Pronokal Diet

The PronoKal® Method is a personalised weight loss program under medical supervision based on a Protein Diet. The aim is not only to lose weight, but to maintain the results in the long-term. To achieve this maintenance, we need to change our approach to food; we also need the continual support of Pronokal’s multidisciplinary patient monitoring team, even after reaching the weight loss goal.


Through the PronoKal® Method, patients choose to change their habits for a healthier lifestyle.

Throughout the process, patients are supported by a full multidisciplinary team of:

  • doctors
  • dietitians
  • technicians in physical activity
  • experts in coaching (emotional reinforcement), who help to achieve short and long-term weight loss goals.


According to the latest results from the ProKal Study, the PronoKal® Method has proved to be a more efficient method of losing weight than a low-calorie diet:

PronoKal® Method Indications

The PronoKal® Method is suitable for all those who want to lose weight and keep it down in the long term.

When your body carries more weight than it needs, it can increase your risk of developing cardiovascular risk factors, such as high blood pressure and raised cholesterol levels and insulin resistance. Not only that, but it can also affect mood and vitality. By losing excess weight we can regain wellness, improve health and achieve the image we desire.

When we decide to lose weight, we should put ourselves in the hands of a professional. Medical management is essential to the treatment. Doctors who prescribe the PronoKal® Method set weight loss targets, check the patient’s metabolic status and can rule out possible contraindications.

How does it work?

PronoKal® Method Stages

The method is divided into three stages: Active, Stabilisation and Maintenance. In the first stage, the Active Stage, duration varies according to the weight loss that is required. This is when 80% of excess weight is lost by combining PronoKal® products with permitted foods.

At this stage, the patient enters a state of controlled ketosis in which the body expends its energy reserves due to a low intake of fats and carbohydrates. Weight is lost at the expense of accumulated fat, whilst preserving the muscle mass.

In the next stage, Stabilisation, the remaining weight (20% of excess weight) is lost while all kinds of foods are gradually introduced into the diet. Just as importantly, new dietary and lifestyle habits are acquired that will help maintain weight loss in the long term.

During the laststage –the Maintenance Stage– the patient, after reaching their target weight, is regularly monitored to help to maintain his or her long-term weight goal. This stage is adapted to the energy characteristics of each patient and combines traditional food products and PronoKal® Maintenance products.

From the start, and up to two years after the end of treatment, the patient receives the support and advice from the PronoKal® team of dietitians, experts in physical activity and experts in coaching (emotional reinforcement).
