Which diet suits me and how you can finally find it

The question "Which diet is right for me?" has only one honest answer: the one tailored to your unique body. Standard diets fail so often because they ignore precisely that – your personal biology. The key to success lies in understanding your metabolism, your genes, and your lifestyle, and making them the foundation of your nutrition.

Why the one perfect diet for everyone is a myth

Have you ever wondered why your friend loses weight effortlessly on a low-carb diet, while you just feel tired and hungry? Or why intermittent fasting is a complete success for your colleague, but only triggers cravings for you? This isn't a personal failure, but simple biological reality.

The idea that there is a universal "best diet" is one of the most persistent myths in the world of nutrition. Each of us is a complex, unique system. A diet that ignores this individuality is doomed to failure from the outset.

Your body, your rules

Your body has its own rules. These are determined by your genetic predisposition, your metabolism, and even the trillions of microorganisms in your gut. All these factors determine how efficiently you process certain nutrients.

Imagine your body like a car. Some engines run best on premium gasoline (perhaps fats), others need diesel (more likely proteins), and still others are optimized for regular gasoline (carbohydrates). If you fill up with the wrong fuel, the engine simply won't run smoothly – you'll feel tired, unfocused, and might even gain weight.

The crucial step to lasting success is to stop working against your body. Instead, learn to interpret its signals. A diet shouldn't feel like a constant battle, but rather like an intuitive and supportive partnership.

The limitations of standard concepts

Standard diets like keto, paleo, or veganism are based on general principles. These can work great for a specific group of people, but not for everyone. They often overlook crucial individual differences:

• Genetic predisposition: Your genes can influence whether you are more sensitive to carbohydrates or fats. A so-called "carb type" will likely have less success with a high-fat diet.
• Metabolic rate: Your basal metabolic rate – that is, the amount of energy your body uses at rest – is individual. It influences how many calories you actually need.
• Gut microbiome: The composition of your gut bacteria has a huge influence on how you digest food, absorb nutrients, and how strong your appetite is.
• Lifestyle and preferences: A diet that doesn't fit your daily routine, your budget, or your tastes won't be sustainable for long. It's that simple.

So instead of chasing the next fad diet, it's about taking a step back and focusing on yourself . Understanding the basics of your own biology will allow you to make much better choices. To delve deeper into this topic, our article on personalized nutrition offers valuable insights into how you can put this into practice.

This shift in perspective is the first and most important step towards a way of eating that not only works, but also feels good and benefits you in the long run. In the following sections, we'll show you exactly how to find that out.

Define your starting point and goals realistically

Before you dive headfirst into the world of diets, let's take a crucial step back. You can only answer the question "Which diet suits me?" when you have a crystal-clear understanding of who "you" actually are – what your exact starting point is and where you truly want to go. Without this clarity, any attempt is just a shot in the dark.

A ruthless self-analysis is your compass here. It's about much more than just a number on the scale. It creates a solid foundation that helps you make a decision you'll still be happy with six months from now.

What is your true goal?

Ask yourself honestly: What do you really want to achieve by changing your diet? Weight loss is often just the tip of the iceberg. There are usually much deeper desires behind it that are just as important.

Your goals could include, for example:

• More energy in everyday life: You no longer want to collapse exhausted on the couch after work, but still have energy for your hobbies or your family.
• Improved athletic performance: You want to finally see progress in training, recover faster, or improve your endurance for the next run.
• Getting digestive problems under control: You're tired of constantly dealing with bloating, fullness, or irregularities.
• A clearer complexion: You hope that a targeted diet will reduce inflammation and help your skin regain its glow.
• Long-term health care: You want to actively do something to prevent illnesses and stay fit and vital even in old age.

Define your "why" as specifically as possible. "I want to feel better" is a start, but "I want to be able to play on the floor with my children without joint pain" is a much stronger motivation that will keep you going even on tough days.

Your lifestyle as a reality check

The best nutrition strategy in the world is useless if it doesn't fit into your daily life. Be brutally honest with yourself about your capacity and preferences. This has nothing to do with a lack of discipline, but rather with smart planning.

