Introduction

I've been active in the fitness field for over 12 years. For more than 10 years I've been part of the fitness industry, and for the last 5 years I've competed professionally in the Men's Physique category.

The more experience I gather, the clearer one thing becomes to me: many people make healthy eating and losing weight more complicated than it needs to be.

But it doesn't have to be that way.

Today there are so many forms of nutrition that you're already confused before you even start:

Keto
Low carb
Intermittent fasting
Low fat
Counting calories
Eating by the clock
Eating without a clock

Every approach claims to be the right one. But if you leave out the names, most of the concepts that work build on similar foundations: more real foods, enough protein, fewer heavily processed products, fewer liquid calories, more movement and more consistency.

That's why, in my view, most people don't need a new diet.

They need a system.

A system they understand. A system they can apply in everyday life. A system that doesn't rely on extremes but helps you make better decisions every day.

Why most diets don't work in real life

Let's start honestly.

Most diets can work for a certain period of time. If someone eats less, reduces calories and follows a plan strictly enough, they will almost certainly see a result.

But the more important question is: what happens afterwards?

This is exactly what's rarely talked about. Many people start a diet thinking: I'll do this for two months and then I'm done. But health, body shape and energy don't work like a short-term project. If you go back to your old habits after the plan ends, the old result also comes back step by step.

Sometimes even stronger than before.

I've seen this in many people. And I've experienced it myself too.

My first competition preparation was one of the strictest phases I've ever gone through. Everything was measured. Everything was planned. The goal was clear: stage, shape, result.

The result came. But the experience was hard. I'm not just talking about discipline. I'm talking about a plan that drains you mentally. Towards the end I could hardly wait for the competition to be over so that I could, it felt like, eat the whole world.

And that's exactly what happened.

After the competition I lost the shape I had built within about a month. Not just a little. It was practically gone. From all that eating I even had restless nights. I felt like someone who had been rescued from a desert island and was finally sitting in front of a table full of food.

Back then I understood something very important.

A plan can get you to a result. But if you can't live with that plan, it isn't a system. It's a temporary project. And temporary projects often only bring temporary results.

The problem isn't just willpower

Many people blame themselves:

"I'm not disciplined enough."
"I can't control myself."
"I always start and then stop again."
"I guess I'm not one of the people who can do it."

From my point of view this thinking is dangerous, because it shifts the focus.

Yes, personal responsibility is important. Yes, decisions are important. But we don't live in a neutral environment.

We live in a world where food is everywhere. In the supermarket, at the checkout, on our phones, in advertising, on social media, on children's packaging, in the office and at the petrol station. Many products are made to be tasty, cheap, convenient and easy to overeat.

We're not weak. We just live in an environment that constantly pushes us towards the easier decision.

If you don't have a system, you rely on mood. But mood changes. One day you're motivated. The next you're tired. One time you slept well. Another time you're stressed. One day you have time. The next you just eat whatever happens to be there.

A system helps you not to depend only on willpower.

How the body stores fat: the signal many don't understand

When it comes to losing weight, many people first think of calories.

"Today I'll only eat 1300 calories."
"I'll cut down to 1500 calories."
"This only has 100 calories, so it's okay."

Calories matter. No one gets around energy balance. But the body isn't a cash register. It doesn't simply count calories. It reacts to food.

On paper the calories can look similar. In the body, however, it isn't the same.

The whole fruit has structure. It contains fibre. It has volume. You have to chew it. It fills you up better and you usually eat it more slowly.

Juice is a different story. When you press it, you remove a large part of the structure and the fibre. What's left is a liquid you can drink in a few seconds. So the sugar from several fruits arrives much faster and fills you up considerably less.

A processed fruit bar can be even further removed. There the fruit is often already concentrate, paste, syrup or purée. On top of that come further ingredients. The product is shaped, sweetened, stabilised and packaged so that it's convenient, tasty and has a long shelf life.

All three can have similar calories. But they don't give the body the same signal.

One of the most important signals is called insulin.

Insulin is a hormone that helps the body use food. When blood sugar rises, the body releases insulin. Insulin helps to take sugar out of the blood and use it or store it.

Insulin isn't bad. Without insulin we can't live.

