3 pillars of nutrition

Let me paint a picture that might feel familiar. You enjoy being active, try to eat healthy, and prioritize sleep. You listen to podcasts, watch videos, and follow people on social media in an effort to constantly improve what you’re doing.

But your efforts aren’t gaining traction. You might even feel worse—afternoon energy crashes, declining focus. So what do you do?

Eat more protein? Optimize blood sugar or your microbiome? Or do you just need more discipline because you still slip up with your diet and consistency?

You’re doing more than 90% of people, yet you feel mentally and physically drained.

This is the health trap—doing lots of “healthy” things with little effect. It’s not that they don’t matter, but they’re not the most essential.

Let me start with a story you might relate to. Michal came to me a few years ago. He had lost weight through discipline, dietary changes, and exercise. But now he was tired and stuck. He wanted to move forward. After eating, he felt heavy and bloated, which drained his energy and interfered with training.

He didn’t want to lose more weight—he wanted to enjoy life fully: kids, work, running, hockey, gardening…

On paper, he was doing everything right. Sleeping early, eating lots of vegetables and protein, exercising daily.

But he was stuck in survival mode.

And that’s the problem. It wasn’t his fault. Most people start searching online for how to eat and train healthy because they want to lose weight and be healthy. But there’s no warning that what works temporarily for weight loss isn’t designed for a performance lifestyle.

The fitness world convinced us that the pinnacle of healthy eating is high protein, organic food, and magnesium supplements.

That creates a trap. Fitness influencers make content for weight loss, parroting popular advice without deeper understanding. People think that if they feel low on energy, they need supplements, have hormonal imbalances, or lack discipline when they indulge.

Meanwhile, others eat juice and croissants for breakfast, five protein bars for lunch, 120g of sugar during training, and beans with rice and veggies for dinner—and they enjoy excellent health and performance.

What’s the difference?

Some follow trends. Others understand nutrition principles and give their body what it needs, when it needs it.

I’m not saying food quality doesn’t matter—it does. But focusing only on quality is insufficient.

Here are the three pillars of nutrition you need to understand to optimize your physique, physical and mental health, and performance:

• Quality
• Quantity
• Timing

Quality

Modern diets are energy-rich but poor in vitamins and minerals. If you want to perform, you need premium fuel. Vitamins and minerals are essential for all bodily processes.

Magnesium is involved in over 300 enzyme systems. Without enough, many vital processes simply can’t happen.

Iron is crucial for oxygen transport, metabolism, DNA synthesis, and immune function. Iron deficiency is the most common nutritional deficiency. Magnesium isn’t far behind.

We also need fiber for digestion, blood sugar regulation, and microbiome health. You’ll find it in whole grains, vegetables, fruits, and legumes—yet fewer than 20% of people consume enough.

But this leads us to the second pillar.

Quantity

If you want to perform, you need premium fuel—but you won’t get far with a half-empty tank.

Here’s what I’ve learned in theory and practice: total energy intake is essential for health and performance.

Most health issues you hear about stem from excess weight—not because you had a croissant instead of eggs with avocado toast and kimchi.

Healthy eating isn’t just about maximizing vitamins and minerals in every meal. Total energy intake matters.

I’ve seen athletes with anemia that couldn’t be corrected—even with supplements. The issue wasn’t just iron intake. It was chronic energy deficiency. Her body couldn’t absorb iron effectively.

It’s like the chicken-or-egg dilemma. The body needs energy to absorb iron, which helps produce energy.

Without enough macronutrients, micronutrients won’t save you.

Adequate energy intake is key for weight, recovery, and daily energy.

Active people often struggle to get enough energy during busy days. If you rely only on veggies, chicken breast, low-fat cottage cheese, and beans, you’re making it harder than it needs to be.

Believing you must eat only the healthiest foods creates unnecessary restrictions and possibly a poor relationship with food.

As Michal said, “I felt like I could only eat grass and salad.” He lived in a strict calorie deficit. The result? He didn’t gain weight, but his energy and fatigue worsened.

Many health-conscious people train like pro athletes—7+ hours a week—eat healthy, but eat too little.

When Michal realized he didn’t need to eat only veggies and protein, it was liberating. He didn’t have to avoid bread at the store. He could enjoy ice cream and cake with his daughter. And he didn’t have to choose between training and family—he had energy for both.

To sum up: quality food is important, but don’t forget quantity. If you want to perform, you need premium fuel—but you won’t get far with a half-empty tank.

Which brings us to the third pillar.

Timing

You probably sense that eating the same number of calories in one meal versus six isn’t the same. Despite what you hear, there’s no perfect number of meals—but for most people, 3–5 meals a day works well (3 main meals and smaller ones as needed).

Timing of meals contributes to:

• to the feeling of hunger and fullness – going too long between meals can make you extra hungry
• metabolism of nutrients – we metabolise food worse in the evening compared to mornings.
• food choices – we tend to eat crap in the evening

For athletes, timing is critical:

• Before and during training to maximize performance. Your body can’t convert fuel into usable energy instantly. Eating the wrong foods, or at the wrong time delays glucose availability, which means less energy output and slower digestion. The result? Lower performance, more fatigue, bloating or stomach discomfort and reduced recovery.
• After training to maximize recovery

You don’t need to consume protein within an hour post-workout. But there is a 40-minute window for carbohydrate intake after training. If you want to maximize recovery, carbs post-workout should be a priority.

A friend, a seasoned hybrid athlete, made a rookie mistake.

He went on a diet and cut carbs—down to 200–300g per day. He felt tired but thought, “That’s just dieting.” Then he added 70g of carbs post-workout and said:

“I was sore but didn’t want to gain weight. Total nonsense. You think cutting carbs means losing weight. But you feel more sore. So I thought, logical—it’s the diet. But I missed the 40-minute window. Now I take 70g of carbs with 20g of protein right after training and I’m happy 🙂 I even look better and have better body composition.”

This is what most people and fitness content overlook.

The biggest obstacle isn’t information—it’s mindset.

Most people I’ve worked with, including myself, don’t get stuck because they don’t know how much to eat. After a few tweaks, they find a system for meal prep.

We often fear perceived consequences and lack the skills to overcome them. So we make choices that feel comfortable short-term but hold us back long-term.

“Should I eat that much?” (But what if I gain weight?)
“I don’t need to eat if I’m not hungry.” (But what if I get bored or anxious?)
“What if I’m hungry?” “What if I try and still fail?”

One of the main reasons we stay stuck is that we don’t actually do things differently—even if we say we do.

If you’re stuck, it’s not just because you lack discipline or information—it’s because you lack the skills to move forward.
