Losing weight through nutrition: Your journey to a weight you feel good at starts on your plate
ca. 21 Minuten
If you want to lose weight sustainably, your diet is the key. It’s about creating a small calorie deficit through smart food choices without missing out on important nutrients. Quality clearly beats quantity - because that’s the only way to optimally nourish your body and keep your metabolism going.
Why your diet is the key to success
Does this sound familiar? You push yourself for hours at the gym, but the number on the scale just won’t budge. The answer is often closer than you think: on your plate. Exercise is undoubtedly an important part of a healthy lifestyle, but nutrition plays the leading role in weight loss. There’s a reason they say: “Abs are made in the kitchen.”
One very simple principle determines success or failure: energy balance. To lose body fat, you need to burn more energy than you take in through food. Exercise can certainly help increase your energy expenditure, but its effect is often overestimated. Half an hour of jogging might burn 300 calories - which you can take right back in with a small chocolate bar or a latte.
The power is on your plate
Losing weight through nutrition isn’t about forbidding yourself from eating everything you enjoy or starting one extreme diet after another. It’s about developing a smart and, above all, sustainable way of eating that really suits you and your life. The benefits are enormous:
- Greater satiety: Foods rich in protein, fiber, and healthy fats keep you feeling full for much longer. Cravings? Say goodbye!
- Stable blood sugar: The right carbohydrates, such as those from whole grains, prevent the dreaded blood sugar spikes that make you tired and quickly make you hungry again.
- Optimal nutrient intake: You give your body all the vitamins and minerals it needs to keep your metabolism running and help you feel good all around.
Unfortunately, reality often looks different. The TK Nutrition Study “Eat What, Germany!” shows that only around 59 percent of people in Germany eat fresh fruit and vegetables every day. Among those under 40, the figure is just 49 percent. But the recommendation is clear: at least five portions a day to keep your body fit and prevent excess weight. If you’d like to learn more, you’ll find all the details in the full 2023 TK Nutrition Study.
The right mindset is everything
Your journey to your desired weight begins in your mind. Changing your diet isn’t a sprint; it’s a marathon. It’s about building new, healthy habits and developing a relaxed relationship with food.
Losing weight through diet isn’t about deprivation; it’s about self-care. You consciously give your body what it really needs to be strong, healthy, and full of energy.
When you focus on the quality of your food, you naturally learn to understand your body’s signals better. We’re all unique and respond differently to certain foods. That’s where personalized approaches come in, like the modern analyses offered by mybody-x.com. Instead of following rigid plans, you discover what your metabolism really needs. This personalized approach not only helps you reach your goal faster, but also boosts your self-confidence and motivation to stick with it long term.
The calorie deficit: your key to weight loss success
If you’re looking into losing weight through diet, there’s one term you can’t avoid: calorie deficit. But what does it really mean? It’s quite simple: You consume less energy (that is, fewer calories) than your body uses throughout the day. To make up the difference, your body has to draw on its own energy reserves—primarily stored body fat.
This is exactly what makes the pounds drop off. A healthy and, above all, sustainable deficit is usually between 300 and 500 calories a day. That’s enough to see noticeable results (around 0.5 kg per week), while remaining moderate enough to prevent nasty hunger pangs or nutrient deficiencies. An overly extreme deficit would only put your body into alarm mode, slow down your metabolism, and almost guarantee the infamous yo-yo effect.
The infographic below perfectly sums up the interplay between nutrition, mental strength, and energy.
It’s clear: A nutrient-rich diet is the foundation. It helps you maintain a positive mindset and gives you the energy you need for the journey—all crucial factors in reaching your goal.
How to find your personal calorie deficit
Everyone is different. Your individual calorie needs depend on many factors - age, sex, height, weight and, especially, your daily activity level. So there's no one-size-fits-all calorie recommendation. The first step is to estimate your approximate total energy expenditure.
- Basal metabolic rate: This is the amount of energy your body uses when completely at rest. In other words, just for vital functions such as breathing, heartbeat and metabolism.
- Activity energy expenditure: This energy is on top of that and includes everything you burn through movement - from walking the dog to a sweat-inducing workout at the gym.