It becomes problematic when we let blood sugar spike sharply again and again throughout the day with quickly available foods and drinks. Then the body has to react constantly. If this repeats over years, appetite, weight and energy can become significantly harder to manage.

Can you eat thousands of calories and still starve?

That sounds impossible. But without insulin the body can't use food normally.

This is seen most clearly in type 1 diabetes.

In type 1 diabetes the body produces little or no insulin. A person can eat. They can take in calories. They can have a lot of sugar in the blood. But if there isn't enough insulin, the body can't use this food properly.

Before the discovery of insulin as a treatment, this was the reality for many people with type 1 diabetes. They lost weight dramatically and fell into a life-threatening condition, even though they were taking in food.

This example shows how important insulin is. Not because we should be afraid of it. But because we should understand its role.

The problem isn't that the body releases insulin. The problem is when we make it react strongly all day long, again and again:

sweet drinks
fruit juices
sweets
white baked goods
sweet snacks
constant snacking

Then the body too often gets the signal: fast food is here, process it.

That's why the question isn't only: "How many calories does this have?" More important is also:

What kind of food is it?
How heavily processed is it?
Does it contain fibre?
Does it contain protein?
Is it liquid or whole?
Are you eating it on an empty stomach?
What signal does it give the body?

The system: 5 principles for nutrition you can stick to

The goal of this system isn't to make you afraid of carbohydrates, sugar or insulin.

The goal is to make nutrition more stable, more understandable and easier to control in everyday life.

This isn't a diet. They are principles you can use in almost any eating style.

The five principles are:

Choose foods with less processing.
Build protein into every main meal.
Order your meal so that the body can react more calmly.
Watch out for hidden calories.
Move after eating.

1. Choose foods with less processing

Not every kind of processing is a problem.

When you cut a tomato, boil potatoes, prepare meat, freeze vegetables or ferment cabbage, that's also a form of processing. But it doesn't automatically turn the food into something completely different. In many cases it even makes food easier to eat, safer or more sensible.

The problem begins when a food goes through so many industrial steps that it hardly resembles the original product anymore.

Let's take a simple example: an orange.

A whole orange contains water, fibre, volume and structure. You have to chew it. It fills you up better. It's harder to eat too much of it.

If you press it into juice, you've already made a major change. You remove a large part of the fibre and the structure. What's left is a liquid you can drink in seconds. So the sugar from several fruits arrives faster and fills you up much less.

Now imagine a product that goes through even more steps:

a cheap raw material is refined
natural structure is lost
sugar, syrups, refined fats, starch, salt, flavourings, colourings or stabilisers are added
then the product is shaped, packaged and advertised so that it's convenient, has a long shelf life and is repeatedly purchasable

That's no longer simply food. That's a product.

And the goal of this product isn't to be maximally good for your body. The goal is to be cheap to produce, have a long shelf life, transport well, be so tasty that you buy it again, and be profitable for the company.

That doesn't mean you can never eat packaged foods. It only means you should understand the difference.

The fewer steps there are between nature and plate, the easier it usually is to recognise what really ends up in your body.

2. Build protein into every main meal

Protein isn't only important for people who train.

It's important for anyone who wants to stay full, have more stable energy and support the body better.

When you eat protein, the body has to do more work to digest and use it. Simply put: of the main nutrients, protein has the highest thermic effect. So the body uses comparatively more energy processing it.

That doesn't mean you can eat unlimited protein and magically lose weight. It only means that protein is a better ally than a meal that consists almost only of sugar and baked goods.

Protein also fills you up more. If your breakfast consists only of a croissant and a sweet coffee, you'll probably be looking for something to eat again after two hours. If your breakfast contains eggs, natural yoghurt, quark, fish, meat, cheese, legumes, nuts or another protein source, the chance is much greater that you'll stay full for longer.

Practical protein sources are:

Eggs
Natural yoghurt
Quark
Fish
Meat
Cheese
Legumes
Nuts in moderate amounts

That's why protein is included in every main meal in my system. Not because everyone has to eat like competitive athletes. But because the body works better when it gets a stable foundation.

3. Order your meal so that the body can react more calmly

Once we understand how blood sugar and insulin work, the order in which you eat makes much more sense.

