Nutrition & Metabolism

Searching for nutrition tips in the “online jungle” can make your head steam. I’ve already explained the 10 most common nutrition myths. Now let’s get more specific and focus on the fitness goals of losing fat or building muscle—and the nutrition strategy that fits each. That raises questions like: Where should I start? What’s right and what’s wrong? Fast and radical, or long-term and sustainable? Maybe YOU have asked yourself these questions too. In this blog post, I’ll help you find answers by giving you a science-based foundation so you can make decisions tailored to your individual needs. Let’s get started.

Let’s get one thing straight: there’s no magic in eating animals, and there’s no halo over kale either. Nutrition isn’t religion, it’s biology. And if you’re serious about health and performance, you need to cut through the ideological noise and get your facts right. Especially when it comes to plant-based diets and protein. So let’s talk about veganism, vegetarianism, and what happens when you stop eating meat. Spoiler: It’s not all rainbows and ethical superiority. But it’s also not the nutritional apocalypse that some steak-worshippers scream about.

I admit – the title is provocative. But that’s exactly how dogmatic and black-and-white today’s discussions around nutrition have become. Whether it’s about meat, dairy, or soy, things are quickly labeled as either “good” or “bad” – with little room for nuance. If you want to understand why your body needs protein and how much is necessary for fat loss or muscle building, this blog post is for you. This article focuses specifically on meat as a source of protein. Just last week I read that chicken, when consumed above a certain weekly amount, is now considered harmful. Until now, only excessive red meat was viewed as problematic. And now even white meat is under fire? Right in the middle of the barbecue season! All the more reason to shed some light on this topic.

We are fitness experts. But when it comes to losing weight or building muscle in a sustainable and healthy way, other factors are just as important as training. One of these, along with a good night’s sleep, is your diet. That’s why we’re going to look at some of the basics of nutrition and show you a sample day from Marc’s life.

Creatine may not be a household name, but anyone starting strength training will eventually ask themselves: “Should I take creatine?” This question often arises in the context of strength training and bodybuilding. However, recent research shows positive results not only in muscle growth and strength gains but also in cognitive performance. Read everything about creatine here.

Who hasn’t heard of Vitamin D? At the latest since the Covid pandemic, everyone should have come across it. Several studies have shown that better vitamin D levels are associated with a lower risk of severe illness.
But what exactly is Vitamin D? How is it produced, and what functions does it serve? How and when should it be tested, and what are considered “good” values? In this blog post, we answer all these questions.