Just ask yourself these questions:

• Time budget: How much time can and do you realistically want to invest in cooking and preparation each day? Are you more the type for quick 15-minute meals , or do you love spending hours in the kitchen on weekends?
• Cooking skills: Are you a passionate home cook, or are you overwhelmed by anything beyond cooking pasta? Your skills determine how complex the recipes can be.
• Social environment: Do you often eat out, in the canteen, or with your family? A diet must also work in these situations without socially isolating you.
• Budget: How much money do you want to spend on food? Some diets that rely on special products or high-quality organic meat can be quite expensive.

Define the health-related framework

Your body dictates the most important rules. Ignoring health factors can not only hinder your success, but in the worst case, it can even be risky.

Be sure to clarify these points, ideally in a conversation with your doctor or therapist:

• Pre-existing conditions: Do you suffer from diabetes, thyroid problems, high blood pressure, or hormonal disorders? These often require a very specific nutrient composition.
• Intolerances and allergies: Do you have a known lactose intolerance, gluten intolerance, or nut allergy? These foods must be excluded from the plan from the outset.
• Medication: Do you take any medication regularly? Some can affect metabolism or require a very consistent supply of nutrients, which can be difficult with some diets.

To make this process easier for you, we've prepared a short checklist. Use it to clearly define your goals, lifestyle, and health circumstances. It will form the basis of your decision.

Checklist for your personal nutrition strategy

category	Guiding questions for you	Your notes
Main objectives	What is my most important goal (e.g., losing 10 kg , increasing energy, improving digestion)?
lifestyle	How much time do I have per day to cook? Do I eat out often? Do I cook for a family?
Preferences	Which healthy foods do I really enjoy? What can I absolutely not do without?
Health	Are there any known pre-existing conditions, allergies, or intolerances that I need to be aware of?

Once you've reviewed these points, you'll have your personal requirements profile in hand. Instead of wondering which diet is currently trending, you can now specifically examine which nutritional approach suits your needs. And that's precisely the difference between a short-term experiment and a change that truly lasts.

How your metabolism and genes show the way

Imagine no longer having to guess which diet is right for you. Instead, you'd have clear, scientifically sound guidance that comes directly from your own body. Sounds like something from the future? It's not – it's the reality of personalized nutrition.

The reason so many diets fail often lies deep within our biology: in our DNA. Your genes determine not only your hair and eye color, but also how your body processes nutrients. They dictate whether you convert fats or carbohydrates more efficiently into energy.

The genetic blueprint of your metabolism

Each of us has an individual metabolic type, which is genetically determined. This explains why some people thrive on a low-carb diet, while others feel lethargic and simply can't get going without carbohydrates.

This genetic code influences a whole range of factors:

• Macronutrient utilization: How efficiently your body uses proteins, fats, and carbohydrates for energy.
• Satiety feeling: How quickly you feel full and how strongly your body reacts to the corresponding hormones.
• Predisposition to being overweight: Whether you have a genetic predisposition to storing fat.
• Response to exercise: Which type of training – endurance or strength – is most effective for your body to burn fat.

A standard diet that completely ignores these individual differences is like trying to open a lock with the wrong key. It simply doesn't fit.

How to decipher your metabolic type

Instead of groping in the dark and trying one diet after another, you can now go directly to the source: your DNA. Modern DNA metabolic tests, such as the mybody® DNA Test , use a simple saliva sample to analyze your genetic predispositions.

This is not hocus-pocus, but applied science. Your saliva contains your unique DNA, which is examined in the laboratory for specific gene variants – precisely those genes known to control the metabolism of fats, carbohydrates, and proteins.

The result is a kind of personal manual for your body. You'll learn in black and white what your metabolic type is and receive clear, actionable recommendations based on your individual genetics.

Such a test can show you, for example, whether you are a so-called " fat-protein type ." For you, a diet rich in healthy fats and high-quality proteins would be ideal, while you should reduce your carbohydrate intake. Or perhaps you are a "carbohydrate type" who needs whole grains, fruits, and vegetables to feel energized and satisfied.

Personalized nutrition is key

This scientific approach takes the guesswork out of the question "Which diet is right for me?". Instead of blindly following trends, you gain clarity about what your body truly needs.

