One of the key things we ask our clients who do the 90 Day Challenge with the goal of fat loss or muscle gain is: How well do you sleep? This factor is often underestimated. What may have become “normal” over the years is in no way something that has to be normal.
Getting up several times a night to use the bathroom? Needing more than 10 minutes to fall asleep? Waking up in the middle of the night and not being able to drift off again?
We hear things like this all the time – and they can be one reason for slow or stalled progress. In this article, we’ll look at some possible causes and show you how to optimise your sleep.

We’re often asked which healthy small bites we recommend when hunger suddenly strikes. First things first: with regular meals in the right combination, you can prevent cravings most effectively.

The fitness world can feel like the Wild West. One influencer swears that fasting is the only way to get lean. Another promotes an “ancient” exercise that will supposedly give you a shredded core in three days. Meanwhile, your friend just bought a fat-burning tea because someone on TikTok promised it was “doctor approved.” If you want to navigate this chaos without wasting your time, money, or health, you need one thing above all else: scientific literacy (OECD, 2017; UNESCO, 2017).

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.
