Our Story

From a Sunday blog post to a platform that reads every study for you.

10+ years. 40,000 members. 2.4 million meal plans. And we just fundamentally changed how we do everything.

In 2013, on a rainy Sunday afternoon, Mark van Oosterwijck published his first nutrition blog post. It was optimized for Google — not for truth. The right keywords, the right structure, the right length. It was exactly what the algorithm wanted. And it worked.

The blog grew fast. Within a few years, FitChef was one of the biggest health platforms in the Netherlands — nearly a million monthly readers. Cookbooks sold 50,000+ copies. A meal plan platform launched and grew to 40,000 members. By every measure, it was a success.

But something nagged. The content was popular — but was it right? Was it truly grounded in what the research said? Or was it, like everything else online, built to perform rather than to be accurate?

For years, there was no good answer to that question. Reading every study, reviewing every claim, preserving every nuance — no editorial team could do that at scale. It was physically impossible. And then AI changed everything.

Not by generating cheaper content. By making it possible to do the work that nobody could do before — reading thousands of pages of research for a single topic, extracting every claim, checking every number against the source paper, and catching every distortion before it reaches you.

That's the FitChef you're looking at now. Same mission — make nutrition simple and accessible. Completely new foundation — every claim grounded in reviewed research.

Content and Meal Plans. Becoming One System.

FitChef started as content. Then it became meal plans. Now the two are becoming the same thing.

For over a decade, we've built one of the most personalized meal plan platforms online — 1,000+ recipes, smart shopping lists, family scaling, dietary flexibility from vegan to high-protein, and plans that adapt as you make progress. That's the engine.

Now we're building the intelligence layer on top. Our Grounded Truth Map — every reviewed claim, synthesized from multiple studies — is becoming the source that powers your meal plan. When research shows that trained athletes benefit from 1.6–2.2g/kg of protein, that finding doesn't just sit on a page. It becomes the logic behind your Tuesday dinner.

We're not done. This is an iterative process we work on every day — connecting what the research says to what you eat. But the foundation is live, the pipeline is running, and every week the system gets smarter.

Answer a few questions. Get your personalized plan in under a minute.

Breakfast, lunch, dinner, snacks — tailored to your goals and diet. Swap meals you don't like. Add family portions. Access 1,000+ recipes. Every recommendation moving toward being backed by reviewed research.
