Gene sequencing for your health, simply explained
ca. 20 Minuten

Imagine having a kind of user manual for your body that shows you exactly how to improve your health in a targeted way. That's exactly what modern gene sequencing makes possible. It's the key to finally understanding why some diets just 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 so differently to certain foods or types of exercise than other people's bodies do? The answer lies deep within your DNA. Gene sequencing is basically 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 detail and finds the tiny individual variations that make you unique. These variations can influence things like:
- Your metabolism: How efficiently your body processes fats, carbohydrates, and proteins.
- Your nutrient needs: Whether you have a predisposition to deficiencies in certain vitamins or minerals.
- Your physical traits: How your muscles respond to exercise or how quickly you recover after working out.
What once sounded like pure science fiction and was extremely expensive is now accessible to many thanks to rapid technological advances.
The cost of sequencing an entire 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 remarkable 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 lets you 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’ve been wishing for. Instead of generic diet rules, you get personalized recommendations that truly suit your body. Gene sequencing thus becomes your personal tool for achieving your goals - whether that’s losing weight, having more energy, or aging healthily - in an informed and effective way.
This isn’t about searching for incurable diseases. It’s about optimizing your own lifestyle. Your genes aren’t an unchangeable destiny, but a valuable source of information. When you understand how your body is “programmed,” you can adjust your diet and habits to reach your full potential. You can also learn more about what your genes reveal about you in our article on the basics of genetics.
How your genetic code is decoded
So, you’ve decided to take a look at your personal “instruction 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 involved are clear and easy to follow.
Imagine your entire genetic makeup, your genome, as a huge library. This library is packed with books that together make up the complete blueprint for your body. But for your personal analysis, we don’t need to read every single book from cover to cover. Instead, we focus on specific chapters and sentences - precisely the ones that tell us how your metabolism works or how you process certain nutrients.
From the test kit straight to the lab
It all starts simply at home. With the mybody-x test kit, you collect a small saliva sample. It’s 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 the other components in your saliva, such as proteins or bacteria. At 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 key “sentences” in your genetic code, we use a highly advanced method: Next-Generation Sequencing (NGS). You can think of it like this: first, your DNA is broken down into countless small fragments. These fragments are then copied millions of times and read in parallel, or simultaneously.
A powerful computer then reassembles these short sections like a puzzle and compares the result with a human reference genome. This comparison reveals tiny but crucial differences - your individual genetic variants. These variants determine, for example, whether you metabolize carbohydrates better than fats or are predisposed to having higher nutrient requirements.
The entire journey from your saliva sample to your finished health plan can be summed up in three simple steps.

This graphic perfectly illustrates how a simple sample is transformed through scientific analysis into a concrete, personalized plan for you.
Quality and safety come first
The reliability of your results is our top priority. That’s why we work exclusively with ISO-certified specialist laboratories. Every step of the process is subject to the strictest quality controls to ensure that the data we read is completely accurate and reliable.
As soon as your sample arrives at the lab, it is pseudonymized. This means it is immediately separated from your name and personal information and given 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 translate complex genetic information into understandable and, above all, actionable recommendations, which you’ll 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 basis for all of this. If you want to explore the subject in greater depth, you’ll find more fascinating details in our article about the structure of DNA.
Once your analysis is complete, your original saliva sample will be securely destroyed in accordance with regulations. Your genetic data belongs to you alone. 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 theory behind gene sequencing sounds fascinating, but what does it actually mean for you and your everyday life? Enough theory—let’s get practical. Imagine not 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’re 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 have reached your ideal weight yet, 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 offer relates to your metabolism. Many of us have tried all kinds of diets—low-carb, low-fat, intermittent fasting—often with limited success. The reason is actually quite simple: there’s no one diet that works for everyone.
A DNA analysis can reveal what type of metabolism you have. It looks at how your body naturally handles the three major nutrient groups:
- Carbohydrates: Do you use them as a turbocharged energy source, or does your body tend to quickly convert them into fat stores?
- Fat: Are you a “fat type” who uses healthy fats particularly efficiently for energy?
- Protein: How much protein do you personally need to optimally nourish and maintain your muscles?
