LEAN MODE · GLP-1 HANDBOOK + TOOLS
The guide for anyone
on the weight-loss injection.
Start informed, not in the dark. Before or during the injection, understand what I did in practice: food, training and routine.
Many people start the injection without knowing what to do about food, training and daily life. Lean Mode brings together what I did on my journey (120 → 75 kg) and the tools to organise yours — all in one member area.

The author's journey: 120 → 75 kg. An individual experience, not a promise of results.
FIRST OF ALL
Why Lean Mode?
I'm Leandro, and I weighed 120 kg. When I started on the weight-loss injection, I had no idea what was coming. In the end I lost over 40 kg while keeping muscle — and then I completed two professional certifications here in Germany, where I live: one as a Fitness Trainer and one as a Nutrition Consultant.
So I combined my hands-on experience with what I learned in theory and gathered here everything you need: from what to do on your first day at the gym, to what to eat while using the injection, to how to measure your results. It's an in-depth guide, with practical tips and reflections on changing your lifestyle.

Straight from my Instagram
These questions land
in my DMs every day.
Ever since I started sharing my transformation, I answer them one by one. They are always the same doubts — the ones no doctor has time to answer during a consultation.
"What did you eat day to day when you started the treatment?"
Nutrition module
"Which blood tests did you ask for and why?"
Bloodwork guide
"How much did you lose in week 1? And week 2?"
My case, week by week
"Which protein do you recommend? How much per day?"
Protein calculated for you
"I lost 12 kg in the first year… but I have been stuck for months. What do I do?"
Calories and training recalculated
"I am losing weight, but am I also losing muscle?"
5 workout plans
In the DMs, each answer fits in three lines.
In Lean Mode, each one became a full module — with what I ate, how I trained and what the bloodwork showed.
The manual
Leandro's Journey: the 5 modules.
The manual is a single read, organized in 5 modules that cover the other half of the treatment — the part a fifteen-minute consultation does not hand you.
Understand what is happening in your body.
What to expect at each stage of the process, what is usually temporary and what deserves a conversation with your doctor. You stop guessing.
Eat right even without hunger.
Real meals with timings, calories and protein calculated. What to prioritize when the appetite disappears, and why.
Lose fat. Not muscle.
5 complete workout plans, 3× to 5× per week, with PDFs to download. From beginner to advanced, built to protect muscle mass in a deficit.
Know what to track beyond the scale.
Which tests to ask for, how to read each marker, and how to use photos, measurements and strength to know if it is working.
My case, from 120 kg to 75 kg, documented.
52 weekly weigh-ins, 24 blood markers before and after, and the milestones of each phase. The real account behind the whole method.
Individual results may vary.

My story
I was the 120 kg dad
who could no longer keep up.
October 2024, 120 kg. My son would run and I could no longer keep up.
14 months later: 75 kg, with muscle and energy. The whole path is gathered in Lean Mode.

And since I do not trust before-and-after photos, I documented the inside too. Look at what the blood shows.

First of all, what this is
Lean Mode is a lifestyle-change manual.
I lost 45 kg and documented every step: what I ate, how I trained, how I slept, what I changed in my routine and what the bloodwork showed across the whole process. That record became this playbook.
If you are on medical treatment to lose weight, you have probably noticed that nobody explains the other half: the food, the training and the routine. That part is exactly what is here, and that is why this material was written with you in mind.
What Lean Mode is
- ✓A documented account of the experience, from the first to the last kilo, turned into a practical manual.
- ✓A nutrition guide: what to eat, how much protein, how to structure your day.
- ✓A training guide: how to keep muscle while the weight drops, from beginner to advanced.
- ✓A lifestyle guide: routine, social life, sleep, and what to track beyond the scale.
What Lean Mode is not
- ✕Not content about medications, and it does not indicate, recommend or explain any treatment.
- ✕It does not discuss doses, brands or how to use anything.
- ✕It does not replace a doctor, a dietitian or clinical supervision.
- ✕It does not promise results: it shows the method that worked for one person, with open data.
Decisions about any treatment are exclusively yours and your doctor's. What is on your plate, in your week and in your routine — that is what this playbook is about.
