Keeping Your Gut Healthy—Your Guide for 2026

Do you often feel tired, bloated or struggle with skin problems? The answer could lie directly in your gut. The good news is that keeping your gut healthy is not rocket science. It is about understanding your microbiome’s needs and deliberately supporting it through the right everyday choices. If you want to interpret your body’s signals correctly, a targeted test from mybody-x can help you gain clarity.

Why your gut is the foundation of your well-being

When you think of your gut, digestion is probably the first thing that comes to mind. That is true, but it is only the tip of the iceberg. Your gut is so much more—it is the pulsing center of your health, a complex ecosystem that fundamentally influences your overall well-being.

Simply imagine your gut as a flourishing, diverse garden. Trillions of microorganisms—bacteria, viruses and fungi—live in this garden and together form your gut microbiome. These tiny helpers work around the clock for you, often unnoticed.

A healthy microbiome is like a perfectly coordinated team: It not only helps you extract nutrients from your food, but also produces essential vitamins, trains your immune system and even communicates directly with your brain.

The power of your inner diversity

In this inner “garden,” diversity is the key to success. The more different types of beneficial bacteria live in your gut, the more resilient your body is to pathogens and the more smoothly your metabolic processes function. High diversity is directly linked to a strong immune system, mental balance and a healthy body weight.

Unfortunately, our modern lifestyle often puts this diversity at risk. Constant stress, lack of sleep, certain medications and, above all, an unbalanced diet consisting largely of highly processed foods can disrupt this delicate balance. It is like letting weeds run rampant in a garden—harmful bacteria spread and push out the beneficial helpers.

A look into the past shows the way

Interestingly, historical analyses show how dramatically our microbiome has changed over time. Researchers who examined feces dating back 1,000 to 2,000 years found that our ancestors had a significantly more diverse gut flora. Their varied, extremely fiber-rich diet provided a foundation for countless bacterial species, which likely made them more resilient to many modern diseases of civilization. If you want to explore this topic further, read here what fossilized excrement reveals about the evolution of the gut microbiome.

This knowledge makes one thing very clear: We can regain control. Keeping your gut healthy isn’t a closely guarded secret, but a conscious decision to choose the right “gardening practices” in our everyday lives.

Your gut check: Signs of balance and imbalance

Sometimes it’s difficult to tell whether your gut is balanced. This table will help you quickly determine whether your gut feeling is right or whether it’s time to take a closer look.

Characteristic	Signs of a healthy gut	Possible signs of an imbalance
Digestion	Regular, well-formed bowel movements (1–3 times daily), no pain, and little bloating.	Irregular bowel movements (constipation/diarrhea), frequent bloating, abdominal cramps, and a feeling of fullness.
Energy levels	Consistent energy throughout the day and restful sleep.	Persistent fatigue, lack of energy, and the familiar afternoon slump.
Skin	Clear, healthy skin without recurring problems.	Skin blemishes such as acne, eczema, redness, or a dull complexion.
Immune system	You rarely get sick and recover quickly from infections.	High susceptibility to infections, frequent colds or inflammation.
Mental well-being	Balanced mood and good ability to concentrate.	Mood swings, difficulty concentrating, “brain fog.”
Food	You tolerate a wide variety of foods well.	Sudden-onset intolerances or sensitivities to certain foods.

This table is a first guide. If you find yourself more often on the right-hand side, these are important signals from your body that you shouldn’t ignore. A mybody-x test (e.g., a microbiome or food intolerance test) can help you understand the causes behind these symptoms.

If you’d like to delve even deeper into the fascinating connections, we recommend our article on the fundamental importance of gut health.

The best part is: You have it in your own hands. In the following sections, we’ll show you exactly how targeted changes to your diet and lifestyle can help you restore your inner balance.

The right diet as fuel for your gut

What ends up on your plate directly determines which bacteria gain the upper hand in your gut. Imagine that you are the head chef for trillions of tiny but extremely important employees in your body. Every meal is an instruction that determines whether the diligent helpers or the lazy troublemakers are encouraged.

It's about choosing the foods your beneficial gut bacteria love and that help them multiply. By consciously adjusting your diet, you can actively shape your microbiome and thereby keep your gut healthy.

Fiber: the superheroes of your gut

If there is a superfood for your gut flora, it's fiber. These are indigestible plant fibers that do not provide your body with direct energy, but are a veritable feast for your beneficial gut bacteria. They ferment the fibers and produce short-chain fatty acids such as butyrate—a substance that has anti-inflammatory effects and strengthens the intestinal lining.