The mybody® DNA Metabolism Test analyzes these exact genetic markers. The result isn’t a new dietary rule, but a personalized recommendation for the nutrient balance that works best for you.
Imagine discovering that you’re a carb type. Instead of cutting out carbs completely, 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 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 training?
- Risk of injury: Are there genetic indicators 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’ll train more efficiently, prevent injuries, and give your body exactly the rest it really needs.
From knowledge to concrete action
The real strength of gene sequencing lies in turning knowledge into an actionable plan. What good is it to know that you’re predisposed to a particular vitamin deficiency if you don’t know what to do about it?
That’s exactly where mybody-x comes in. We don’t just give you raw data; we turn it into clear guidance:
- Personalized meal plans: You’ll get specific suggestions for meals and foods that suit your metabolism type.
- Personalized nutrient recommendations: You’ll 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 - everything tailored to your genetic profile.
Gene sequencing is no longer a thing of the future in Germany. It has been part of clinical routine since 2010, and projects like the Human Genome Project have reduced analysis times 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’re among the approximately 15% of Germans with a genetic predisposition to lactose intolerance, or whether you may be affected by 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 hit a weight-loss plateau found genetic causes for it through the test. Read more here about the rapid development of sequencing technology.
With this knowledge, you can finally stop groping 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 come across the term gene sequencing. But what does it mean? There isn’t just one method for reading your genetic code. Different techniques are used depending on the goal. Let’s clarify which methods are available and why we at mybody-x use a very specific approach.
Imagine your genome as a huge library. You could read every single book from the first page to the last – or specifically find the volumes that contain the answers to your questions. Gene sequencing works in exactly 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 real breakthrough that made it possible for the first time to decipher the sequence of letters in our DNA. The method was precise, but also incredibly slow and expensive – like copying a book by hand. It was the method of choice for decoding the first human genome, but today it is unsuitable for fast, practical analyses.
That is why Next-Generation Sequencing (NGS) has become the gold standard. It is the technology we use at mybody-x, too. Unlike the Sanger method, NGS reads millions of DNA segments at the same time. Imagine scanning and digitally assembling entire pages at once instead of reading word by word. This makes NGS extremely fast, efficient, and significantly more cost-effective.
The graphic from the Max Delbrück Center impressively shows how rapidly the technology has evolved.
You can clearly see the leap from the laborious Sanger method to today's powerful NGS platforms. This advancement is what makes analyses like those by mybody-x possible in the first place.
Complete, focused, or targeted – the three NGS approaches
There are also different strategies within modern NGS. The main difference lies in the level of detail and the focus of the analysis. Here are the three most important ones at a glance:
-
Whole Genome Sequencing (WGS): This is the complete analysis. Your entire genome is decoded, meaning all around three billion DNA building blocks. This method is extremely comprehensive, but also very expensive and produces a huge amount of data. It is used primarily in research or to find the causes of rare, complex hereditary diseases.
-
Whole Exome Sequencing (WES): This method focuses on the exome. These are the approx. 1–2% of your DNA that contain the instructions for building all the proteins in your body. Since most known disease-relevant genetic changes occur in this area, WES is an important tool for medical diagnostics.
-
Targeted Sequencing: With this approach, we deliberately look only at predefined genes or gene segments. It’s 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 main differences between sequencing methods to give you a quick overview.
Comparison of sequencing methods
This table compares the main gene sequencing methods in terms of their applications, costs, and level of detail, giving you a clear understanding of the differences.
| Method | Focus | Typical use at mybody-x | Advantage |
|---|---|---|---|
| Sanger sequencing | Individual, short DNA segments | Historical/research use (not for our tests) | Very high accuracy for small regions |
| Whole Genome Sequencing (WGS) | The entire genome (~100 %) | Not used | Maximum depth of information (research, rare diseases) |
| Whole Exome Sequencing (WES) | Protein-coding regions (~1-2 %) | Not used | Efficient focus on most disease-relevant genes |
| Targeted Sequencing | Specific, relevant gene loci | Standard for all our DNA tests | Fast, cost-effective, and focused on actionable results |
As you can see, the most comprehensive method isn’t 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 isn’t relevant to your everyday life or might cause you unnecessary concern.
