Determine your metabolism: Find out what your body really needs

Do you know that feeling of constantly fighting against your own body? You try diets, force yourself to exercise, but the results are either elusive or short-lived. Perhaps the solution doesn't lie in even more discipline, but in finally truly understanding your body. To determine your metabolism , you first need to know how it works. It's about so much more than just burning calories – it's the foundation of all your physical and mental energy.

Your metabolism: What it really is and how you can control it

Think of your metabolism as your body's operating system. It's the sum of all the biochemical processes that tirelessly take place in your cells to convert food into vital energy. Without this engine, you couldn't breathe, think, or move. The fascinating thing is that each of us has our own unique operating system, determined by our DNA.

This system runs 24/7, even while you sleep. To truly understand and positively influence your metabolism, we need to take a closer look at the two main components of your energy expenditure.

Basal metabolic rate and activity-related energy expenditure: The two engines of your energy

Your basal metabolic rate (BMR) is the amount of energy your body uses at complete rest. This is the energy required for basic life-sustaining functions:

  • Breathing and heartbeat
  • Maintaining your body temperature
  • Cell renewal and repair processes
  • Brain function

Your basal metabolic rate accounts for the lion's share of your daily energy expenditure, usually between 60 and 75 percent . It is influenced by factors such as age, sex, height, weight, and especially your muscle mass. The simple formula is: more muscle means a higher basal metabolic rate, because muscle tissue burns significantly more energy than fat tissue, even at rest.

In addition, there's the energy expenditure from physical activity . This includes every single calorie you burn through physical activity – from walking the dog to housework to a strenuous workout. Even the digestion of food, also known as diet-induced thermogenesis, counts towards this.

Why blanket diets are doomed to fail

Now it becomes clear why a "one-size-fits-all" diet rarely leads to success. Your personal metabolism is a complex interplay of genetics, hormones, and your lifestyle. Your genes determine, for example, how efficiently your body processes carbohydrates, fats, or proteins. Some people are naturally better "carbohydrate burners," while others use fats much more efficiently as an energy source.

Your metabolism is as unique as your fingerprint. General advice ignores the most important variable in the equation: you. Knowing your metabolism precisely is therefore not a luxury, but the foundation for any successful and sustainable health strategy.

Hormones like thyroid hormones, insulin, and the stress hormone cortisol are the directors of your metabolism. An imbalance, for example caused by chronic stress, can throw the entire system off balance and make losing weight a struggle. This is precisely where precise analysis methods come in. Instead of guessing, they decipher the unique workings of your body.

Would you like to delve even deeper into the basics? In our guide, we've explained the topic of metabolism in simple terms and give you further insights.

The first and crucial step is therefore not to blindly follow the next fad diet. Instead, determine your individual metabolism. Only with this knowledge can you develop a nutrition and lifestyle strategy that truly suits you, gives you energy, and brings you closer to your goals – all without frustrating trial and error.

A comparison of the most common methods for metabolic analysis

If you want to understand your metabolism, you're faced with an exciting range of options. These range from quick online calculators to precise DNA analyses. Each method has its merits, but to find the right one for your goals, it's worth taking a close look at the advantages and disadvantages.

Let's compare the most common methods. This will help you quickly determine what level of detail is truly useful for you and when it's worthwhile to delve deeper into the analysis.

Estimation formulas and online calculators as a first point of reference

The simplest way to get a rough idea of ​​your calorie consumption is through mathematical formulas. The most well-known is probably the Harris-Benedict formula , which estimates your basal metabolic rate based on gender, age, height, and weight. Almost all fitness apps and online calculators use such algorithms.

These calculators are a great starting point to get a first impression of your energy needs – quick, free, and immediately available. Their major drawback, however, is that they are impersonal. Individual factors such as your body composition (more muscle = higher energy expenditure), your hormonal status, or your genetic predisposition are completely ignored.

An online calculator is like a rough map. It shows you the general direction, but for precise route planning you need much more detailed information. Two people with identical basic data can have completely different metabolisms.

