Aim: To identify core diet and delivery components of low‐carbohydrate (CHO) diets that have demonstrated efficacy for type 2 diabetes (T2D) management. Materials and methods: MEDLINE, Pre‐MEDLINE, EMBASE, CINAHL and the Cochrane Library of Controlled Trials databases were systematically searched from inception until August 18, 2018. Primary intervention studies of low‐CHO diets (≤130 g/d or 26% total energy intake [TEI]) were included. Content analysis was performed on the low‐CHO diet protocols classified as safe and effective for T2D management. Results: A total of 41 studies published between 1963 and 2018 were included, of which 40 were classified as safe and effective for inclusion in the primary analysis. Thirteen studies (13/40) were on very‐low‐CHO diets (<50 g/d), 14/40 included low‐CHO diets (≤130 g/d or 26% TEI), and 13/40 were adapted according to participant progress. Thirty‐one studies reported a total energy prescription, of which 18/31 encouraged ad libitum intakes. Twenty studies reported a prescribed dietary fat amount, of which 18/20 were unrestricted or high‐fat (>35% TEI). Twenty‐six studies reported a prescribed dietary protein amount, of which 22 were unrestricted or were high‐protein (>25% TEI). The types of dietary CHO, fat and protein recommended were predominantly whole foods. Common delivery methods reported were dietician and/or physician involvement, moderate to high frequency of contact (≥1 session/month) and use of participant self‐monitoring. Conclusions: Multiple approaches for developing and delivering a low‐CHO diet intervention for T2D management are safe and effective. A comprehensive set of core dietary components to consider in the formulation of low‐CHO diet protocols were identified for use in clinical practice and to inform evidence‐based guidelines for T2D management.