Online calculators can give you a rough initial estimate. Then subtract the recommended 300 to 500 calories from that figure. Voilà, that's your daily calorie target.
Quality beats quantity - every time!
Trying to create a calorie deficit by simply eating half as much is the worst way to go about it. Think about it: 500 calories from a bag of chips affect your body very differently than 500 calories from a meal of grilled chicken breast, quinoa and a big serving of vegetables.
The real secret is to choose foods that provide plenty of nutrients for relatively few calories and, above all, keep you full for a long time. That way, you won't be constantly fighting hunger while still giving your body everything it needs for an active metabolism.
Focus on nutrient-dense foods. These include:
- Protein: Lean meat, fish, legumes and low-fat quark. They keep you feeling full and protect your valuable muscle mass from breaking down.
- Fiber: Plenty of vegetables, fruit and whole grains. They fill you up, keep your blood sugar stable and help prevent cravings.
- Healthy fats: Avocados, nuts and high-quality vegetable oils. They're essential for hormone balance and the absorption of fat-soluble vitamins.
You'll quickly notice that when you improve the quality of your diet, you often naturally eat fewer calories without feeling like you have to give anything up. This approach not only helps you lose weight, but also lays the foundation for a healthy lifestyle that lasts. A well-functioning metabolism is, of course, essential.

Your Nutrition Toolkit for Macro- and Micronutrients
A calorie deficit is the foundation, but the real art of losing weight lies in the composition of your meals. Think of your diet like a set of building blocks: to build something sturdy and full of energy, you need the right pieces in the right amounts. When losing weight through diet, those are the macro- and micronutrients.
It’s about much more than just cutting calories. The focus needs to be on giving your body exactly what it needs for its demanding tasks - from maintaining muscle to producing hormones to providing energy for everyday life. That’s the only way to avoid cravings, stay energized, and prevent your metabolism from slowing down.
The Three Pillars of Your Diet: Macronutrients
Macronutrients are your body’s main sources of energy. There are three groups: protein, carbohydrates, and fats. Each group has unique and essential functions, especially if you want to lose weight in a healthy, sustainable way. The right balance is the key to success.
The following table gives you a quick overview of why each of these building blocks is so important and where to find it.
| Macronutrient | Role in weight loss | Good sources |
|---|---|---|
| Protein | Keep you full for a long time, protect muscle mass from breaking down, and boost metabolism through their thermic effect. | Lean meat (chicken, turkey), fish, eggs, low-fat quark, skyr, legumes (lentils, chickpeas), tofu |
| Carbohydrates | As the body’s preferred energy source, they fuel the brain and muscles. Complex, fiber-rich options help keep blood sugar stable. | Whole grains (oats, quinoa), potatoes and sweet potatoes, vegetables, legumes, fruit |
| Fats (healthy) | Are essential for hormone production and the absorption of fat-soluble vitamins (A, D, E, K). They have anti-inflammatory effects. | Avocado, nuts & seeds (walnuts, flaxseeds), olive oil, canola oil, fatty fish (salmon, mackerel) |
As you can see, every macronutrient plays a crucial role. It’s not about completely eliminating any of them, but about intelligently combining the right sources.
Protein - Your Best Friend in a Calorie Deficit
Absolutely: Protein is your most important ally when losing weight. Why? It has the greatest satiating effect of all macronutrients. A protein-rich meal simply keeps you full much longer.
Your body also uses more energy to digest protein—this is called the thermic effect of food (TEF). But the most important point is protecting your muscles. In a calorie deficit, the body tends to break down muscle as well as fat. A high protein intake counteracts this and helps preserve your valuable, calorie-burning muscle mass.
Carbohydrates – The Smart Energy Providers
Carbohydrates have an undeserved bad reputation. Your brain and muscles love them as a source of energy. The trick is to choose the right ones. Forget simple carbohydrates from white flour and sugar, which send your blood sugar levels on a roller coaster ride and trigger cravings.
Instead, choose complex, fiber-rich carbohydrates. They’re digested slowly, provide long-lasting energy, and keep your blood sugar levels stable. Plus, fiber is great for digestion and helps you feel full.