The German Nutrition Society recommends that adults consume around 30 grams of fiber every day. Unfortunately, the reality often looks different, as many people fall far short of this goal. A low-fiber diet can negatively alter the gut microbiome, while a varied, fiber-rich diet has been shown to lead to a greater diversity of beneficial bacteria, which may help prevent disease. You can learn more about the facts surrounding gut health on websites such as AOK, which explores these important connections.

How can you reach those 30 grams in everyday life? It's easier than you think:

• Whole grains instead of white flour: Replace white bread, white pasta, and white rice with their whole-grain alternatives.
• Include legumes: Lentils, chickpeas, and beans are true fiber powerhouses. Add them to salads and soups, or use them as a base for vegetarian burgers.
• Nuts and seeds as a snack: A handful of almonds, walnuts, or a spoonful of chia seeds in your muesli are simple upgrades for in between meals.
• Vegetables with every meal: Aim to fill half your plate with colorful vegetables.

Prebiotics and probiotics: the dream team

Within dietary fiber, there is a special group called prebiotics. These are specific fibers that specifically promote the growth of beneficial bacteria such as bifidobacteria and lactobacilli.

You can find plenty of them in foods such as:

• Chicory and artichokes
• Onions, garlic, and leeks
• Bananas (especially when they are still slightly green)
• Potatoes, pasta, or rice that have cooled down (this is where resistant starch forms)

Probiotics, on the other hand, are the living microorganisms themselves. You consume them through fermented foods, and they settle directly in your gut. They are, so to speak, the new inhabitants of your inner garden.

Prebiotics are, so to speak, the “food,” while probiotics are the “good bacteria” themselves. For a healthy gut, you need both: a good foundation to feed the existing inhabitants and a regular supply of new, beneficial cultures.

Classic probiotic sources include:

• Plain yogurt and kefir
• Sauerkraut ( 꼭 unpasteurized)
• Kimchi and miso
• Kombucha

By combining both—for example, natural yogurt (probiotics) with oats and banana (prebiotics)—you create the perfect conditions for a thriving gut flora. If you are unsure which foods are best for you personally, a mybody-x microbiome test can provide targeted recommendations.

The enemies of your gut: sugar and highly processed foods

While fiber nourishes your beneficial bacteria, there are also foods that have exactly the opposite effect. Sugar and highly processed products primarily feed undesirable bacteria and yeasts. This can lead to so-called dysbiosis, an imbalance in the microbiome.

These “villains” are often hiding where you least expect them: in ready-made meals, sweetened drinks, baked goods, and many snacks. They promote inflammation in the body, burden your immune system, and can worsen digestive problems such as bloating and a feeling of fullness.

A gradual approach is most effective here. No one has to give up everything overnight. Start by making conscious choices and reading labels. Replace a sugary soda with unsweetened tea or water with lemon. Cook one more meal yourself each week instead of reaching for a frozen pizza.

Every small reduction in sugar and processed ingredients is a victory for your gut. If you want to delve deeper into the subject and get specific tips on changing your diet, you can find more valuable information in our guide on Building a healthy gut flora with the right diet.

A gut-friendly day in practice

So what does all this look like in everyday life? Here is a simple example that shows how delicious and uncomplicated a gut-healthy diet can be:

• Breakfast: A bowl of oatmeal with plain yogurt, topped with a handful of berries, a spoonful of flaxseed, and a few walnuts.
• Lunch: A large mixed salad with chickpeas, quinoa, bell pepper, cucumber, and a dressing made with olive oil and lemon. Served with a slice of whole-grain bread.
• Dinner: Pan-fried salmon fillet with a large portion of roasted vegetables (broccoli, carrots, zucchini) and a side of the potatoes left over from the previous day, served chilled.
• Snack: An apple with a small handful of almonds or a carrot with hummus dip.

This plan is packed with fiber, prebiotics, and healthy fats. If you still experience problems despite eating this way, a mybody-x intolerance test could reveal whether some of these healthy foods are not personally optimal for you.

More than just food: How to make your gut happy with the right lifestyle

A gut-healthy diet is absolutely essential, no question. But if you focus only on what is on your plate, you often overlook the real game changers for your gut well-being. Your lifestyle—how you deal with stress, your sleep, and your physical activity—has a tremendous, often underestimated impact on your microbiome.

These are not side issues, but central levers. When you start consciously shaping these areas too, you create an environment in which your gut not only survives but truly thrives. This helps your body get inflammation under control and protect the sensitive balance of your gut inhabitants.

