted lifestyle (for example, an increased need for certain vitamins), we show you specific, actionable steps. Our goal is to provide you with tools for prevention and self-optimization—not to diagnose diseases.
