Study Consortium for Evaluation of RNPC Program in Obese and Overweight Patients (SCOOP-RNPC)

"The RNPC Program is based on a clinical protocol in three successive phases:~1. A weight loss phase during which food intake is restricted to 800-1000 kcal per day, with a nutrient distribution of 60% protein, 25% carbohydrates and 15% lipids. Patients eat two meals a day consisting of meat/fish/eggs/shellfish and vegetables, supplemented by products enriched in proteins, vitamins and minerals, and depleted in carbohydrates and lipids.~2. A stabilization phase specifically established for each patient according to their weight loss and their daily caloric needs, allowing them to gradually return to a balanced diet, with a nutrient distribution of 25% protein, 45% carbohydrates and 30% lipids. During this phase, the consumption of meal supplements gradually decreases.~3. A phase of return to dietary balance, unlimited in time, based on the precepts of the Mediterranean diet.~Each patient is followed every 14 days by a dietitian during the entire program."