The gut-brain axis: When your mind stresses your gut

Have you ever heard of the gut-brain axis? Think of it as a direct data highway between your brain and your digestive tract. This connection is why stress is felt not only in your head, but often first in your stomach.

Chronic stress puts your body into a state of constant alert. As a result, it releases the hormone cortisol, which can slow down your entire digestive system. Blood flow to the intestines is reduced, digestion slows, and the composition of your valuable gut bacteria can change negatively. You may know the result: abdominal cramps, a bloated stomach, or the typical symptoms of irritable bowel syndrome. Your gut reacts directly to your mental tension.

Fortunately, you can break this negative cycle with simple techniques that are easy to incorporate into everyday life:

• Take mindful breathing breaks: Take just three minutes several times a day. Inhale deeply through your nose for four seconds, hold your breath for four seconds, then slowly exhale through your mouth for six seconds. This immediately signals to your nervous system that the danger has passed and it can relax.
• Short offline moments: Go outside for five minutes, consciously look out the window, or simply listen to the silence. Even these tiny breaks from the screen help reduce mental pressure.
• Use mindfulness apps: Guided meditations for a few minutes a day are perfect for calming your stream of thoughts and reconnecting with yourself.

Remember: Stress reduction is not a luxury but active gut care. Every minute you invest in your mental relaxation is a direct deposit into your health account in your gut. A mybody-x hormone test can show you how stress affects your cortisol levels.

Sleep: The nighttime repair workshop for your gut

While you sleep, your body is working at full capacity—especially your gut. At night, your intestinal lining regenerates, this incredibly important barrier that protects your body from harmful substances. Your body needs sufficient deep, restorative sleep for these essential repair processes.

Sleep deprivation, on the other hand, throws the entire process out of balance. Studies show that just a few nights of poor sleep are enough to reduce the diversity of your gut bacteria and trigger inflammation-promoting processes.

You can do something right away for better, gut-friendly sleep:

• Set regular bedtimes, including on weekends, to stabilize your internal clock.
• Avoid heavy meals and alcohol shortly before going to bed.
• Ensure a dark, cool, and completely quiet sleep environment.
• Keep your smartphone and other screens out of the bedroom for at least an hour before going to sleep.

Exercise brings diversity to your gut

Regular exercise is another fantastic booster for your microbiome. And no, you don't have to run a marathon. Even moderate but regular activity has a demonstrably positive effect. It not only stimulates bowel movements and prevents constipation, but also specifically promotes the diversity of your beneficial bacteria.

The trick is to find a form of exercise you genuinely enjoy so that you’ll stick with it over the long term. Whether it’s brisk walks, a bike ride, yoga, or dancing in your living room—every form of movement counts. The goal is to get your circulation going and gently massage your gut without putting your body under additional stress through extreme exercise.

The influence of medication on your gut flora

Finally, there’s one important point to consider: the influence of medication. Antibiotics in particular can have a massive impact on your microbiome. They are often lifesaving, but unfortunately cannot distinguish between good and bad bacteria. The result is often a virtual clear-cutting of your gut flora.

If you need to take an antibiotic, be sure to talk to your doctor or pharmacist about supportive measures. A targeted intake of probiotic foods such as kefir or unsweetened yogurt, along with prebiotic-rich fiber, can provide significant support for your gut during and after treatment. A mybody-x microbiome test can show you exactly where gaps have developed in your gut flora after such treatment, so you can specifically replenish them.

When a test provides the crucial answers about your gut

Does this sound familiar? You really make an effort, dutifully eat your vegetables, go for walks, and try to keep your stress under control. And yet, you often feel bloated, are inexplicably tired, or notice that you’re suddenly reacting to foods you used to tolerate without any problems. When the usual advice leads nowhere, it may be time to take a closer look.

This is where general guesswork ends and a personalized approach begins. Instead of trying the next diet or a new dietary supplement on a whim, a targeted test can finally give you the clarity you’re looking for. Think of it as an individual map of your body that shows you the most direct route to feeling well.

When “eating healthy” is simply no longer enough

It’s a frustrating scenario that many people know all too well: You fill your plate with even more vegetables, whole grains, and probiotic yogurt, but your stomach continues to rumble regardless. You may even feel that certain “healthy” foods like apples, onions, or legumes make things even worse.

This is a classic moment when a mybody-x intolerance test can be a real revelation. It precisely analyzes how your immune system reacts to a wide range of foods. This helps you find out whether an undiscovered sensitivity or intolerance, for example to fructose, lactose, or histamine, is behind your symptoms.

