Summary

Kidney transplant recipients (KTR) have a considerably lower life expectancy as compared with the general population, primarily due to a high prevalence of cardiovascular diseases. KTR often develop an unfavourable cardio-metabolic risk profile characterized by weight gain, metabolic syndrome and post-transplantation diabetes mellitus (PTDM). In general, nutrition plays a key role in both the prevention and treatment of these cardio-metabolic derangements.

However, in KTR most RCT's with a dietary intervention, failed to show significant improvement in cardio-metabolic health. This at least questions the efficacy of the diets of these intervention, which relied on general or diabetes guidelines, after kidney transplantation. KTR not only face a high cardio-metabolic risk, but also have a high risk for malnutrition and muscle mass depletion. More knowledge is required to determine the optimal diet and macronutrient composition for improvement of the cardio-metabolic risk factors in the context of the high malnutrition risk. In this regard, observational studies point towards the needs for a higher protein intake for better patient outcomes. Therefore, in this study, the investigators will examine if a high-protein, carbohydrate-reduced diet is more effective than a diet in line with the Dutch Dietary Guidelines for improvement of cardio-metabolic risk factors and for improvement of the body composition in KTR.

Conditions

  • Kidney Transplant; Complications

Interventions

OTHER

high-protein, carbohydrate-reduced diet

the high-protein, carbohydrate-reduced diet will consist of 1.2-1.4 g/kg/d protein, 26-20en% carbohydrates and +/- 50en% fatty acids, with mainly unsaturated fatty acids. This diet consist of mainly unprocessed, fresh nutrient-dense food-products. Ultra-processed foods and alcoholic beverages will be totally avoided. Salt consumption will not exceed 5-6 g/d. The diet is ad libitum and caloric restriction will not be applied. The diet will be followed for 6 weeks.

OTHER

Dutch Nutritional Guidelines

the diet according to the Dutch Nutritional Guidelines will consist of a protein intake of 0.8-1.0 g/kg/d and 50-60en% carbohydrates, and +/-30en% fatty acids, with restriction of saturated fatty acids \<10en%. This diet consist of mainly unprocessed, fresh nutrient-dense food-products. Ultra-processed foods and alcoholic beverages will be totally avoided. Salt consumption will not exceed 5-6 g/d. The diet is ad libitum and caloric restriction will not be applied. The diet will be followed for 6 weeks.
