What can you do for a healthy gut? Your honest guide

Do you often feel inexplicably tired, struggle with skin problems, or experience mood swings? If you are looking for an answer to the question “What can you do for a healthy gut?”, the journey does not begin with a one-size-fits-all diet, but with a crucial insight: Your well-being starts in your gut. Your gut is much more than just a digestive organ—it is the hidden center of your overall health.

Why your well-being begins in the gut

Perhaps you know the feeling all too well: After a long day at work, you feel exhausted, unfocused, and in a terrible mood. Many people quickly blame stress or too little sleep. But the real cause often lies much deeper—in your microbiome. This is the vast community of trillions of bacteria in your gut, which has a direct line to your immune system, your energy levels, and even your emotions.

When this delicate ecosystem becomes unbalanced, it can have far-reaching consequences that you may not immediately associate with the gut:

• Constant fatigue: A disrupted gut can hinder the absorption of important nutrients. The result? You feel drained of energy even though you get enough sleep.
• Skin problems: Blemishes, rashes, or a dull complexion are often a reflection of your inner state. Your skin shows what is going on in your gut.
• Mental health: The so-called gut-brain axis is not a one-way street. An imbalanced microbiome can significantly disrupt the production of feel-good hormones such as serotonin, directly affecting your mood.

The path from symptom to solution

Many of us tend to fight only the symptoms—the bloating, the fatigue, the blemishes. But that is like mopping up the water without repairing the leak in the pipe. The truly sustainable approach is to find the cause and address it specifically. This is where a proactive approach begins: understanding your body better and taking responsibility for your health.

The process is actually quite logical: You start with the symptom, analyze the cause, and find your personal solution.

This illustration makes it clear: The first step is always becoming aware of a symptom. This is followed by an in-depth search for the underlying causes, ultimately leading to a customized plan. Generic advice rarely helps here, because you need to understand what your body needs individually.

The first step toward a healthy gut is understanding it. Instead of simply treating symptoms, the goal is to identify your personal triggers. Only then can you take targeted and effective action.

A personalized test from mybody-x.com can be your decisive tool in this process. It sheds light on the situation and gives you not vague guesses but concrete data about the state of your body. This finally gives you the foundation you need to make the right decisions for your health. If you’d like to explore the topic further, you can learn in our article why gut flora is so important and how it affects your body down to the smallest detail.

Where your gut problems really come from

You’ve decided to get to the bottom of your gut problems—great, that’s the most important first step. But before you rush out and buy expensive probiotics, we need to pause for a moment. Because blanket advice such as “Just eat healthier” rarely leads to the desired result. Why? Because it completely ignores the true, highly personal cause of your symptoms.

Your gut is not a simple tube but a complex ecosystem. And what throws this system out of balance is often a combination of several factors, some of which you may not even have considered.

Does this sound familiar? A coffee on the go in the morning, one stressful appointment after another at the office, a quick meal from the cafeteria at lunchtime, and in the evening you’re simply too exhausted to cook something fresh. This modern daily routine is pure stress for your gut and one of the main causes of discomfort. Yet often it’s the insidious enemies we underestimate most.

Stress: The direct attack on your intestinal barrier

Chronic stress is much more than just a feeling of being overwhelmed. It puts your body into a constant state of alarm. The result: Your body continuously releases the stress hormone cortisol, which can directly attack the protective mucus layer of your intestinal wall.

Imagine this protective layer as a bouncer. Cortisol can bribe this bouncer, causing the connections between the intestinal cells to loosen. Doctors call this condition “Leaky Gut” or “increased intestinal permeability.”

Suddenly, undigested food particles, toxins, and bacteria can enter your bloodstream uncontrollably. Your immune system sounds the alarm and responds with inflammation throughout your body. You then feel this as bloating, unexplained fatigue, skin problems, or new food intolerances.

Diet as an accelerant

Highly processed foods, sugar, and artificial sweeteners are the second major problem area. While the fiber from vegetables feeds your beneficial gut bacteria, sugar and white-flour products feed precisely the wrong inhabitants in your gut.

• Sugar: It is the favorite food of yeasts such as Candida and promotes the growth of bacteria that can literally fuel inflammation.
• Artificial sweeteners: Studies show that sweeteners such as aspartame and sucralose can negatively alter the composition of the gut flora and may even contribute to glucose intolerance.
• Processed foods: Emulsifiers in ready-made meals, preservatives in processed meats, and baking agents can directly attack your gut’s sensitive mucous layer.