Bioelectrical impedance analysis (BIA) for more details

A more precise method is bioelectrical impedance analysis, or BIA for short. You're probably familiar with it from body fat scales or the gym. A weak, imperceptible electrical current is sent through your body. Because fat, water, and muscle conduct electricity differently, the device can draw conclusions about your body composition.

A BIA measurement provides you with specific values ​​for:

  • Body fat percentage
  • Muscle mass in kilograms
  • Body water percentage

This data is invaluable because it goes far beyond just body weight. It helps you understand whether you're actually losing fat, water, or even valuable muscle mass. But be aware: accuracy depends heavily on the device and the circumstances. Your fluid levels, your last meal, or a recent workout can significantly skew the results.

Indirect calorimetry: the precise snapshot

If you want to know the exact details, there's no way around indirect calorimetry. It's considered the gold standard for determining resting energy expenditure. This method, often offered in sports medicine centers or by specialized nutritionists, involves breathing through a special mask for a few minutes.

The device precisely measures the oxygen you inhale and the carbon dioxide you exhale. From the ratio of these two gases, your energy consumption at rest can be calculated down to the calorie. You'll learn how much energy your body burns when you're doing absolutely nothing.

However precise the measurement may be, it remains a snapshot in time. Factors such as stress or your current state of health can influence the result. Furthermore, it is more complex and expensive than simpler methods. If you're wondering what other examples of metabolic tests exist and their benefits , you'll find a detailed overview in our guide.

This infographic will help you decide which path is right for your goals – whether it's more energy or targeted weight loss.

The metabolic decision tree shows pathways to energy (muscle building) or weight loss (fat loss) based on a calorie deficit question.

The tree diagram makes it clear: The choice of method depends directly on your personal goal. Is it about building muscle and energy, or about targeted fat loss through a calorie deficit?

Comparison of methods for determining metabolic rate

To make your decision easier, we have summarized the different approaches in a table. Here you can see at a glance which method is best suited for whom.

method accuracy Cost scope
Online calculator Small amount For free A first rough guide to get a feel for calorie needs.
BIA measurement Medium Low to medium Body composition tracking (fat vs. muscle) in a fitness context.
Indirect calorimetry High High Precise determination of resting metabolic rate for performance diagnostics or medical purposes.
DNA analysis Very high Medium to high Root cause analysis and development of a lifelong, personalized strategy.

As you can see, every method has its place. For a quick estimate, computers are sufficient; BIA is excellent for training management; and for maximum precision, the path leads to the laboratory. However, for a truly sustainable and personalized strategy, looking at your genes is the crucial step.

DNA-based metabolic analyses: A look inside

The methods mentioned so far determine what and how much your body is currently burning. A DNA analysis goes a crucial step further: it explains why this is the case. It reveals your genetic predisposition – the fundamental programming that controls your metabolism.

The DNA-based metabolic analysis from mybody® is the most precise way to find your own personal nutrition strategy. Your DNA reveals how efficiently your body processes the three macronutrients – carbohydrates, fats, and proteins. You receive a kind of personal instruction manual for your body that remains unchanged throughout your life. Instead of guessing which diet might work, you get a scientifically sound roadmap that is precisely tailored to your genetic predisposition.

How your genetic metabolic type determines your diet

Have you ever wondered why your best friend can eat pasta and bread without any problems, while the mere thought of it makes you gain weight? Or why someone in your circle of friends has great success with a high-fat, ketogenic diet, while you just feel sluggish and lethargic? The answer doesn't lie in your willpower, but is deeply rooted in your genetic makeup.

Each of us has a unique genetic code that determines how our body reacts to different nutrients. This predisposition is the reason why there simply cannot be one perfect diet for everyone. While simple methods like a BIA measurement or calorie calculators only scratch the surface, a genetic analysis goes straight to the root of your metabolism.

The three major macronutrient types

Basically, we distinguish three fundamental metabolic types based on genetic markers. This classification is based on which macronutrient – ​​carbohydrates, fats, or proteins – your body can use most efficiently for energy production. Of course, no one is 100% one type or the other, but the genetic predisposition is usually very clear.

  • The Carbohydrate Type (Type C): Your body is a master at converting carbohydrates into quick energy. You feel energized and full after a meal with whole-grain bread, potatoes, or rice. A diet too high in fat, on the other hand, often makes you sluggish.

