Why is 3 months the ideal duration to lose 20 kilos?
Losing 20 kilos represents a significant goal. For this weight loss to be effective, controlled, and permanent, the Cétofine 21 method is based on a structured progression in 4 stages. Over a period of approximately 3 months, you give your body the necessary time to trigger weight loss and then stabilize results without the yo-yo effect.
During the first weeks (Stage 1 and Stage 2), weight loss is rapid thanks to ketosis: the body draws from fat mass while preserving muscle mass through the high intake of high biological value proteins. This phase allows you to achieve approximately 70 to 80% of your goal.
The following weeks (Stage 3 and Stage 4) are just as essential. They allow for the gradual reintroduction of carbohydrates and fats, learning new dietary reflexes, and consolidating your new weight. This precise structure secures your transformation and prevents weight regain.
In 3 months, you don't just lose 20 kilos:
you permanently change your metabolism and eating habits, with a clear, gradual, and medically supervised framework.
The expert method in 4 phases (over 3 months)
The structure is based on 4 successive phases. Together, they form a structured method whose steps are all essential.
Phase 1 – Strict diet: 5 weeks
Triggering phase. Your body enters ketosis and mobilizes lipid reserves.
Proteins ensure satiety and protect muscle mass, like clean fuel that powers an engine.
Phase 2 – Mitigated diet: 2 weeks
Weight loss continues, but diet becomes richer.
Natural proteins (meat, fish, eggs) make their return.
This phase acts as a bridge. You progress without abrupt disruption.
Phase 3 – Transition: 3 weeks
Progressive reintroduction of starches, fruits and low-fat dairy products.
This phase works as a buffer: it absorbs the shock of too rapid dietary return and prevents sudden regain.
Phase 4 – Stabilization: 3 weeks
Return to a balanced diet.
Your new weight becomes the reference, like a new permanent baseline.
You have adopted new eating habits that you must continue to put into practice.
Did you know?
Most weight regain occurs after diets that are too short. Phases 3 and 4 are designed precisely to anchor your results and limit the yo-yo effect.
The 3-month Cétofine turnkey program
The Cétofine program is based on a simple principle: guiding without constraining. For 90 days, you know exactly what to eat and when.
High-protein sachets, structured snacks and phase-by-phase progression provide a clear and precise dietary framework. You follow a pre-defined program, without having to improvise or count constantly.

How does a 3-month weight loss program work?
The secret lies in the balance between proteins, fiber, hydration and micronutrients.
Proteins prolong satiety and support muscle mass.
Ketosis stimulates fat burning.
Phase-by-phase progression secures the program exit.
Over 3 months, the loss is visible and measurable. But above all, it becomes permanent. You are not fighting against your body: you are guiding it towards a new balance.