You’re not alone with your symptoms. A 2022 analysis by KKH Kaufmännische Krankenkasse shows an alarming trend: Young women between the ages of 20 and 24 in particular are increasingly suffering from digestive disorders. Here, more than one in five women (22%) sought medical help. You can read more about the alarming figures in the KKH press release.

The Hidden Enemies of Everyday Life

Alongside stress and diet, other factors often unknowingly sabotage your gut balance. Medication—especially antibiotics—is a major one. They can save lives, but unfortunately they don’t distinguish between good and bad bacteria and can throw your microbiome out of balance for months or even years.

Lack of exercise is another factor that many people underestimate. Regular, moderate exercise stimulates intestinal activity, improves circulation, and naturally supports healthy digestion.

As long as you don’t know the true causes of your problems, your efforts often remain a frustrating guessing game. You try one diet after another without knowing that an undiscovered intolerance or a very specific imbalance in your bacteria may be the actual problem.

This is exactly where a personalized approach makes all the difference. Instead of continuing to grope in the dark, an analysis such as the mybody-x.com gut microbiome test gives you a clear picture of the state of your gut. It shows you in black and white which bacterial strains predominate, whether inflammation markers are elevated, and how your gut barrier is doing. With this concrete data, you can finally take targeted action instead of merely treating symptoms.

How to eat for a happy gut

Without question, your diet is the most powerful tool you have for actively managing your gut health. What you eat determines which bacteria feel at home and multiply in your microbiome. But don’t worry: A gut-friendly diet doesn’t mean you have to snack on nothing but celery sticks from now on and give up everything you enjoy. It’s about smart, sustainable adjustments that make a huge difference.

The thought of completely overhauling your diet can quickly become overwhelming. That’s why we’re focusing on small but highly effective steps that can be effortlessly incorporated into your daily routine.

The Magic Number 30 for Your Microbiome

Forget complicated diet rules for a moment. If you want to remember just one thing, let it be this: Try to eat 30 different plant species per week. This simple rule is a real game-changer for your gut flora.

Why is that? Because diversity on your plate directly leads to diversity in your gut. Each plant species provides different fibers, vitamins, and phytonutrients that serve as food for a broad range of beneficial gut bacteria.

That may sound like quite a lot at first, but it’s easier to put into practice than you might think. “Plants” includes all of the following:

• Vegetables
• Fruit
• Legumes (beans, lentils, chickpeas)
• Whole grains (oats, quinoa, rye)
• Nuts and seeds
• Herbs and spices

Each variety counts as one point. An apple is one point, and a handful of almonds is another. Sprinkle sunflower seeds over your salad, and you’ve already collected the next point. A simple nut mix as a snack can already earn you 5–6 points in a single day.

This diversity is crucial. Digestive health is a widespread concern in Germany: Every year, around 2.4 million people across the country are hospitalized due to diseases of the digestive tract. At the same time, 60 percent of respondents reported suffering from digestive problems in 2024. The goal of eating 30 plants per week is a scientifically grounded approach to specifically strengthen microbiome diversity and counteract this issue.

Prebiotics and Probiotics: Your Gut Dream Team

To make this even more tangible, we need to understand two important terms: prebiotics and probiotics. Simply imagine your gut as a garden.

Probiotics are essentially the “good seeds”—live microorganisms that you add to your gut. They settle there and help maintain balance. You’ll find them primarily in fermented foods.

Prebiotics are the “fertilizer” for these seeds. They are indigestible fibers that serve as food for the beneficial bacteria already living in your gut and help them multiply.

A healthy gut needs both: new, beneficial bacteria (probiotics) and the right food for them to develop a strong and diverse community (prebiotics).

Here are some of the best sources of both:

• Top probiotics for your meal plan:

  • Plain yogurt & kefir: Look for products without added sugar.
  • Sauerkraut (unpasteurized): Only raw sauerkraut from the refrigerated section contains live cultures.
  • Kimchi: Fermented Korean cabbage, a true bacteria powerhouse.
  • Kombucha: A fermented tea drink—a great alternative to soft drinks.
  • Miso: A Japanese seasoning paste made from fermented soybeans.

