Fad diets for non-dialysis chronic kidney disease patients: Can "the miracle diet" be a threat?

Abstract

In the pursuit of an effortless "miracle cure", there has been a significant increase in the proliferation of fad diets. These diets generally exclude a food group or macronutrients and may also restrict energy intake; they become popular quickly but often lack substantial scientific evidence to support their efficacy and safety. They only show short-term results rather than promoting a lifestyle change. Fad diets are nutritionally unbalanced and can be dangerous for some individuals. Most fad diets are generally restrictive in carbohydrates, high in protein, or unbalanced and have low energy intake, which can harm patients with early stages of chronic kidney damage (CKD) who need a low-protein diet with adequate energy intake. This narrative review discusses the risk of fad diet prescriptions for non-dialysis CKD patients.