A real-life example: Anna tried to lose weight for years with a low-carb diet. Despite strict discipline, she constantly felt tired, and the scale barely budged. After a DNA test, she discovered that she has a balanced metabolic type that needs complex carbohydrates. With this knowledge, she changed her diet—more oatmeal, quinoa, and legumes—and suddenly the pounds melted away, while her energy returned.

These findings are extremely valuable:

1. You make deliberate decisions: Instead of blindly following trends, you choose a diet that has been proven to suit your biology.
2. You overcome plateaus: If you're stuck in your weight loss journey, genetics can often provide the answer and show you which adjustment you need to make.
3. You're building confidence: Finally, you have a strategy based on facts about your own body. That's incredibly motivating and provides security.

By using your metabolism and genes as a guide, you lay the foundation for a diet that not only works in the short term, but leads you to your goals in the long term.

The most important dietary patterns put to the test

Low-carb, keto, paleo, or perhaps the Mediterranean diet? If you're wondering, "Which diet is right for me?", the sheer number of options can quickly become overwhelming. But don't worry, we'll shed some light on the subject.

This isn't about declaring one diet "the best." Rather, it's about understanding the fundamental principles, the potential benefits, and the realistic challenges of everyday life. This will allow you to make an informed decision about which approach is right for you.

Low-carb and ketogenic diet

The basic idea behind low-carb is quite straightforward: you significantly reduce carbohydrates. Sugar, bread, pasta, and often starchy vegetables are replaced by more protein and fat from meat, fish, eggs, nuts, and vegetables. The goal? To stabilize blood sugar levels and encourage the body to use fat as its primary energy source.

The ketogenic diet is essentially the hardcore version of low-carb. Here, you drastically reduce your carbohydrate intake (often below 30 grams per day ) so that your body enters a metabolic state called ketosis. Your liver then produces ketone bodies from fat, which serve as an alternative fuel for your brain and body.

• Potentially suitable for: People whose genetics favor very efficient fat metabolism – often referred to as a "fat type". A DNA test can provide clarity here. This approach may also be worth considering in cases of insulin resistance.
• Potential challenges: The initial phase can feel like a "keto flu" with fatigue and headaches. Strict adherence requires discipline, especially when eating out or visiting friends.

Paleo – The Stone Age Diet

The Paleo diet is based on what our ancestors likely ate during the Stone Age. The focus is clearly on unprocessed, natural foods. The menu includes meat, fish, eggs, plenty of vegetables, some fruit, nuts, and seeds.

What gets cut from the table? Grains, legumes, dairy products, and all processed sugars. The theory behind it: Our bodies are not genetically adapted to the modern, highly processed diet. Returning to "natural" foods is supposed to reduce inflammation and promote health.

Paleo is less of a simple calorie-counting diet and more of a lifestyle. The quality of food is crucial – think grass-fed meat or wild-caught fish.

The Mediterranean diet

The Mediterranean diet is less a strict diet than a time-tested lifestyle, inspired by the eating habits of countries like Greece and southern Italy. It is brimming with plant-based foods such as vegetables, fruits, whole grains, legumes, and nuts.

The main source of fat is high-quality olive oil. Fish and poultry are eaten in moderation, while red meat is consumed only rarely. This approach is particularly well-known and valued for its positive effects on cardiovascular health.

• Potentially suitable for: Virtually everyone. It's particularly well-suited for people seeking a balanced and, above all, sustainable approach. Individuals whose metabolism responds well to a moderate amount of complex carbohydrates ("balanced type") usually feel very comfortable with this diet.
• Potential challenges: There are no hard and fast rules, which can make implementation difficult for some. The focus on fresh, high-quality ingredients can also be somewhat more expensive.

Popular diets compared

To make your decision easier, we've summarized the key features of the most popular diets in a table. Here you can see at a glance which approach might suit which body type.