Healthy Fats – Essential for Your Hormones
Fat doesn’t automatically make you fat—quite the opposite. Healthy fats are essential for life. They’re crucial for absorbing vitamins A, D, E, and K and play a central role in hormone production, which in turn regulates your metabolism and appetite. Simply focus on unsaturated fats from sources such as avocados, nuts, olive oil, and fatty fish.
Micronutrients: The Unsung Heroes
Alongside the major building blocks, there are micronutrients—vitamins, minerals, and trace elements. They don’t provide energy, but they’re absolutely essential for thousands of metabolic processes. A deficiency can sabotage your progress without you even realizing it.
Think of your metabolism as a Swiss watch. Micronutrients are the fine oil that ensures all the gears mesh smoothly. Even a single missing drop can bring the whole machine to a standstill.
Especially when you’re in a calorie deficit and eating less overall, the risk of a deficiency increases. Symptoms such as constant fatigue, difficulty concentrating, or a weak immune system can be early warning signs. For example, iron deficiency can lead to exhaustion, while a lack of magnesium can contribute to muscle cramps.
A colorful, varied diet with plenty of vegetables and fruit is the best insurance against deficiencies like these. If you want to dive deeper into the world of nutrients, our guide explains in detail exactly what a nutrient is and why getting enough is so important.
Ultimately, it’s about finding a smart balance. Choose whole, nutrient-rich foods. Every meal is a new opportunity to nourish your body properly and support it as much as possible on the way to your goal.
Find out what your body really needs
Standard diets have one major flaw: they ignore the most important factor of all - you. Each of us has a unique metabolism, shaped by our genes, our lifestyle, and even the tiny bacteria in our gut. So the key to sustainable weight loss through nutrition isn't blindly following a generic plan, but tuning in to your body's own signals.
Modern analyses help you decode exactly these signals. They're your tool for moving from guessing to knowing, and giving your body exactly what it needs to function optimally. That way, losing weight finally becomes effective and frustration-free.
Why your metabolism works differently
Have you ever wondered why your friend can eat pasta without a problem, while it seems to go straight to your hips? The answer could be hidden in your DNA. A DNA metabolism test gives you insight into how your body naturally processes fats, carbohydrates, and proteins.
These insights are pure gold. Imagine finding out that you're a metabolic type who converts fat into energy particularly efficiently. In that case, healthy fats from avocados, nuts, or olive oil may be a much better energy source for you than a large serving of pasta.
It's not about demonizing entire nutrient groups. It's about finding the optimal balance for you, based on your unique biological makeup.
This personalized approach takes the frustration out of losing weight. Instead of generic rules, you use targeted, effective strategies. If you're curious about how it works and what insights you can gain, you'll find all the details about a comprehensive metabolic analysis in our guide.
The hidden power of your gut
Another often overlooked factor in weight management is your microbiome - the community of trillions of bacteria in your gut. These little helpers have a huge influence on how you digest food, how many calories you absorb, and even what you crave.
When the gut flora is out of balance, it can lead to low-grade inflammation, which in turn disrupts your metabolism and can make losing weight a real struggle. A microbiome analysis shows you the state of your gut health and provides practical tips for improving it. Often, even small adjustments can make a huge difference:
- More fiber: Certain gut bacteria love the fiber in vegetables, legumes, and whole grains. They turn it into short-chain fatty acids, which reduce inflammation and promote a feeling of fullness.
- Probiotic foods: Yogurt, kefir, or sauerkraut provide beneficial bacteria that can help restore balance in your gut.
- Variety on your plate: The more colorful and varied your diet, the more diverse and resilient your microbiome will be.
By giving your gut targeted support, you can build a stable foundation for a healthy metabolism and lasting weight-loss success.
Nutrient deficiencies as an invisible brake
Sometimes, tiny micronutrients are missing and quietly slowing your progress. An iron deficiency can lead to fatigue and low energy - making exercise a real struggle. A lack of vitamin D or magnesium can cause important metabolic processes to slow down.
A high nutrient density is especially important when you're in a calorie deficit and eating less overall. A nutrient and mineral check can reveal hidden deficiencies like these. You can then take targeted steps to address them by adding the right foods to your plan or, after consulting an expert, taking appropriate supplements.
