The South African public are currently very interested in the use of a low carbohydrate, high fat (LCHF) diet for weight loss, blood glucose control and managing high cholesterol levels. Dietitians are receiving more and more enquiries from the public on their opinion about the safety and efficacy of the diet. This study investigated whether KwaZulu-Natal (a province of South Africa) dietitians prescribe the diet, who they would prescribe it for, and their thoughts and concerns regarding the diet.