Diet type	Basic principle	Potentially suitable for	Potential challenges
Low-carb	Reduction of carbohydrates, more protein and fat.	For people who react quickly to carbohydrates; to stabilize blood sugar.	Social occasions, abstaining from bread and pasta, initial adjustment.
Ketogenic	Extreme reduction of carbohydrates (<30g), very high fat intake to achieve ketosis.	Genetic “fat types”, people with insulin resistance, for strong short-term results.	Very restrictive, requires precise planning, risk of nutrient deficiencies.
Paleo	Only unprocessed foods such as meat, fish, vegetables, and nuts. No grains, sugar, or dairy products.	For people with food intolerances, focus on nutrient density and natural foods.	More expensive, and giving up entire food groups can be time-consuming in everyday life.
Mediterranean	Lots of vegetables, fruit, olive oil, fish; little red meat. Balanced and plant-based.	Almost everyone, especially for long-term heart health and as a sustainable lifestyle.	Less strict rules require more personal responsibility and a focus on quality.

This overview is intended as a guide. Ultimately, what matters is what not only feels right to you, but can also be realistically implemented in everyday life.

The connection to your metabolic type

Now it gets really interesting: How does all this relate to your own personal biology? A DNA metabolism test can reveal whether your body is genetically predisposed to efficiently burn fats or carbohydrates.

Imagine the test reveals that you're a "fat type." Your body is excellent at using fat as an energy source. In that case, a ketogenic or low-carb diet might not only be effective for you, but would actually feel great. You'd probably feel full quickly and have plenty of energy.

If, on the other hand, you're a "carbohydrate type," an extremely high-fat diet like keto could leave you feeling tired and dissatisfied. A more balanced approach, such as the Mediterranean diet with complex carbohydrates from whole grains and legumes, would likely be a wiser choice. To deepen your knowledge, you'll find seven more examples of diets and how they work in our guide.

This overview is intended to serve as your compass. Instead of blindly following a trend, you can now consider which of these philosophies might best suit your goals, your preferences, and – if known – your metabolic profile.

How to put your new diet to the test in everyday life

The best theory and the most careful pre-selection are useless if they don't stand up to the practical test. Now that you've found a diet that might suit your goals and your body, the truly crucial part begins: the testing phase. This is where you'll find out if the chosen diet is really the right diet for you .

The path to achieving this can be divided into three phases: First, you define your profile, then you make a pre-selection, and finally comes the crucial testing phase, which we will now examine more closely.

At the end of this systematic path, you will no longer be guessing, but making informed decisions for your body.

Define a clear testing period.

Your body and mind need time to adjust to the new diet. Such a change doesn't happen overnight. Four to six weeks has proven to be an ideal trial period.

During this time, your body can adapt. The first few days can be tough – think "low-carb flu" or giving up sugar. That's normal. But after about one to two weeks, you should start to feel the first positive signs.

More than just the scales: the true indicators of success

Your weight is just one of many indicators, and often not even the most important one. A diet that makes you lighter but leaves you feeling lethargic and grumpy is not the solution. Instead, pay attention to a wider range of signals your body is sending you.

These metrics give you a much more honest picture:

• Your energy level: Do you feel more awake and stable during the day? Has the dreaded afternoon slump disappeared?
• Your sleep quality: Do you sleep more deeply and wake up feeling more refreshed? Or do you lie awake at night because you are hungry or restless?
• Your digestion: How is your stomach reacting? Do you feel less bloated? Your digestion is an excellent indicator of whether your body can process the new food well.
• Your mood and concentration: Are you mentally clearer and more balanced? Or do you feel irritable and have difficulty concentrating?
• Are you experiencing less frequent cravings ? That's a great sign that your blood sugar levels are more stable.

Consider this testing period as an experiment in which you curiously gather data about yourself. There is no "failure," only learning processes. You are the researcher, and your body is your subject of study.

The food diary – your most important tool

Your memory can play tricks on you, but a diary doesn't lie. Document what you eat for at least two weeks and – very importantly – how you feel while eating. It doesn't have to be complicated at all.

A simple notebook or an app is perfectly sufficient. Write down:

• What and when you eat: All meals and snacks.
• How you feel afterwards: energy level, digestion, mood (e.g. on a scale of 1-10).
• Key features: sleep quality, athletic performance, stress level.

You'll start noticing patterns after just a short time. You might find that a protein-rich breakfast gives you much more energy than a sugary smoothie. These insights are invaluable. To delve even deeper into the subject, it can be helpful to have your metabolism tested and compare your personal observations with concrete data.

Adapt instead of giving up: How to deal with initial difficulties.

It's perfectly normal for things not to go perfectly from the start. The key to success lies in remaining flexible and making small adjustments, instead of giving up at the first hurdle.

