Introduction to the NaturalSlim Program
"It's not that you have 'little willpower' or lack discipline. Anyone who makes a huge effort and never sees results will give up."
Frank Suárez, The Power of Your Metabolism
Understanding your metabolism comes first
Many people make the effort, switch plans again and again, and still don't see the change they're after, or live with little energy without knowing why. Frank Suárez called this a "slow metabolism".
Food is the fuel, and your metabolism is the engine that turns it into energy. If you don't know how that engine works, changing the fuel blindly rarely solves the problem.
That's why the Personal Program starts with what almost nobody explains to you: how your metabolism works and what slows it down. You can never solve a problem you don't understand.
A consultant at your side, every week
Your Certified Metabolism Consultant™ works with you one to one, from the first call until you graduate. This is what you do together:
1. Set a realistic, measurable goal, so you always know where you're heading.
2. Adapt the way you eat to your nervous system type, passive or excited, with the 3x1® Diet, and drink the amount of water your body needs.
3. Learn which foods suit you and which don't, so you can make your own decisions.
4. Understand how and when to take the food supplements included in the program.
5. Review your progress every week and answer your questions until you reach your goal.
If you're looking for clear guidance and someone who really stays with you, that's what the NaturalSlim® Personal Program offers.

"First of all, I thank God, and I am grateful for the opportunity to get to know NaturalSlim. In October 2025 I started watching Frank Suárez's videos, and there I found answers.
On February 25, I contacted my consultant, Magnerys, who conducted my metabolism evaluation. I followed the program step by step and was very committed to the process. Today, I can say and testify that my journey was a complete success.
Thank you, thank you very much! I will recommend NaturalSlim as many times as necessary."

How the Personal Program works
The first step is a free telephone evaluation of your metabolism with one of our Certified Metabolism Consultants™. From there, your consultant guides you with a plan adapted to you and follows your progress every week.
The program rests on the 4 factors of the NaturalSlim® System: knowledge, eating for your metabolism, food supplements and a consultant at your side.
From the first call to your graduation
Your consultant adapts the plan to your goal, your nervous system type and the foods that don't agree with you.
You receive the NaturalSlim® Personal Program Guide, which explains every step, and access to the video The Truth About Slow Metabolism. In every consultation you learn something new about how your body works.
You graduate when you reach the goal you set with your consultant. You receive your graduation certificate and can join the "Hall of Fame".
"My name is Diana. I joined the NaturalSlim program at a time when my body had changed a lot and my energy and sleep were poor. Thanks to the NaturalSlim program and the weekly support of my consultant Liliana (her encouragement and unconditional guidance motivated me enormously), I reached the goal I'd set when I started, which means a great deal to me, and I feel happy and incredibly grateful. I want to share that drinking water properly and taking minerals such as magnesium and potassium, among the other supplements, became essential for me and helped me a lot throughout the process. Thank you so much for changing my quality of life."

The 3x1® Diet: a lifestyle, not a diet
No forbidden foods
The 3x1® Diet doesn't forbid any food. It rests on a simple proportion for every plate: three parts Type A foods and one part Type E foods. Your Guide and your consultant explain which foods are which.
There's no calorie counting and no going hungry. The body is alive: it learns and adapts.
What you learn is based on the work of Frank Suárez (1950-2021), founder of NaturalSlim and author of The Power of Your Metabolism.

Food supplements are not a substitute for a varied and balanced diet and a healthy lifestyle. Take each supplement as stated on its label. Do not exceed the recommended daily dose. Keep out of reach of young children. If you are pregnant, breastfeeding or taking medication, consult your doctor before use.

How long does the program take?
It has no fixed length. You set your goal with your consultant and you work on it together every week until you reach it. How long that takes depends on where you start, on your goal and on how consistently you follow the program. Regular exercise, at least 3 times a week, fits in well alongside it. When you reach your goal, you graduate and receive your certificate.
Will I get a fixed menu for every day?
No. The program teaches you to decide for yourself what to eat, instead of relying on a list of breakfasts, lunches and dinners. Once you can tell Type A foods from Type E foods, you can put together your own menu. Your Personal Program Guide includes the expanded list of Type A and Type E foods.
Our aim is for you to learn enough to keep going without needing us or anyone else. If you have questions, your consultant will clear them up, and on the MetabolismoTV YouTube channel you will find videos in which Frank Suárez explains the 3x1® Diet.
When can I start exercising?
If you have enough energy, the sooner the better: exercise is highly recommended and fits well with the program. If you have a health condition or haven't been active for a while, ask your doctor what kind of exercise suits you and build up gradually. Your consultant will help you fit it into your routine.
