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

Summary

The investigators hypothesize that weight loss obtained with the French RNPC weight reduction program is beneficial for the general health of overweight/obese patients in the medium term.

The objective of this cohort study is to demonstrate the effectiveness of the RNPC program on the reduction of drug or instrumental treatments (for example, continuous positive pressure ventilation for the treatment of sleep apnea syndrome) and the improvement of overweight/obesity-associated comorbidities in the medium term.

This is a multicenter clinical study, as part of routine care, with standardized nutritional care (RNPC Program) in all RNPC centers in France. A cohort will be formed based on the clinical and biological data usually collected in the centers, enriched by data from additional clinical and biological examinations as well as by self-questionnaires completed by the participants. About 10,000 overweight or obese participants will be included for 2 years and followed 5 years.

The SCOOP-RNPC study will have benefits for individual participants, for the scientific community in terms of knowledge acquired and for society with a better definition of the impact of treatments.

Responding to the major public health issue represented by overweight, this prospective cohort of overweight or obese patients will make it possible to evaluate, in real-life conditions, the effects of weight loss obtained by the RNPC Program in the short, medium and long term on biological parameters predictive of cardiometabolic risk, drug consumption, quality of life, diet and eating behavior, sleep, physical activity, stress/anxiety, as well as depression.

This cohort will make it possible to identify clinical phenotypes and biomarkers to optimize the personalization of the management of overweight or obese patients, in particular those at risk of developing comorbidities associated with excess weight.

Interventions

BEHAVIORAL

Nutritional Psycho-Behavioral Reeducation Program

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.
