The Proteika Program 18 diet has disappeared, but its results remain sought after. Cétofine 21 is the modern alternative: a 4-step method and high-protein products for rapid and permanent weight loss.

For several years, Proteika was synonymous with success for all those who wanted to lose weight quickly through proteins. Formerly known as Pro'gram 18, the brand had built its reputation on a simple but effective method: a Proteika protein diet based on products high in protein and very low in sugars and fats.

The principle was clear: by drastically reducing carbohydrates, the body was forced to draw its energy from stored fats. Thanks to this strategy, the Proteika diet enabled rapid weight loss while protecting muscle mass.

This type of low-calorie diet acted directly on metabolism, by reducing daily caloric intake and increasing satiety through proteins.

The Proteika protein diet was not improvised. It took place in several stages, starting with an attack phase designed to quickly trigger weight loss. Then came a transition phase, where certain foods were gradually reintroduced, followed by a stabilization phase to maintain the results.

This organization made it possible to maintain a clear framework and support users throughout their weight loss journey.

The effectiveness of Proteika diet was also based on its range of high-protein products. It included:

• Proteika protein sachets in the form of drinks, desserts or soups,

• gourmet bars and cookies,

• savory snacks such as chips or crackers,

• quick preparations for complete meals.

These products were designed to be both filling and tasty. They made following the diet easier on a daily basis, without hunger or frustration.

Despite its recognized effectiveness, the Proteika brand eventually disappeared. Its acquisition led to the discontinuation of its activities and its products are no longer marketed. However, the Proteika diet continues to generate great interest. Many people remember its results and are still looking to find the famous Proteika proteins that made this method successful.

Even though the brand no longer exists, Proteika remains associated in the minds of many consumers with an effective high-protein diet. Today, you can find products similar to Proteika proteins by choosing Cétofine 21 high-protein products: 18 grams of protein per high-protein sachet.

These protein-rich foods:

• act as a natural appetite suppressant
• reduce appetite
• facilitate weight loss (targeted only at fat mass).

The disappearance of Proteika does not mean the end of this type of program. Cétofine 21 has taken on the concept and perfected it. Our French laboratory, specialized in high-protein dietetics since 1996, now offers an even more complete slimming method and products very similar to those offered by Pro'gram 18 Proteika.

While the Proteika diet was based on three major phases, Cétofine 21 has chosen to go further by implementing a four-stage process. Indeed, we have reworked the high-protein diet with the help of nutritionists by adding a Stabilization phase. This way, you will avoid the yo-yo effect.

This weight loss program allows you to lose weight without losing muscle, adopt new eating habits, and maintain a permanent healthy weight. Here are the 4 stages that make up the high-protein diet:

1. Strict diet: rapid weight loss through protein sachets and authorized vegetables.

2. The mixed diet: continuation of weight loss with a balanced meal as a complement.

3. Transition: gradual reintroduction of traditional foods.

4. Stabilization: consolidation of results and return to a varied and balanced diet.

The addition of this Stabilization phase limits the risk of weight regain, where the Proteika protein diet could sometimes lack long-term support.

The goal is to learn how to return to a balanced diet, by gradually reintroducing starches, fruits and vegetables, as well as low-fat dairy products such as yogurt or cottage cheese.

The strength of Cétofine 21 lies in its range of protein-rich products. We now offer the equivalent of the former Proteika proteins:

• sweet high-protein sachets (cocoa, coffee, desserts, entremet),

• savory sachets (soups, omelettes, complete meals),

• protein bars and biscuits for snacking,

• tasty snacks such as wafers, chips, and crackers,

• hot and cold protein-rich drinks.

Each high-protein sachet is designed to provide a good nutritional balance, with enough protein (18 grams), vitamins and minerals, while remaining low in calories and suitable for a low-calorie diet.

To tell you more about proteins. All our products are made with high biological value proteins, particularly from milk, soy, or eggs, with a chemical index above 100. This ensures effectiveness, digestibility, and pleasure.

With Cétofine 21, you'll find the effectiveness that made Proteika famous:

• a structured and supervised protein diet,

• tasty and varied products,

• rapid weight loss targeted at fat mass,

• a method designed to protect muscle mass.

Many customers notice a better feeling of satiety, a flatter stomach and the disappearance of excess pounds within the first few weeks.

Unlike Proteika, which has now disappeared, Cétofine 21 is available online and offers personalized support. Our nutrition advisors answer your questions for free before, during, and after your diet. Delivery is fast, and our varied ranges allow you to follow a program without monotony.

Thanks to tailored slimming meals, meal replacements with no added sugar, and available gluten-free products, Cétofine 21 allows you to follow a balanced and sustainable diet.

The Proteika diet, formerly Pro'gram 18 Proteika, marked an entire generation of people seeking rapid weight loss through protein. Although the brand has disappeared, protein products still exist today thanks to Cétofine 21.

With a comprehensive four-step process, a wide range of protein products comparable to the former Proteika proteins, and personalized support, Cétofine 21 is now the true alternative for those who were looking for the Proteika diet.