A test does not replace a medical diagnosis, but it gives you an extremely valuable, personalized indication. You learn which foods you should temporarily avoid to give your gut a much-needed break, instead of unknowingly continuing to irritate it.

A look into your inner ecosystem: the microbiome

Another common problem: You constantly feel drained, your immune system seems to be permanently asleep, or your skin is acting up, even though all standard blood values are within the normal range. The cause could be hidden deeper—namely, in the composition of your gut flora.

A gut microbiome analysis from mybody-x gives you a fascinating insight into the world of your gut bacteria. The test shows you specifically:

• The diversity of your “inner garden”: Is it colorful and species-rich, or does it resemble a barren monoculture?
• The balance: Is there harmony between the beneficial helpers and potentially harmful bacteria, or is there an imbalance (dysbiosis)?
• Specific weaknesses: Could you be lacking important bacterial strains responsible, for example, for producing anti-inflammatory butyrate?

With these results, you do not get vague tips, but clear, personalized recommendations for action. You learn which prebiotic fibers you should specifically eat to nourish the beneficial bacteria that are lacking, or whether taking a particular probiotic really makes sense for you.

Even with simple signs such as stress, you can learn to respond correctly, which directly affects your gut. The following decision tree provides an initial, simple guide.

This graphic makes it clear how closely your mental state and your body’s needs are linked—a crucial first step toward holistic gut health.

Nutrients in short supply – despite a healthy diet

A disrupted gut flora can cause more than just direct symptoms like bloating. It can also sabotage the absorption of vital vitamins and minerals from your food. So you may be eating a nutrient-rich diet, but the valuable substances simply do not reach where they are needed.

Persistent fatigue, difficulty concentrating, or a high susceptibility to infections can be clear signs of such a nutrient deficiency, even if your diet looks perfect on paper.

A mybody-x nutrient test can provide the crucial missing pieces here. It precisely measures your levels of key nutrients such as vitamin D, B12, iron, or magnesium. Combining these findings with those from a microbiome analysis gives you a complete picture: you see not only whether a deficiency exists, but also understand why it may have developed. This allows you to address both issues—targeting the deficiency and resolving the underlying cause in your gut.

The path to clarity is easier than you think

The idea of taking a test may seem time-consuming at first. But mybody-x home tests are designed to make the process as easy as possible. Simply order the right kit online, collect the sample (a small blood, stool, or saliva sample, depending on the test) conveniently and discreetly at home, and send it to the laboratory free of charge.

Within a few days, you’ll receive your detailed yet easy-to-understand report in your personal online portal. Instead of confusing medical jargon, you’ll get clear explanations and, above all, actionable recommendations for your diet and lifestyle. If you’d like to learn more about the different testing options and find out which one is best for you, our overview of mybody-x gut tests contains all the important information.

A test is not a miracle cure, but it is an incredibly powerful tool. It puts an end to guesswork and gives you back control, so you can finally make informed decisions about your health—based on what your body really needs.

The hidden consequences of radical diets for your microbiome

Honestly, who hasn’t dreamed of losing a few kilos in record time? The promises of crash diets are simply too tempting. But while the number on the scales may drop for a brief moment, your gut often pays a high, invisible price.

These radical diets are a real shock to your finely balanced inner ecosystem. It’s not just about missing vitamins. They directly attack the diversity and stability of your gut flora. Understanding this is the key to keeping your gut healthy and finally achieving your ideal weight in the long term.

How a crash diet starves your microbiome

Imagine taking your gut’s colorful, diverse menu and reducing it overnight to an extremely meager diet. That is exactly what happens with a radical calorie-restricted diet. Your beneficial gut bacteria, which depend on a broad range of fiber, are literally deprived of their food source.

The consequences are dramatic: Bacterial diversity collapses. Important strains that you need for a strong intestinal barrier and a functioning immune system wither away. At the same time, this meager diet creates the perfect environment for more adaptable, often undesirable microbes, which can suddenly spread unchecked.

Your gut is not an enemy you have to defeat by starving yourself. It is your most important partner in weight management. Deliberately weakening it sabotages your long-term success.

The scientific confirmation

What happens inside your body, out of sight, is not abstract theory but hard science. A groundbreaking study by Charité – Universitätsmedizin Berlin investigated exactly this: the effects of a diet containing fewer than 800 kcal per day. The results were alarming: Such a diet fundamentally changed the microbiome, reduced the total number of microorganisms, and led to the proliferation of certain problematic bacteria such as Clostridioides difficile. Particularly striking was the finding that this altered gut flora directly affects energy balance. The full study makes clear how profoundly a diet affects the gut flora.

