How does our 1-month slimming program work?
The Cétofine 21 high-protein diet consists of 4 key stages, designed to activate, prolong and stabilize your weight loss:
Protein diet - Day 1 to 10
Attack phase: your body enters ketosis, directly burning fats. You consume high-protein sachets and authorized vegetables.
Mixed diet - Day 11 to 16
Weight loss continues: you reintroduce a slimming meal based on natural proteins (meat, fish, dairy products) while keeping your protein sachets.
Transition - Day 17 to 21
Your metabolism balances: gentle reintroduction of essential carbohydrates to prepare for stabilization and avoid metabolic shock or fat storage.
Stabilization - Day 22 to 30
Gradual return to complete nutrition, with maintenance of target weight and learning good eating habits. The secret to avoiding the yo-yo effect.

How many kilos can you really lose in 1 month?
Weight loss in 1 month depends on many factors: your basal metabolism, your level of physical activity, and above all, the type of weight loss program you follow.
With the Cétofine 21 method, the average observed among our customers is around 6 kilos in 30 days, thanks to controlled triggering of ketosis, a high-protein diet, and structured nutritional support.
This is a targeted loss on fat mass, without hunger sensation or muscle wasting.
Do you want to lose 5 kilos in 1 month?
This is entirely possible, especially if you are in a food rebalancing approach and following a protocol as structured as Cétofine.
Goal –10 kilos in 1 month: is it realistic?
Losing 10 kilos in one month requires a much stricter strategy, often reserved for specific contexts (significant overweight, medical supervision…). Cétofine can initiate this dynamic of rapid loss during the first weeks. On average, you will observe a weight loss of 10 kilos in 45 days.
In all cases, Cétofine 21 offers a progressive and secure framework, with men's/women's packs adapted to your goals. The key to permanent loss is not speed, but consistency and stabilization, two pillars at the heart of our method.

Frequently asked questions about weight loss in 1 month
Can you really lose 6 kilograms in 1 month?
Yes, it is entirely possible with the Cétofine 21 method.
The average weight loss observed in our clients is between 4 and 6 kilograms in 30 days, depending on metabolism and adherence to the program.
The Cétofine high-protein diet acts directly on fat mass, not on muscles. That's why the silhouette slims down quickly, without feeling fatigued.
Will I be hungry during my 30-day slimming program?
No. The secret of the Cétofine method is based on the natural satiety of proteins.
The protein sachets are designed to stabilize blood sugar and reduce snacking cravings.
You will have up to 5 meals per day for women and 6 for men, accompanied by unlimited allowed vegetables.
What is the difference between the Women's kit and the Men's kit?
Both programs follow the same protocol (4 phases), but:
- The Women's Kit (112 sachets) is adapted to moderate caloric intake, optimized for gentle and harmonious weight loss.
- The Men's Kit (140 sachets) includes more preparations to support a faster metabolism and higher energy needs. (an additional sachet at 10 PM)
Result: in both cases, an average loss of 6 kg and a controlled return to dietary balance.
Which foods can I consume with the Cétofine diet?
Each slimming kit comes with a complete list of allowed vegetables, rich in fiber and low in carbohydrates.
For example: broccoli, zucchini, spinach, mushrooms, peppers, cabbage…
These vegetables accompany your protein sachets to create real satisfying and varied meals.

How to choose your vegetables properly during the high-protein diet
How to avoid regaining weight after the program?
This is one of the great advantages of the Cétofine method: it includes two rebalancing phases (Transition and Stabilization).
These stages allow your metabolism to regain its natural rhythm, while gradually reintroducing carbohydrates and lipids.
Thanks to this process, stabilization is permanent, without yo-yo effect.
Additionally, our team remains available for personalized follow-up after your diet.
Can I exercise during my weight loss?
Yes, but it's not mandatory.
During the active phase (Phase 1), it is recommended to limit intense physical activity.
From the Transition phase, brisk walking or light stretching promotes circulation and fat elimination.
Cétofine tip: let your body adapt to the diet rhythm before increasing intensity.
What to do if I want to continue after 1 month?
After this program, it is recommended to respect a 15-day break before restarting the method, beginning at Phase 1 or Phase 2, depending on your goals and how you feel.
For weight loss greater than 6 kilograms in 1 month, we advise you to opt directly for the -10 Kilogram Slimming Kit in 45 days, better suited for more significant and gradual weight loss.
Are Cétofine products safe?
Absolutely. All our protein sachets are made from high biological value proteins with low sugar content.
Our supplements (Gérimax, Pineapple fat burner) are formulated according to European food safety standards.
No medication, no chemicals, just controlled and effective nutrition.