  • The Protein Type (P Type): You need a protein- and fat-rich diet to function optimally. A steak with vegetables gives you energy for hours, while a large portion of pasta makes you tired and triggers cravings. Your body preferentially draws its energy from protein and fats.

  • The mixed type (M-type): Your metabolism is flexible and thrives on a balanced mix of all three macronutrients. Extreme diets, whether low-carb or low-fat, are usually not the best choice for you, as your body needs variety.

This knowledge puts an end to the frustrating guesswork. It explains why you get cravings after certain meals or why you simply can't lose weight despite counting calories. It's about working in harmony with your genetics instead of constantly fighting against them.

Your genetic code as an instruction manual

A genetic metabolic analysis, like the one offered by mybody® , is far more than just determining your macronutrient type. It's a personal user manual for your body. Your DNA reveals how you react to certain foods, which sport is most effective for you, and which hidden levers you can use to improve your health.

Imagine not only finding out whether you should avoid carbohydrates or fats, but also:

  • Your sense of satiety: Is there a genetic predisposition that causes you to feel full less often and to reach for snacks more frequently?
  • Your predisposition to being overweight: How strongly does your genetics influence your tendency to gain weight (the so-called yo-yo effect)?
  • Your optimal sporting activity: Do you benefit more from endurance sports like jogging or from strength training to boost your metabolism and burn fat?

A genetic analysis doesn't provide short-term diet rules, but rather a lifelong strategy. The results don't change – they are a reliable foundation you can always refer back to, regardless of whether your goal is weight loss, muscle gain, or simply more energy in everyday life.

This field of science, which investigates the connection between genes and nutrition, is called nutrigenetics. If you'd like to delve deeper into this fascinating topic, you can read more about what nutrigenetics is and how it influences our lives on our science portal.

A practical example

Let's take Anna, for example. She's a clear carbohydrate type. For years, she tortured herself with low-carb diets because everyone raved about them. While she did lose weight in the short term, she constantly felt tired, irritable, and had an enormous craving for sweets. After a genetic analysis by mybody®, she discovered that her body needs complex carbohydrates to function optimally.

She's changing her diet: Instead of completely cutting out carbohydrates, she's now consciously incorporating oatmeal for breakfast, quinoa for lunch, and sweet potatoes in the evening. The result? Her cravings disappear, she has much more energy during the day, and she's losing weight sustainably. Simply because she's finally found a way of eating that suits her body and that she can stick to without deprivation.

Anna's example vividly illustrates that determining your metabolism means learning your body's unique language. A DNA analysis is the most precise and personal interpreter you can find.

From analysis results to everyday routine: how to implement your findings

Holding the results of your analysis in your hands is a great first step. But the true value of your new insights only unfolds when they move from the page to your everyday life. Now comes the most exciting part: implementation. Here you'll find practical guidance on how to transform the data from your metabolic analysis into sustainable, motivating habits.

Your result isn't a rigid set of rules, but your own personal roadmap. It shows you the most efficient path to your goals – whether that's more energy, weight loss, or simply a better sense of well-being. Instead of continuing to grope in the dark, you now have a clear compass. It helps you make the right decisions regarding nutrition, exercise, and lifestyle.

Your personal nutrition plan – step by step

Perhaps the most important insight from your analysis concerns the composition of your meals. It's not about rigidly counting calories, but about getting the right calories from the optimal sources for you.

1. Finding the right macronutrient distribution. A genetic analysis, in particular, gives you clear indications of your ideal ratio of carbohydrates, fats, and proteins.

  • Are you a carbohydrate type? Then focus on complex carbohydrates like whole grain products, oatmeal, quinoa, and legumes. They provide you with long-lasting energy and keep you feeling full.
  • Are you a protein person? Prioritize high-quality protein sources like lean meat, fish, eggs, and tofu. Combine them with healthy fats from avocados, nuts, and olive oil.
  • Are you a mixed type? Your strength lies in balance. Make sure that every meal contains a good mix of all three macronutrients.

2. Adjust portion sizes and meal frequency. Forget rigid rules like "three large meals a day." Your metabolic type also determines how best to distribute your food throughout the day. Some people benefit from smaller, more frequent meals to keep blood sugar levels stable, while others do better with three main meals.