The goal isn't to turn every meal into a complicated ritual. The goal is to reduce sharp spikes when it's possible.

A simple order is:

Fibre first: salad, vegetables, leafy greens, sauerkraut or vegetable soup.
Then protein and fat: meat, fish, eggs, seafood, cheese, natural yoghurt, legumes, olive oil, avocado or nuts.
Carbohydrates or sweets last: rice, potatoes, pasta, bread, fruit or dessert.

An example: you have salad, seafood and spaghetti. If you start straight away with the spaghetti, the carbohydrates come first and are absorbed faster. If you first eat salad and seafood and then the spaghetti, the body gets fibre and protein first. This can make the blood sugar response after the meal calmer.

Another example: you eat pizza. You don't have to tell yourself: never pizza again. Just eat a salad beforehand. That way you don't forbid the food but put it in a better context.

The same applies to dessert. Dessert after a main meal is often the better choice than sweets on an empty stomach. If fibre, protein and fat are there beforehand, sugar doesn't arrive alone and not quite so quickly.

With fruit the idea is similar. A whole fruit is better than juice, because it contains structure and fibre. But a very large portion of fruit on an empty stomach isn't always the best choice if your goal is stable energy and fewer cravings. It's often better to eat fruit after a meal or to combine it with natural yoghurt, quark, nuts or another source of protein and fat.

And apple cider vinegar?

For some people, a little vinegar before a carbohydrate-rich meal can contribute to a calmer blood sugar response. But vinegar isn't magic and doesn't replace a good system. Anyone with stomach problems, reflux, sensitivities or who takes medication should be careful.

The foundation stays the same: fibre, protein and fat before carbohydrates.

4. Watch out for hidden calories

Many people don't only eat too much through large meals.

The problem often lies in things we don't even count as real food.

Hidden calories frequently come from:

juices and freshly pressed juices
sugar in coffee
ready-made cappuccino drinks
latte drinks with syrup
ready-made sauces and dressings
mayonnaise
granola
protein bars
nuts in large amounts
sugar-free sweets that still have calories

Many people are also fooled by the label "sugar-free". Sugar-free doesn't automatically mean calorie-free. A whole packet of sugar-free biscuits can still contain fats, flours, sweeteners, nuts, chocolate substitutes and enough calories to change your whole day. The problem isn't that such products exist. The problem is that the label often makes us careless.

Coffee is a good example. Black coffee has almost no calories. But coffee with sugar, syrup, cream or a ready-made cappuccino from a can is a different story. Many packaged iced coffees, cappuccino drinks and coffee drinks contain a lot of sugar. You think you're drinking coffee. In reality you're drinking a dessert.

Sauces are another example. You can make yourself a good meal with meat, potatoes and salad. If you then add a lot of sauce, the whole meal changes. Not because sauce is forbidden. But because it unnoticed changes the total amount.

The simple rule is: don't only look at the main meal. Also look at what you add to it.

5. Move after eating

Not every solution has to be complicated.

After eating, blood sugar naturally rises, especially when the meal contains more carbohydrates. The body has to take this sugar out of the blood and use it.

Movement helps in a very simple way: the muscles start to work and use part of this glucose as energy.

I'm not talking about hard training. I'm not talking about cardio to exhaustion. I'm talking about 10 to 15 minutes of light movement after eating.

That can be:

a walk
climbing stairs
going outside briefly
light activity at home
simply not staying seated on the sofa or in front of the computer right away

This is especially useful after carbohydrate-rich meals. If you've eaten pasta, potatoes, rice, bread, pizza or dessert, a short walk afterwards can help to use part of the glucose more efficiently and reduce sharp blood sugar spikes.

The idea is to give the body a better context. Instead of eating and then staying completely motionless, you give the muscles a reason to use part of the energy.

Small habits seem insignificant until you repeat them long enough.

How to include your favourite foods without losing control

Healthy eating doesn't mean giving up everything that tastes good.

This is exactly where many people fail. They start a plan feeling that from Monday on their life ends: no sweets, no bread, no restaurants, no favourite dishes, no social life.

That rarely works long term.

