PronoKal Group is a multinational company specialising in medical weight-loss treatments based on comprehensive prorgammes involving an array of profesionals (doctors, dieticians-nutritionists, physical trainers, coaches, etc.). The primary mission of the PronoKal Group is to offer effective solutions to help the patients to reach their weight-loss goal and maintain the results over time, thus enabling a better quality of life and greater sense of well-being, as well as to aid in the prevention of overweight and obesity. It began its activities in 2004 with the launch in Spain of the PronoKal Method, the first medically supervised multidisciplinary treatment for weight loss based on the protein diet, which helped this company to become a reference model in this area. Currently, PronoKal Group has different medical treatments for weight loss and long-term maintenance, based on a protein diet, suited to different patient profiles (PronoKal Method, PnK Method, DiaproKal Method). Since 2009, the expansion and internationalization process of the PronoKal Group has been consolidated: PronoKal Group® is now present in 15 countries, with three administrative headquarters in Europe (Geneva, Luxembourg and Barcelona). The success of our medical treatments is substantiated by 450,000 patients treated and 4,000 prescribing doctors who trust in the rigour and effectiveness of our methods. These figures make PronoKal Group the top company in our sector. Since its inception, the company has committed itself to rigour and science, launching numerous studies to demonstrate the efficacy and safety of a Protein Diet versus a low calorie diet. So far over 15 studies have been conducted, half of which have been published and presented at international scientific meetings.