That’s exactly why we chose this targeted approach at mybody-x. Instead of scanning your entire genome, we analyze only the specific gene variants that have been proven to affect your metabolism, how you use nutrients, or your athletic predisposition. This allows us to give you clear, actionable recommendations.
If you’d like to learn more about exactly how our analysis works, you’ll find all the details in our guide to how genetic tests work.
Ultimately, the choice of method always depends on the goal. And if your goal is to optimize your health and lifestyle, then taking a targeted look at the key markers is exactly the right approach.
How we protect your genetic data
The thought of entrusting a company with perhaps your most personal information—your DNA—can feel unsettling at first. That’s completely normal. That’s exactly why we want to show you openly how reputable providers like mybody-x handle your sensitive data. One thing is clear: Your security is our top priority. That’s the only way you can enjoy the fascinating insights from gene sequencing.

Your sample is pseudonymized immediately
The most important safeguard takes effect as soon as your saliva sample arrives at the lab: pseudonymization. What does that mean? It’s simple: Your sample is immediately separated from all personal information, such as your name or address. Instead, it’s assigned a unique, anonymous code. A number that belongs only to you.
From this point on, your sample is identified to lab staff only by this code. No one conducting the analysis can trace it back to you. 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, only you can see it.
This process ensures that your genetic data is never openly linked to your name during analysis. It’s the gold standard for privacy in the lab and a core requirement of the General Data Protection Regulation (GDPR).
Strict rules that put you in control
Compliance with the GDPR is a given for us. For you, that means a set of guarantees 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 consented to—namely, creating your report. If we want to use data for research, we’ll ask you separately, and you can decide whether to participate 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 to you alone.
- Data minimization: We collect and process only what’s truly necessary for your analysis. Nothing more and nothing less.
- Secure disposal: Your biological sample—that is, your saliva—is properly destroyed after analysis. We don’t store it or use it for any other purpose.
Technical security behind the scenes
Alongside these legal safeguards, a 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 strong protection plan so you can feel secure. If you’d like to explore the topic in more depth, you’ll find more details in our article on data protection for genetic tests in Switzerland. That way, you can 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 raises questions too. We’ve collected the most frequently asked questions and answer them openly here. That way, you can feel confident taking your health into your own hands.
How reliable are the results of an at-home DNA test?
An absolutely fair question. The answer lies in the quality of the entire process, from beginning to end. Reputable providers like mybody-x work exclusively with ISO-certified specialist laboratories in Germany that must adhere to the strictest quality standards. They use state-of-the-art technology such as Next-Generation Sequencing (NGS), which enables extremely accurate reading of your DNA building blocks.
The analysis itself is not mere guesswork; it is based on a broad scientific data foundation. Every gene variant we examine has been scientifically validated. This means its influence on metabolism, nutrient 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—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 set in you from birth.
What can change, however, is the activity of your genes. And that’s exactly where epigenetics comes in.
Think of your DNA as a huge library. The books inside—the genes—always stay the same. But your lifestyle—your diet, exercise, sleep, and even stress—determines which books are opened and read and which remain closed on the shelf. So your behavior has a direct impact on how your genes are “used.”
A DNA test from mybody-x shows you your genetic blueprint. Our recommendations then help you positively influence your genes’ activity through your lifestyle.
What happens if a predisposition to a disease is discovered?
We need to make a clear distinction here. mybody-x DNA tests are not medical diagnostics, but lifestyle products only. We focus exclusively on gene variants that affect areas you can influence, such as your metabolism, nutrient needs, or athletic predisposition.
We do not analyze genes associated with the risk of incurable diseases. If your analysis reveals genetic predispositions that you can positively influence through an adjusted lifestyle (for example, an increased need for certain vitamins), we’ll show you concrete, actionable steps. Our goal is to give you tools for prevention and self-optimization—not to diagnose diseases.
Are you ready to make the right decisions for your health based on your unique genetic profile? mybody-x offers you a scientifically grounded path to a better understanding of your body. Discover the right DNA tests at mybody-x.com now and start your journey.