The yo-yo effect is also a consequence of the gut

Have you ever wondered why, after a radical diet, the pounds often come back faster than before—and sometimes even with a few extra? This notorious yo-yo effect also has its roots in a disrupted microbiome.

Fasting changes your gut flora, favoring bacteria that can extract and store energy from food extremely efficiently. In other words, your body switches to “famine” mode. When you start eating normally again, your gut continues operating in highly efficient storage mode and immediately builds up new fat reserves—for the next “time of need.”

• Reduced diversity: Fewer beneficial bacteria mean poorer metabolism and a weaker intestinal barrier.
• Altered energy intake: Your gut learns to extract and store the maximum amount of energy from very little food.
• Increased hunger: A disrupted microbiome can also throw off the hormones that control your hunger and sense of fullness.

Instead of throwing your body out of balance with extreme diets, it’s much wiser and more sustainable to choose a balanced, high-fiber diet. This feeds your beneficial gut bacteria and creates the foundation for a healthy, stable weight.

If you feel that your digestion has gotten out of balance after previous diets, a mybody-x microbiome test can give you clarity. It shows you the exact state of your gut flora and gives you the tools to specifically rebuild its diversity.

The most frequently asked questions about gut health—our answers for you

Gut health is a huge topic and can sometimes be quite confusing. We know that. That’s why we’ve collected the questions we’re asked most often in everyday life here. Instead of complicated scientific language, we provide clear, honest answers so you know exactly where to start.

How quickly will I really feel a change in my gut?

We hear this question all the time. The honest answer: It depends entirely on you and your body. Some people feel noticeably better after just a few days of changing their diet. The unpleasant feeling of fullness subsides, and bloating decreases—this is often the first positive sign. Your gut microbiome is incredibly adaptable.

But for truly profound changes, such as clearer skin, more energy, or an immune system that no longer constantly lets you down, you need a little more patience. Think in terms of weeks and months, not days. Consistency is key, not a quick sprint.

A mybody-x microbiome test can also show you, after about 3–6 months of targeted dietary changes, in black and white how the composition of your gut microbes has changed for the better.

Do I really have to swallow expensive probiotic capsules?

Not necessarily. You always lay the foundation for a healthy gut through your diet. A varied, high-fiber diet with completely natural probiotic sources is a fantastic start. Think of:

• Plain yogurt and kefir
• Fresh sauerkraut (unpasteurized!) and kimchi
• Kombucha and naturally cloudy apple cider vinegar

However, probiotic capsules can be absolutely worthwhile in certain situations. For example, after antibiotic treatment to specifically rebuild the gut flora, or for very specific symptoms.

The key point is this: Instead of blindly trying random products, you should know what you’re lacking. A mybody-x microbiome test gives you precisely this information. It shows whether you have a deficiency of certain important bacterial strains. This way, you can determine whether targeted supplementation would actually benefit you personally.

I already eat a healthy diet, but I still have digestive problems. What could be causing them?

This is one of the most frustrating, but also most common, experiences people report to us. The reason is usually that “healthy” does not mean the same thing for everyone. There are several traps you can fall into.

Often, it’s the supposedly healthy foods that cause problems: apples, onions, cabbage, or legumes can lead to bloating and pain if you have an undiagnosed intolerance—for example, to fructose or certain types of fiber (FODMAPs). A hidden histamine intolerance also often plays a role.

And then there’s the biggest saboteur of all: chronic stress. It can paralyze your digestion even with the perfect diet. In precisely such a case, it’s important to stop guessing. A mybody-x intolerance test or a microbiome analysis finally gives you clarity about which “healthy” foods may not be the right choice for you personally at the moment.

And what about exercise? Does it really help my gut?

Yes, absolutely! Regular, moderate exercise is a fantastic and often underestimated factor in maintaining a healthy gut. Exercise affects it on several levels.

First, it gets your intestinal peristalsis moving. These are the natural muscle contractions in your intestines that transport food onward. So exercise directly helps prevent sluggish digestion and constipation.

Second, more and more studies show that physical activity increases the diversity of beneficial bacteria in your gut. And you don’t have to run a marathon to achieve this. Regular brisk walks, yoga, swimming, or cycling already have a noticeable effect. Here, consistency is much more important than extreme exertion, which can stress the body again.
