XL2M – From XL to M

XL2M Weight Loss is a data-driven dashboard app developed from a real personal transformation and built as a live AI learning project.

The Problem

Obesity is not an aesthetic issue. It is a serious health risk with real consequences such as heart attacks and strokes.
At the same time, people affected by overweight often experience stigma, bullying, and discrimination – especially at a young age.

Most fitness apps are designed for people who are already fit. They focus on performance, not on the difficult and often
frustrating process of long-term weight transformation. What is missing is a clear, understandable structure for people
who are starting from zero.

The Idea Behind XL2M

XL2M started as a personal self-experiment. In 2023, I lost 37 kilograms using handwritten tables and structured
self-tracking, supported by nutritional expertise. These handwritten logs later became the data foundation for this project.

XL2M translates this experience into a digital dashboard that focuses on clarity, structure, and progress visibility
rather than pressure or motivational slogans.

How It Works

XL2M visualizes weight change as a tactical process. Users log their weight data in a simple combat log, while the
dashboard provides clear visual feedback through BMI zones, risk levels, and a color-based progress bar showing the
path out of obesity risk.

A calendar view helps structure short-term tactical goals. The design is inspired by martial arts belt systems and
competition preparation: clear stages, discipline, and measurable progress.

AI as a Learning Tool

XL2M was developed using Vibe Coding and AI-assisted workflows. It serves as a positive example of applied AI,
demonstrating how artificial intelligence can help structure real-world problems without replacing human responsibility.

The project is used as a live case study in AI workshops for students, teacher trainings, and educational formats
that combine technology, design, and critical reflection.

Project Status

XL2M is currently in a founder-tested beta phase. The app is continuously refined through workshops and educational use.
It does not make medical promises and is not a substitute for professional healthcare or medical advice.

Why This Project Exists

XL2M is not about optimization or hustle culture. It is about understanding how technology – especially AI – can support
people in regaining control, building awareness, and learning through transparent processes.

From obesity to app prototype. From handwritten notes to AI-assisted learning.