It's much better to learn how to include favourite foods without them controlling the whole day.

In practice that means:

A dessert after a main meal is often better than sweets on an empty stomach.
Protein and vegetables before pasta are better than just pasta.
Coffee without sugar or with less sugar is better than a daily drink that's actually a dessert.
A whole fruit is better than juice.
80 percent stable decisions that you can keep are better than 100 percent perfection for two weeks.

If you understand how food works, you can allow yourself tasty things without losing direction.

What does this mean for parents?

This topic is especially important for parents.

Not because parents have to be perfect. No one is perfect. But because children develop their eating culture very early.

Children observe. They see:

what's visible at home
what gets bought
whether food just comes quickly out of a packet or is part of daily care
whether sweets are used as a reward for everything
whether vegetables are a punishment or a normal part of the plate

The truth is: eating culture is hardly really learned at school. Yet it should be. Because a person can have many problems until a health problem arises. Then suddenly only this one problem remains.

Health should be a priority.

First your own health. Then the health of the people closest to you. After that comes everything else.

When we talk about food for children from age 1, we have to be careful. Children have different needs than adults. Specific recommendations should always match age, development and state of health.

But there's a universal principle: environment shapes habits.

If a child grows up in an environment with more real foods, more variety, more vegetables, better products and less hidden sugar, that's an investment. Not just in a meal, but in culture.

This is where I see the point of projects like BioBabyKitchen. It isn't only about offering convenient food. It's about creating a better alternative in a world where convenient often isn't the best choice.

Many parents are busy. They work, they rush, they're tired. If we want better decisions, they not only have to be healthy but also realistic.

Freshly cooked organic meals for children, a well-thought-out weekly menu or a practical monthly subscription can help exactly there: in real everyday life. Not as a perfect solution for everything, but as a better foundation for families who want to make healthy nutrition for children easier.

Conclusion: don't start a new diet, build a system

A diet often has a beginning and an end. A system stays.

A diet often says: just hold on. A system says: understand what you're doing.

A diet often makes you wait for the day it's over. A system helps you live better now.

Healthy eating isn't a punishment. It isn't deprivation and it isn't a list of bans.

It's culture:

the culture of understanding your own body better
making better decisions
not letting yourself be controlled by everyday life and marketing
and caring for yourself and the people around you

The best part: you don't have to start perfectly. You only have to start understanding better.

Frequently asked questions

Do I have to avoid carbohydrates to lose weight?

No. Carbohydrates aren't the enemy. More important is which source they come from, how much of them you eat, whether fibre is included, what you combine them with and whether you eat them on an empty stomach or after a meal.

Why do diets often not work long term?

Many diets are time-limited and too restrictive. They can bring short-term results. But if you then return to your old habits, the result usually doesn't last.

Is freshly pressed juice really healthy?

Freshly pressed juice can contain vitamins, but it also provides sugar in liquid form. In most cases the whole fruit is the better choice, because it contains fibre, has to be chewed and fills you up more.

What is the simplest principle for healthy eating in everyday life?

Start with less heavily processed foods. Build protein into main meals. Order your meals better. Watch out for hidden calories. Move after eating.

Do I have to give up sweets completely?

No. It isn't about complete deprivation. It's better to learn when and how you include sweets. A dessert after a main meal is often the better choice than sweets on an empty stomach.

Are processed foods always unhealthy?

No. Cutting, cooking, freezing or fermenting are also forms of processing and can be completely normal or sensible. It usually becomes problematic with heavily industrially processed products with many additives, sugar, flavourings and long ingredient lists.

Does a walk after eating help?

Yes. Light movement after eating can help the muscles use glucose from the blood and make the blood sugar response calmer. It doesn't need hard training. Often 10 to 15 minutes of walking is enough as a practical everyday impulse.

Why is your own nutrition important for parents?

Children learn above all through their environment. They see what's available at home, what gets bought, how people talk about food and which habits repeat every day.

What does healthy nutrition for children from age 1 mean?

Healthy nutrition for children from age 1 doesn't mean perfection. It's about real foods, variety, age-appropriate meals, less hidden sugar and an environment in which good food becomes normal. For specific health questions, professional advice should always be sought.
