The 15-Day Cétofine Program — The expert method for effective weight loss

The Cétofine method is based on ketosis, a natural mechanism of fat burning.
By following the progression of steps 2, 3, and 4, you trigger rapid weight loss while preserving your muscle mass and vitality.

The 3 steps of the 15-day protein diet

As part of a 2-week diet, you do not perform Step 1: Strict protein diet.

  • Step 2 – Mixed protein diet (days 1 to 7)
    Rapid weight loss phase: combination of high-protein sachets and protein "slimming" meals, composed of dietary proteins.
  • Step 3 – Transition (days 8 to 11)
    Reintroduction of complete breakfast, continued weight loss without fatigue.
  • Step 4 – Stabilization (days 12 to 14)
    Gradual return to normal eating, anchoring results without yo-yo effect.

  • Day 15 – Assessment and gentle resumption: This final day allows you to make a gradual transition to your daily diet, while maintaining the benefits of the 15-day Cétofine program. It's time to measure your results, adjust your meals, and prepare for long-term stabilization.

The -3 kilos kit from Cétofine 21 contains enough sachets to follow 14 days of complete program.

How does the 15-day protein diet work?

The principle is based on a precise balance between proteins, fiber, and essential nutrients.
During the first week, your body gradually enters ketosis, a natural phase where it uses its fat as energy.

During the second week, you continue to lose weight by stabilizing your appetite and gradually reintroducing essential food groups like carbohydrates and lipids.
Result: lasting weight loss, without disrupting your metabolism, without fatigue.

Frequently asked questions about the 15-day protein diet

Can you really lose weight in 2 weeks?

Yes. By triggering ketosis, your body starts burning its stored fat from the first days.

Result: visible weight loss, without muscle loss.

Is the diet safe?

Yes, provided you are in good health and follow the recommendations properly. The Cétofine 21 high-protein diet is rich in proteins: you must therefore drink plenty of water, consume vegetables for vitamins and minerals, and take a multivitamin supplement if needed. This ensures safe and balanced weight loss.

Will I be hungry during this 2-week program?

This is possible, especially in the first days of the diet; although Cétofine high-protein meals provide lasting satiety and prevent cravings. Once in ketosis, you will lose weight without hunger or fatigue.

What happens after the 15 days?

Once the stabilization phase (Phase 4) is complete, you will have lost your 3 kilos. Then, it's up to you to eat a balanced diet to maintain your new weight.

Do you need to exercise?

Gentle activity (walking, yoga, stretching) is enough to optimize the effects of the diet without tiring the body.

Don't do too intense exercise during step 2: Mixed protein diet since you are depriving your body of carbohydrates.
