Abstract

We examined the effectiveness and problems associated with a low-carbohydrate diet and whether or not patients can practice and continue such treatment based on the influence on the serum lipid profile and patients' psychological burden. The subjects were 30 patients with type 2 diabetes who were examined in a randomized cross over comparison study of an energy-controlled diet versus a low-carbohydrate diet. The amount of energy was set as equal to the standard weight × physical activity amount (25 to 30 kcal/kg) in the two diet regimen groups, and the PFC (protein: fat: carbohydrate) ratio in the low-carbohydrate diet group was set to 30:30:40. The energy intake did not markedly differ between the groups. The carbohydrate intake was significantly lower and the lipid intake significantly greater in the low-carbohydrate diet group than in the energy-controlled diet group. The improvement in the HbA1c was greater in the low-carbohydrate diet group than in the energy-controlled diet group. The serum lipid profile, including RLP-C, RLP-TG, GSES, and PAID, also did not differ markedly between the groups. These results suggest that a mild low-carbohydrate diet with a carbohydrate energy ratio of 45.6 % may be an effective treatment method that patients can practice and continue.
