Ketogenic and low-carbohydrate Diets in People with Cancer

摘要

For several years, people with cancer have been offered so-called "cancer diets" that are low-carb or ketogenic to varying degrees. The reason given for these diets is that the metabolism of tumor cells is dependent on carbohydrates. Depending on the interpretation of the study data, these diets promise a direct influence on tumor growth (and metastasis) as well as an improvement in the effectiveness and tolerability of chemotherapy and/or radiotherapy (especially chemotherapy). However, there is a lack of methodologically high-quality studies and thus reliable evidence for the ketogenic diet. For this reason, the authors of the analysis come to the conclusion that the use of a low-carbohydrate or ketogenic diet for this indication must be discouraged at this time.