Here are some typical scenarios and possible solutions:

• Scenario 1: You constantly feel tired.

  • Possible cause: You might be eating too little or your nutrient intake might not be balanced. On a low-carb diet, you could be deficient in electrolytes like salt and magnesium.
  • Adjustments: Slightly increase the calorie intake by adding healthy fats (avocado, nuts) or protein. A salty bone broth can also help.

• Scenario 2: You have an uncontrollable craving for sweets.

  • Possible cause: Your body is still used to sugar or your meals don't fill you up enough.
  • Adjustments: Make sure each meal contains enough protein and fiber. A handful of berries can often wonderfully satisfy a sweet tooth.

• Scenario 3: The diet is too complicated for you in everyday life.

  • Possible cause: You chose recipes that were too complicated.
  • Adjustments: Simplify your meals! Focus on one protein source, a large portion of vegetables, and a healthy fat source. Meal prepping on weekends can also make your life easier.

This dynamic process of testing, observing, and adapting is what makes a dietary change truly sustainable. This is how you develop a deep understanding of your body's needs and become an expert in your own health.

The most frequently asked questions about choosing the right diet

Questions almost always arise on the journey to finding the ideal diet. And that's a good thing, because it shows you're seriously engaging with your body. We've compiled the most frequently asked questions for you here and provide clear, practical answers.

How long should I test a diet to know if it really works?

Your body isn't a machine that can simply be reprogrammed at the push of a button. It needs time to adjust to a new way of eating. Our experience shows that a trial period of four to six weeks is ideal for seeing meaningful results.

In the first week or two, you might struggle with adjustment effects like fatigue or cravings – that's perfectly normal. The important thing is not to give up immediately and, above all, not to focus solely on the number on the scale. The real indicators of success are your energy levels, the quality of your sleep, your digestion, and your overall well-being. If you see positive changes in these areas, you're on the right track.

Do I need to exercise for my dietary change to work?

Honestly, diet is by far the biggest factor when you want to change your weight. You can hardly compensate for a poor diet with exercise. But – and this is crucial – exercise is the perfect partner for changing your diet. It acts like a turbocharger.

Exercise boosts your metabolism, builds valuable muscle (which burns more calories even at rest), and improves your overall well-being as well as your body's response to insulin. Most importantly, though: find something you truly enjoy. Whether it's dancing, hiking, weight training, or cycling – what you stick with long-term beats any short-term struggle.

What if my DNA test says diet X is perfect, but I don't feel good about it?

An extremely important question, and the answer is quite simple: Always listen to your body! Your body doesn't lie. A DNA metabolic test, like the one from mybody® , provides you with a scientifically sound blueprint of your genetic predisposition. This is an incredibly valuable starting point.

But you are more than the sum of your genes. Your current lifestyle, your stress level, the state of your gut microbiome, and hormonal fluctuations play at least as important a role.

Your genetics are the map, but you're still in the driver's seat. If a road feels bumpy, you adjust your route instead of stubbornly continuing on.

This might mean making a few minor adjustments within your genetic recommendations. For example, someone with a "fat-protein type" might find that a slightly lower fat intake or certain vegetables suit them better than the strictest keto diet. The test will give you a general idea – you'll take care of the fine-tuning.

How do I deal with setbacks or a plateau in my weight?

A plateau is not a failure. It's a signal from your body that it has adapted to the new situation. This happens to almost everyone. Instead of throwing in the towel in frustration, use it as an opportunity to review your strategy.

These points usually help:

• Check your food diary: Have any small habits crept in unnoticed? Perhaps your portions have slowly become larger, or you snack more often than you thought.
• Vary your training: Your body is smart and gets used to routines. A new training stimulus can really kick-start your metabolism again.
• Pay attention to stress and sleep: Chronic stress and insufficient sleep can actually block fat burning due to the hormone cortisol. Sometimes an extra hour of sleep is more beneficial than an extra hour at the gym.
• Adjust your calorie intake: If you've already lost a few pounds, your body now needs less energy. A small adjustment to your calorie intake may be necessary to break through the plateau.

Setbacks are part of the process. What's important is not that you fall down, but that you simply get back up with what you've learned and keep going.