• Top prebiotics (the best food for your bacteria):

  • Onions, garlic & leeks: The foundation of so many savory dishes.
  • Artichokes & asparagus: Particularly rich in the prebiotic inulin.
  • Bananas (especially those that are still slightly green): Contain valuable resistant starch.
  • Legumes: Lentils, beans, and chickpeas are true fiber heroes.
  • Whole grains: Oatmeal is a perfect way to start the day.

A practical tip: Start slowly with these foods, especially if you have previously eaten a relatively low-fiber diet. This gives your gut time to adjust to the new food and helps prevent bloating.

Simple food swaps with a big impact

The change doesn’t have to be radical. Often, it’s the small, intentional swaps in everyday life that bring the greatest long-term success. Here are some examples you can put into practice right away.

Gut-friendly food swaps for your everyday life

This table shows simple swaps for replacing foods that are harmful to the gut with nutrient-rich, gut-friendly alternatives and explains why it is worthwhile.

Instead (Harmful to the gut)	Choose this (Gut-friendly)	Why this swap helps your gut
White bread or toast for breakfast	A bowl of oatmeal with berries and nuts	Provides soluble fiber (prebiotics) that nourish your beneficial gut bacteria and keep you feeling full for longer.
Sugary soft drinks or juice	Water, unsweetened tea, or kombucha	Avoids empty calories and blood sugar spikes that feed harmful bacteria. Kombucha provides probiotics.
A sweet bar as an afternoon snack	A handful of almonds with an apple	Provides healthy fats, protein, and fiber that help keep blood sugar stable and promote diversity.
Durum wheat pasta	Whole-wheat pasta or lentil/chickpea pasta	Increases the fiber and protein content of your meal and supports healthy digestion.
Ready-made salad dressing	A simple dressing made with olive oil, vinegar, mustard & herbs	Avoid emulsifiers, sugar, and additives that can damage the gut barrier.

These simple changes are an excellent start. But what if you continue to experience symptoms despite eating a healthy diet? What if you follow all the tips, but bloating, fatigue, or skin problems simply refuse to go away?

Here’s a crucial point: “Healthy” doesn’t mean the same thing for everyone. A food that benefits most people can personally become a problem for you. Undetected food intolerances are often the hidden saboteurs on the road to a healthy gut.

An intolerance test from mybody-x.com can finally provide clarity. It analyzes how your immune system reacts to hundreds of foods. This helps you find out whether supposedly healthy foods such as almonds, tomatoes, or oats may be triggering a low-grade inflammatory response in your body. With this knowledge, you can adjust your diet strategically and finally eliminate the real culprits instead of continuing to grope in the dark. If you’d like to learn more about which foods really help with digestive problems, you’ll find more valuable tips from us.

More than just food: Your lifestyle as the key to gut health

You’ve changed your diet, dutifully eat fiber, and avoid sugar, but somehow you still don’t feel truly fit? It’s a frustrating feeling that many of us know. Often, the reason isn’t on your plate but hidden in your everyday life.

A gut-friendly diet is absolutely the foundation. But if you’re constantly under pressure, barely sleep, or spend all day sitting at a desk, you’re sabotaging your own efforts. Imagine building a beautiful house (your diet), but its foundation (your lifestyle) is unstable. That can’t work in the long run. Your gut reacts extremely sensitively to stress, lack of sleep, and exercise—or rather, the lack of it—often even more strongly than to what you eat.

Less stress, better digestion: Calm your gut-brain axis

Have you ever suddenly had stomach rumbling before an important meeting? That’s no coincidence—it’s your gut-brain axis at work. This direct nerve connection between your head and your gut is not a one-way street. Ongoing stress in your mind puts your gut on high alert. Your body releases cortisol, which can make the sensitive intestinal barrier leaky (leaky gut) and fuel low-grade inflammation.

The good news is: You are not helplessly at the mercy of this cycle. You can actively break it. Often, tiny, mindful breaks are all it takes to calm your overstimulated nervous system and give your gut a well-deserved breather.

A simple 5-minute breathing exercise for immediate relaxation:

1. Sit upright or lie down comfortably. Rest one hand relaxed on your abdomen.
2. Slowly inhale deeply through your nose, counting silently to four. Feel your abdominal wall gently rise.
3. Hold your breath briefly, counting to two.
4. Slowly and fully exhale through your mouth, counting to six. Feel your abdomen flatten again.
5. Repeat the entire process for five minutes. Focus only on the sensation of your breath as it comes and goes.