By the way, this desire to eat more consciously is no longer a niche concern. The 2024 Nutrition Report shows that 72 percent of people in Germany want to eat more healthily - compared to just 54 percent in 2018. This shows how awareness is growing that targeted nutrition is the key to greater well-being. Learn more about current nutrition trends in Germany in the full BMEL report.
By keeping these three pillars - genetics, gut health, and nutrient intake - in mind, you can take your nutrition to a whole new level. You leave the well-worn path of one-size-fits-all diets and develop a strategy that truly suits you - based on scientific facts about your own body.
Your nutrition plan for the perfect start
Enough theory! You now understand what matters for a calorie deficit and nutrients. Now let's put it into practice, and I'll show you how simple and delicious losing weight through nutrition can really be.
Think of this section as a flexible guide. The suggestions here aren’t strict rules, but a source of inspiration that you can easily adapt to your taste, preferences, and daily routine.
A flexible weekly plan for inspiration
A good plan gives you a clear structure without boxing you in. Here’s an example of what a week could look like—nutrient-rich, filling for longer, and perfect for supporting your calorie deficit.
- Breakfast (approx. 350-450 kcal): Focus on a good serving of protein and complex carbohydrates. This gives you energy for the day and helps prevent mid-morning cravings.
- Lunch (approx. 400-500 kcal): A colorful mix of lean protein, plenty of vegetables, and a small serving of fiber-rich foods is ideal. This helps you stay productive in the afternoon without falling into the typical post-lunch slump.
- Dinner (approx. 400-500 kcal): Lighter meals focused on protein and vegetables are often the best choice in the evening. This lets your body focus on recovery instead of laboring over heavy digestion.
Here are a few simple recipe ideas you can try right away:
| Meal | Recipe idea | Why it works |
|---|---|---|
| Breakfast | Skyr or low-fat quark with berries, a spoonful of flaxseed, and a handful of nuts. | Protein power: Skyr and quark are very filling. Berries provide vitamins, and nuts provide healthy fats. |
| Lunch | Large mixed salad with grilled chicken breast strips, chickpeas, and a light yogurt dressing. | Nutrient powerhouse: The vegetables provide fiber and micronutrients, while the chicken and chickpeas help keep you full. |
| Dinner | Oven-baked salmon fillet with steamed broccoli and a small spoonful of olive oil. | Light & healthy: Salmon is rich in omega-3 fatty acids, broccoli provides important nutrients, and the meal is easy to digest. |
The game changer: meal prep
One of the biggest obstacles to losing weight? Lack of time. After a long workday, most of us find it hard to cook an elaborate meal from scratch. That’s where meal prep comes in—the art of preparing meals ahead of time.
Just set aside an hour or two on Sunday to cook a few components for the coming week. This not only saves a lot of time and stress, but also helps you avoid unhealthy impulse buys when hunger strikes.
Simple meal prep tips to get started:
- Cook grains: Cook a larger batch of quinoa, rice, or millet ahead of time. That way, you’ll always have a healthy source of carbohydrates on hand.
- Chop vegetables: Wash and cut vegetables such as bell peppers, cucumbers, and carrots, and store them in airtight containers. Perfect for salads or a quick snack.
- Prepare protein: Cook a batch of lentils, pan-fry chicken breast, or hard-boil eggs. You can then easily add them to your meals.
Meal prep puts you in control. You consciously decide what to eat and no longer let sudden hunger lead you to make poor choices.
The smart shopping list for your success
A successful meal plan starts at the supermarket. My tip: Never shop when you’re hungry, and stick to your list. This protects you from impulse buys and ensures you always have the right ingredients at home.
Your basic shopping list could look like this:
- Protein sources: Eggs, low-fat quark, skyr, legumes (lentils, beans, chickpeas), tofu, lean meat or fish.
- Complex carbohydrates: Oats, quinoa, whole-wheat pasta, potatoes and sweet potatoes.
- Healthy fats: Avocado, nuts (walnuts, almonds), seeds (flax, chia), olive oil.
- Vegetables & fruit: Choose seasonal and colorful options! Broccoli, spinach, bell peppers, berries, apples.
- For flavor: Fresh herbs, onions, garlic, unsweetened spices.