Your results report is your personal blueprint. Start small: Put together a typical meal according to the new recommendations. Swap white bread for whole-grain bread, increase the amount of vegetables, or add a healthy fat source. Small, consistent changes are the key to success.

Movement that truly suits you

Not every sport has the same effect on every metabolism. Your genetic predisposition can tell you whether you benefit more from endurance training or from short, intense strength training sessions to optimally boost your metabolism.

  • Endurance types: Long, moderate sessions such as jogging, cycling or swimming are ideal to get fat burning going.
  • Strength training: Short, intense workouts like HIIT (High-Intensity Interval Training) or classic strength training build muscle mass. This sustainably increases your basal metabolic rate.

But honestly: The best plan is the one you actually stick to. Find an activity you enjoy and that fits easily into your daily routine. Even just 20-30 minutes of targeted exercise on most days of the week makes a huge difference.

The invisible helpers: sleep and stress management

You can eat and train perfectly – but if you're lacking sleep and stress, you'll sabotage your own efforts. Chronic stress leads to the release of cortisol, a hormone that promotes fat storage (especially around the abdomen) and slows down your metabolism.

At the same time, sufficient sleep is essential for hormonal regulation. Lack of sleep disrupts the hormones ghrelin and leptin, which are responsible for hunger and satiety, often leading to cravings. Try to sleep 7-8 hours per night and intentionally incorporate small moments of relaxation into your day.

The role of targeted nutrient supplementation

Sometimes your metabolism needs targeted support. Your analysis can also indicate an increased need for certain vitamins or minerals. A good example is vitamin D, a deficiency of which negatively affects the metabolism of over half of adults in Germany. According to the National Nutrition Survey II , 82 percent of men and 91 percent of women do not reach the recommended daily intake. Since vitamin D regulates calcium and phosphorus metabolism and influences insulin secretion, a deficiency can contribute to metabolic disorders.

Putting your results into practice is a process. There will be days when it's easier and others when it's more challenging. Be patient with yourself and celebrate the small victories. Every step brings you closer to a life full of energy and well-being. For detailed guidance, we've compiled a guide that shows you how to optimize your diet after receiving your test results .

Typical metabolic problems – and how to recognize them

You're watching your diet and exercising, but your weight is stagnating or even increasing? That's not only frustrating, but often a subtle warning signal from your body. Do you often feel tired, lethargic, or struggle with cravings, even though you're actually eating enough?

If you're nodding along, you're not alone. Symptoms like these often point to deeper imbalances. Most of the time, the problem isn't a lack of discipline or willpower, but rather underlying biochemical processes. Understanding these signals is the first step to regaining control and getting your metabolism back on track.

Insulin resistance: The silent saboteur in the background

One of the most common and insidious metabolic problems is insulin resistance . Imagine insulin as a key that unlocks the door for cells, allowing them to absorb sugar (glucose) from the blood for energy. With insulin resistance, however, the cells become, in a sense, "deaf" to this signal. The key no longer fits the lock properly.

Your body reacts by having the pancreas produce more and more insulin in an attempt to open the cells. This persistently high insulin level has massive consequences for your body:

  • Fat burning is blocked: As long as there is a lot of insulin in the blood, it signals the body to "store, not burn". Fat loss is then virtually impossible.
  • Constant cravings for sweets: Although there's enough sugar in your blood, it's not reaching your cells. Your brain is screaming for quick energy – and that usually comes from sugar and simple carbohydrates.
  • Fatigue immediately after eating: You eat, but the energy doesn't reach where it's needed. The result is the classic "food coma" or afternoon slump.

Insulin resistance develops gradually, often over years, and is the direct precursor to type 2 diabetes. It is a clear sign that your sugar metabolism is overloaded – usually due to a diet with too many processed carbohydrates and too little exercise.

Obesity: A vicious cycle for metabolism

For a long time, fat tissue was thought to be merely a passive energy store. Today we know: It is a highly active hormonal organ that constantly produces pro-inflammatory messenger substances. Therefore, being overweight is far more than a cosmetic problem – it is an active disruptive factor for your metabolism.