This simple exercise is incredibly effective. It activates the parasympathetic nervous system—the part of your nervous system responsible for “Rest and Digest.” This demonstrably lowers cortisol levels and can immediately relieve acute stomach rumbling.

If you feel that stress is your constant companion, a hormone test from mybody-x.com can be extremely revealing. It measures your daily cortisol profile and shows you in black and white whether your stress level is actually chronically elevated. With this knowledge, you can take targeted action instead of continuing to feel your way in the dark.

Sleep: The nighttime repair workshop for your microbiome

For your gut, sleep is what an overnight deep clean is for a city: absolutely indispensable. Just one night of poor sleep can seriously disrupt the diversity of your gut bacteria and shift the balance in favor of harmful bacteria. Yes, even your gut's little inhabitants have a clear day-night rhythm.

Good sleep is not a luxury but a biological necessity. It is the time when your body fights inflammation, repairs the intestinal barrier, and your microbiome regenerates.

Here are a few practical tips for better sleep hygiene that really work:

• Blue-light detox before bed: The light from your phone, tablet, and other devices blocks the production of the sleep hormone melatonin. Put your devices away at least one hour before going to bed.
• Establish consistent bedtimes: Try to maintain a similar rhythm on weekends as well. This greatly stabilizes your internal clock.
• Create a sleep cave: Your bedroom should be cool and completely dark. The ideal temperature is around 18 degrees Celsius.
• Kitchen closed in the evening: Give your digestive system a break and eat your last large meal at least three hours before going to bed.

Get your gut moving: Gentle activity instead of high-performance sports

Exercise for your gut doesn't have to be a marathon. Quite the opposite: Moderate, regular activity is often much more effective than infrequent, high-intensity workouts that only put additional stress on your body. Exercise stimulates intestinal peristalsis—the wave-like muscle contractions of your intestines—and thus ensures regular “transport.”

Even a simple walk after eating can work wonders. It not only gently stimulates digestion but also helps stabilize blood sugar levels. The goal is not to exhaust yourself completely, but to gently activate your body. Experts recommend at least 150 minutes of moderate exercise per week to strengthen the immune system and promote long-term gut health.

This is more relevant than ever when you consider that stress, lack of exercise, and an unhealthy diet are considered the main causes of gastrointestinal infections. A recent analysis by AOK showed that in 2023, these infections were responsible for a record number of sick notes—one in seven employees was affected. This impressively highlights how important a resilient gut is for our overall health. You can find more information about these alarming figures on the AOK information page.

By firmly integrating these three pillars—stress management, sleep, and exercise—into your daily routine, you create the best possible environment for a healthy microbiome. And the best part? A happy gut gives you back the energy you need for more exercise and a more relaxed daily life. This creates a positive cycle that takes your health to a whole new level.

When a test provides clarity and how mybody-x.com can help

You have changed your diet, are trying to reduce stress, and exercise regularly—but somehow, you simply are not seeing any improvement? When you have reached the point where generic advice no longer helps, it is time for a new approach. Instead of continuing to wonder what your gut might be lacking, the next logical step is to finally find out.

Persistent symptoms are more than just a nuisance. They are clear signals from your body that something is out of balance. If you recognize yourself in one or more of the following points, a test is probably the most effective way to finally gain clarity.

The typical warning signs from your body

Sometimes the signs are subtle, but often they are very clear. Watch for these recurring patterns, which indicate that there may be an underlying problem that cannot be resolved through general measures alone.

• Chronic bloating and persistent abdominal distension: Do you look five months pregnant after eating, even though you only had a salad? That is not normal and often points to dysbiosis or undetected intolerances.
• Unclear food reactions: Do you feel like you can hardly tolerate anything anymore, and do you react to more and more foods with stomach pain, diarrhea, or skin rashes?
• Persistent fatigue and lack of energy: Are you constantly exhausted even though you get enough sleep? A disrupted gut can block the absorption of important nutrients such as iron or B vitamins. A nutrient test from mybody-x.com can shed light on the matter.
• Skin problems such as acne, eczema, or rashes: Your skin is often a reflection of your gut. Chronic inflammation inside the body often appears on the skin.
• Mood swings or mental exhaustion: When the gut-brain axis is disrupted, it can directly affect your mental well-being.

If you are constantly struggling with the same symptoms despite all your efforts, it is time to stop guessing. A test provides facts about the condition of your body, not speculation.