Healthy snacks for when you’re a little hungry
Snacks are absolutely not off-limits—they just need to be chosen wisely. Instead of reaching for a bag of chips, always keep a healthy alternative within reach. This stabilizes your blood sugar and prevents cravings.
Ideas for smart snacks:
- A handful of unsalted nuts.
- An apple with a spoonful of nut butter.
- Vegetable sticks (carrots, cucumbers) with herbed quark.
- A small bowl of Greek yogurt.
- A hard-boiled egg.
This practical approach will help you put theory into practice and see your first results. Remember: Every meal is a new opportunity to do something good for your body and get one step closer to your goal.
Overcome common obstacles and stay motivated
Every path has its stumbling blocks—and the journey to your feel-good weight is no exception. That’s completely normal. Sometimes the number on the scale stops changing, sometimes a dinner invitation comes along, or your motivation suddenly wanes. It’s all part of the process.
What matters is not desperately avoiding these moments, but learning to handle them with confidence. With the right strategies in mind, you’ll get through difficult periods without throwing in the towel. See setbacks for what they are: part of the process and an opportunity to learn.
When the scale won’t budge: How to break through a plateau
You’re sticking to your plan, but the number on the scale hasn’t budged for days or weeks? Congratulations, you’ve hit a weight-loss plateau. There’s no need to panic; on the contrary, it’s a sign that your body has already adapted to the new situation.
Your body, now lighter, simply uses a little less energy than it did at the start. This is the time for a small course correction, not frustration.
- Take an honest look at your portions: Often, portions gradually get a little bigger again without you noticing. Take a few days to track what you eat briefly and honestly - it can work wonders.
- Introduce new training challenges: If you exercise, give your body a new challenge. Try a completely different sport or turn up the intensity of your usual workouts a little.
- Keep an eye on sleep and stress: Too little sleep and too much stress can raise cortisol levels and slow fat burning. So make sure you get enough rest.
Hidden calorie traps and social hurdles
Everyday life is full of little traps that can sabotage your calorie deficit without you noticing. The spoonful of sugar in your morning coffee, the supposedly “healthy” store-bought dressing on your salad, or one handful of nuts too many - it all adds up. The most important thing here is awareness.
Dinner invitations from friends or meals at a restaurant are another classic challenge. But here, too, you don’t have to give everything up.
You don’t have to say no to the invitation; just say a savvy yes to the right dishes. Choose grilled instead of fried food, ask for the sauce on the side, and opt for a side salad instead of fries.
The concern that healthy eating is an expensive luxury also holds many people back. But that’s not true. It’s absolutely possible to live well on a tight budget and still eat mindfully. The trick is to shop seasonally, look out for deals and, above all, cook for yourself.
Avoid the yo-yo effect once and for all
The infamous yo-yo effect is almost always the price you pay for overly radical diets. If you starve your body, it switches into emergency mode: it breaks down valuable muscle mass and slows your metabolism. Then, as soon as you start eating "normally" again, it stores every available calorie for fear of the next famine. The result: you quickly weigh more than before.
The key to preventing this? A moderate calorie deficit and a high-protein diet that protects your muscles. Losing weight sustainably through nutrition means establishing new, healthy habits that you can maintain for a lifetime - rather than putting yourself through a short-term crash diet.
Deep-rooted eating habits are often the biggest hurdle. Studies on food consumption in Germany show that despite increased awareness, high meat and sugar consumption is still the norm. Effective weight loss therefore often requires consciously reducing these exact food groups, as a WWF study highlights. You can find all the details about Germans' eating habits in the WWF study on food consumption.
Motivation is what gets you started. Habit is what keeps you going.
Motivation is a feeling - and feelings come and go. So don't rely on it alone. Instead, build strong, positive habits. Sunday meal prep, a set time for your walk, or a glass of water before every meal: routines like these will carry you through even the days when your motivation is at rock bottom.
Be kind to yourself. If one day goes completely off the rails, it's not the end of the world. Put it behind you and simply start fresh the next morning. Every single day is a new chance to get one step closer to your goal. Patience and self-compassion are your strongest tools for long-term success.
You now have all the tools you need to reach your goal. But the truly crucial step is moving from general knowledge to a personal strategy. Your body is unique - so why shouldn't your nutrition plan be too?
