What is the Role of Carbohydrate-Restricted Diets for Patients with Obesity-Related Diseases (Hyperlipidemia, Diabetes, Hypertension, etc)?

Compared with low-fat diets, carbohydrate-restricted diets (eg, Atkins) produce more weight loss in the short term (at 6 months but not at 1 year) and produce a greater reduction in glycosylated hemoglobin (HbA1C). (SOR A, based on a meta-analysis.) However, no studies have been published with more than 1 year duration or have focused on patient-oriented outcomes. The American Diabetes Association now recommends either low-carbohydrate or low-fat calorie-restricted diets for weight loss over the short term. (SOR C, based on expert opinion.)