This creates a dangerous cycle: More body fat leads to more low-grade inflammation and increases insulin resistance. This, in turn, makes it even harder to lose fat and promotes further weight gain. The body enters a downward spiral from which it is difficult to escape.

A disrupted metabolism is rarely just a single issue. It's usually a domino effect, where one imbalance triggers another. The good news is: you can break this cycle by addressing the problem at its source – your individual metabolism.

The figures speak for themselves: The obesity rate in Germany has almost doubled since the turn of the millennium. While around 12.2 percent of adults suffered from obesity in 2003, this figure had risen to 19.7 percent by 2023. This is alarming, as excess weight slows down the basal metabolic rate and promotes metabolic syndrome. You can find more information in the current statistics on obesity at marcusknispel.com .

Hormonal imbalances as a hidden cause

Sometimes the root of the problem isn't directly related to diet or exercise, but to hormones. A key culprit is the thyroid gland. It's essentially the accelerator of your metabolism. An underactive thyroid (hypothyroidism) significantly reduces your basal metabolic rate. The consequences are often fatigue, constant feeling cold, and unexplained weight gain.

Chronic stress is also a real metabolism killer. If you're constantly under pressure, your body continuously releases the stress hormone cortisol. High cortisol levels specifically promote the storage of abdominal fat and disrupt your blood sugar levels. Analyzing your metabolism therefore also means understanding these deeper connections. Only then can you correctly interpret warning signs before they develop into serious problems.

Your questions about metabolic analysis

Okay, after all that information, you probably still have a few questions. That's perfectly understandable, as metabolism is a complex topic. We've compiled the most frequently asked questions we encounter in our practice to clear up any remaining uncertainties.

How quickly will I see results if I change my diet?

That's probably the question on everyone's mind. The honest answer: It's completely individual. Some people experience a real energy boost after just a few weeks and see initial results on the scale. That's the point at which your body realizes it's finally getting the right "fuel".

For truly lasting changes, especially when it comes to weight loss or muscle gain, you should give yourself two to three months . During this phase, new routines become ingrained, and your metabolism permanently adjusts to the optimized nutrient supply. Patience and perseverance are your best friends here.

Is it possible to permanently repair a "broken" metabolism?

The term "repair" might not be entirely appropriate. Your metabolism isn't a machine that breaks down, but rather an extremely adaptable system that reacts to everything you do. So you can't simply repair it, but you can permanently optimize it and steer it in the right direction .

With the right diet, targeted exercise, and a healthy lifestyle, you create the perfect conditions for your metabolism. A metabolic analysis acts like your personal compass: it shows you where your biggest levers lie, so you can keep your metabolism at a top level in the long term.

Does a metabolic analysis make sense even without being overweight?

Absolutely! Knowing your metabolism is so much more than just a weight-loss tool. Many of our clients use an analysis to achieve completely different goals:

  • More energy in everyday life: Find out which nutrients really give you the power to banish the classic afternoon slump once and for all.
  • Improved athletic performance: Optimize your diet for faster muscle growth and more effective recovery after training.
  • Fewer digestive problems: Finally understand which foods your body can easily utilize and which ones only put unnecessary strain on it.
  • Preventing illness: By giving your body what it truly needs, you strengthen your health in the long term and can actively counteract metabolic diseases such as insulin resistance.

Ultimately, it's about working with your body, not against it.

A metabolic analysis is an investment in yourself. You stop guessing and start acting based on facts about your unique body. This knowledge empowers you to make decisions every day that make you healthier, fitter, and more energetic.

What is the difference between a blood test and a DNA test?

Both offer incredibly valuable, but completely different insights. Think of it like this:

A blood test is a snapshot in time. It shows you your current health status. What are your thyroid hormone levels? Do you have enough iron? Is your blood sugar level stable? It's perfect for detecting acute deficiencies or hormonal imbalances.

A DNA metabolic analysis goes much deeper. It's your personal, unchanging "user manual." It reveals how your body naturally processes fats, carbohydrates, and proteins. This genetic predisposition forms the lifelong foundation for your nutritional strategy and perfectly complements the snapshot provided by a blood test.
