Our slimming programs for every goal
Now that you know more about the method, let's concretely analyze which weight loss program matches your ambition. Here are the solutions classified by weight loss goal.
For rapid weight loss: –3 kg and –6 kg
-
The 14-day program (-3 kilos) is ideal for quickly correcting a few excesses or refining your figure before an event. It offers an effective boost to restart weight loss.
-
The 30-day program (-6 kilos) allows you to go further, with visible and motivating weight loss, without committing to too long a duration.
These two kits are turnkey and include all the necessary sachets as well as the tracking guide.
For a visible transformation: –10 kg and –15 kg
- The 45-day program (-10 kilos) is for those who want a real transformation, beyond a simple adjustment. It allows you to lose weight while initiating a permanent change in eating habits.
- The 70-day program (-15 kilos) is designed for a more significant transformation. Its duration helps secure weight loss and effectively prepare the stabilization phase.
The method supports your body throughout this transition, without abrupt disruption.
For a permanent and impressive change: –20 kg
-
The 90-day program (-20 kilos) is the most comprehensive journey. It is designed for people determined to regain control of their weight permanently, through the progressive integration of the 4 Cetofine phases.
The kit includes all the high-protein sachets, a detailed weight loss guide and the necessary supplements to support the body throughout the program.

The Cetofine method: a structured high-protein approach
The method is based on a strict high-protein weight loss program. The principle is mechanical: carbohydrates and lipids are drastically reduced to force the body to draw from its fat stores, thereby triggering ketosis.
This mechanism offers an immediate dual benefit. You see rapid weight loss from the start, while protecting your muscle mass thanks to the massive intake of high biological value proteins.
Forget magical promises, here we're talking about nutritional science. This supervised protocol is specifically designed for people with a weight overload of at least 2 kg, seeking real effectiveness.
The 4 tiers: a progressive journey for permanent results
The Cetofine method is based on 4 progressive levels, designed to lose weight and then permanently stabilize results. This structure is the key to avoiding the yo-yo effect.
-
Level 1 and Level 2 trigger weight loss. They combine high-protein sachets and progressive reintroduction of a protein meal.
-
Level 3 and Level 4 ensure transition and stabilization, with a controlled reintroduction of starches to relearn how to eat without regaining weight.
This four-stage organization allows a smooth transition to permanent food autonomy.
A solution designed and validated by nutrition experts
Each Cetofine program is developed with qualified nutritionists, according to strict quality and safety criteria. The compositions, protein intakes and progression through the levels are designed to respect your metabolism.
This expertise is reflected in the included weight loss guide, a true roadmap that accompanies you day by day, without approximation, to follow the method with complete confidence.
With the Cétofine 21 program, more than 30,000 people have lost weight and achieved their goals.
We distribute excellent quality products and ensure that all our sachets have a chemical index above 100.
How to choose your slimming program?
Now that the method is clear, it's a matter of finding the path that precisely matches your needs.
Define your weight loss goal
The first step is to set a realistic goal. How many kilos do you want to see disappear on the scale? This question is fundamental to choosing the right path.
Cetofine adapts to all profiles: from a small loss of -3 kg to refine your figure to a more substantial transformation of up to -20 kg. Know that each goal has its dedicated program.
The choice of your final goal will directly determine the program duration. It's an implacable logic.

"Despite all the diets I've tried, I had never heard of this one before. It was while watching YouTube that I learned about this high-protein diet. I'm in my first week, quite easy to follow, and already lost 2 kg. I am completely satisfied."

"My first experience with it. The 30-day pack was satisfactory, 6 kgs in 4 weeks with one cheat the first week, no feeling of hunger"

Choosing the duration suited to your goal
Each weight goal corresponds to a specific weight loss program duration. This is the mechanism that ensures progressive and perfectly controlled weight loss.
Programs range from 14 days for short-term goals to 90 days for the most significant ones.
Here is a table to quickly visualize the correspondence between goals and the time required:
| Your goal | Program duration | Recommended program |
|---|---|---|
| Lose up to 3 kg | 14 days | Weight Loss Program – 3 kilos |
| Lose up to 6 kg | 30 days | Weight Loss Program – 6 kilos |
| Lose up to 10 kg | 45 days | Weight Loss Program – 10 kilos |
| Lose up to 15 kg | 70 days | Weight Loss Program – 15 kilos |
| Lose up to 20 kg | 90 days | Weight Loss Program – 20 kilos |
A program designed for you: man or woman
Protein needs are not the same for men and women. That's why Cetofine offers separate kits for each.
Here's the concrete difference. Men's programs contain a larger number of high-protein sachets to meet higher energy and muscle needs.
This distinction ensures optimal effectiveness and better comfort during the program.