In this case, a test from mybody-x.com is your personal analysis tool. It enables you to take a precise look inside your system and uncover the true causes of your symptoms.

Your path to clarity with mybody-x.com

We deliberately designed the entire process so that you can complete it easily and conveniently from home. No waiting for appointments, no complicated procedures.

First, you simply collect a sample at home. Depending on the test, this may be a small stool or blood sample—just a few drops from your fingertip. Everything you need is clearly explained in the test kit.

You then send your sample free of charge to our ISO-standard-certified partner laboratory in Germany, where it is analyzed using state-of-the-art methods.

But the most important part comes afterward: You don’t receive incomprehensible raw data, but a comprehensive, easy-to-understand results report. It not only shows you where the problems lie, but also gives you specific recommendations tailored to you for your diet and lifestyle.

Imagine discovering through an intolerance test that the “healthy” almonds you eat every day trigger a strong immune response in your body and are the cause of your bloating. Or a gut microbiome test reveals that you lack important bacterial strains responsible for producing the happiness hormone serotonin—one possible explanation for your low mood. If you want to learn more about these possibilities, our article on the gut microbiome test makes for fascinating reading.

Your most important questions about a healthy gut—straight answers instead of myths

The path to feeling better in your gut is often full of questions. You start paying attention to your diet, read about probiotics, and come across countless tips—and in the end, you are more confused than before. At mybody-x.com, we hear every day which questions are weighing on you the most. Here you will find the answers—honest, direct, and based on practical experience—so you know what really matters.

How long does it really take to build up the gut microbiome?

Honestly? Patience is your most important companion here. The idea that you can repair a gut microbiome that has been out of balance for years in just a few days is unfortunately a myth. The regeneration of your microbiome is as individual as you are and depends heavily on where you start.

The good news is that you can often notice the first positive changes, such as less bloating or more reliable digestion, after just two to four weeks of consistently changing your habits. That is the first motivational boost! However, building a truly stable and diverse gut microbiome, especially after antibiotic treatment or in the case of long-term complaints, is more of a marathon. Realistically, allow three to twelve months for this. Consistency is everything. A test from mybody-x.com can help by showing you a clear starting point and enabling you to objectively measure your progress after some time.

Are probiotics from the pharmacy always a good idea?

Not necessarily. Probiotics can be extremely useful, but they are not a cure-all that you should take on a whim. It is a widespread misconception that a “one-size-fits-all” approach using random bacterial strains works. At best, nothing happens; at worst, you may throw your already sensitive ecosystem even further out of balance.

Your gut has very specific needs. The most sensible first step is always to provide your microbiome with the right “fuel” through a varied, fiber-rich diet. If you want to support it more specifically, it is wiser to first find out which microorganisms are actually missing from your gut. A microbiome analysis from mybody-x.com shows you exactly which bacterial strains are underrepresented. With this knowledge, you can choose the right probiotics or fermented foods and avoid investing blindly.

Can my gut really affect my mood?

Yes, absolutely—and to a significant extent. This connection, known as the “gut-brain axis”, is not imaginary but hard science. Your gut is a veritable hormone factory. Did you know that it produces around 95% of the “happiness hormone” serotonin?

An imbalance in your gut flora, known as dysbiosis, can significantly disrupt the production of these crucial messengers. You feel the effects directly: mood swings, inner restlessness, anxiety, or even depressive moods may have their roots in a stressed gut. A healthy gut is therefore one of the most important pillars of your mental well-being.

I eat healthily, but I still have symptoms—what could be causing them?

This may be the most frustrating experience of all—and it’s a problem we hear about incredibly often. You eat avocados, tomatoes, almonds, and eggs—everything considered healthy—and yet your stomach still rumbles, you feel tired, or your skin goes haywire. How can that be?

The answer often lies in undetected IgG-type food intolerances. These are not classic allergies, but delayed immune reactions. Your body reacts to foods that are actually healthy with silent inflammation. Hours or even days later, this can manifest as bloating, headaches, fatigue, or skin problems. So you may be eating “healthily” while unknowingly fueling your symptoms. This is exactly where an intolerance test from mybody-x.com finally provides clarity. It analyzes your body’s reaction to hundreds of foods and gives you clear guidance on which foods are truly good for you and which you should avoid for a while so your gut can calm down.
