- Price of the medical consultations may vary if external collaborating doctors are used
- Additional blood tests may be requested in the 10-week and 14-week programmes.
- The minimum price is calculated using only the sachets (cheapest meal products). The max price is calculated using the maximum allowance of 3 ready-to-eat meal products with 2 sachets. Both prices include the supplements.
- The typical range of weight loss is shown for men and women. The rate and extent of weight loss varies with sex and age and with individual characteristics.
- The programme includes free long-term follow-up online for up to 2 years for completers of a full programme, designed to help patients become self-reliant and to help cope with any weight regain. This dedication to patients’ long-term success is unique to PronoKal UK and helps to prevent weight regain. The 2-year duration is based on studies that show that patients who achieve a stable weight for 2 years after weight loss have a much higher probability of staying weight-stable in the long-term.
Why does the PronoKal PnK programme cost more than some other weight management programmes in the initial phases?
It is true that the PronoKal PnK programme costs more than many other weight management programmes in the initial phases
PronoKal costs more due to its personalized approach, specific products (protein foods), constant medical supervision, body composition monitoring, free long-term support, and the technology behind its ketogenic methodology, all wrapped in a premium brand that offers a comprehensive "method," unlike cheaper generic diets that don't have the same monitoring structure and products designed for ketosis.
This brings numerous benefits:
- Rapid and effective weight loss
- PronoKal has undertaken clinical studies that show the very high quality of weight loss, defined as a higher proportion of fat loss and less muscle wasting
- PronoKal uses a very low calorie ketogenic diet, shown to improve the markers of liver function and to reduce liver fat faster than low-calorie diets
- It has been shown to be a safe and valuable tool for the treatment of obesity with type 2 diabetes
- The programme includes free long-term follow-up for up to 2 years. As far as we are aware, this dedication to patients' long-term success is unique. The 2-year duration is based on studies that show that patients who achieve a stable weight for 2 years after weight loss have a much higher probability of staying