How to choose the right slimming program for your profile
If you haven't yet defined a specific weight loss goal or if you don't know how many pounds to lose, BMI will provide you with an excellent starting point
.
BMI (Body Mass Index) is a reliable indicator that allows you to assess your build and better understand your weight situation.
This indicator takes into account your height and weight to determine whether you are in the normal weight, overweight or obesity zone. It constitutes an objective first basis to guide your weight loss journey.
At Cetofine, BMI calculation is not just theoretical data. It allows you to:
-
better assess the extent of necessary weight loss,
-
identify the most suitable weight loss program,
-
choose a duration consistent with your goal and metabolism.Before choosing a weight loss program, it is essential to start from a reliable indicator.
Who is the Cetofine high-protein weight loss program suitable for?
The Cetofine high-protein weight loss program is designed for people who want to lose weight effectively.
It is particularly suitable if you have at least 2 to 3 kilos to lose, up to more significant goals that can go beyond -20 kg, and you are looking for a serious, structured and permanent solution.
This program is particularly suitable if you:
-
have already tried low-calorie diets without permanent results,
-
want to target fat mass loss, without sacrificing your muscle mass,
-
are looking for a supervised weight loss program, based on a proven method,
-
want to avoid the yo-yo effect thanks to an integrated stabilization phase,
-
need a clear framework, simple to follow on a daily basis, without improvisation.
It is also very relevant:
-
after 40 years old, when metabolism naturally slows down,
-
in case of frequent snacking or cravings difficult to control,
-
if you want to regain real eating habits, and not follow yet another temporary diet.
The Cetofine weight loss program is not a miracle solution.
It's a proven nutritional strategy, designed for those who want concrete and permanent results.
Who is the Cetofine weight loss program not suitable for?
Even though the Cetofine high-protein method is safe and supervised, it is not suitable for all profiles without prior medical advice.
The program is not recommended in the following situations:
-
pregnant or breastfeeding women,
-
people suffering from renal, hepatic insufficiency or severe metabolic disorders,
-
people under heavy medical treatment without prior validation,
-
unstabilized eating disorders,
-
adolescents in full growth.
In these situations, a medical opinion is essential before considering a high-protein weight loss program.
Transparency is part of Cetofine's commitment:
an effective program is above all a program adapted to your personal situation.
Why choose Cetofine over another weight loss program?
All weight loss programs promise weight loss.
Very few explain how, why, and especially how not to regain weight.
The Cetofine difference is based on an expert, measurable and structured approach, where many solutions settle for a simplified commercial framework.
An expert nutritional approach, not a marketing concept
The majority of weight loss programs on the market are built around a commercial model: ready-to-eat meals, monthly subscriptions, promises accessible to all.
At Cetofine, the approach is different. The program is based on the physiological mechanisms of metabolism, used for years in clinical nutrition.
The goal is not only to reduce caloric intake, but to modify the energy source used by the body. By sharply reducing carbohydrates and increasing protein intake, the body is led to draw directly on its fat reserves.
Observed result: an average loss of 1.5 to 3 kg per week in phase 1, mainly fat mass, not water or muscle.
A structured 4-step protocol, where others remain static
Many programs apply the same rule from the first to the last day.
This linear approach is one of the main causes of the yo-yo effect.
The Cetofine weight loss program is deliberately divided into 4 progressive phases, each having a specific role:
Strict diet
Trigger fat mass loss
Mitigated diet
Continue fat mass loss
Transition
Support the dietary transition
Stabilization
Stabilize weight permanently.
The Transition and Stabilization phases represent up to 30% of the total program, a point often absent from competing solutions.
This is what allows you to stabilize results once the goal is achieved.
A structured high-protein program, not a vague low-calorie plan
Reducing calories without strategy often leads to fatigue, hunger and muscle loss.
Cetofine relies on a high and controlled protein intake, with high biological value proteins, to maintain satiety and protect muscle mass.
During the strict diet phase, carbohydrate intake is kept below the threshold of 30 g per day, a necessary condition to promote ketosis.
This metabolic state acts as a natural appetite suppressant, which explains why the majority of users experience a significant reduction in cravings from the first days.
Unlike a conventional low-calorie diet, weight loss is more targeted, more visible and more motivating.
Real, structured support, not automated follow-up
Finally, Cetofine is not limited to an app or standardized messages.
Each program includes:
-
a detailed weight loss guide, designed by nutrition experts,
-
a clear method explaining what to do at each phase,
-
a team available by email or by phone to support and guide you if necessary.
You know exactly what to eat, when and why, without improvisation.
This framework greatly reduces dropouts and increases chances of long-term success.

FAQ - Cétofine 21 weight loss program
How to lose 10 kg quickly with a suitable program?
The Cetofine weight loss program 45 days is recommended for a goal of –10 kg. It relies on a strict high-protein diet at the start to trigger ketosis, then on transition and stabilization phases to permanently maintain results.
What is the best weight loss program to reach my goals?
The best program is the one that matches your weight loss goal and your profile (male or female). Cetofine offers turnkey kits from 14 to 90 days to lose between 3 and 20 kilos, including high-protein sachets, supplements and nutritional guide, for a structured and effective approach.
What does the 4-step method consist of?
The Cetofine method is based on 4 progressive steps. The first two trigger weight loss, the next two allow for dietary transition and stabilization. This structure is essential to avoid the yo-yo effect (weight regain).
What type of diet is most effective for losing weight quickly?
The high-protein diet is one of the most effective. By severely limiting carbohydrates at the start, it promotes ketosis, a metabolic state that helps burn fat mass while preserving muscle mass.
Which foods should be avoided during the attack phase?
During Step 1, you must temporarily exclude starches, fruits, regular dairy products, sugars and alcohol. The diet is based on high-protein sachets and authorized vegetables. These foods are gradually reintroduced later.
What is the secret to losing weight permanently?
The secret lies in combining rapid weight loss with a supervised stabilization phase. Steps 3 and 4 allow you to relearn how to eat and anchor results long-term. No secret: after your diet, you will need to adopt good eating habits.
What triggers the fastest weight loss?
The ketogenesis. In the absence of carbohydrates, the body uses its fat reserves as an energy source, which leads to rapid weight loss, often 2 to 2.5 kg per week in the strict phase.
What physical activity should be combined with the weight loss program?
During the first steps, gentle activity such as walking is recommended. During the transition and stabilization phases, more regular activity helps to tone the figure and maintain ideal weight. Most importantly, engage in physical activity after the protein diet and regularly.
